jquery＃color to rgba？ [英] jquery # colour to rgba?

问题描述

是否可以将＃ff0000 转换为rgb？

Is it possible to convert a colour as such #ff0000 to rgb?

$ c>＃ff0000 至 rgb（255,0,0）;

So convert #ff0000 to rgb(255,0,0);

我很确定这必须是可能的，我只是不知道如何。

I'm pretty sure this has got to be possible, I just don't know how. Any insight would be great!

推荐答案

您可以使用：

var s = "#ff0000";
var patt = /^#([\da-fA-F]{2})([\da-fA-F]{2})([\da-fA-F]{2})$/;
var matches = patt.exec(s);
var rgb = "rgb("+parseInt(matches[1], 16)+","+parseInt(matches[2], 16)+","+parseInt(matches[3], 16)+");";
alert(rgb);
