Question

I have been working with OrangeHRM for a project. It uses the Yui Calendar. I have been working on the leave module. The Leave module lets the user choose a From and To Date – A time frame for which he wants to apply leave !

I want to show the number of Working Days once the user has chosen the dates . A Simple Subtract statement would not work because I want to exclude the Saturdays and Sundays from the equations since they don’t count as working days !

function fillToDate(frmLeaveApp) {

    var fromdate = frmLeaveApp.elements['txtLeaveFromDate'];
        var todate = frmLeaveApp.elements['txtLeaveToDate'];
            var result = frmLeaveApp.elements['txtLeaveTotalDay'];

     if(!fromdate || !todate || !result) {
        return;
    }

        var a = fromdate.value;
        var b = todate.value;

        var c = a.split('-');
        var d = b.split('-');

        var ac = new Date();
        ac.setFullYear(c[2], c[1], c[0]);
        var bd = new Date();
        bd.setFullYear(d[2], d[1], d[0]);

        result.value = (bd.getTime() - ac.getTime()) / (60*60*24*1000);
}

How do I do it ? Thanks in advance !

Not super proud of this solution – must be more elegant ways, but it should work – does not handle national holidays yet

Demo here

function fillToDate(frmLeaveApp) {

    var fromdate = frmLeaveApp.elements['txtLeaveFromDate'];
    var todate = frmLeaveApp.elements['txtLeaveToDate'];
    var result = frmLeaveApp.elements['txtLeaveTotalDay'];

    if(!fromdate || !todate || !result) {
        return;
    }

    var from = new Date(fromdate.value.replace(/\-/g,"/"));
    var to = new Date(todate.value.replace(/\-/g,"/"));

    // brute force seems the quickest to find
    var res = 0;
    var aDay = 24*60*60*1000;
    for (var i = from.getTime(), n=to.getTime();i < n; i+=aDay) {
      var d = new Date(i).getDay();
      if (d!=0 && d !=6) res++;
    }
    result.value = res;
}
