Simple implementation of obtaining parameters in url through regular expressions

url:

http://xxxx.com?name=charm&id=123

In js:

 var name = getUrlParam("name");/*Get parameters in the url through regular operation*/function getUrlParam(name){ var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)"); var r = window.location.search.substr(1).match(reg); if(r!=null)return decodeURI(r[2]); return null;}
