js javaScript中String添加replaceAll 方法

String.prototype.replaceAll = function(s1, s2) { return this.replace(new RegExp(s1, "gm"), s2); //g全局 } String.prototype.replaceAll2Excep = function(s1, s2) { var temp = this; while (temp.indexOf(s1) != -1) { temp = temp.replace(s1, s2); } return temp; } alert("abcedaaabs".replaceAll("a", "A")); alert("abcedaaabs".replaceAll2Excep ("a", "A"));
