- 本文列举了用javascript获取地址栏参数的三种方法:
- 方法一:
- <script type="text/javascript">
- <!--
- String.prototype.getQuery = function(name) {
- var reg = new RegExp("(^&)"+ name +"=([^&]*)(&$)");
- var r = this.substr(this.indexOf("\?")+1).match(reg);
- if (r!=null) return unescape(r[2]); return null;
- }
- var strHref = www.taomoban.net/index.htm?a=aaa&b=bbb&c=ccc;
- alert(strHref.getQuery("a"));
- alert(strHref.getQuery("b"));
- alert(strHref.getQuery("c"));
- //-->
- </script>
- 方法二:
- <script type="text/javascript">
- function getUrlPara(paraName){
- var sUrl = location.href;
- var sReg = "(?:\\?&){1}"+paraName+"=([^&]*)"
- var re=new RegExp(sReg,"gi");
- re.exec(sUrl);
- return RegExp.$1;
- }
- //应用实例:test_para.html?a=11&b=22&c=33
- alert(getUrlPara("a"));
- alert(getUrlPara("b"));
- </script>
- 方法三:
- <script type="text/javascript">
- <!--
- function Request(strName){
- var strHref = "www.taomoban.net/index.htm?a=aaa&b=bbb&c=ccc";
- var intPos = strHref.indexOf("?");
- var strRight = strHref.substr(intPos + 1);
- var arrTmp = strRight.split("&");
- for(var i = 0; i < arrTmp.length; i++) {
- var arrTemp = arrTmp[i].split("=");
- if(arrTemp[0].toUpperCase() == strName.toUpperCase()) return arrTemp[1];
- }
- return "";
- }
- alert(Request("a"));
- alert(Request("b"));
- alert(Request("c"));
- //-->
- </script>
