javascript - Get current field name in to change display option? -

i've looked afternoon try , find one. basically, want name of current text field , change display value noprint if text field value "--". i'm running validation script in pdf. appreciated!

if(event.value == '--')  {     event.target.name.display = event.target.name.display.noprint; } else  {     event.target.name.display = event.target.name.display.visible; }  

you have couple of things bit off.

event.value doesn't exist (you can check available event properties)

if want value of element triggered event can do:

var elemvalue = event.target.value; 

if want name same element can do:

var elemname = event.target.name; 

to hide element printing, can see this answer.
