Passing the QUERY_STRING to the SSI via Javascript

[lgbjr]

Hi All,

OK, I have most of my problems worked out. I'm using the following SSI to put the search results on an SHTML page that is managed by a CMS:



But I need to get the search parameters from the URL. So, I'm using javascript:

<script language="javascript">
function getURLParam(){
var strReturn = "";
var strHref = window.location.href;
if ( strHref.indexOf("?") > -1 ){
var strQueryString = strHref.substr(strHref.indexOf("?")).toLowerCase() ;
strReturn = strQueryString;
//alert(strReturn);
}
return strReturn;
}
</script>


I've checked strReturn and it is set to ?zoom_query=MySearchString, but I am getting a Failed to execute CGI : Win32 Error Code = 2 error

If I take out the javascript and put the actual query string value into the SSI (just for a test):



everything works, so, it something to do with the way the SSI / javascript is being executed.

Any ideas?

TIA

Unfortunately, this will not work.

Javascript is executed on the client-side. This means that the script runs within the user's web browser, after the web page has been downloaded from the server.

The SSI is executed on the server-side. This means that the operation is executed before the page is downloaded off the server.

So when your SSI command is executed, the Javascript required to form the #exec command will not run and it would be unable to retrieve the URL parameters.

See my post on the other thread about my conclusion to this scenario:

Hi Ray,

Thanks for the info. Searching around the web, I did find some of the same info:

#exec cgi works fine, but...no parameters
#include virtual just includes the exe (but the parameters are passed from the URL (LOL)

So, onto ASP. I'm not an ASP person, so I have some simple questions:

Can I use the ASP code on a SHTML page? If so, I assume I need to put something in the Head section to tell the server that it should execute the ASP code?

TIA

To get ASP code to run within a .shtml file, you would have to change the Mapping configuration in IIS (under web site "Properties"->"Home directory"->"Configure"->"Mappings").

This may not be ideal if you need to perform other SHTML specific commands not available in ASP. However "#include" and many standard SSI stuff is properly supported in the ASP engine.

Hi,

OK, it's all good now. A bit of a kludge, but here's what works for me:

1. Created an ASP page with the code from the FAQ page
2. Added the following script to the head of my search page (/Search/index.shtml):

<script language="JavaScript">
function getURLParam(){
var strReturn = "";
var strHref = window.location.href;
if ( strHref.indexOf("?") > -1 ){
var strQueryString = strHref.substr(strHref.indexOf("?")).toLowerCase() ;
strReturn = 'http://10.75.47.80:8888/RNP/Search/srch.asp'+strQueryString;
}
return strReturn;
}
</script>

3. Added an iframe to my search page:

<iframe name="srchframe" id="srchframe" src="" frameborder="0" scrolling="yes" width="513" height="400"></iframe>

4. Added the following script below the iframe:

<script type="text/javascript">
var srchurl=getURLParam();
srchframe.location.href=srchurl;
</script>

5. In the Zoom configuration, set the Results Linking to Frame or Window: _top

6. In the Zoom configuration, set the link back URL to the ASP page I created

Works like a charm!

Thanks for your help!!

cheers
