Javascript add values to object dynamically

Question

Let's supose i have something like this:

$scope.playersData = [{ "label": obj.data[0].player, "color": colors[0], "data": obj.data[0].value }, { "label": obj.data[1].player, "color": colors[1], "data": obj.data[1].value }];

This works if i have always only 2 items in obj.data.

Now, if i want to add values dynamically in a For Loop, how do i do it?

I tried something like this, not working:

var temparray = []; for (var i = 0; i < data.length; i++) { temparray[i] = {"label": obj.data[i].player,"color": colors[i],"data": obj.data[i].value}; }

You can always use .push(), but even as it stands, that should be good enough. What exactly isn't working here? BTW, shouldn't you check for i < obj.data.length instead? — raina77ow

Can you try this?

var temparray = []; for (var i = 0; i < data.length; i++) { var item = {"label": obj.data[i].player,"color": colors[i],"data": obj.data[i].value}; temparray.push(item); //. <---added }

There is one mistake: replace from data.length to obj.data.length.

Also, you can use push for adding element to array.

var temparray = []; for (var i = 0; i < obj.data.length; i++) { temparray.push({"label": obj.data[i].player,"color": colors[i],"data": obj.data[i].value}); }
