如何从javascript循环中返回值？

Question

I'm iterating over an array with a some loop to see if a time is in the past but I also want to return how many times the loop has run, how do I do that?

arr.some(function(a, i){
            var date = Date.parse(a.start);
            var now = new Date().getTime();
            console.log(i);
            return now-date < 0;
        });

Edit: Solved this by just doing a for loop instead.

Answer 1

You can't return multiple objects in javascript. However, you can return a list of objects.

return [now-date < 0, i]

Answer 2

Count = 0;

arr.some(function(a, i){
        Count = +Count + 1;
        var date = Date.parse(a.start);
        var now = new Date().getTime();
        console.log(i);
        return now-date < 0;
    });

You could be able to make a counter, something like this.. basicly set count to 0 first and everytime the loop runs, count = old count + 1.
