Format date with "/" to "-" with javascript

Question

I have this Javascript function that takes X number of days and returns a date in the past

 var GetDateInThePastFromDays = function (days) {

        var today = new Date();
        _date = new Date(today.getFullYear(), today.getMonth(), today.getDate() - days);

        return _date.toLocaleDateString();
    }

That works absolutely fine, but it returns the date as 06/01/2016 but I want it returned as 06-01-2016 but I can't seem to find out how to do it correctly.

.toLocaleDateString() returns a string formatted according to the user's locale, meaning the format will match whatever is set on the user's machine. For me, that's 06/01/2016 but for an American it might be 01/06/2016 (because they're weird like that).

You should define your own format if you want a fixed one:

function pad(n) {return (n<10 ? "0" : "")+n;}
return pad(_date.getDate()) + "-" + pad(_date.getMonth()+1) + "-" + _date.getFullYear();
