Question

I know this is easy, but I cannot seem to figure this out.

I am looking for the difference in date between two dates in javascript.

var date1 = new Date(document.getElementById("FromDate").value);  
var date2 = new Date(document.getElementById("ToDate").value);  

var date_diff = Math.abs(date2.getTime() - date1.getTime()/86400000);
        if (date_diff > 90){
              alert('Selection criteria can not exceed 90 days.');
        }

My date_diff value is something unrealistic.
What is wrong with my code above?

Answer 1

var date_diff = Math.abs(date2.getTime() - date1.getTime()/86400000);

should be

var date_diff = Math.abs(date2.getTime() - date1.getTime())/86400000;
