例如一个url 为 http://www.runoob.com/index.php?id=1&image=awesome.jpg ，问号后面为 url 参数，其中多个参数时候会使用 & 符号

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);
}
getQueryVariable("id")
