can i force jquery cssbackgroundcolor returns on hexadecimal format

can i force jquery cssbackgroundcolor returns on hexadecimal format  using -'jquery,rgb,hex,background-color'

I have an element like this:

<p>My text with a <strong class="highlighted">sample highlight</strong>.<p>

And the CSS class like this:

.highlighted {
    background: #f0ff05;
    font-weight: normal;

But when I use a jQuery like this:


It returns rgb(240, 255, 5). I could write some function to convert from rgb to hex, but I would like to know if there is some way to jQuery return the value already on hexadecimal format.

Colors are always returned as rgb (except IE6 which already returns in hex), then we cannot return in another format natively.

Like you said, you can write a function to convert hex to rgb. Here is a topic with several examples of how to write this function: Get hex value rather than RGB value using jQuery.

But you wonder if there is a way to directly return the jQuery already in hex: the answer is yes, this is possible using CSS Hooks since jQuery 1.4.3.

The code should be:

$.cssHooks.backgroundColor = {
    get: function(elem) {
        if (elem.currentStyle)
            var bg = elem.currentStyle["backgroundColor"];
        else if (window.getComputedStyle)
            var bg = document.defaultView.getComputedStyle(elem,
        if ("rgb") == -1)
            return bg;
        else {
            bg = bg.match(/^rgb\((\d+),\s*(\d+),\s*(\d+)\)$/);
            function hex(x) {
                return ("0" + parseInt(x).toString(16)).slice(-2);
            return "#" + hex(bg[1]) + hex(bg[2]) + hex(bg[3]);

And when you call $(".highlighted").css("backgroundColor"), the return will be #f0ff05. Here is a working sample to you see it working.
