the target path of the text field, in slash syntax

theField._target
Description
The _target property represents the path to theField in a Flash 4-style slash notation string. For example, if name_txt resides on the main movie timeline, name_txt's _target property is "/name_txt". To convert the slash-style path to an object reference, use eval( ). To retrieve a string giving the path to a text field in dot notation, use the global targetPath( ) function. Because slash notation is deprecated, this property is not used commonly and is supported for legacy reasons only.
