Customized tags on the map, here is part of the code in the js file
iconImageHref: 'img/label_map.png' I screw on WordPress and if it was php, I would just write:
iconImageHref: '<?php echo get_template_directory_uri()?>/img/label_map.png' Or something like that, and WordPress automatically set me on the right path. But this is a JS file, how to make sure that the path to the desired file is automatically and does not have to be set manually (you can make a mistake)
