Ie8 支持 function.bind () 方法
<script type = "text/javascript"> if (! function.prototype.bind) {function.prototype.bind = function (othis) {if (typeof this! == "function") {tiro o novo typeError ("function.protype.bind - o que está tentando ser ligado não é chamado"); } var aargs = array.prototype.slice.call (argumentos, 1), ftobind = this, fnop = function () {}, fbound = function () {return ftobind.apply (itens fnop && othis? }; fnop.prototype = this.prototype; fbound.prototype = new FNOP (); retornar fbound; }; } </script>主要解决 “百度地图” 官网上的例子的 Bug ， 摘取如下代码:
