Ensuring Google Maps is Fully Initialized before Initiating JavaScript Processes

Integrating Google Maps into websites introduces a dependency on its complete loading before executing certain JavaScript functions. The tilesloaded() method, intended for this purpose, often fails to provide a reliable indication of full loading. This raises a pertinent question:

How to Determine Completion of Google Maps Loading?

To address this, a more dependable approach is to utilize Google's event handling system:

<code class="javascript">google.maps.event.addListenerOnce(map, 'idle', function(){
    // Do actions once Google Maps is fully initialized
});</code>

The "idle" event triggers when Google Maps reaches an idle state, indicating that all tiles and elements have completed loading or encountered errors. By using the addListenerOnce method, the specified function executes only during the initial occurrence of the "idle" event, ensuring that actions are performed only after complete initialization.

Reference:

For further details on event handling, refer to the Google Maps Reference's events section. Using the "idle" event provides a robust and accurate way to verify the full loading of Google Maps, enabling you to seamlessly initiate JavaScript processes once initialization is complete.
