function getUrl(name="") { var url = location.search; //获取url中"?"符后的字串 var theRequest = new Object(); if (url.indexOf("?") != -1) { var str = url.substr(1); strs = str.split("&"); for(var i = 0; i < strs.length; i ++) { theRequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]); } } if(name == ""){ return theRequest; }else{ return theRequest[name]?theRequest[name]:''; } }
用法:getUrl("id");
注意
1.不传入值则返回地址的所有参数
2.若没有找到匹配的参数则返回一个空的JSON
