RGB转HEX

方法如下所示：

colorHex: function (string) {if (/^(rgb|RGB)/.test(string)) {var aColor = string.replace(/(?:\(|\)|rgb|RGB)*/g, "").split(",");var strHex = "#";for (var i = 0; i < aColor.length; i++) {var hex = Number(aColor[i]).toString(16);// 修正：不足两位，补0if (hex.length == 1) {hex = "0" + hex} else {if (hex == "0") {hex += hex;}}strHex += hex;}console.log("rgb:" + strHex);if (strHex.length != 7) {strHex = string;}return strHex;} else if (reg.test(string)) {var aNum = string.replace(/#/, "").split("");if (aNum.length === 6) {return string;} else if (aNum.length === 3) {var numHex = "#";for (var i = 0; i < aNum.length; i += 1) {numHex += (aNum[i] + aNum[i]);}return numHex;}} else {return string;}}
