Post comments on Facebook page via console

Question

Like in the image, the Facebook comment box has no submit button, when you write something and press Enter button, the comment posted.

I want to submit the comment via J

Answer 1

as I wasn't able to post comments through the "normal" facebook page, I remembered that they also have the mobile version, which is on m.facebook. com, there, they still have the submit Button, so depending on your needs, this may be a good option

so, you could go to the mobile facebook post (eg https://m.facebook.com/${author}/posts/${postId}) and do

// Find the input element that saves the message to be posted
document.querySelector("input[name='comment_text']").value='MESSAGE TO POST';
// find the submit button, enable it and click it
const submitButton = document.querySelector("button[name='submit']");
submitButton.disabled = false;
submitButton.click();
