Add X months to a javascript date

I have the following design and I want to add six months to the start date on On-blur event but my code returns the finish date in millisecond format.

    function calDate() {
    var date1 = new Date(document.getElementById('txtstdate').value);
    document.getElementById("txtenddate").value = date1.setDate(date1.getDate()+30);

You need to use setMonth function here.

It should work like this:

function calDate() {
    var date1 = new Date(document.getElementById('txtstdate').value);
    document.getElementById("txtenddate").value = parseInt(date1.getDate()) + 30;
}

I just changed it to add as an Int instead of a string. It should work. – Cameron Jul 16 '16 at 23:43
