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

Date.prototype.addDays = function(days) {
    this.setDate(this.getDate() + days);
    return this;
};

and in your javascript code you could call

var currentDate = new Date();
// to add 8 days to current date
currentDate.addDays(8);
