IE8支持function.bind()方法
<script type="text/javascript"> if (!Function.prototype.bind) { Function.prototype.bind = function (oThis) { if (typeof this !== "function") { throw new TypeError("Function.prototype.bind - what is trying to be bound is not callable"); } var aArgs = Array.prototype.slice.call(arguments, 1), fToBind = this, fNOP = function () {}, fBound = function () { return fToBind.apply(this instanceof fNOP && oThis ? this : oThis, aArgs.concat(Array.prototype.slice.call(arguments))); }; fNOP.prototype = this.prototype; fBound.prototype = new fNOP(); return fBound; }; } </script>主要解決“百度地圖”官網上的例子的bug，摘取如下代碼：
