Agreed Nikha. Valid point. See i tested by added one line in my code : var users = document.getElementById('users').value; var queryString = "?users=" + users ; * document.write(users); * ajaxRequest.open("GET","ajaxex.php?q="+users,true); ajaxRequest.send(); When i run it , it gives me exact value of the user which i chooses. If my user variable is empty then my output should be blank. Also, http:///db11.app.com/project/ajaxex.php?q=133 It the end of the above link , you can see the exact value of user.
