domObj.ancestor
(Merge only)
Determine if an object has an ancestor (not necessarily just an immediate parent) of a given name.
Syntax
domObj.ancestor(name)
Returned Value
The domObj pointer of the ancestor with the supplied name, or null if no ancestor with that name exists.
Parameters
name is a string, which is the name of a, considered by you to be a possible, ancestor of this object.
Description
Often a form designer inserts more hierarchy into a form design for various reasons. Script is over 'brittle' if it uses constructs such as this._parent._parent... so as to get the object of some nearby ancestor. By using this ancestor function, coding is both easier and more maintainable.
