Pages

The page widget is responsible for managing a single item in jQuery Mobile's page-based architecture. It is designed to support either single page widgets within a HTML document, or multiple local internal linked page widgets within a HTML document.

The goal of this model is to allow developers to create websites using best practices — where ordinary links will "just work" without any special configuration — while creating a rich, native-like experience that can't be achieved with standard HTTP requests.

The page widget will auto-enhance its content upon creation. This means that it will instantiate widgets on its child elements by invoking .enhanceWithin() on itself.

Dialogs

The page widget has the option dialog which you can set to true to obtain a page styled like a dialog, such as in the example below: 

<div data-role="page" data-dialog="true">
  <div data-role="header">
    <h2>Are you sure?</h2>
  </div>
  <div class="ui-content" role="main">
    <h2>Are you sure you wish to exit the application?</h2>
    <p>You have unsaved changes. If you exit without saving them, you will lose them.</p>
    <div class="ui-grid-a">
      <div class="ui-block-a">
        <a href="#" id="exit-button" class="ui-btn ui-btn-b ui-shadow ui-corner-all">Exit</a>
      </div>
      <div class="ui-block-b">
        <a href="#" id="cancel-button" class="ui-btn ui-shadow ui-corner-all">Cancel</a>
      </div>
    </div>
  </div>
</div>

You can programmatically close a page styled as a dialog by navigating to another page. For example, you can use the pagecontainer change method: 

$( ":mobile-pagecontainer" ).pagecontainer( "change", "somepage.html" );

You can also simply go back: 

$.mobile.back();

Options

classes

Type: Object
Default: 
{}

Specify additional classes to add to the widget's elements. Any of classes specified in the Theming section can be used as keys to override their value. To learn more about this option, check out the learn article about the classes option.

Code examples:

Initialize the page with the classes option specified, changing the theming for the ui-page class:

$( ".selector" ).page({
  classes: {
    "ui-page": "highlight"
  }
});

Get or set a property of the classes option, after initialization, here reading and changing the theming for the ui-page class:

// Getter
var themeClass = $( ".selector" ).page( "option", "classes.ui-page" );
 
// Setter
$( ".selector" ).page( "option", "classes.ui-page", "highlight" );

closeBtn

Type: String
Default: "left"
This option is provided by the dialog extension.

Sets the position of the dialog close button in the header.

Possible values:

"left"
The button will be placed on the left edge of the titlebar.
"right"
The button will be placed on the right edge of the titlebar.
"none"
The dialog will not have a close button.

This option is also exposed as a data attribute: data-close-btn.

Code examples:

Initialize the page with the closeBtn option specified:

$( ".selector" ).page({
  closeBtn: "none"
});

Get or set the closeBtn option, after initialization:

// Getter
var closeBtn = $( ".selector" ).page( "option", "closeBtn" );
 
// Setter
$( ".selector" ).page( "option", "closeBtn", "none" );

closeBtnText

Type: String
Default: "Close"
This option is provided by the dialog extension.

Customizes the text of the close button which is helpful for translating this into different languages. The close button is displayed as an icon-only button by default so the text isn't visible on-screen, but is read by screen readers so this is an important accessibility feature.

This option is also exposed as a data attribute: data-close-btn-text="Fermer".

Code examples:

Initialize the page with the closeBtnText option specified:

$( ".selector" ).page({
  closeBtnText: "Fermer"
});

Get or set the closeBtnText option, after initialization:

// Getter
var closeBtnText = $( ".selector" ).page( "option", "closeBtnText" );
 
// Setter
$( ".selector" ).page( "option", "closeBtnText", "Fermer" );

contentTheme

Type: String
Default: null, inherited from parent

Note:This option is deprecated in 1.4.0 and will be removed in 1.5.0.

Sets the color scheme (swatch) for the content div of the page widget. It accepts a single letter from a-z that maps to the swatches included in your theme.

Possible values: swatch letter (a-z).

This option is also exposed as a data attribute: data-content-theme="b".

(version deprecated: 1.4.0)
Code examples:

Initialize the page with the contentTheme option specified:

$( ".selector" ).page({
  contentTheme: "b"
});

Get or set the contentTheme option, after initialization:

// Getter
var contentTheme = $( ".selector" ).page( "option", "contentTheme" );
 
// Setter
$( ".selector" ).page( "option", "contentTheme", "b" );

corners

Type: Boolean
Default: true
This option is provided by the dialog extension.

Sets whether to draw the dialog with rounded corners.

This option is also exposed as a data attribute: data-corners="false".

});

Get or set the corners option, after initialization:

// Getter
var corners = $( ".selector" ).page( "option", "corners" );
 
// Setter
$( ".selector" ).page( "option", "corners", false );

defaults

Type: Boolean
Default: false
Seting this option to true indicates that other widgets options have default values and causes jQuery Mobile's widget autoenhancement code to omit the step where it retrieves option values from data attributes. This can improve startup time.

This option is also exposed as a data attribute: data-defaults="true".

Code examples:

Initialize the page with the defaults option specified:

$( ".selector" ).page({
  defaults: true
});

Get or set the defaults option, after initialization:

// Getter
var defaults = $( ".selector" ).page( "option", "defaults" );
 
// Setter
$( ".selector" ).page( "option", "defaults", true );

Note:This option is deprecated as of jQuery Mobile 1.4.0 and will be removed in 1.5.0. Use $.mobile.degradeInputs instead.

(version deprecated: 1.4.0)

// Setter
$( ".selector" ).page( "option", "dialog", true );

disabled

Type: Boolean
Default: false

// Setter
$( ".selector" ).page( "option", "disabled", true );

domCache

Type: Boolean
Default: false

initSelector

Type: Selector
Default: See below

The default initSelector for the page widget is:

":jqmData(role='page')"

Note: This option is deprecated in 1.4.0 and will be removed in 1.5.0.
As of jQuery Mobile 1.4.0, the initSelector is no longer a widget option. Instead, it is declared directly on the widget prototype. Thus, you may specify a custom value by handling the mobileinit event and overwriting the initSelector on the prototype:

$( document ).on( "mobileinit", function() {
  $.mobile.page.prototype.initSelector = "div.custom";
});

Note: Remember to attach the mobileinit handler after you have loaded jQuery, but before you load jQuery Mobile, because the event is triggered as part of jQuery Mobile's loading process.

The value of this option is a jQuery selector string. The framework selects elements based on the value of this option and instantiates page widgets on each of the resulting list of elements.

(version deprecated: 1.4.0)

keepNative

Type: Selector
Default: null

Note:This option is deprecated as of jQuery Mobile 1.4.0 and will be removed in 1.5.0. Use $.mobile.keepNative instead.

The value of this option is a selector that will be used in addition to the keepNativeDefault option to prevent elements matching it from being enhanced.

This option is also exposed as a data attribute: data-keep-native=".do-not-enhance.

(version deprecated: 1.4.0)
Code examples:

Initialize the page with the keepNative option specified:

$( ".selector" ).page({
  keepNative: ".do-not-enhance"
});

Get or set the keepNative option, after initialization:

// Getter
var keepNative = $( ".selector" ).page( "option", "keepNative" );
 
// Setter
$( ".selector" ).page( "option", "keepNative", ".do-not-enhance" );

keepNativeDefault

Type: Selector
Default: ":jqmData(role='none'), :jqmData(role='nojs')"

Note:This option is deprecated as of jQuery Mobile 1.4.0 and will be removed in 1.5.0. Use $.mobile.keepNative instead.

The value of this option is a selector that will be used to prevent elements matching it from being enhanced.

This option is also exposed as a data attribute: data-keep-native-default=".do-not-enhance.

(version deprecated: 1.4.0)

// Setter
$( ".selector" ).page( "option", "keepNativeDefault", ".do-not-enhance" );

overlayTheme

Type: String
Default: "a"
This option is provided by the dialog extension.
