required attribute is not working in select [duplicate]

I have a html form with input fields that require a value before submission and to achieve this I am using the required attribute in html5 Which is shown in the snippet below with the header Form One.
The problem is I'd like to add a confirm pop-up message after the delete button is clicked -- asking if the user wants to continue.
I have done this in the snippet shown below with the header Form Two but the problem is, the required attribute is not showing when the input field is empty and submitted.
The form gets submitted before the required method is triggered. Anyone has any ideas to solve this html5 incompetence?
THANKS
<h2>Form One </h2>
<form method="post" action="example.com" id="delete_page">
Name : <input type="name" required><br>
<input type="button" value="Cancel">
<input type="submit" value="Delete">
</form>
<hr>
<h2>Form Two </h2>
<form method="post" action="example.com" id="delete_page">
Name : <input type="name" required><br>
<input type="button" value="Cancel">
<input type="submit" onclick="confirm('Are you sure you want to submit')" value="Delete">
</form>

Try using onsubmit on your <form> rather than the button.
<h2>Form Two </h2>
<form method="post" action="example.com" id="delete_page"
onsubmit="return confirm('Are you sure you want to submit?')">
Name : <input type="name" required><br>
<input type="button" value="Cancel">
<input type="submit" value="Delete">
</form>
Browser form validation only kicks in on a submit event.
This will also prevent your form from submitting if the user chooses to "Cancel" the popup.

Form not submitting after disabling submit button

I have an HTML form that has a submit button. I want this button to be disabled when it is clicked. But I also want the form to get submitted.
I am not using ajax request to submit the form. The PHP script that handles the form takes a long time. So some users just click it after a few seconds and the form gets submitted twice which leads to two rows with the same data in the database.
Here's what I tried so far
<form method="POST" action="xyz.php">
<input type="text" name="fields[]" />
<input type="text" name="fields[]" />
<input type="text" name="fields[]" />
<input type="text" name="fields[]" />
<input type="submit" onclick="$(this).attr('disabled', true);" value="Submit" />
</form>
The onclick event on submit button disables the button but it also don't let the form to be submitted. But I want the form to be submitted and also want the button to be disabled.

You May try the below code
onclick="this.disabled=true;this.form.submit();this.value='Submiting...';"

If you're using jQuery, then here's a fully-jQuery, unobtrusively handled version which would work.
If you were to give your form an ID, you could make it handle that form specifically - this example will handle all forms on your page.
$(function() {
$("form").submit(function(event) {
$(this).find('input[type="submit"]').prop("disabled", true);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form method="POST" action="xyz.php">
<input type="text" name="fields[]" />
<input type="text" name="fields[]" />
<input type="text" name="fields[]" />
<input type="text" name="fields[]" />
<input type="submit" value="Submit" />
</form>
Note that you should use .prop() rather than .attr() to set properties such as "disabled"
(see http://api.jquery.com/attr/).

autocomplete='off' does not work in Firefox?

I have an input field <input type='text' name='user' autocomplete='off'> but autocomplete is still active.
This is what I see when I inspect the element
It seems that Firefox somehow thinks that this field is a password field and uses the build-in Login Manager storage module. I did not use any Javascript on this input element.
I also noticed a strange key symbol at the autocomplete drop-down list
How can I get rid of that key symbol and disable autocomplete?
Heres my HTML Code
<form class='clearfix'>
<div id='loginForm'>
<label>
Login
<span>
<a href='/memberArea/lostPass.php' id='hackB'>
Forgot Password? Click here!</a></span>
</label>
<input type='text' name='user' id='username' autocomplete="off">
<label >Password </label>
<input type='password' name='pass' id='passLogin' autocomplete="off">
</div>
<button class='confirmbutton' id='loginButton'>Login</button>
</form>

Clear browser, Try,
<!--
<form autocomplete="off"> will turn off autocomplete for the form in most browsers
except for username/email/password fields
-->
<form autocomplete="off">
<!-- fake fields are a workaround for chrome/opera autofill getting the wrong fields -->
<input id="username" style="display:none" type="text" name="fakeusernameremembered">
<input id="password" style="display:none" type="password" name="fakepasswordremembered">
<!--
<input autocomplete="nope"> turns off autocomplete on many other browsers that don't respect
the form's "off", but not for "password" inputs.
-->
<input id="real-username" type="text" autocomplete="nope">
<!--
<input type="password" autocomplete="new-password" will turn it off for passwords everywhere
-->
<input id="real-password" type="password" autocomplete="new-password">
</form>

why tooltip not display with validation in jquery?

I validate my form using jquery validate .It is working fine .
http://jsfiddle.net/cRew4/2/
When you change focus one field to and another it gives error.
Now I will implement tooltip in that,so I add tittle in all input field as example "title="title"" it show tooltip but it removed validation of that field.Instead of showing error it show title of the input field. why ?
http://jsfiddle.net/cRew4/3/
$("#commentForm").validate();
$(document).tooltip();
<form class="cmxform" id="commentForm" method="get" action="">
<fieldset>
<legend>Please provide your name, email address (won't be published) and a comment</legend>
<p>
<label for="cname">Name (required, at least 2 characters)</label>
<input id="cname" name="name" minlength="2" title="title" type="text" required/>
</p>
<p>
<label for="cemail">E-Mail (required)</label>
<input id="cemail" type="email" name="email" required/>
</p>
<p>
<label for="curl">URL (optional)</label>
<input id="curl" type="url" name="url"/>
</p>
<p>
<label for="ccomment">Your comment (required)</label>
<textarea id="ccomment" name="comment" required></textarea>
</p>
<p>
<input class="submit" type="submit" value="Submit"/>
</p>
</fieldset>
</form>
I need it show tooltip when there is mouse over on the field .but it show validation error when user fill incorrect value intead of tooltip message

The validate takes title by default.
So, you must add ignoreTitle arguement to it.
JS
$(document).tooltip();
$("#commentForm").validate({
ignoreTitle: true
});
The documentation mentions it, look here : http://jqueryvalidation.org/validate/
