Hooks

A "hook" in our parlance is, like in Wordpress generally, a place where you can "hang" a function that you want to run. Every hook recieves certain variables and can be registered to run on a specific map.

For example, let's say we need to resize the map in some special way after the page loads.

We'll register our hook before the map runs:

mwm.add_action('map_set', (map) => {
  // Do something with the map
  map.on('load', () => {
    map.setZoom(12);
  })
})

If you want to only target a specific map on a specific page, you can also pass the map ID (found by hovering over the map in the Maps > Maps screen, or in the URL when editing the map) to the hook function as follows:

mwm.add_action('map_set/mapster-7314', (map) => {
  // Do something with the map
  map.on('load', () => {
    map.setZoom(12);
  })
})

Examples

Here are a few script examples performing different tasks that might help you build your own.

Creating a Custom Zoom Event on Click of External Element

• Add IDs onto the elements to be clicked by looking at the Location IDs in the WP backend

• Set the zoom level you want in the click event from jQuery

// HTML
<div>
  <p class="map-office" id="map-office-578">Mount Vernon Office</p>
  <p class="map-office" id="map-office-577">Puyallup Office</p>
</div>

// JS
<script>
let allLocations = []
mwm.add_action('data_fetched', (postResponse) => {
  allLocations = postResponse.locations;
})
mwm.add_action('map_set', (map) => {
  map.on('load', () => {
    jQuery(document).on('click', '.map-office', function() {
       let thisId = jQuery(this).attr('id').replace("map-office-", "");
       let thisLocation = allLocations.find(location => location.id === parseInt(thisId));
       map.flyTo({ center : thisLocation.data.location.coordinates, zoom : 12 });
    });
  })
})
</script>
