jquery Gets the problem of Background-color color values in the style _jquery

Today, using jquery to get the value of the Background-color in the style, we find that the color value in IE is not the same as that of Chrome and Firefox, ie displays "#ffff00" in the hex format, while Chrome, Firefox is in GRB format display "RGB (255,255,0)", and I need hexadecimal color value, used to store in the database, find the next piece of code on the Internet can solve this problem:

Copy Code code as follows:

$.fn.gethexbackgroundcolor = function () {
var RGB = $ (this). CSS (' Background-color ');
if (!$.browser.msie) {
RGB = Rgb.match (/^rgb\ (\d+), \s* (\d+), \s* (\d+) \) $/);
function Hex (x) {
Return ("0" + parseint (x). toString). Slice (-2);
}
rgb= "#" + Hex (rgb[1]) + hex (rgb[2]) + hex (rgb[3));
}
return RGB;
}

This is all displayed in hex format and has been validated.
