To Get the query string value from Javascript

Question

I have a code but it is not running properly.

function QueryStringParam1(d) {
        var vars = [], hash;
        var q = document.URL.split('?')[0];   
        if (q != undefined) {
            q = q.split('&');
            for (var i = 0; i < q.length; i++) {
                hash = q[i].split('=');
                vars.push(hash[1]);
                vars[hash[0]] = hash[1];
            }
        }
        return vars[d];
    }

should be `var q = document.URL.split('?')[1]` if you want the query string — Oliboy50, Jan 29 '14 at 13:29
`document` object hasn't `URL` property. You have to use `location.href` instead — hindmost, Jan 29 '14 at 13:32

Most likely you are trying to get query string value from this query. So you would be getting string having its value after '?' char.

So after split relevant string should be in 1 index not 0.. replace

var q = document.URL.split('?')[0];

by

var q = document.URL.split('?')[1];
