JavaScript中获得URL请求参数

<mce:script type="text/javascript"><!-- function URL(url) { url = url || "http://blog.csdn.net/xxd851116"; this.url = url.toString() ; } URL.prototype.getValue = function(key) { if (this.url == null) return; if (key == null) return; var key_values = this.url.split("?")[1].split("&"); for (var i = 0; i < key_values.length ; i++ ) { var key_value = key_values[i].split("="); if (key == key_value[0]) { return key_value[1]; } } } var url = "http://www.google.cn/search?hl=zh-CN&newwindow=1&q=%E7%AC%91%E7%9A%84%E8%87%AA%E7%84%B6&meta=&aq=f&oq=" ; var url = new URL(url); document.writeln("hl = " + url.getValue("hl") + ";<br/>"); document.writeln("q = " + url.getValue("q") + ";<br/>"); // --></mce:script>

 

测试结果：

hl = zh-CN;
q = %E7%AC%91%E7%9A%84%E8%87%AA%E7%84%B6;
