Javascript Array filter not filtering

Question

I cannot get Javascript to filter a dynamically created array, although it filters a static array fine. Code block #1 works (static array), code block #2 doesn\'t (dynamically

Answer 1

Or, we can actually do

Array.prototype.filter.call(_eventsArray, function(_calendarEvent) { return _calendarEvent.unit == _unitValue; });

Answer 2

_eventsArray in your second example is an HTMLCollection not a JS Array. You can convert it like the following:

function getRowCalendarEvents (_eventsArray,_unitValue) {
    var arr = [].slice.call(_eventsArray);

    return arr.filter(function(_calendarEvent) {
    return _calendarEvent.unit == _unitValue;
  }); 
}
