Hi Walter,
The only example of this I could find was in the Navigation Action (line 814);
Freeway 5.5/Freeway 5.5 Pro.app/Contents/SharedSupport/Actions/ FAST/Navigation.fwactionb/Contents/Resources/Actions/Drop Down Menu.fwaction

I hope this helps in leu of some documentation.
Regards,
Tim.

That was what I found as well. Judging by how it’s used in the Action, I tried using it to get an object reference to a fwItem that was found using an action-itemref filtered picker, and failed miserably.

<action-itemref name="data" title="Data Source" filter="filterItems"/>
function filterItems(item){
	if(item == "")
		return false;
	if(item && (!item.fwIsLayer && !item.fwIsInlined || item.fwIsTableCell))
		return false;
	if(item && item.fwExportType != 1 && !item.fwIsLayer)
		return false;
	if(item && (item.fwFindAllActions(2,['com.wdstudio.html5_element']).length > 0))
	  return item;		
}

//inside fwBeforeEndBody
if(fwParameters.datalist.fwBoolValue){
  var sourcelist = fwParameters['data'].fwValue;
  element.list = fwQuote(sourcelist);
  var source = sourcelist.fwGetInstance();
}

At this point, source is undefined, but element.list is properly filled with the text value of the element found by the filterItems method.

Just realized this is not true entirely. source is defined, but it does not have a reference to any of the properties of the real “source” element. So if I call source.id, I get undefined.

Hi Walter/Tim,

fwGetInstance() is a FWLayoutElement method that will return the instance of a master item on a specified instance page.

FWLayoutElement fwGetInstance(ancestorPage);

If the FWLayoutElement it’s called on is not a master element, or no ancestor is specified, the element it’s called on is returned.

I’m pretty sure that’s the case anyway after a brief review of the code.

Hope this helps,

Stewart

That seems consistent with the result I found. Can you please spelunk a little more, and tell me how I could take a reference to a DIV on the current page and further manipulate it?

Given that I have an action-itemref that has acquired a target, let’s call it fwParameters.data, and I want to get a tag reference to that page element so that I can then look inside it for a child, using fwFind(‘select’), how would I get from that itemref reference to where I need to be?

Thanks,

Walter

Can you not use:

fwDocument.fwTags.fwFindAll(“select”, fwParameters.data.fwValue);

It’s a loooooooong time since I last wrote any Actions code in anger so this could be complete nonsense! Or I could have got the wrong end of the stick entirely…

That doesn’t seem to do anything. I’ve tried a number of variations on it and can’t find the key.

Thanks,

Walter

Ah, it’s not finding it because the owner of the select is not the parent item, it’s the menu/list item itself.

So you could do a fwFindAll(“select”) and then scoot up the tag tree from each found select comparing fwOwner against fwParameters.data.fwValue. Perhaps.

Is there a method I can call on a parameter to see what kind of beast it is internally? I’m thinking of typeof in JavaScript here, but I need something that’s aware of the internal Freeway DOM. The parameter is being temporarily cast toString() when I use it inside the fwQuote() and use it to set the ID of the list, but I wonder what it is before I do that.

Thanks again,

Walter

I don’t believe so.
