My component has the functionality to load google map (Maps API version 3 with valid API key).

My infowindow above the marker stops working. One week back everything was smooth and working good.

Here is the code:

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=<API-KEY>&sensor=false"></script>
<script type="text/javascript">
map = new google.maps.Map(document.getElementById("map_canvas"), {
        center: new google.maps.LatLng(37.4419, -122.1419),
        zoom: 15,
        mapTypeId: google.maps.MapTypeId.ROADMAP,
        mapTypeControl: true,
        mapTypeControlOptions: {
            style: google.maps.MapTypeControlStyle.HORIZONTAL_BAR,
            position: google.maps.ControlPosition.TOP_RIGHT
        panControl: true,
        panControlOptions: {
            position: google.maps.ControlPosition.TOP_RIGHT
        zoomControl: true,
        zoomControlOptions: {
            style: google.maps.ZoomControlStyle.LARGE,
            position: google.maps.ControlPosition.LEFT_TOP

var marker = new google.maps.Marker({
                        map: map,
                        position: results[0].geometry.location

var infowindow = new google.maps.InfoWindow();
infowindow.setContent("Lorem Ipsum");
infowindow.open(map, marker); // On this line the problem is occurring

After investigating I noticed that it is not working due to mootools.js (version: 1.11) file. I cannot remove mootools files as it is breaking the default behaviour of the joomla.

The google map infowindow is working fine when I moved my code to non joomla project.

Below is the error which I am getting in the console log. Sharing first 2 lines of the error because it is big and it contains the API key.

Uncaught (in promise) Object { message: "View: element invalid: not an instance of Element", name: "InvalidValueError", stack: "ie@https://maps.googleapis.com/maps/api/js?key=......etc

Any help is very much appreciated. Thanks

  • Yikes. Joomla1.5! Say it ain't so. My sympathies. – mickmackusa Mar 31 at 22:28
  • How are map and marker being defined? Can you share the code for that? – Lodder Apr 1 at 5:33
  • Hi Lodder, I have updated my post to add code. Also shared complete code on githup (github.com/vbdeveloper1986/google_map). The code is working after commenting mootools_unminify.js script. Thanks! – Vallabh Bothre Apr 1 at 6:16

For this to work, MooTools needs to be loaded first, then jQuery (if this is being used) and Google Maps needs to be loaded last.

You can sometimes force MooTools to load first by adding this line high up in the <head> section of the template index.php file:

JHTML::_('behavior.framework', true);

Alternatively, download, install and enable the Joomla 1.5 version of jQuery Easy, set the plugin parameters so jQuery is not enabled, set up the advanced settings so that the MooTools script is stripped and then add the required scripts in the "Add Scripts" section so they load in the correct order (MooTools, then jQuery if this is being used and then Google Maps).

    Hi Neil, Thanks for your response. I created separate standalone file in which I included joomla mootools js file. Sharing code on githup (github.com/vbdeveloper1986/google_map). The code is working after commenting mootools_unminify.js script. There is something wrong in the mootools which is conflicting. Thanks! – Vallabh Bothre Apr 9 at 7:31
