ajax(https://codex.wordpress.org/Function_Reference/wp_localize_script) - Then make use of wp_ajax_{myfunction} (admin) and wp_ajax_nopriv_{myfunction}
-
And lastly implement your code inside that function
myfunction(){ /****Your code goes here*****/ }Eg. https://stackoverflow.com/questions/17855846/using-ajax-in-a-wordpress-plugin
