Есть плагин Wordpress. При заполнении его формы происходит перезагрузка страницы. Надо выводить форму через модальное окно и чтобы оно не закрывалось после выполнения submit.
В форме нет (action="example.php"). Как найти скрипт, к которому можно было бы подцепить обработку формы через AJAX ?
Код формы

/* 
 * To ensure compatability, it is recommended you maintain class, id and form name attributes, unless you now what you're doing. 
 * You also must keep the _wpnonce hidden field in this form too.
