 queryStirngValue = document.referrer.split("myQuryString")[1].split("%")[1].split("253D")[1];
    alert(queryStirngValue);

    Seems look like you having blank value in string and you are trying to perform split operation. can you check what you get in document.referrer? Commented Oct 13, 2015 at 5:03

 document.referrer.split("myQuryString")[1].split("%")

You first split on myQuryString (which by itself is misspelled?)

With [1] you then want the second array value (because arrays start at 0)

So if myQuryString is not in the QueryString you now have a null value

So

null.split("%")

causes: Uncaught TypeError: Cannot read property 'split' of undefined(…)
