Opening Info Windows

If your map includes info windows, users will typically open them by clicking on each corresponding marker. Sometimes, however, you'll want something outside of the map to open an info window.

The snippet below includes three parts:

  1. A dynamic map, containing markers for all entries.
  2. A list of entries. Clicking on each title will open its corresponding info window on the map.
  3. The JavaScript function which handles switching between info windows.
{# Configure the map options #}
{% set options = {
    'id': 'my-map',
    'infoWindowTemplate': 'example/my-info-window'
} %}

{# Display a dynamic map with all entries #}
{{, options).tag() }}

{# Loop through all entries #}
{% for entry in entries %}

    {# Compile each marker ID #}
    {% set markerId = "#{}-myAddressField" %}

    {# On click, open the info window of the specified marker #}
    <div onclick="infoWindow('{{ markerId }}')">
        {{ entry.title }}

{% endfor %}

{# JavaScript function to switch info windows #}
    function infoWindow(markerId) {
        googleMaps.getMap('my-map')    // Get the map
            .closeInfoWindow('*')      // Close all info windows
            .openInfoWindow(markerId); // Open the specified info window

The openInfoWindow and closeInfoWindow methods are available in JS, Twig, and PHP.

Usage is nearly identical across all three languages, although you will have more versatility when using it in JavaScript (since Twig and PHP are only relevant when the map is first loaded).
