如何以自动提交的形式命名的JavaScript

Question

This is my code that I am using to submit form with post value

 <form action="<?php echo DOMAIN; ?>contact/booking-form.php" method="post">
  <input type="text" name="name" value="<?php echo $name; ?>" />
    <input type="text" name="email" value="<?php echo $email; ?>" />
    <input type="submit" name="submit" id="submit"  />
    <script>document.getElementById('submit').submit();</script>

<script>
  document.getElementById("submit").value = "newSubmitButtonValue";
</script>

Answer 3

A submit button is only going to be a successful control if it is used to submit the form (and even then only if it has a name and a value … which yours does not).

If you want submit=submit in your form data when you submit the form with JavaScript, then don't use a submit button to put that data in the form in the first place. Use a hidden input.

<input type="submit">
<input type="hidden" name="submit" id="submit" value="submit">

Then you have two other problems.

First, submit is a method of form elements, not inputs. So you need to change your script to call the right element.

<script>document.getElementById('submit').form.submit();</script>

Second, if a form has a control called submit then that will clobber the submit method. So you need to get one from a different form (not supported in old versions of Internet Explorer):

<script>
var form = document.getElementById('submit').form;
var submit_method = document.createElement("form").submit;
submit_method.call(form);
</script>
