Question

I am trying to make a link submit a form. How come when I name a submit input element submit, the link no longer works?

 //breaks form submission
 <input type="submit" value="Submit" name="submit" />

 //does not break form submission
 <input type="submit" value="Submit" name="xsubmit" />

In Chrome I receive the following error.

Uncaught TypeError: Property 'submit' of object #<HTMLFormElement> is not a function

NOT Working

<p>Type 'correct' to validate.</p>
  <form method="post" enctype="multipart/form-data">
    <input type="submit" value="Submit" name="submit" />

    <a id="btn_submit">
        <span id="txt_submit">Submit</span>
    </a>
  </form>

<script>

$("#btn_submit").click(function() {
     $("form").submit();
    });

    $("form").submit(function() {

    });
</script>

“Submit” is a reserved word. It conflicts with javascript. Just change the name of the input to something else.

From the jQuery documentation on the method submit():

Forms and their child elements should not use input names or ids that
conflict with properties of a form, such as submit, length, or method.
Name conflicts can cause confusing failures. For a complete list of
rules and to check your markup for these problems, see DOMLint.
