Binding Elements

You can "bind" elements inside of a controller for easier access in your controller code.

This will bind the p element to your controller under this.binds.paragraph:

<some-controller>
    <p :bind="paragraph">Hello, World</p>
</some-controller>

This is effectively just a shorthand for this.binds.paragraph = this.querySelector("p");

If you store multiple elements under the same key then they will be stored in a list:

<some-controller>
    <p :bind="paragraph">Hello, One</p>  <!-- this.binds.paragraph[0] -->
    <p :bind="paragraph">Hello, Two</p>  <!-- this.binds.paragraph[1] -->
    <p :bind="paragraph">Hello, Three</p>  <!-- this.binds.paragraph[2] -->
</some-controller>
