setting day of week in javascript

I'm using the phonegap localNotifications plugin which specifies that I can set a notification to occur weekly.

However, it appears the javascript date object only has .getDay() and not .setDay().

I've got an json object of the days of the week I want to set to repeat,



set_days = {mon:false, tues:true,wed:false,thurs:true...}

how do you set a day in javascript? Because it is setting a notification, the day has to be in the future, so I don't want to get the most recent wednesday, but only the next wednesday.

here's a link to the plugin, but I don't think this is really specific to the plugin.

how do you set a day in javascript?

You mean, in the current week? When does a week start?

Assuming it starts on Sunday (as in getDay: 0 - Sunday, 1 - Monday, etc), this will work:

var date, daytoset; // given: a Date object and a integer representing the week day



var currentDay = date.getDay();

var distance = daytoset - currentDay;

date.setDate(date.getDate() + distance);

To set the date to a weekday in the next 7 days, use this:

var distance = (daytoset + 7 - currentDay) % 7;
