HEX to RGB Converter

Question

I have the JavaScript for converting a HEX value to RGB but I was wondering if I could use jQuery to call the function and insert the HTML?

Here\'s the JavaScript;

Answer 1

valid hex colors can have 3 or 6 characters after the '#'

function hexToRgb(hex){
    if(/^#([a-f0-9]{3}){1,2}$/.test(hex)){
        if(hex.length== 4){
            hex= '#'+[hex[1], hex[1], hex[2], hex[2], hex[3], hex[3]].join('');
        }
        var c= '0x'+hex.substring(1);
        return 'rgb('+[(c>>16)&255, (c>>8)&255, c&255].join(',')+')';
    }
}
