Any page can be presented as a modal dialog by adding the
data-rel="dialog" attribute to the page anchor link. When the "dialog" attribute is applied, the framework adds styles to add rounded corners, margins around the page and a dark background to make the "dialog" appear to be suspended above the page.
<a href="foo.html" data-rel="dialog">Open dialog</a>
By default, the dialog will open with a 'pop' transition. Like all pages, you can specify any page transition you want on the dialog by adding the
data-transition attribute to the link. To make it feel more dialog-like, we recommend specifying a transition of "pop", "slideup" or "flip".
<a href="foo.html" data-rel="dialog" data-transition="pop">Open dialog</a>
When any link is clicked within in a dialog, the framework will automatically close the dialog and transition to the requested page, just as if the dialog were a normal page. To create a "cancel" button in a dialog, just link to the page that triggered the dialog to open and add the
data-rel="back" attribute to your link. This pattern of linking to the previous page is also usable in non-JS devices as well.
data-rel="back" attribute. You can also call the dialog's
close() method to programmatically close dialogs, for example:
Just like the page plugin, you can set a dialog's close button text through option or data attribute. The option can be configured for all dialogs by binding to the
mobileinit event and setting the
$.mobile.dialog.prototype.options.closeBtnText property to a string of your choosing, or you can place the data attribute
data-close-btn-text to configure the text from your markup.
Since dialogs are typically used to support actions within a page, the framework does not include dialogs in the hash state history tracking. This means that dialogs will not appear in your browsing history chronology when the Back button is clicked. For example, if you are on a page, click a link to open a dialog, close the dialog, then navigate to another page, if you were to click the browser's Back button at that point you will navigate back to the first page, not the dialog.
Dialogs can be styled with different themes, just like any page. Here is a different dialog design:An alternate color scheme
