jquery: Load CSS values for a class from the css file

I'm look for a way to search a .css style sheet for a class. The particular class would not have been assigned to any particular DOM element as of yet, it is simple in the style sheet.

I saw another thread which said I could use document.styleSheet, but this requires me to know which order the css file is loaded by the document and also which number the class is defined in the style sheet.

I'm just looking for something like:

var $cssClassHeight = $(document).loadCSS('myCl开发者_如何转开发ass', 'height');
var $cssClassWidth = $(document).loadCSS('myClass', 'width');

Anything out there like this, or am I going to have to assign it to a dummy div and then read it from it's attributes?

Thanks

This jQuery plugin allows you to change the properties of a CSS class, so maybe you could alter it to query them instead.
