Test for existence of field on form

Avatar

Level 2

Hello,

How do I test, using JavaScript, whether a specific field exists on a form or not?  I tried the following, but not  quite working:

if (xfa.layout.absPage(pg1.sfCap.sfCapLeft.Table2.Row2) == -1 )

{

}

Note: For the form where I tried this, the Row2 does not exist at all

Thanks!

The resolveNode function (see http://help.adobe.com/en_US/livecycle/9.0/designerHelp/001395.html) can be used to retrieve the value of a specific node within a table row. You will still need to determine the row count and iterate over the table row instances in conjunction with resolveNode().

You could test if the row count of a table. For example, form1.page1.subform1.table._row.count could be compared to form1.page1.subform1.table._row.occur.min to test if a new row had been dynamically added to the form.

So there's no exists() function that can return whether an item is found on a form or not?  I'm trying to create a fragment that will work for multiple forms, but part of the solution is that it must be able to determine if a certain item exists on a form AND that the code does not fail just because the item isn't found at all.  Thanks.
