Action Log

No actions yet...

1. $el

The Current Outfit Piece

$el refers to the current DOM element. It's like an item of clothing knowing about itself. An action on the element directly affects that same element.

Try it:

Code Snippet:

<button @click="$el.classList.toggle('styled')">
  This Shirt
</button>

2. $refs

Named Storage Areas

$refs lets you access other specific elements within your component by name. It's like a control panel to organize items in pre-defined, named storage areas.

The Closet:

👞 Shoe Rack
👒 Hat Shelf
👔 Tie Drawer

Control Panel:

Code Snippet:

<div x-ref="shoeRack">...</div>

<button @click="$refs.shoeRack.focus()">
  Select Shoes
</button>

3. $root

The Entire Closet

$root refers to the component's top-level element (the one with x-data). It's like an action that affects the entire closet structure, not just one piece or one area.

Try it:

Code Snippet:

<div x-data="...">
  <!-- This is the $root element -->
  <button @click="$root.classList.add('tidy')">
    Tidy Closet
  </button>
</div>
