js获取get参数

譬如url为

http://ttweb.xxxx.com/finance/index.php?r=index/index#report/channelMonthly&cid=17&startT=1509494400&osType=1

 需要获取？后面的所有参数，代码如下:

 

  function getQueryVariable()
    {
        var query = window.document.location.href.toString();  //http://ttweb.xxxx.com/finance/index.php?r=index/index#report/channelMonthly&cid=17&startT=1509494400&osType=1


        var query = query.split("?");  //问号分割网址 ['http://ttweb.xxxx.com/finance/index.php',' r=index/index#report/channelMonthly&cid=17&startT=1509494400&osType=1']
        var vars = query[1].split("&"); //数组索引为1的值（r=index/index#report/channelMonthly&cid=17&startT=1509494400&osType=1）以 & 分割，分割结果为 （ ["r=index/index#report/channelMonthly", "cid=17", "startT=1509494400", "osType=1"]）

        var res = [];
        for (var i=0;i<vars.length;i++) {
            var pair = vars[i].split("=");
            res[pair[0]] = pair[1];
        }
        return res;
    }

    console.log(getQueryVariable())
