Passed a value in between html pages in url won't work for switch statement.

[Frakes]

I'm using a hyperlink to pass a value from a home page to a search page. I'm using to values to identify and display only certain input/select boxs that relate to whatever unique search the user wants to use. I've gotten the value from "TYPE=VALUE " to display in my search page but now I'm wondering if it will work for my switch statement since none of my document.write statements are working.

Home Page links:

<BODY>                                            
<FORM NAME="HOMEPAGE" ID="HOMEPAGE" METHOD="POST">

<B>SEARCH FOR A CIR:</B> <BR />                             
   <A HREF="HTTPS://****.DSS.STATE.MO.US/YCRS?TYPE=REGION"> 
   <LI> SEARCH BY REGION </LI>                              
   <A HREF="HTTPS://****.DSS.STATE.MO.US/YCRS?TYPE=SUBMIT"> 
   <LI> SEARCH BY SUBMITTER</LI>                            
   <A HREF="HTTPS://****.DSS.STATE.MO.US/YCRS?TYPE=STUDENT">
   <LI> SEARCH BY STUDENT ID</LI>                           
   <A HREF="HTTPS://****.DSS.STATE.MO.US/YCRS?TYPE=DATE">   
   <LI> SEARCH BY DATE</LI> <BR/>
</FORM>
</BODY>

Search Page:

 
<head>  
<script>
function getparams(){                                                   
 var idx=document.URL.indexOf('?');                                     
 var params = new Array();                                              
   if (idx != -1) {                                                     
var pairs=document.URL.substring(idx+1, document.URL.length).split('&');
    for (var i=0; i<pairs.length; i++)  {

    stype = unescape(params["TYPE"]);              
    document.searchfunction.srchTYPE.value = stype;
</script> 
</body>

Any help would be much appreciated.

Implementing switch is possible. If you are using document.write it should be used during the page load. I tuned your code for local file and made some changes in the script. It seems working. Please have a look over your code and find where you can change.
