## How it works

The confirm module is automatically invoked on page load, you just need to add some specific data attributes

to the element that will trigger the confirmation modal.

## Source files

* `lib/amd/src/utility.js` ({{< jsdoc module="core/utility" >}})

* `lib/templates/modal.mustache`

## Usage

The confirmation AMD module is loaded automatically, so the only thing you need to do is to add some specific data attributes

to the target element:

{{< highlight html >}}

<button type="button" class="btn btn-primary" data-confirmation="modal" data-confirmation-title-str='["delete", "core"]'

data-confirmation-content-str='["areyousure"]' data-confirmation-yes-button-str='["delete", "core"]'>Show confirmation modal</button>

{{< /highlight >}}

You can also use it on PHP, you just need to set the attributes parameter to any moodle output component that takes attributes:

{{< php >}}

echo $OUTPUT->single_button('#', get_string('delete'), 'get', [

    'data-confirmation' => 'modal',

    'data-confirmation-title-str' => json_encode(['delete', 'core']),

    'data-confirmation-content-str' => json_encode(['areyousure']),

    'data-confirmation-yes-button-str' => json_encode(['delete', 'core'])

]);

{{< / php >}}

## Attributes

<table class="table">

  <thead>

    <tr>

      <th style="width: 250px;">Data attribute</th>

      <th>Description</th>

    </tr>

  </thead>

  <tbody>

    <tr>

      <td>data-confirmation</td>

      <td>The identifier value must be "modal" so the module can find and register an event listener for that element.</td>

    </tr>

    <tr>

      <td>data-confirmation-title-str</td>

      <td>The modal title language string identifier, must be provided in JSON encoded format.</td>

    </tr>

    <tr>

      <td>data-confirmation-content-str</td>

      <td>The modal main content language string identifier, must be provided in JSON encoded format.</td>

    </tr>

    <tr>

      <td>data-confirmation-yes-button-str</td>

      <td>The language string identifier for the "Yes" button, must be provided in JSON encoded format.</td>

    </tr>

    <tr>

      <td>data-confirmation-toast</td>

      <td>If set to "true" it will display a confirmation toast in the end.</td>

    </tr>

    <tr>

      <td>data-confirmation-toast-confirmation-str</td>

      <td>The confirmation toast language string identifier, must be provided in JSON encoded format.</td>

    </tr>

    <tr>

      <td>data-confirmation-destination</td>

      <td>An url to redirect the user to.</td>

    </tr>

  </tbody>

</table>
