JavaScript中獲得URL請求參數

<mce:script type="text/javascript"><!--<br />function URL(url) {<br />url = url || "http://blog.csdn.net/xxd851116";<br />this.url = url.toString() ;<br />}</p><p>URL.prototype.getValue = function(key) {<br />if (this.url == null) return;<br />if (key == null) return;<br />var key_values = this.url.split("?")[1].split("&");<br />for (var i = 0; i < key_values.length ; i++ )<br />{<br />var key_value = key_values[i].split("=");<br />if (key == key_value[0])<br />{<br />return key_value[1];<br />}<br />}<br />}</p><p>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=" ;<br />var url = new URL(url);<br />document.writeln("hl = " + url.getValue("hl") + ";<br/>");<br />document.writeln("q = " + url.getValue("q") + ";<br/>");<br />// --></mce:script>

 

測試結果：

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