Basic Access Methods — ClassName, TagName, and Name

Quick Start (30 Seconds)

javascript

// Access a group of elements — pick the method that fits your HTML:

// By CSS class → most common
const buttons = Collections.ClassName.btn;

// By HTML tag → target all elements of a type
const paragraphs = Collections.TagName.p;

// By name attribute → form element groups
const emailInputs = Collections.Name.email;

// Now use them like arrays
buttons.forEach(btn => console.log(btn.textContent));
// Output: Save, Cancel, Delete

// Or apply bulk changes to all at once
buttons.addClass('ready').setProperty('disabled', false);

Three ways in, all returning the same powerful collection object. Pick the one that matches your HTML.

What Are the Three Access Methods?

The Collections Helper has three "doors" into the DOM, each finding elements a different way:

Method	How It Finds Elements	Best For
`Collections.ClassName`	CSS class attribute	Styled groups: buttons, cards, list items
`Collections.TagName`	HTML tag type	Semantic targets: all `<p>`, all `<img>`, all `<input>`
`Collections.Name`	`name` attribute	Form groups: radio buttons, checkboxes, repeated inputs

All three return the same thing: an Enhanced Collection — an array-like object with every array method plus built-in DOM methods.

Syntax

javascript

// === ClassName ===

// Property access (recommended — simple names)
const collection = Collections.ClassName.className;

// Bracket notation (required for hyphenated names)
const collection = Collections.ClassName['class-name'];

// Method call (works for any name)
const collection = Collections.ClassName('className');
const collection = Collections.ClassName('class-name');


// === TagName ===

// Property access (lowercase tag name)
const collection = Collections.TagName.tagname;

// Method call
const collection = Collections.TagName('tagname');


// === Name ===

// Property access
const collection = Collections.Name.attributeName;

// Bracket notation (for hyphenated names)
const collection = Collections.Name['attribute-name'];

// Method call
const collection = Collections.Name('attributeName');

Why Do These Three Methods Exist?

`Collections.ClassName` — When Styling Groups Is Your Priority

In modern HTML, elements are often grouped by their CSS class. A row of cards, a group of action buttons, a set of form fields — they all share a class. ClassName is designed exactly for this situation.

javascript

// HTML:
// <button class="btn">Save</button>
// <button class="btn">Cancel</button>
// <button class="btn">Delete</button>

const buttons = Collections.ClassName.btn;

// Update them all instantly
buttons.addClass('active')
       .setStyle({ backgroundColor: '#2563eb' });

This method is great when you need: ✅ The most common collection type in UI development ✅ Accessing elements by their visual or semantic role ✅ Groups where elements share a purpose (all "card" elements, all "btn" elements) ✅ Both simple names (btn) and hyphenated names (user-card)

`Collections.TagName` — When Tag Type Is Your Priority

Sometimes you want all elements of a specific HTML type regardless of their class. All images, all links, all inputs, all paragraphs. TagName is the direct way to do that.

javascript

// HTML: any combination of <a> tags on the page

const links = Collections.TagName.a;

// Make all external links open in new tab
links.setAttribute('target', '_blank')
     .setAttribute('rel', 'noopener noreferrer');

This method is especially useful when: ✅ Targeting all elements of a type regardless of their class ✅ Applying accessibility attributes across all instances of a tag ✅ Semantic operations — "all images", "all inputs", "all links" ✅ When elements don't have or need a distinguishing class

`Collections.Name` — When Form Grouping Is Your Priority

In forms, related inputs share a name attribute — especially radio buttons and checkboxes. Collections.Name finds them all together, making group operations trivial.

javascript

// HTML:
// <input type="radio" name="color" value="red">
// <input type="radio" name="color" value="blue">
// <input type="radio" name="color" value="green">

const colorOptions = Collections.Name.color;

// Find which one is selected
const selected = colorOptions.find(r => r.checked);
console.log('Chosen:', selected?.value); // 'blue' (or whichever)

This method is especially useful when: ✅ Working with radio button groups ✅ Working with checkbox groups ✅ Multiple inputs sharing the same name in a form ✅ Querying which value is currently selected

The Choice Is Yours:

Use ClassName when elements share a CSS class
Use TagName when you want all elements of a specific HTML type
Use Name when you're working with named form element groups
All three are valid and can be combined freely in the same page

1. Collections.ClassName — Deep Dive

Basic Usage

html

<button class="btn">Save</button>
<button class="btn">Cancel</button>
<button class="btn">Delete</button>

javascript

// Get all elements with class="btn"
const buttons = Collections.ClassName.btn;

// How many?
console.log(buttons.length); // 3

// Read their text content
buttons.forEach((btn, index) => {
  console.log(`Button ${index + 1}: ${btn.textContent}`);
});
// Output:
// Button 1: Save
// Button 2: Cancel
// Button 3: Delete

What's happening:

Collections.ClassName.btn tells the library "find all elements with class="btn" in the current DOM"
The result is an Enhanced Collection with 3 elements
forEach works just like on a regular array — index is the position, btn is the actual DOM element

Handling Multi-Word (Hyphenated) Class Names

CSS classes often use hyphens: user-card, nav-link, submit-btn. You can't use dot notation for these — use bracket notation or the method call.

html

<div class="user-card">Alice</div>
<div class="user-card">Bob</div>
<div class="user-card">Charlie</div>

javascript

// ❌ Won't work — hyphens break dot notation in JavaScript
// Collections.ClassName.user-card

// ✅ Bracket notation — recommended for hyphenated names
const cards = Collections.ClassName['user-card'];
console.log(cards.length); // 3

// ✅ Method call — also works
const cards2 = Collections.ClassName('user-card');
console.log(cards.length === cards2.length); // true

Simple rule: Use dot notation for simple names. Use bracket notation ['class-name'] when there's a hyphen.

Examples

Example 1: Highlight All Cards

html

<div class="card">Product A - $19.99</div>
<div class="card">Product B - $29.99</div>
<div class="card">Product C - $9.99</div>

javascript

const cards = Collections.ClassName.card;

// Add visual styles to all cards at once
cards.setStyle({
  padding: '20px',
  borderRadius: '8px',
  boxShadow: '0 2px 6px rgba(0,0,0,0.1)',
  transition: 'transform 0.2s'
});

// Add hover interaction to all cards
cards.on('mouseenter', function() {
  this.style.transform = 'translateY(-4px)';
});

cards.on('mouseleave', function() {
  this.style.transform = 'translateY(0)';
});

// Mark them all as initialized
cards.addClass('initialized');

What happened: Three separate operations (style, mouseenter listener, mouseleave listener) applied to every card — no manual loops needed.

Example 2: Toggle Section Visibility

html

<section class="collapsible">Section 1 content...</section>
<section class="collapsible">Section 2 content...</section>
<section class="collapsible">Section 3 content...</section>

javascript

const sections = Collections.ClassName.collapsible;

// Show all sections
function showAll() {
  sections.removeClass('hidden').addClass('visible');
}

// Hide all sections
function hideAll() {
  sections.addClass('hidden').removeClass('visible');
}

// Toggle all sections
function toggleAll() {
  sections.toggleClass('collapsed');
  // Each section: if it has 'collapsed' → removes it. If it doesn't → adds it.
}

Example 3: Bulk Form Reset

html

<input class="form-field" type="text" name="username">
<input class="form-field" type="email" name="email">
<input class="form-field" type="password" name="password">

javascript

const fields = Collections.ClassName['form-field'];

function resetForm() {
  // Clear all values
  fields.setProperty('value', '');

  // Remove error and success states
  fields.removeClass('error').removeClass('success');

  // Re-enable all fields
  fields.setProperty('disabled', false);

  console.log(`Reset ${fields.length} form fields`);
}

When to Use ClassName

✅ Use ClassName when:

Elements are grouped by a shared CSS class
You're working with UI components (cards, buttons, form fields, tabs)
The class name describes their role or style

Consider alternatives when:

Elements are all the same HTML tag with no class → TagName is more natural
Elements are grouped by a form name attribute → Name is the right tool
You need one specific element by its id → use the Elements Helper

2. Collections.TagName — Deep Dive

Basic Usage

html

<p>First paragraph about DOMHelpers.</p>
<p>Second paragraph with more details.</p>
<p>Third paragraph with examples.</p>

javascript

// Get all <p> elements on the page
const paragraphs = Collections.TagName.p;

console.log(paragraphs.length); // 3

// Apply consistent typography to all paragraphs
paragraphs.setStyle({
  lineHeight: '1.7',
  marginBottom: '16px',
  color: '#374151'
});

Important: TagName searches the entire document for that tag type. If you have <p> tags in multiple sections, they're all included.

Common Tags Reference

javascript

const paragraphs  = Collections.TagName.p;        // <p>
const divs        = Collections.TagName.div;       // <div>
const buttons     = Collections.TagName.button;    // <button>
const inputs      = Collections.TagName.input;     // <input>
const links       = Collections.TagName.a;         // <a>
const images      = Collections.TagName.img;       // <img>
const listItems   = Collections.TagName.li;        // <li>
const spans       = Collections.TagName.span;      // <span>
const headings    = Collections.TagName.h2;        // <h2>
const selects     = Collections.TagName.select;    // <select>
const textareas   = Collections.TagName.textarea;  // <textarea>

Examples

Example 1: Style All Links

javascript

const links = Collections.TagName.a;

// Apply base link styles
links.setStyle({
  color: '#2563eb',
  textDecoration: 'none',
  transition: 'color 0.2s'
});

// Add underline on hover
links.on('mouseenter', function() {
  this.style.textDecoration = 'underline';
});

links.on('mouseleave', function() {
  this.style.textDecoration = 'none';
});

// Make external links open in new tab
const externalLinks = links.filter(link => {
  const href = link.getAttribute('href') || '';
  return href.startsWith('http://') || href.startsWith('https://');
});

externalLinks.forEach(link => {
  link.setAttribute('target', '_blank');
  link.setAttribute('rel', 'noopener noreferrer');
});

What happened: We got all links, applied styles to all, then filtered to just external links and configured those separately.

Example 2: Lazy Loading for All Images

html

<img src="/images/hero.jpg" alt="Hero image">
<img src="/images/product1.jpg" alt="Product 1">
<img src="/images/product2.jpg" alt="Product 2">

javascript

const images = Collections.TagName.img;

// Set lazy loading on all images at once
images.setAttribute('loading', 'lazy')
      .setAttribute('decoding', 'async');

// Accessibility check — find images missing alt text
const noAlt = images.filter(img => !img.getAttribute('alt'));
if (noAlt.length > 0) {
  console.warn(`${noAlt.length} images are missing alt text!`);
}

Example 3: Disable/Enable All Form Controls

javascript

const inputs = Collections.TagName.input;
const buttons = Collections.TagName.button;
const selects = Collections.TagName.select;

function disableAllFormControls() {
  inputs.setProperty('disabled', true);
  buttons.setProperty('disabled', true);
  selects.setProperty('disabled', true);
  console.log('All form controls disabled');
}

function enableAllFormControls() {
  inputs.setProperty('disabled', false);
  buttons.setProperty('disabled', false);
  selects.setProperty('disabled', false);
  console.log('All form controls enabled');
}

Example 4: Validate All Required Inputs

javascript

const inputs = Collections.TagName.input;

// Find inputs that are required AND empty
const emptyRequired = inputs.filter(input =>
  input.hasAttribute('required') && !input.value.trim()
);

if (emptyRequired.length > 0) {
  // Highlight them all
  emptyRequired.forEach(input => {
    input.style.borderColor = '#ef4444';
    input.setAttribute('aria-invalid', 'true');
  });
  console.error(`${emptyRequired.length} required fields are empty`);
} else {
  console.log('All required fields are filled');
}

When to Use TagName

✅ Use TagName when:

Targeting all elements of a specific HTML type
Applying accessibility attributes across all instances
Setting global styles for a tag type
Elements don't have or need a distinguishing class

Consider alternatives when:

You want a subset of a tag type (e.g., "buttons with class primary") → Use ClassName
Elements are grouped by a form name → Use Name
You need one specific element → Use Elements Helper

3. Collections.Name — Deep Dive

Basic Usage

html

<input type="radio" name="size" value="small"> Small
<input type="radio" name="size" value="medium"> Medium
<input type="radio" name="size" value="large"> Large

javascript

// Get all elements with name="size"
const sizeOptions = Collections.Name.size;

console.log(sizeOptions.length); // 3

// Find which radio is currently selected
const selected = sizeOptions.find(radio => radio.checked);
console.log('Selected size:', selected?.value);
// Output: "Selected size: medium" (or whichever is checked)

Working with Radio Button Groups

Radio buttons sharing the same name are mutually exclusive — selecting one deselects the others. Collections.Name gives you the whole group at once.

html

<label><input type="radio" name="plan" value="free"> Free</label>
<label><input type="radio" name="plan" value="pro"> Pro</label>
<label><input type="radio" name="plan" value="enterprise"> Enterprise</label>

javascript

const planOptions = Collections.Name.plan;

// Get the currently selected plan
function getSelectedPlan() {
  const selected = planOptions.find(radio => radio.checked);
  return selected ? selected.value : null;
}

// Set a specific plan as selected programmatically
function selectPlan(planValue) {
  planOptions.forEach(radio => {
    radio.checked = radio.value === planValue;
    // Only the matching radio gets checked = true
  });
}

// React to selection changes
planOptions.on('change', () => {
  console.log('Plan changed to:', getSelectedPlan());
});

// Check initial state
console.log('Current plan:', getSelectedPlan());
// Output: "Current plan: free" (or whichever is currently checked)

Working with Checkbox Groups

Multiple checkboxes can share the same name to form a logical group. Users can select multiple options.

html

<label><input type="checkbox" name="feature" value="wifi"> WiFi</label>
<label><input type="checkbox" name="feature" value="parking"> Parking</label>
<label><input type="checkbox" name="feature" value="pool"> Pool</label>
<label><input type="checkbox" name="feature" value="gym"> Gym</label>

javascript

const features = Collections.Name.feature;

// Get all currently selected features
function getSelectedFeatures() {
  return features
    .filter(cb => cb.checked)
    .map(cb => cb.value);
}
// Returns something like: ['wifi', 'pool']

// Select all features at once
function selectAll() {
  features.setProperty('checked', true);
  console.log('All features selected');
}

// Clear all selections at once
function clearAll() {
  features.setProperty('checked', false);
  console.log('All features cleared');
}

// Toggle each feature
function toggleAll() {
  features.forEach(cb => {
    cb.checked = !cb.checked;
  });
}

// Check if at least one is selected
function hasSelection() {
  return features.some(cb => cb.checked);
}

console.log('Selected features:', getSelectedFeatures());
// Output: "Selected features: ['wifi', 'pool']"

Examples

Example 1: Dynamic Radio Group with Live Preview

html

<div id="colorPicker">
  <input type="radio" name="color" value="red"> Red
  <input type="radio" name="color" value="green"> Green
  <input type="radio" name="color" value="blue"> Blue
</div>
<div id="colorPreview" style="width: 100px; height: 100px;"></div>

javascript

const colorOptions = Collections.Name.color;
const preview = Elements.colorPreview;

// Update preview whenever selection changes
colorOptions.on('change', function() {
  // `this` is the radio button that was just changed
  preview.style.backgroundColor = this.value;
  console.log('Color set to:', this.value);
});

// Select a specific color programmatically
function selectColor(colorValue) {
  colorOptions.forEach(radio => {
    radio.checked = radio.value === colorValue;
  });
  preview.style.backgroundColor = colorValue;
}

selectColor('blue');
// Blue radio is now checked, preview turns blue
// Console: "Color set to: blue"

Example 2: Multi-Checkbox Preferences Form

html

<p>Notification preferences:</p>
<label><input type="checkbox" name="notify" value="email"> Email</label>
<label><input type="checkbox" name="notify" value="sms"> SMS</label>
<label><input type="checkbox" name="notify" value="push"> Push notifications</label>

javascript

const notifyOptions = Collections.Name.notify;

// Get selected values ready for API submission
function getPreferences() {
  const selected = notifyOptions
    .filter(cb => cb.checked)
    .map(cb => cb.value);

  return { notifications: selected };
}

// Pre-populate from saved settings
function loadPreferences(savedValues) {
  notifyOptions.forEach(cb => {
    cb.checked = savedValues.includes(cb.value);
  });
}

// Usage
loadPreferences(['email', 'push']);
// 'email' and 'push' checkboxes are now checked

console.log(getPreferences());
// Output: { notifications: ['email', 'push'] }

Example 3: Multiple Text Inputs with the Same Name

html

<input type="text" name="tag" placeholder="Tag 1">
<input type="text" name="tag" placeholder="Tag 2">
<input type="text" name="tag" placeholder="Tag 3">

javascript

const tagInputs = Collections.Name.tag;

// Collect all non-empty tag values
function getAllTags() {
  return tagInputs
    .map(input => input.value.trim())
    .filter(value => value !== '');
}

// Clear all tag inputs
function clearTags() {
  tagInputs.setProperty('value', '');
}

// Check if any tag has been entered
function hasTags() {
  return tagInputs.some(input => input.value.trim() !== '');
}

console.log('Current tags:', getAllTags());
// Output: "Current tags: ['javascript', 'css']" (filled ones only)

When to Use Name

✅ Use Name when:

Working with radio button groups
Working with checkbox groups
Multiple inputs sharing the same name attribute
Need to get or set values for an entire named group

Consider alternatives when:

Elements don't have a name attribute → Use ClassName or TagName
You need one specific input → Use Elements Helper

Comparing the Three Methods

	ClassName	TagName	Name
Finds by...	`class="btn"`	`<button>` tag	`name="email"`
Best for...	Styled groups	Tag-level operations	Form groups
Hyphenated names	Bracket notation	N/A	Bracket notation
Returns	Enhanced Collection	Enhanced Collection	Enhanced Collection
Cached	✅ Yes	✅ Yes	✅ Yes

Automatic Caching — How It Works

All three methods use the same caching system:

javascript

// First access — queries the DOM
const buttons1 = Collections.ClassName.btn;
// Under the hood: "Is 'class:btn' in cache? No → query DOM → store in cache"

// Second access — returns from cache instantly
const buttons2 = Collections.ClassName.btn;
// Under the hood: "Is 'class:btn' in cache? Yes → return cached collection"

// They are the same reference
console.log(buttons1 === buttons2); // true

// Performance difference
console.time('first-access');
const a = Collections.ClassName.btn;
console.timeEnd('first-access'); // ~0.5ms (DOM query)

console.time('second-access');
const b = Collections.ClassName.btn;
console.timeEnd('second-access'); // ~0.01ms (cache hit — 50x faster)

The cache is automatically invalidated when the DOM structure changes — using a MutationObserver internally. You don't need to manage it manually.

Static Snapshots — What This Means for You

Each access returns a static snapshot of the matching elements at that moment:

javascript

const items = Collections.ClassName.item;
console.log(items.length); // 3

// Add a new item to the DOM
const newItem = document.createElement('div');
newItem.className = 'item';
document.body.appendChild(newItem);

// The existing snapshot is unchanged
console.log(items.length); // Still 3

// Access again to get an updated snapshot
const freshItems = Collections.ClassName.item;
console.log(freshItems.length); // 4 — includes the new one

Why is this good? When you iterate with forEach, the collection won't change underneath you. Static snapshots keep iteration safe and predictable.

When you need fresh data: Simply access the collection again — Collections.ClassName.item — and you'll get an updated snapshot reflecting the current DOM.

Common Patterns

Pattern 1: Chain Multiple Operations

javascript

// Configure all buttons with one expression
Collections.ClassName.btn
  .addClass('initialized')
  .setProperty('disabled', false)
  .setStyle({ cursor: 'pointer' })
  .on('click', handleButtonClick);
// All four operations applied to every button ✨

Pattern 2: Filter Then Process

javascript

const buttons = Collections.ClassName.btn;

// Get only enabled buttons
const enabledButtons = buttons.filter(btn => !btn.disabled);

// Process just the enabled ones
enabledButtons.forEach(btn => {
  console.log('Active button:', btn.textContent);
});

console.log(`${enabledButtons.length} of ${buttons.length} buttons are active`);

Pattern 3: Extract Data from All Elements

javascript

const cards = Collections.ClassName.card;

// Extract structured data from each card
const cardData = cards.map(card => ({
  id: card.dataset.id,
  title: card.querySelector('h3')?.textContent,
  price: card.dataset.price
}));

console.log(cardData);
// Output: [{ id: '1', title: 'Item A', price: '19.99' }, ...]

Pattern 4: Combine Multiple Collections

javascript

// Get form fields using different methods
const textInputs = Collections.TagName.input;
const radioGroup = Collections.Name.size;
const checkGroup = Collections.Name.features;

// Disable everything at once
textInputs.setProperty('disabled', true);
radioGroup.setProperty('disabled', true);
checkGroup.setProperty('disabled', true);

Best Practices

✅ Store the Reference — Access Once, Use Many Times

javascript

// Good — access once, store, reuse
const buttons = Collections.ClassName.btn;
buttons.addClass('initialized');
buttons.on('click', handleClick);
buttons.setStyle({ cursor: 'pointer' });

javascript

// Clean — related operations chained together
Collections.ClassName.card
  .addClass('active')
  .setStyle({ opacity: '1' })
  .setAttribute('data-status', 'ready');

✅ Choose the Right Method

javascript

// Use ClassName for styled groups
const cards = Collections.ClassName.card;

// Use TagName for all-elements-of-type
const allLinks = Collections.TagName.a;

// Use Name for form groups
const radioGroup = Collections.Name.plan;

❌ Don't Access Collections in Tight Loops

javascript

// Avoid — accessing inside a loop is unnecessary
for (let i = 0; i < 100; i++) {
  Collections.ClassName.btn.forEach(btn => process(btn));
}

// Better — access once before the loop
const buttons = Collections.ClassName.btn;
for (let i = 0; i < 100; i++) {
  buttons.forEach(btn => process(btn));
}

❌ Don't Forget Bracket Notation for Hyphenated Names

javascript

// ❌ Will cause a JavaScript syntax error
// Collections.ClassName.nav-link

// ✅ Use bracket notation
const navLinks = Collections.ClassName['nav-link'];

// ✅ Or method call
const navLinks2 = Collections.ClassName('nav-link');

Real-World Example: Page Setup

Here's how all three methods work together in a real page initialization:

html

<!-- Navigation links -->
<a class="nav-link" href="/home">Home</a>
<a class="nav-link" href="/about">About</a>
<a class="nav-link" href="/contact">Contact</a>

<!-- Product cards -->
<div class="card" data-id="1" data-price="19.99">Product A</div>
<div class="card" data-id="2" data-price="29.99">Product B</div>

<!-- Quantity inputs -->
<input type="number" name="quantity" min="1" max="99" value="1">
<input type="number" name="quantity" min="1" max="99" value="1">

javascript

function initializePage() {
  // 1. Set up navigation with ClassName
  const navLinks = Collections.ClassName['nav-link'];
  navLinks.on('click', function(e) {
    navLinks.removeClass('active');       // Clear all active states
    this.classList.add('active');         // Set clicked one as active
  });

  // 2. Set up cards with ClassName
  const cards = Collections.ClassName.card;
  cards.setStyle({ cursor: 'pointer' })
       .on('click', function() {
         console.log('Card clicked, ID:', this.dataset.id);
       });

  // 3. Set up quantity inputs with Name
  const quantities = Collections.Name.quantity;
  quantities.on('change', function() {
    console.log('Quantity changed to:', this.value);
    updateCartTotal();
  });

  // 4. Ensure all images load lazily (TagName)
  Collections.TagName.img.setAttribute('loading', 'lazy');

  console.log('Page initialized:');
  console.log('  Nav links:', navLinks.length);
  console.log('  Cards:', cards.length);
  console.log('  Quantity inputs:', quantities.length);
}

initializePage();

Key Takeaways

Three access methods — ClassName, TagName, Name — each for a different HTML grouping
Same return type — all three give you an Enhanced Collection with array methods + DOM methods
Property access for simple names, bracket notation for hyphenated names
Automatically cached — first access is slower (DOM query), subsequent ones are instant
Static snapshots — collections don't auto-update; access again when you need fresh data
Chainable — all bulk methods return the collection, allowing clean method chaining
Choose the right method — ClassName for CSS groups, TagName for tag types, Name for form groups

What's Next?

With the three access methods mastered, explore what you can do with the collections they return:

Array-Like Methods — forEach, map, filter, find, some, every, reduce
DOM Manipulation Methods — addClass, setProperty, setStyle, on, off
Filtering Methods — visible(), hidden(), enabled(), disabled()
