ember-wormhole
Advanced tools
This ember-cli addon provides a component that allows for rendering a block in a typical Ember context in terms of bound data and action handling, but attached to a DOM element somewhere else on the page.
This library is particularly useful for cases where you have UI that is the logical child of a component but needs to render as a top-level DOM element, such as a confirmation dialog.
This component takes advantage of a private API of HTMLBars (we're hoping to craft a public
API so we can be confident this library will continue to work in future versions of
Ember). An Ember Component has a _morph property which its children are attached to.
In a typical component, _morph is the component's element, a div by default.
ember-wormhole sets the component's _morph to an element that you point it at. As a
result, the component's children are attached to that element in the DOM. That includes
usages of yield, so blocks provided to ember-wormhole appear in another part of
the DOM. Nothing else changes -- data binding and action bubbling still flow according
to the Ember component hierarchy.
We thought you'd never ask...
Given the following DOM:
<body class="ember-application">
<div id="destination">
</div>
<div class="ember-view">
<!-- rest of your Ember app's DOM... -->
</div>
</body>
and a template like this:
{{#ember-wormhole to="destination"}}
Hello world!
{{/ember-wormhole}}
Then "Hello world!" would be rendered inside the destination div.
If the ember-wormhole is destroyed it's far-off children are destroyed too. For example, given:
{{#if isWormholeEnabled}}
{{#ember-wormhole to="destination"}}
Hello world!
{{/ember-wormhole}}
{{/if}}
If isWormholeEnabled starts off true and becomes false, then the "Hello
world!" text will be removed from the destination div.
Similarly, if you use ember-wormhole in a route's template, it will
render its children in the destination element when the route is entered
and remove them when the route is exited.
