js实现String.Fomat的实例代码

String.Format = function (str) {  for (var i = 1; i < arguments.length; i++) {    var parent = "//{" + (i - 1) + "//}";    var reg = new RegExp(parent, "g")    str = str.replace(reg, arguments[i]);  }  return str;}

string.Format("<span>您的答案是：<b>{0}</b></span>", remark);

str += string.Format(temp, data[i].Item2, data[i].Item1);
