Callout not passing values to SELECT item on DCR

jstephan

Hi,

I am trying to pass values from a callout window to DCR Select Item.
It passes the value from Callout and changes the DCR Select Item list based on the value. But its not storing the value in the DCR Select Item field.

Even though it changes the DROP DOWN SELECT LIST, its not storing the value to the ITEM FIELD.

It works good with TEXT item.

Please advice.

Thanks in advance.
John

From your callout code write the output to a log file and post it along with the appropraite portion of the DCT

<item name="page_picker" pathid="#page_picker">
<label>Page Picker</label>
<text size="10">
<callout url="/iw-bin/page_picker.ipl" label="Picker" window-features="width=650,height=350,resizable=no,toolbar=no,scrollbars=yes" />
</text>
</item>

<item name="page_title" pathid="#page_title">

<item name="page_name" pathid="#page_name">

<select required="t">
<option value="0" label="Select One" />
<option value="1" label="Home Page" />
<option value="2" label="Level 1 Page" />
<option value="3" label="Level 2 Page" />
<option value="4" label="Level 3 Page" />
<option value="5" label="Level 4 Page" />
</select>

The page picker has to pass values to page_title and page_name. It works fine and stores value on page_title. It pass values and changes the select drop down list. But not stores the values to the field.

Call Out Values:
For Page Title = "Test Value of Page Title"
For Page Name = 1

Thank you.

OK, I am not certain about how this is supposed to work.

Someone changes the page_picker and from the change some JS changes the page_title and page_name ?

Thank you Nipper for your quick replies.

The page_title and page_name are not editable. It has to be generated thru the page_picker. Values been passed from page_picker callout to page_title and page_name on DCT.

The javascript code on callout window to pass value to page_name on DCT:

if (calloutForm.elements.name == "page_name") {
calloutForm.elements.value = generated_page_name;
}

select lists do not work that way

You need to use setOptions() to replace the selected option. Read the formapi manual.

How do i set the IWItem for a Callout function window to work with setOptions?

nipper

read page 17 of the 6.7 FormAPI manual

jstephan

This is the function which returns the value to select item from a CALL OUT window to DCR.

function set_datacapture_item_value( selectedValue )
{
var calloutForm = eval($form_name);
for ( i = 0 ; i < calloutForm.elements.length ; i++ )
{
if (calloutForm.elements.name == '$element_name')
{
optionsObject = calloutForm.elements.options;
optionsLength = optionsObject.length;
for (var z=0; z {
if (page_name == optionsObject.value) {
optionsObject.selected = true;
optionsObject.value = page_name_id;
calloutForm.elements.value = page_name;
}
}
break;
}
}
return true;
}

Possible values for page_name_id = 1 or 2 or 3 or 4 or 5.
Possible values for page_name = Home Page, Level 1 Page, Level 2 Page, Level 3 Page, Level 4 Page

But its not storing the value into the drop down.

read page 17 of the 6.7 FormAPI manual

IWDatacapture.getItem("/page_name") - Returns Error

So i can't use IWDatacapture.getItem("/page_name").setOptions() on the callout script to set values.

function set_datacapture_item_value( selectedValue )
{

{
if (calloutForm.elements.name == '$element_name')
{
optionsObject = calloutForm.elements.options;
optionsLength = optionsObject.length;
for (var z=0; z {
if (page_name == optionsObject.value) {
optionsObject.selected = true;
optionsObject.value = page_name_id;
calloutForm.elements.value = page_name;
}
}
break;
}
}
return true;
}

Possible values for page_name_id = 1 or 2 or 3 or 4 or 5.
Possible values for page_name = Home Page, Level 1 Page, Level 2 Page, Level 3 Page, Level 4 Page

But its not storing the value into the drop down.

The above is ancient pre-FormAPI code for callout scripts to interact with DCTs (more in response to other post)

IWDatacapture.getItem("/page_name") - Returns Error

So i can't use IWDatacapture.getItem("/page_name").setOptions() on the callout script to set values.

Please try re-reading the FormAPI manual - look for information about getScriptFrame - and then search the forums here for the same.

It will be a bit odd at first because you're used to the ancient code you posted - but once you get used to it - you'll find it's a lot better.

Thanks for all your responses.
Got the solution for the old method code itself. Finally it worked once refreshing the item after storing the value.
Code: opener.top.datacapture.refreshItem(calloutForm.elements);

[
The manual mentions getScriptFrame returns value when we use callServer.

Frame (top level of data capture form/parent).getScriptFrame ()
This function is defined at the top level of a data capture form. If this is being called from JavaScript returned by callServer(), you will probably need to invoke it from the parent object. Returns the frame containing the API and user scripts. It is designed to be used in the JavaScript returned by the callServer() method to access functions and variables in the user script frame.

I don't know how to integreate the callServer for a callout function. Thanks Ghoti for your response.

The structure reference from a CGI callout is a bit different - but not that different - I think it's opener.top.getScriptFrame or opener.getScriptFrame or something along those lines - try one of those and you should find it - once you do you can use it to access DCT fields (and other FormAPI functions you've defined) in a supported manner.
