Hello,

how to check the date in this format dd/mm/yyyy  in one field in adobe form is not less than current date and show app allert if the date is less than current?

I read this:
How to compare dates in Java? - Stack Overflow

But how can I use it in adobe pdf forms to check the start date is equal to  today date, if  it is less than today date then show me appalert message.

I tried this:

today.date = new Date();

var sStart = getField("fill_9").valueAsString;

dStart = util.scand("dd/mm/yyyy", sStart);

if ( new Date() < dStart) 

{

app.alert ( " alert"); 

} 

but it doesn't work.

Use this code as the field's custom validation script:

if (event.value!="") {
    var d = util.scand("dd/mm/yyyy", event.value);
    if (d.getTime()<new Date().getTime()) app.alert("You can't enter a date prior to today!");
}

But I want app alert only for less than  today date, and I don't want app alert when I put today date.

?

Use this, then:

if (event.value!="") { 
    var d = util.scand("dd/mm/yyyy", event.value); 
    d.setHours(23);
    d.setMinutes(59);
    d.setSeconds(59);
    if (d.getTime()<new Date().getTime()) app.alert("You can't enter a date prior to today!"); 
}
