Updating Google map markers using AJAX technology

Previously, everything was functioning well when the data was sourced from a static factory. However, now the data is being retrieved through an AJAX call ($http) from a remote server and for unknown reasons, markers are not appearing on the map.

Check out a working example here

If I uncomment the $http and switch to dynamic data instead of static data, the markers fail to display. Even though the variable markers is correctly populated with data, it does not reflect on the map.

This situation bears some resemblance to this problem

Answer №1

After the markers have been loaded, I find it helpful to set mode.state to true:

$scope.mode.state = false;
$scope.change_type = function(val) {
    var markers = [];
    $scope.eventMarkers = markers  // Clear the map of markers before loading new ones

    Events.venues(val.type).then(function(resp){
        var venues = $.map(resp.data, function(value, index){return [value]})  
        for (var i = 0; i < venues.length; i++) {
            event = venues[i]
            markers.push(createMarker(i,event))
        }
        console.log(markers)
        $scope.eventMarkers = markers
        $scope.mode.state = true;
    }, function(errror){
        console.debug(error)
    });
}
