Obtain parameters in url through regular expressions (graphic tutorial)

Below I will bring you a simple implementation of obtaining parameters in the url through regular expressions. Let me share it with you now and give it as a reference for everyone.

url：

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

js中：

var name = getUrlParam("name");
/*通过正则获取url中的参数*/
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;
}

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
