Add days to date using javascript

Question

I am trying to add days to a given date using javascript. I have the following code

function onChange(e) {
    var datepicker = $(\"#DatePicker\").val();
           


        

Answer 1

Try

function onChange(e) {
        var datepicker = $("#DatePicker").val();
        alert(datepicker);
        var parts = datepicker.split(/[^\d]/);
        var joindate = new Date();
        joindate.setFullYear(parts[2], parts[1]-1, parts[0]);
        alert(joindate);
        var numberOfDaysToAdd = 1;
        joindate.setDate(joindate + numberOfDaysToAdd);
        var dd = joindate.getDate();
        var mm = joindate.getMonth() + 1;
        var y = joindate.getFullYear();
        var joinFormattedDate = dd + '/' + mm + '/' + y;
        $('.new').val(joinFormattedDate);

    }

I suppose the problem is JavaScript expects format MM/DD/YYYY not DD/MM/YYYY when passed into Date constructor.
