Using the Waymark Callback Function
Adding a “Refresh” button to the Map.
Clicking on the “Refresh” icon located bottom right of the Map will reset the Map’s view so all Overlays on the Map are visible.
Route Map
To achieve this, we pass the name of a JavaScript function to the Shortcode like this:
Waymark map_id="1647" loaded_callback="waymark_refresh"The callback function, in this case waymark_refresh accepts a single argument, which is the Waymark Map instance. It will be called once the Map has loaded.
Once defined on your page (accessible in the global scope), we can use the instance object to perform additional actions. In this case, we are adding a button with a click event listener:
//Our callback function
function waymark_refresh(Waymark) {
//Get the container
let container = jQuery('.leaflet-bottom.leaflet-right', Waymark.jq_map_container);
//Create a button
let button = jQuery('<div />')
.addClass('waymark-refresh leaflet-bar leaflet-control')
.html('<a title="Reset Map"><span class="ion ion-android-refresh" style="cursor:pointer;margin-top:5px;font-size:20px"></span></a>')
.on('click', function() {
//Reset view when clicked
Waymark.reset_map_view();
})
;
//Add to page
container.prepend(button);
}
