Parse query string in JavaScript [duplicate]

Answer 1

I wanted to pick up specific links within a DOM element on a page, send those users to a redirect page on a timer and then pass them onto the original clicked URL. This is how I did it using regular javascript incorporating one of the methods above.

Page with links: Head

  function replaceLinks() {   
var content = document.getElementById('mainContent');
            var nodes = content.getElementsByTagName('a');
        for (var i = 0; i < document.getElementsByTagName('a').length; i++) {
            {
                href = nodes[i].href;
                if (href.indexOf("thisurl.com") != -1) {

                    nodes[i].href="http://www.thisurl.com/redirect.aspx" + "?url=" + nodes[i];
                    nodes[i].target="_blank";

                }
            }
    }
}

Body

Redirect page Head

   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 (decodeURIComponent(pair[0]) == variable) {
                return decodeURIComponent(pair[1]);
            }
        }
        console.log('Query variable %s not found', variable);
    }
    function delayer(){
        window.location = getQueryVariable('url')
    }
