jQuery UI Dialog


A dialog is a floating window that contains a title bar and a content area. The dialog window can be moved, resized and closed with the 'x' icon by default.

If the content length exceeds the maximum height, a scrollbar will automatically appear.

A bottom button bar and semi-transparent modal overlay layer are common options that can be added.

A call to $(foo).dialog() initializes a dialog. If you want a click to open a dialog, use $(foo).dialog('open'), but if the dialog hasn't been destroyed, the $(foo).dialog() init call is only required once, not on each click.

The jQuery UI Dialog plugin uses the jQuery UI CSS Framework to style its look and feel, including colors and background textures. We recommend using the ThemeRoller tool to create and download custom themes that are easy to build and maintain.

If a deeper level of customization is needed, there are widget-specific classes referenced within the ui.dialog.css stylesheet that can be modified. These classes are highlighed in bold below.

Sample markup with jQuery UI CSS Framework classes

<div class="ui-dialog ui-widget ui-widget-content ui-corner-all ui-draggable ui-resizable">
   <div class="ui-dialog-titlebar ui-widget-header ui-corner-all ui-helper-clearfix">
      <span id="ui-dialog-title-dialog" class="ui-dialog-title">Dialog title</span>
      <a class="ui-dialog-titlebar-close ui-corner-all" href="#"><span class="ui-icon ui-icon-closethick">close</span></a>
   <div style="height: 200px; min-height: 109px; width: auto;" class="ui-dialog-content ui-widget-content" id="dialog">
      <p>Dialog content goes here.</p>

Note: This is a sample of markup generated by the dialog plugin, not markup you should use to create a dialog. The only markup needed for that is <div></div>.
