callserver retrieving perl variable?

Digger

Hi,
Having problem sending perl variable.
The attach script are working OK as long as I don't try to send a perl variable...
1.datacapture.cfg
2.mik.js
3.getContent_callserver.ipl

Here my situation:
1.Calling callserver with parameters.(parameter are receive from the formAPI)
2.getContent_callserver.ipl is executing properly(Parameter are sent only if javascript variable)
3.I'm trying to return a simple perl variable from that script with no success.

Example: I want to return the variable $return_content
=================================================
my $return_content=$data->{english}->{$chapter}->{$section}->{$content_txt};
[html]

print <

// var testing = $return_content;
var testing = "a string that mean nothing";

// calling the javascript function on the client side

EOT
[/html]

Note: I'm able to pass the parameter "testing" but not "$return_content"?
Can somebody tell me what's the proper approach.
Regards,

The code didn't show properly let me tried again:

[html]
my $return_content=$data->{english}->{$chapter}->{$section}->{$content_txt};

print <

// var testing = $return_content;
var testing = "a string that mean nothing";

// calling the javascript function on the client side

Are you sure it is the Perl to JS ? Can you put this in the IPL ?

my $return_content= "a string that mean nothing";

In the ipl, modify your EOT output to somethinh like the following:

print <<EOT;
<html>
<body onload="parent.getScriptFrame().populateLocations('$return_content')">
</body>
</html>

i think the problem you have is with code that parsing the xml. make sure this code works first and it is returning data before plugging it in ur ipl

Hi,
The parsing is done properly and the string I'm looking gets return properly from the script, it's when I'm trying to send the result back that I have problems.

In the ipl, modify your EOT output to somethinh like the following:
print < 
'$return_content')">

I've tried with single quote, double quotes, reverse quote with no success, I'm I usig the proper approach for parameter beetwen callserver?

Ok. Let's dissect your code a little. You said before: "I'm able to pass the parameter "testing" but not "$return_content...".

So, an assumption is that this works:
//var testing = $return_content;
var testing = "a string that mean nothing";

And this does not:
var testing = $return_content;
//var testing = "a string that mean nothing";

Assume that $return_content value is 'Foo'. Then, Shell-Style "Here Document" (<<) evaluates to var testing = Foo;
Guess what, it's wrong JavaScript, you do not have a JS variable Foo!
Correct syntax would be var testing = '$return_content'; to make Foo a literal.

By the way, unless it's a typo your posted mik.js does not actually contain "IWDatacapture.callServer" command.
But then again, you said that "testing" worked.

You still need to verify that this actually returns something:

my $return_content=$data->{english}->{$chapter}->{$section}->{$content_txt};

That is why I said yesterday to set return_content to a string, or you could log it to a log file, verify that here is indeed data in that variable.

Thx, I was able to assign a variable and populate the area with a simple string.
But know I wanted to pass this string as an example and it doesn't like it.

Since you have double quotes in the string, you should try to change the double quotes in the parent.etc to single quotes. You may need to escape a second set of quotes as well.

i am guessing the data u are passing is breaking your xml file. try to escape it with CDATA and see.

Well, you are guessing wrong. If you read Digger's "mik.js" module you saw that he used IWItem.setValue method to set
item's value. This method escapes HTML Data, it simply won't allow you to malform DCR. Your CDATA for example
will be stored verbatim, as <![CDATA[ . . . ]]>

I can practically guarantee that Digger's problem is that getContent_callserver.ipl either outputs syntactically
wrong Java Script in the first place or this JS fails upon rendition by the Form's browser.

Your right, my problem was a "\n" at the end of my content string, once I've removed it worked.

I will like to thx you all for helping me with this.
