Acrobat DC - How to make a field fillable only when previous field is populated?

[kyler2019]

I'm looking to set up a document in a way that someone filling it out can only populate fields once all preceeding fields have been populated. Would there be a way to do this?

There is couple of ways to do that, by making fields read only or hidden until previous field is populated.

Example:

Lets say you have field1 and field2, you don't won't field 2 to be fillable until field1 is filled, you can make field2 read only like this: as validation script of field1 use this:

this.getField("field2").readonly = event.value == "" ? true : false;

or to make it hidden:

this.getField("field2").display = event.value == "" ? display.hidden : display.visible;

Since it's validation script for first time set fields to read only/hidden manually.
