The integration of numerous filters in the Google Maps API allows for complex intersection

After weeks of searching, I finally found a solution for filtering multiple criteria using JavaScript and the Google Maps API. The functionality I found is exactly what I need for my map, but I'm struggling to get it to work properly. Can someone help me figure out where I'm going wrong?

@treighton, you can experiment with setting up markers with minimal details for testing purposes. For instance:

marker1 = new google.maps.Marker({
            title : title,
            position : pos,
            category : category,
            city : city,
            map : map
        });

By having a title, position, category, and city tagged in each marker, you can reduce the amount of code to write, making it easier to identify any issues that may arise. Once the markers are set up with filters, you can create a function for filtering (hiding and showing) them.

for (i = 0; i < markers1.length; i++) {
            marker = gmarkers1[i];
            // If the category matches or no category is selected
            if ((marker.city == city || city.length === 0) && (marker.category == category || category.length === 0)) {
                marker.setVisible(true);
            }
            // Categories do not match
            else {
                marker.setVisible(false);
            }
        }
