trigger event on field losing focus

  • I’m working on this and am hoping you can help!

    I have a form which includes an email address.

    When a user inserts an email address and then LEAVES that field, I’d like this to trigger an event: opening a popup window using the contents of the field as a parameter.

    How can I hook into a field losing focus to trigger something?

    Many thanks for your help!

  • Hi @marathra

    You should be able to do it by using the jQuery focusout() method and acf/input/admin_footer hook to add the script. It should be something like this:

    function my_acf_script_focusout() {
        <script type="text/javascript">
                $(".acf-field-1234567890abc input").focusout(function(){
                    alert( $(this).val() );
    add_action('acf/input/admin_footer', 'my_acf_script_focusout');

    Where ‘acf-field-1234567890abc’ is based on the field key of your email custom field.

    I hope this helps 🙂

  • Thanks, with a tiny bit of tweaking it worked fine!
