Why am I unable to access the array once the loop has finished?

While utilizing the Google Maps API and AngularJS (1.5.8), I encountered an issue where I couldn't access markers that were created in a loop. The code snippet below is located inside the initMap function:

var markers = [];

for(var i=0; i<10; i++){

    var html = $scope.posts[i].address;

    var marker = new google.maps.Marker({
        map: map,
        position: {lat: parseFloat($scope.posts[i].lat), lng: parseFloat($scope.posts[i].lng)}
    });

    markers.push(marker);

    bindInfoWindow(markers[i], map, infoWindow, html);

}

markers // no error messages, nothing
console.log(markers); // still nothing

EDIT:

The error was in

for(var i=0; i<10; i++){

Changed to:

for(var i=0; i<$scope.posts.length; i++)

I am grateful for @Maxx's guidance and appreciation of everyone who attempted to assist. This turned out to be a simple oversight.

Answer №1

Issue: $scope.posts[i] is not defined"

An error occurs in the script when it reaches the line

var html = $scope.posts[i].address;
. The script halts at this point, and as a result, it does not proceed to execute console.log(markers);

However, markers are displaying on the map despite the error message

The problem lies within a loop where some markers display successfully, but then one of the values becomes undefined (not the first value), triggering an exception that causes the script to stop.

To fix this issue, consider looping up to the array's length instead of relying on a hardcoded 10 items limit.

, make a note of the error for later analysis.

It's crucial to address the initial error first because often, they serve as triggers for subsequent errors.
