复制代码 代码如下:
String.prototype.getParameter = function (key) {
var re = new RegExp(key + '=([^&]*)(?:&)?');
return this.match(re) && this.match(re)[1];
};
测试代码：
复制代码 代码如下:
<script type="text/javascript"> <br><!-- <br>String.prototype.getParameter = function (key) { <br>var re = new RegExp(key + '=([^&]*)(?:&)?'); <br>return this.match(re) && this.match(re)[1]; <br>}; <br>var s = "http://www.baidu.com/index.html?x0=0&x1=1&x2=2&x3=3&x4=http://www.google.com"; <br>document.write(s.getParameter('x0') + "<br/>"); <br>document.write(s.getParameter('x1') + "<br/>"); <br>document.write(s.getParameter('x2') + "<br/>"); <br>document.write(s.getParameter('x3') + "<br/>"); <br>document.write(s.getParameter('x4') + "<br/>"); <br>document.write(s.getParameter('undefined') + "<br/>"); <br>//--> <br></script>
