The reason why the form could not be submitted and the solution

Directly on the code put:

<div id="register">

<h4> Registered members </h4>

<div class="formdiv">

<form method="post" action="register.php?action=register" name="register" id="registerForm">

<dl>

<dt> Please fill in the following carefully </dt>

<dd class="hasspan">

 User name: <input type="text" name="username">

</dd>

<dd class="hasspan">

 Password: <input type="password" name="pwd">

</dd>

<dd class="hasspan">

 Confirm password: <input type="password" name="pwdagain">

</dd>

<dd id="tximg">

<img src="img/face/m01.gif" alt=" Choose picture " id="faceimg">

<input type="hidden" name="touxiang" value="">

<label id="imgsrclabel">m01.gif</label>

</dd>

<dd style="margin-right:120px;">

 Verification code: <input type="text" name="code">

<span>

<img src="code.php" alt="code" id="code" name="code">

<a href="#code" id="change"> In a </a>

</span>

</dd>

<dd class="btns">

<input type="button" name="submit" id="submit" value=" registered ">

<input type="button" name="quit" id="quit" value=" exit ">

</dd>

</dl>

</form>

</div>

</div>

 Form data is submitted to this page, below js To deal with 



function formDeal()

{

var btnSubmit = document.getElementById('submit');

var formId = document.getElementById('registerForm');

btnSubmit.onclick = function()

{

//The submit() method of the form cannot submit the form

formId.submit();

}


}

 If the form is submitted, there is a prompt on this page 

if(!empty($_GET['action']) && $_GET['action'] == 'register')

{

echo ' You submitted the data ';

exit();

}

The result is that the test for a long time did not see the prompt message, think that the code is wrong or the method is wrong, check carefully, in the official document of the results, confirm that there is no error.

Unable to submit the formid. submit(), we temporarily had to change the type of btnSubmit to submit

Enclosing type = "submit"

I did some research on the Internet, and the reasons come down to two:

1. There should be no label with name= "submit" in the form

2. Enctype = "multipart/form-data" cannot be missing from the form.

On test, these two points are absurd and do not solve my problem (maybe my problem environment is different).

Later, I was suggested to change the ID of the registration button to a name instead of submitting. After the correction, the form is submitted normally and the prompt message appears.
