I tried it myself and it works great
function zero_fill_hex(num, digits) {
var s = num.toString(16);
while (s.length < digits)
s = "0" + s;
return s;
}
function rgb2hex(rgb) {
if (rgb.charAt(0) == '#')
return rgb;
var ds = rgb.split(/\D+/);
var decimal = Number(ds[1]) * 65536 + Number(ds[2]) * 256 + Number(ds[3]);
return "#" + zero_fill_hex(decimal, 6);
}
The above is the entire content of this article, I hope you all like it.
