javacriptreplace正则取字符串中的值并替换【推荐】

function doSubmit(){
  var cOntent= UE.getEditor('messageTemplate').getContent(); 
  cOntent= content.replace(/rgba&＃63;\(\s&＃63;\d+\s&＃63;,\s&＃63;\d+\s&＃63;,\s&＃63;\d+\s&＃63;\)/g,function(){
    return fixColor('color',arguments[0]);
  })
  .......
}
 //rgb颜色 转16进制
function fixColor(name,value){
  if (/color/i.test(name) && /rgba&＃63;/.test(value)) {
    console.log(value);
    var array = value.split(",");
    if (array.length > 3){
      return "";
    }
    value = "#";
    for (var i = 0, color; color = array[i++];) {
      color = parseInt(color.replace(/[^\d]/gi, ''), 10).toString(16);
      value += color.length == 1 &＃63; "0" + color : color;
    }
    value = value.toUpperCase();
  }
  return value;
}

function test(){
  var str = "";//目标替换成 
  str = str.replace(/ color_tag=\"(#.{6})\"/g,function(){
    return "="+arguments[1];
  })
  console.log(str);
}
