Comparing two dates in javascript

Comparing two dates in javascript
  • Edit your end date element.
    Add a new blur event with the following code:

    Code (Javascript):

    var startid= 'jos_events___start_date_cal';
     
    var endid = 'jos_events___end_date_cal';
     
    var start = document.id(startid).get('value').split('-');
     
    var end = document.id(endid).get('value').split('-');
     
    if (start.length > 1) {
      var startdate = new Date();
      startdate.setFullYear(start[0]);
      startdate.setMonth(start[1].toInt() - 1);
      startdate.setDate(start[2]);
      var enddate = new Date();
      enddate.setFullYear(end[0]);
      enddate.setMonth(end[1].toInt() - 1);
      enddate.setDate(end[2]);
      if (enddate < startdate) {
        alert('woops your end date is earlier than your start date');
        document.id(endid).value = [I];[/I]
      }
     
    }
     
    Edit it so that the first two lines point to the id's of your start and end date fields. This also presumes that your date elements are recording the dates in the format 'yyyy-mm-dd';
