问题:

I'm looking to style a modal dialog (using UI Dialog) with unique CSS that is separate from the traditional dialog, so in essence to have two jQuery dialogs that each look different.

I've styled one, for example,

<div id="dialog_style1" class="dialog1 hidden">One content</div>

and another

<div id="dialog_style2" class="dialog2 hidden">Another content</div>

Unfortunately I've noticed that using separate CSS to style parts of the dialog box, like

.dialog1 .ui-dialog-titlebar { display:none; }
.dialog2 .ui-dialog-titlebar { color:#aaa; }

doesn't work because .ui-dialog-titlebar does not have the class .dialog1, and I can't do an addClass either without breaking into the plugin.

An alternative would be to have an element like body have a unique class/id (depending on which one I want), but that would preclude having both dialogs in the same page.

How can I do this?

回答1:

The current version of dialog has the option "dialogClass" which you can use with your id's. For example,

$('foo').dialog({dialogClass:'dialog_style1'});

Then the CSS would be

.dialog_style1 {color:#aaa;}

回答2:

Run the following immediately after the dialog is called in the Ajax:

    $(".ui-dialog-titlebar").hide();
    $(".ui-dialog").addClass("customclass");

This applies just to the dialog that is opened, so it can be changed for each one used.

(This quick answer is based on another response on Stack Overflow.)

This issue turned up for me when I was trying to find a similar answer. Consider:

    $('.ui-dialog').wrap('<div class="abc" />');
    $('.ui-widget-overlay').wrap('<div class="abc" />');

Where abc is the name of your 'CSS wrapper' - see Stack Overflow question Custom CSS scope and jQuery UI dialog themes where I found the answer from Evgeni Nabokov. For more information on the CSS wrapper in use with a jQuery UI dialog box - see the following (but note they do NOT really solve the issue of the CSS wrapper with the dialog box - you need the above comments to help there, Using Multiple jQuery UI Themes on a Single Page (Filament blog).

According to the UI dialog documentation, the dialog plugin generates something like this:

<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>
   <div class="ui-dialog-content ui-widget-content" id="dialog_style1">
      <p>One content</p>
   </div>
</div>

That means what you can add to any class to exactly to first or second dialog using jQuery's closest() method. For example:

$('#dialog_style1').closest('.ui-dialog').addClass('dialog_style1');

$('#dialog_style2').closest('.ui-dialog').addClass('dialog_style2');

and then CSS it.

I created custom styles by just overriding jQuery classes in inline style. So on top of the page, you have the jQuery CSS linked and right after that override the classes you need to modify:

<head>
    <link href="/Content/theme/base/jquery.ui.all.css" rel="stylesheet"/>

    <style type="text/css">
        .ui-dialog .ui-dialog-content
        {
            position: relative;
            border: 0;
            padding: .5em 1em;
            background: none;
            overflow: auto;
            zoom: 1;
            background-color: #ffd;
            border: solid 1px #ea7;
        }

        .ui-dialog .ui-dialog-titlebar
        {
            display:none;
        }

        .ui-widget-content
        {
            border:none;
        }
    </style>
</head>

The standard way to do this is with jQuery UI's CSS Scopes:

<div class="myCssScope">
   <!-- dialog goes here -->
</div>

Unfortunately, the jQuery UI dialog moves the dialog DOM elements to the end of the document, to fix potential z-index issues. This means the scoping won't work (it will no longer have a ".myCssScope" ancestor).

Christoph Herold designed a workaround which I've implemented as a jQuery plugin, maybe that will help.

回答7:

You can add the class to the title like this:

$('#dialog_style1').siblings('div.ui-dialog-titlebar').addClass('dialog1');

回答8:

Try these:

#dialog_style1 .ui-dialog-titlebar { display:none; }
#dialog_style2 .ui-dialog-titlebar { color:#aaa; }

The best recommendation I can give for you is to load the page in Firefox, open the dialog and inspect it with Firebug, then try different selectors in the console, and see what works. You may need to use some of the other descendant selectors.
