Display other results in an iframe

Question

Hi All,
       I have this issue:
i am currently one abc.aspx page. and i have couple of search params on this page. when i search and click a button i need to display the results on a diff page.
following is the approach i am following.
when user clicks search.. taking all the necessary params and throwing them onto querystring which opens a new page.
when page opens reading these params from query string and tryin to assign it to an iframe [ to open that page ] .
but i cannot assign iframe src on fly.. below is the  code. am i missing something ??
<asp:Content ContentPlaceHolderId="PlaceHolderMain" runat="server">
<script type="text/javascript">
var tech = GetQueryStringParams('QS'); // actual funtion is on other page which reads querystring params.- this is workin
           fine.
alert(tech);
</script>
<script type="text/javascript">
$(document).ready(function(){
function myFunction1()
//if(tech != undefined)
//alert('Hi:' + tech);
alert('Hi');
$('#iframe_a').src = tech;
</script>
<iframe id="iframe_a" name="iframe_a" width="1000" height="1000" onload="myFunction1()"></iframe>
</asp:Content>

Go it guys,
               Somehow,  $('#iframe_a').src = tech; not workin instead tried
with 
$('#iframe_a').attr("src",
tech);
looks cool :)
thank you anyways.
