How to get url parameters through JS function

//通过以下JS函数获取url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);
}

for example:

url example: http://www.baidu.com/index.html?id=1024&name=lianxingjie

Calling getQueryVariable("id") returns 1024.

Calling getQueryVariable("name") returns "lianxingjie".

Calling getQueryVariable("sex") returns false.
