Question

Does anyone know how can I get next week date based on this week date? example if I have this thursday date (25/6/2009) how can I use javascript to get next thursday date (2/7/2009)?

Answer 1

Date.prototype.addDays = function (d) {
    if (d) {
        var t = this.getTime();
        t = t + (d * 86400000);
        this.setTime(t);
    }
};

this_week.addDays(7);

Answer 2

var firstDay = new Date("2009/06/25");
var nextWeek = new Date(firstDay.getTime() + 7 * 24 * 60 * 60 * 1000);

You can also look at DateJS if you like "fluent" APIs.

Answer 3

function nextweek(){
    var today = new Date();
    var nextweek = new Date(today.getFullYear(), today.getMonth(), today.getDate()+7);
    return nextweek;
}
