Hi All, I have a js code:

    window.onload = function() {
        document.getElementById("Button1").onclick = function() {
            var t1 = document.getElementById("Text1").value;
            var t2 = document.getElementById("Text2").value;

            document.URL = 'myurl?t1=' + t1 + '&t2' + t2;
         }
    }

Here i am adding t1,t2 as query param..now my question is lets say i have entered some data in Textbox1 but not in textbox2, in that case the url I am getting is 'myurl?t1=' + value of textbox1 + '&t2' + This will be blank; I want to make it dynamic, i.e.if there is not value in Textbox2 then I dont want to append queryparam t2, same goes for t1 also..isit possible?
