如何让jQueryUI的'对话'小部件使用`ui-state-error`样式？

Question

I'm using one of the standard themes (redmond) provided on the jQuery UI website.

I noticed that it ships with an icon png file with red icons as well as the blue coloured ones. I need to display a warning dialog box but make it use the red icons instead.

I notice in the theme's stylesheet there's a section called "Interaction Cues". Do I just set my dialogClass to ui-state-error which seems to have the desired effect, is this the correct way to do this?

I tried setting dialogClass: "error" but that had no effect.

Yep you have it right, you need the full class name:

$("div").dialog({ dialogClass: "ui-state-error" });

You can test it out here .
