ember-radio-button

ember-radio-button

This addon provides a radio-button component.

A radio-button will be in a checked state when the value property matches the groupValue property. value should be unique per radio-button, while the same groupValue should be provided to each radio-button in the group.

Clicking on a radio-button will set groupValue to its value.

Usage

Block Form

The block form emits a label wrapping the input element and any elements passed to the block.

Template:

{{#radio-button
    value="blue"
    groupValue=color
    changed="colorChanged"
}}
    <span>Blue</span>
{{/radio-button}}

/* results in */
<label id="ember346" class="ember-view ember-radio-button">
  <input id="ember347" class="ember-view" type="radio" value="blue">
  <span>Blue</span>
</label>

Non-block form

If you want more control over the DOM, the non-block form only emits a single input element

{{radio-button
    value="green"
    groupValue=color
    name="colors"
    changed="colorChanged"}}

/* results in */
<input id="ember345" class="ember-view" type="radio" value="green">
