I know this is an old question that I came across. In any case, my answer may help another when the same problem arises. Unfortunately, I have no reputation to comment on Trott's answer above.
At the same time, if you use jQuery 1.8 or any $(window).on('load', function() {... }); version after it, then use $(window).on('load', function() {... }); , $(window).load() deprecated in jQuery version 1.8 and there will be a jquery url.indexOf is not a function error. jquery url.indexOf is not a function (at least in jQuery 3.4.1)
