Do you know that WordPress have a function called wp_localize_script(), which allow you to localize JavaScript strings? Here’s a practical example on how to use this little known but very useful function.
Simply paste the following code into your function.php file, where you generally enqueue scripts and styles. Line 4 shows how to use the wp_localize_script() function.
function prefix_enqueue_custom_script(){ wp_register_script( 'prefix_custom_script', plugin_dir_url( __FILE__ ) .'js/custom-script.js', array( 'jquery' ) ); wp_enqueue_script( 'prefix_custom_script' ); wp_localize_script( 'prefix_custom_script', 'prefix_object_name', array( 'upload' => __( 'upload', 'textdomain' ), 'remove' => __( 'remove', 'textdomain' ) ) ); }
Thanks to Devin for this code!
