如果你的浏览器尚不支持这个方法，那么你可以给他补上JavaScript code
1 if (typeof Array.prototype.filter != "function") {
2 Array.prototype.filter = function (fn, context) {
3 var arr = [];
4 if (typeof fn === "function") {
5 for (var k = 0, length = this.length; k < length; k++) {
6 fn.call(context, this[k], k, this) && arr.push(this[k]);
7 }
8 }
9 return arr;
10 };
11 }
