Extending an existing jQuery function

I am trying to write a plugin that will extend an existing function in jQuery, eg

(function($)
{
    $.fn.css = function()
    {
        // stuff I will be extending
        // that doesn't affect/change
        // the way .css() works
    };
})(jQuery);

There are only a few bits I need to extend of the .css() function. Mind me for asking, I was thinking about PHP classes since you can className extend existingClass , so I'm asking if it's possible to extend jQuery functions.

当然...只需保存对现有函数的引用，然后调用它：

(function($)
{
    // maintain a reference to the existing function
    var oldcss = $.fn.css;
    // ...before overwriting the jQuery extension point
    $.fn.css = function()
    {
        // original behavior - use function.apply to preserve context
        var ret = oldcss.apply(this, arguments);

        // stuff I will be extending
        // that doesn't affect/change
        // the way .css() works

        // preserve return value (probably the jQuery object...)
        return ret;
    };
})(jQuery);
