JQuery autosubmit does not work in Safari

I have a form that I want to autosubmit using JQuery. However, it doesn’t work in older versions of Safari (macOS Mojave, iOS 12). It works in Chrome, Firefox, and iOS 13.

So, this is most likely a Safari bug, but I have a lot of users with devices running the older software, so I need to work around it.

Here’s my autosubmit code:

onclick="document.getElementById("flagging-remember-edit-form").submit();"

And to the submit button, I added style display: none.

Unfortunately, this doesn’t work in older versions of Safari.

I found an issue with a patch for a Drupal module that suggests using absolute positioning to hide the element, but when I tried this on my form, 1) it didn’t work in older versions of Safari and 2) it broke the submit in Firefox, too.

So how can I use JQuery autosubmit in old versions of Safari? (iOS 12 and below)

For reference, here’s the form from Drupal 8:

Answer

If you have jQuery, you don’t want to use HTML inline event handlers like onload.

Try using a <script> section, and use jQuery to submit the form.

<script>
$(function () {
    $("#flagging-remember-edit-form").submit();
});
</script>
