<span class="text">Explanation</span>
|
|
</h2>
|
|
<p>The component embedded inside the modal is always rendered when
|
|
the live view is mounted but is kept hidden until <code class="inline">Modal.JS.open</code>
|
|
is called on it. On subsequent openings within the same session
|
|
the contents of the modal are completely remounted. This assures
|
|
that any stateful components inside the modal are reset to their
|
|
initial state.</p><p><code class="inline">Modal</code> exposes two functions for managing window state:</p><ul><li><p><code class="inline">Modal.JS.open/1</code> - to open the modal from the frontend. It's
|
|
important to make sure the element triggering that call is
|
|
wrapped in an Alpine UI component - or is an Alpine component
|
|
itself - adding <code class="inline">x-data</code> attribute without any value is enough
|
|
to ensure that.</p></li><li><p><code class="inline">Modal.close/2</code> - to close the modal from the backend; usually
|
|
done inside wrapped component's <code class="inline">handle_event/2</code>. The example
|
|
quoted above shows one way to implement this, under that assumption
|
|
that the component exposes a callback, like this:</p><pre><code class="makeup elixir" translate="no"><span class="kd">defmodule</span><span class="w"> </span><span class="nc">SomeForm</span><span class="w"> </span><span class="k" data-group-id="7964257868-1">do</span><span class="w">
