| 5 | <p>The Material Design Lite (MDL) <strong>dialog</strong> component allows for verification of |
| 6 | user actions, simple data input, and alerts to provide extra information to users.</p> |
| 7 | <h2 id="basic-usage">Basic Usage</h2> |
| 8 | <p>To use the dialog component, you must be using a browser that supports the <a href="http://www.w3.org/TR/2013/CR-html5-20130806/interactive-elements.html#the-dialog-element">dialog element</a>. |
| 9 | Only Chrome and Opera have native support at the time of writing. |
| 10 | For other browsers you will need to include the <a href="https://github.com/GoogleChrome/dialog-polyfill">dialog polyfill</a> or create your own.</p> |
| 11 | <p>Once you have dialog support create a dialog element. |
| 12 | The element when using the polyfill <strong>must</strong> be a child of the <code>body</code> element. |
| 13 | Within that container, add a content element with the class <code>mdl-dialog__content</code>. |
| 14 | Add you content, then create an action container with the class <code>mdl-dialog__actions</code>. |
| 15 | Finally for the markup, add your buttons within this container for triggering dialog functions.</p> |
| 16 | <p>Keep in mind, the order is automatically reversed for actions. |
| 17 | Material Design requires that the primary (confirmation) action be displayed last. |
| 18 | So, the first action you create will appear last on the action bar. |
| 19 | This allows for more natural coding and tab ordering while following the specification.</p> |
| 20 | <p>Remember to add the event handlers for your action items. |
| 21 | After your dialog markup is created, add the event listeners to the page to trigger the dialog to show.</p> |
| 22 | <p>For example:</p> |
| 23 | <pre><code class="lang-javascript"> var button = document.querySelector('button'); |
| 24 | var dialog = document.querySelector('dialog'); |
| 25 | button.addEventListener('click', function() { |
| 26 | dialog.showModal(); |
| 27 | /* Or dialog.show(); to show the dialog without a backdrop. */ |
| 28 | }); |
| 29 | </code></pre> |
