I am working on a new feedback form for my site. I have the basics working fine, the form can be submitted and the data is handled just the way its supposed to. I'm looking to make it so a name and the feedback is required but the email is not. I would also like to add a human check to this. I'm moving over from php and had a remove the text as my human check. Last question, is this the best way to be doing this?

2. <script src="http://code.jquery.com/jquery-latest.js"></script>
3. <script type='text/javascript'>
4. $(function() {
5.     $('#feedbackgiven').submit(function(event) {
6.            event.preventDefault()
7.            
8.           var name1 = $('#feedbackgiven [name="name"]').val();
9. var email1 = $('#feedbackgiven [name="email"]').val();
10. var feedback_1 = $('#feedbackgiven [name="feedback"]').val();
11.            $.ajax({type: 'POST', url: 'submit-feedback.php', cache: false, timeout: 10000,
12.                  data: {name_sub: name1, email_sub: email1, feedback_sub:feedback_1},
13.                  success: function() {
14.                        alert('Your feedback has been recived');
15.                  },
16.                  error: function() {
17.                        alert('There was a problom');
18.                  },
19.            });
20.      });
21. });
22. 
    
23. </script>
25. <span>Send us your feedback</span>
