[forms+flow] repeater widget onClick property

[Mark Lundquist <ml...@wrinkledog.com>]

I'm using Cocoon 2.1.5_dev w/ the v2 forms+flow API...

I've got an <fd:action> as a child of a repeater.  This is supposed to 
be a "Delete" button that calls removeRow() on the repeater for its 
row, but I can't figure out how to know, within the fd:action's onClick 
handler, the index of the row whose delete button submitted the form.

Is there a nice way to do this?

Thanks a lot,
Mark

This should work:

button.onClick = function() {
  var row = button.getParent();
  var repeater = row.getParent();
  repeater.removeRow(parseInt(row.getId()))
}

But I think it would be a good idea to add a getRowIndex() to the JS 
RepeaterRow object. Maybe a remove() operation should be added to JS 
RepeaterRow as well.

Thanks... getWidget("id") didn't work for me — it returned null, as did 
getWidget("rowID") which I saw on some Wiki page that Joerg referenced, 
so maybe that's out of date w.r.t. the version of Cocoon I'm using.

getID() per Chris Oliver's suggestion worked.

 From flowscript, you assign to the 'onClick' property of the 
<fd:action> widget.  For instance, if you have a row object in a 
repeater containing a <fd:action> named someButton as a child, you can 
write:

	row.someButton.onClick = function () { ...whatever };

I believe you need to be using the "v2" forms+flow integration for this 
to work.

I have the same problem. The best solution i found so far is to refer by 
form's submit widget, i.e.:

    var selected = 
form.getWidget().getSubmitWidget().getParent().getWidget("id").value;

By the way, how do you install repeater's fd:action onClick handler?
