Hi Dave,

Thanks for your answer.

What I'm trying is to use TeamSite::CGI_lite and get item value in ipl but am unsuccessful in it.
Is there any reason it shouldn't be returning me any value.

I'm doing GET on "callserver" in javascript and passing the value selecting by the user but in return I'm unsuccess in retrieving value.

I would really appreciate your help.

Thanks,

Okay, I thought your question was a general one about CGI::Lite. I don't think I understand what you're doing, though. Please attach your IPL and provide more context.

I think I understand that you're trying to use this in a DCT and are trying to pass something from a CallServer to a textarea (or textfield, whatever)? You will almost certainly need to use FormAPI here, but again, I'm not sure that I understand your situation properly.

Yes you are right. I'm trying this in DCT.

What I've is a dropdowlist box and onchange event of dropdownlist box it calls javascript and populates value in textbox.

Below is my ipl snippet.
---------------------------------------------------------------------------------------------
<script><![CDATA[
var params = new Object();
function init()
{
IWEventRegistry.addItemHandler("/Label1", "onItemChange",onchange);
IWEventRegistry.addItemHandler("/Label2", "onItemChange",onLNameChange);

}
function onLNameChange(item)
{
var api = parent.getScriptFrame();
}
function onchange(item)
{
var myOptions = item.getOptions();
params.category = myOptions[parseInt(item.getValue())].value;
IWDatacapture.displayMessage("Retrieving locations in " +
myOptions[parseInt(item.getValue())].text + "...");
top.hiddenFrameRunning = true;

IWDatacapture.getItem("/Label4").setValue(params.category);
var server = window.location.hostname;
IWDatacapture.callServer("http://"+server+"/test.ipl",params,true);

}
init();
]]></script>

<item name="Label1">
<label>State</label>
<description><![CDATA[<br/><a href="javascript&colon;datacapture.virtualize(parent.dataform.vpath.value);">Select an intern</a>]]></description>
<select>
<option label="None" value="Select State" selected="true"/>
<option label="None" value="IL" selected="true"/>
<option label="None" value="CA" selected="true"/>
</select>
</item>
<item name="Label4">
<text name="Label5" size="12" maxlength="25" required="t" validation-regex="^\\d\{1,2\}\$"/>
</item>
<item name="Label2">
<label>Last Name</label>
<description><![CDATA[<br/><a href="javascript&colon;datacapture.virtualize(parent.dataform.vpath.value);">Select a Last Name</a>]]></description>
<select>
<option label="None" value="1" selected="true"/>\n"
</select>
</item>
---------------------------------------------------------------------------------------------
Now what I'm trying is once i select "Label1" value from droplist I go and populate selected value in textbox and retrieve that value and query to db.

Thanks

Okay, so it sounds like you're not filling in the textarea. Do you know that your onchange function is even being called? I doubt this is the issue but I'd stay away from naming functions that way -- reason is it's very close to a reserved word (onChange, of course) and I don't think that JS cares about case sensitivity but you may want to stay away from that.

Otherwise, you seem to be calling in several lines what might be able to be done in one. For instance, you could retrieve the selected text as:

item.options[item.seletedIndex].text

What you're doing may be entirely fine but it's a bit lengthy. What happens when you put alerts in your onchange function?

Yes it does get call and see the value. Only problem is how do se set client side value to server side (i.e. perl). As I want that value and than query it to DB.

Migrateduser

You could do something like:


var retrievedValue = IWDatacapture.callServer("http://"+server+"/test.ipl",params,true);

and then set whichever field's value to retrievedValue. In your IPL, you would run your query and then return a value. This is where retrievedValue would come from.

the alert for params.category before callserver gives me the value of what i have selected in the first drop box

Sorry, I had deleted that post because I realized that not where your problem was. Check out my previous post.

Dave - CallServer is (a) asynchronus and (b) returns nothing - to the suggestion of:

var retrievedValue = IWDatacapture.callServer("http://"+server+"/test.ipl",params,true);

is pointless.

As for accessing the information in the Perl code:...
use TeamSite::CGI_lite;
my $cgi = TeamSite::CGI_lite->new();
$cgi->parse_data();
my $category = $cgi->{form}{category};
... should do the trick (since params.category was filled in within the DCT code)

I already had callserver api. but it doesn't look like it is returning any value though assigning it to variable. It show mes "undefined".

Migrateduser

Thanks... it's been a couple of years since I've needed to use callServer, so I wasn't sure. I was actually trying to go by the documentation which is sadly sparse.

I know there's an example script called getLocations.ipl underneath iw-home/examples/templatedata which is a callServer and does something perhaps similar to what coltrane wants to so (without the database call, of course).

Thanks for the reply. But still no success.. I don't see anything returning when i use

use TeamSite::CGI_lite;
my $cgi = TeamSite::CGI_lite->new();
$cgi->parse_data();
my $category = $cgi->{form}{category};

I think all depends on callserver. Looks like my callserver is not retriving any data back.

Adam Stoller

Are you sure your perl script is getting called?
IWDatacapture.callServer("http://"+server+"/test.ipl",params,true);

Where is test.ipl actually, physically located?

It should be in IWHOME/httpd/iw-bin/
If so, I believe the URL should be "http://"+server+"/iw-bin/test.ipl"

Thanks fish.. Yes it is in httpd/iw-bin and url is correct. But it show me blank. Is it because I have a globalize variable in perl script ?

coltrane30

ok.. another question arises is I have a ipl file and I'm calling callserver inside ipl file. Does that have to do with anything ?

For those of you like me who turn to these boards for "useful information" to help you with your coding dilemas, the above mentioned RTFM reference may not have been all that helpful.

The general CGI::Lite perldoc is not particularly useful in coding for TeamSite::CGI_lite. In this case try examing the following instead:
--> iwperldoc TeamSite::CGI_lite

Much more useful information there.

If you're not familiar with perldoc at all, you can find this by typing the above stated line in your terminal session on the TeamSite box. You may need to adjust for your environment if you do not have a enviro variable for the teamsite bin path.

Hope that helps somebody else who came across this info needing some help.

Dave,

I feel you can't collect the returned value of call server in the same function where ipl is called.

i feel there needs to another function inside JS which needs to be used inside parent script frame to return value to JS.

Thanks,
