cfformitem type="script": How to set hidden field'svalue?

[cf_dev2]

I have a simple test form that contains a cftree and a few input/hidden fields.
Whenever a tree node is selected, I want to change the values of input/hidden
fields to whatever node was selected. Pretty simple, but I can't figure out
how to change the values of the hidden fields.

Load the form, select "ItemA" and click submit. The values of the hidden form
fields don't change. They're always "not set". What is the correct syntax for
changing a hidden field's value?




<cfdump var="#form#">
<cfform name="myForm" format="flash">
<cfformitem type="script">
function test(theValue:String):Void {
var valueString:String = theValue.toString();
title.text = "title = "+ valueString;
description.text = "description = "+ valueString;
myForm.theType.text = "theType = "+ valueString;
myForm.theID.text = "theID = "+ valueString;
}
</cfformitem>

<cftree name="itemTree"
onchange="test(itemTree.selectedNode.getProperty(' data').value)">
<cftreeitem display="ItemA" value="ItemA" parent="" expand="no" />
<cftreeitem display="ItemB" value="ItemB" parent="ItemA" expand="no" />
<cftreeitem display="ItemC" value="ItemC" parent="ItemB" expand="no" />
<cftreeitem display="ItemD" value="ItemD" parent="ItemB" expand="no" />
</cftree>

<cfformgroup type="panel" label="Add / Edit">
<cfformgroup type="horizontal">
<cfformitem type="text" style="fontWeight:bold;"
width="80">Title:</cfformitem>
<cfinput name="title" type="text" width="200" value=" " />
</cfformgroup>
<cfformgroup type="horizontal">
<cfformitem type="text" style="fontWeight:bold;"
width="80">Description:</cfformitem>
<cftextarea name="description" type="text" height="100" />
</cfformgroup>
<cfinput type="hidden" name="theType" value="not set" />
<cfinput type="hidden" name="theID" value="not set" />
<cfinput type="submit" name="submitButton" value="Submit">
</cfformgroup>
</cfform>

The correct syntax is

myForm.theID = "theID = "+ valueString;

That was it. Thanks! Weird that there's a different syntax for hidden fields.

Do you know if there any online references or documentation for scripting?
I've been using snippets from tutorials and trying to figure out the syntax
from flex documentation.

You will need to use a combination of resources.


1. CF Documentation

2. Flash Documentation

3. Flex Documentation

Thanks Ken, that helped. With the updated CF help files and Flash
documentation its starting to make a little more sense.

On a humorous note, I have to say it feels a little like the instructions are
written in Swahili and I'm using an English-to-Russian dictionary and then a
Russian-to-Swahili dictionary to read them ;-)

So that's my problem, someone stole my Russian-to-Swahili dictionary

Now that's funny ;-) I did hear a rumor that the next version is in Chinese. So you might skip the replacement and purchase a Russian-to-Chinese dictionary instead.
