The form reports success and never submits

The symptom. You fill a form, click submit, get succes: true, and the target is unchanged. Reading the page afterwards shows the same page, never the result you expected.

Two unrelated causes give this same result. Tell them apart before choosing a fix.

Cause 1: the browser blocked the submission

HTML5 validation. A field marked required is empty, or a type="email" field holds something that is not an address. The browser refuses to send the form and shows a small message next to the field.

Dinoer reports the click as successful, because it was: the click happened. The browser declined to act on it.

How to recognise it. Nothing was sent, so nothing loads: in latences_actions, an attendre_navigation placed right after the click returns at once. To see which fields block, ask the page:

{"type": "evaluer",
 "script": "Array.from(document.querySelectorAll(':invalid')).map(e => e.name || e.id)"}

The fix. Fill the missing field. If it must stay empty on purpose, submit the form directly, which skips native validation:

{"type": "evaluer",
 "script": "document.querySelector('#my-form').submit()"}

Cause 2: a click from JavaScript is not a user’s click

Calling .click() on a submit button from JavaScript produces an event marked isTrusted: false. Scripts on the page can ignore or cancel such an event, and some do: the scenario ends succes: true and the form was never sent.

{"type": "evaluer",
 "script": "document.querySelector('input[name=upgrade]').click()"}

The fix. Prefer a real cliquer on the button: Playwright’s click is treated like a user’s. From evaluer, submit the form itself:

{"type": "evaluer",
 "script": "document.querySelector('input[value=\"theme-slug\"]').closest('form').requestSubmit()"}

requestSubmit() runs validation and the form’s own submit handlers, as a user’s submission does. submit() skips both: use it only when you know the form posts directly to the server.

The rule worth keeping

To submit a form, prefer cliquer on the button. From evaluer, call requestSubmit() on the form, never .click() on the button.

Before you conclude

A submission that seems to have failed may have succeeded. A slow request (an import, a copy, anything that takes tens of seconds) can exceed the timeout while the server carries on and finishes the work. A TimeoutError on a click means that Playwright stopped waiting, not that nothing happened.

Check the target before retrying, or you will run the operation twice. The operation that takes a while →

In short

• Two causes, one symptom: native validation blocked the form, or a JavaScript .click() was ignored.
• evaluer with :invalid lists the fields that block.
• Prefer cliquer; from evaluer, requestSubmit() on the form.
• A timeout is not a failure: check before you retry.
