Usage

You can use the listener wherever you are triggering a display of anything (menu, modal, etc.) and need the ability to close it via clicking outside of the specified element.

If you are using Ember Composable Helpers and the entire parent component is the allowable click area, you can pass in the a concatenated string of the ID selector # and elementId as the parentSelector:

// template.hbs

{{#if menuToggled}}
  {{ember-dom-click-listener
    fireAction=(action 'closeMenu')
    parentSelector=(concat '#' elementId)
  }}
{{/if}}

Otherwise you can pass in a string as the parentSelector:

// template.hbs

{{#if menuToggled}}
  {{ember-dom-click-listener
    fireAction=(action 'closeMenu')
    parentSelector='.my-selector'
  }}
{{/if}}

You can also pass in an array of selector strings allowedSelectors if you need to specify more allowable click areas:

// template.hbs

{{#if menuToggled}}
  {{ember-dom-click-listener
    fireAction=(action 'closeMenu')
    allowedSelectors=myListOfSelectors
    parentSelector='.my-selector'
  }}
{{/if}}

// parent component or controller

export default Component.extend({

  myListOfSelectors: computed(function() {
    return ['.another-selector', '.yet-another-selector'];
  })

});

Again, if you're using Ember Composable Helpers you can concatenate your own array via the array helper:

// template.hbs

{{#if menuToggled}}
  {{ember-dom-click-listener
    fireAction=(action 'closeMenu')
    allowedSelectors=(array '#selector-1' '.selector-2' '.selector-3')
    parentSelector='.my-selector'
  }}
{{/if}}

As for the action, it can be defined in the parent component or passed in as a closure:

// parent component or controller

actions: {
  closeMenu() {
    this.toggleProperty('menuToggled');
  }
}
