show and hide fields based on a date range

[Darlhouse11]

Hello, I have been struggling with this for a while and can't find my exact situation out there.

How can I hide 2 text fields and 2 checkbox fields based on a particular date range?

I have a form that includes a date field,  after a certain date I don't want the fields to be available so I would like to hide those fields.

I tried the following, but I don't think I have the date syntax right. What am I doing wrong?

if(this.getField("Date").value >= "9/21/17"){   

this.getField("Text3").display = display.hidden;

}

else{

this.getField("Text3").display = display.visible;

}

Thank you so much in advance!

It's an empty string. If the field is empty (that is, has not value) we should not try to convert it to a Date field, because doing that will result in the current date, which is incorrect.

Is valueAsString strictly Acrobat JavaScript?

It's a property of the Field object, which only exists in the Acrobat JS API, so yes.
