Question

Hello everyone,

I'm trying to create a PDF form where I'd like to hide 4 checkboxes if the date in the "Date From" field is
between 04/02/2023 and 05/03/2023.
If the "Date from" field is less than or greater than these 2 dates, then the checkboxes are visible.

Below what I started but it doesn't work at all..

Any ideas?

Thanks very much.

var date1 = "05/02/2023"
var date2 = "04/03/2023"
var date = this.getField("Date Du").valueAsString

if(date >= date1 && date >= date2) {

this.getField("LP 1h30 1").hidden = true;
this.getField("LP 1h30 2").hidden = true;
this.getField("LP 1h30 3").hidden = true;
this.getField("LP 1h30 4").hidden = true;

}
else {
this.getField("LP 1h30 1").hidden = false;
this.getField("LP 1h30 2").hidden = false;
this.getField("LP 1h30 3").hidden = false;
this.getField("LP 1h30 4").hidden = false;
}

What should happen if date field is empty?

You need to convert dates to date object to compare them.

To show/hide fields, use 'display' property, display.visible/display.hidden.

I assume those dates are in format dd/mm/yyyy?

You used >= for both condition in your script, second one should be <= also you said field name is "Date from" and in script you use "Date Du", as 'Validation' script of that field use like this:

 

var date1 = util.scand("dd/mm/yyyy","05/02/2023");
var date2 = util.scand("dd/mm/yyyy","04/03/2023");
var date =  util.scand("dd/mm/yyyy",event.value);

if(date.getTime() >= date1.getTime() && date.getTime() <= date2.getTime()) {

this.getField("LP 1h30 1").display = display.hidden;
this.getField("LP 1h30 2").display = display.hidden;
this.getField("LP 1h30 3").display = display.hidden;
this.getField("LP 1h30 4").display = display.hidden;

}
else {
this.getField("LP 1h30 1").display = display.visible;
this.getField("LP 1h30 2").display = display.visible;
this.getField("LP 1h30 3").display = display.visible;
this.getField("LP 1h30 4").display = display.visible;
}

    It's not a good idea to compare Date objects directly. You should use their getTime method for that.

    Here's an example of what can happen if you don't do that:

     

    var date1 = util.scand("dd/mm/yyyy","05/02/2023");
var date2 = util.scand("dd/mm/yyyy","05/02/2023");
console.println("Direct compare: " + date1==date2);
console.println("Time compare: " + date1.getTime()==date2.getTime());

    Yes, you are correct, script fixed, thanks. Although it may still give incorrect result because of timezones, it would be more precise to add time to the date format as well.
