returning varialbe to formapi script from cgi

kellyrmilligan

I am using call server to determine a file size.

here is the javascript portion:

function getSize(item){
if ( IWDatacapture.getItem( "/PDFLinkContainer/PDFLinkReplicant" ).getChildren() != null )
{
for( i = 0 ; i < IWDatacapture.getItem( "/PDFLinkContainer/PDFLinkReplicant" ).getChildren().length ; i++ )
{
var index = i + 1;
// do something with "/Data/Sections[" + index + "]/SectionBody";
var path = IWDatacapture.getItem("/PDFLinkContainer/PDFLinkReplicant[" + index + "]/File_Name").getValue();
path = "/iwmnt/default/main/BCBSTX/Providers/WORKAREA/Content" + path;
//alert("The path going in is " + path);
var params = new Object();
params.path = path;
IWDatacapture.displayMessage("Determining file sizes ...");
top.hiddenFrameRunning = true;
var server = window.location.hostname;
IWDatacapture.callServer("http://"+server+"/iw-bin/file_size.cgi", params);
}
}
} //endfunction

I then want to return this value(size of file) to the javascript in a separate function:

function receiveCgi(cgisize){
IWDatacapture.displayMessage();
IWDatacapture.redraw();
alert(cgisize);
}//end f

This is just for testing, I will eventually set the value of another field. The perl code below is used to send the value back to the js

print <<EOT;

<html>
<head>
<script language="javascript">
var size = $cgisize;
alert(size);
</script>
</head>

<body onload='parent.getScriptFrame().receiveCgi("size")'>
</body>

</html>

EOT

close LOG;
exit;

I am not getting any thing in the dcr in the form of an alert or anything. any ideas?

I am not sure if the code on this post is the complete listing or an excerpt. I will assume that it is the complete listing.

There are several things you can check.
1. Is the formapi enabled?
2. Is getSize() getting called?
3. Is your CGI getting hit?
4. Is your CGI response well-formed HTTP?

For item 1, just make sure you have the following in your iw.cfg file:

[teamsite_templating]
enable_formapi=true

For item 2, make sure getSize() is either registered to handle an event on the form, or is called by a handler...

To check for item 3, you can either look at your webserver logs (in this case, the log files under $IWHOME/iw-webd/logs). You might also want to alert the URL you are passing into callServer() and try hitting that URL manually in a browser to see if it responds.

The above also tests for Item 4. I did notice, however, that you are missing the Content-type header information in your CGI response. You might want to add something like:

print "Content-type: text/html\n\n";

if it isn't there already.
