• javascript
• ruby-on-rails

• which library is it? – hjpotter92 Commented Jul 11, 2016 at 12:05
• Do you have such plugin included in page? $.url is not a jQuery core method – charlietfl Commented Jul 11, 2016 at 12:09

$.url() 

is not part of the jQuery Core. If you want to achieve something similiar, maybe use

var getUrlParameter = function getUrlParameter(sParam) {
    var sPageURL = decodeURIComponent(window.location.search.substring(1)),
        sURLVariables = sPageURL.split('&'),
        sParameterName,
        i;

    for (i = 0; i < sURLVariables.length; i++) {
        sParameterName = sURLVariables[i].split('=');

        if (sParameterName[0] === sParam) {
            return sParameterName[1] === undefined ? true : sParameterName[1];
        }
    }
};

to use it:

var tech = getUrlParameter('technology');

In your example it would something like this

if(getUrlParameter('ig') == 'true') {

source

//Just use this, no need to do loops:
    var getUrlParameter = function getUrlParameter(sParam) {
        var r = "";

        if (window.locaton.href.substring(window.locaton.href.indexOf(sParam + "="))) {
            r = window.locaton.href.substring(window.locaton.href.indexOf(sParam + "=")(sParam + "=").length + 1);
            // trim if there is other parameter on the list
            if (r.indexOf("&") > 0)
                r = r.substring(0, r.indexOf("&"));
        }
        // please do some simple test, I just wrote it without testing the code
        return r;
    }

Your code might be assuming that the library purl library, https://github./allmarkedup/purl, is loaded but isn't or is inaccessible.

You might try the alternate approach:

if(purl().param('ig') == 'true') {
