JavaScript如何获取十六进制颜色值而不是RGB值?

使用以下jQuery将获取元素背景色的RGB值:

$('#selector').css('backgroundColor');

有没有办法获取十六进制值而不是RGB?

回答:

var hexDigits = new Array

("0","1","2","3","4","5","6","7","8","9","a","b","c","d","e","f");

//Function to convert rgb color to hex format

function rgb2hex(rgb) {

rgb = rgb.match(/^rgb\((\d+),\s*(\d+),\s*(\d+)\)$/);

return "#" + hex(rgb[1]) + hex(rgb[2]) + hex(rgb[3]);

}

function hex(x) {

return isNaN(x) ? "00" : hexDigits[(x - x % 16) / 16] + hexDigits[x % 16];

}
