js获取url中携带的参数

function getQueryVariable(variable)
{
       var query = window.location.search.substring(1);
       var vars = query.split("&");
       for (var i=0;i<vars.length;i++) {
               var pair = vars[i].split("=");
               if(pair[0] == variable){return pair[1];}
       }
       return(false);
}

直接至行政函数即可 www.xxx.com?uid=10&did=20

获取
参数要用双引号括起来
var uid = getQueryVariable(“uid”);
