Can’t get value from Summernote textarea using Javascript AJAX send post data

I’ve been checking summernote API, and there is my code

<form id="mail">
  <input type="text" id="email">
  <textarea id="summernote"></textarea>
  <input type="submit">
</form>

$('#summernote').summernote({
  placeholder: 'your Message',
  tabsize: 2,
  height: 300
});

$('document').ready(function() {
  var messageData = $('#summernote').summernote('code');
  var email = $('#email').val();
  $(function() {
    $('#mail').submit(function(event) {
      event.preventDefault();
      $.ajax({
        url: 'sendmail.php',
        type: 'post',
        data: {
          'send_mail': 1,
          'to': email,
          'message': messageData,
        },
        success: function(response) {
          if (response == 'success') {
            //my success response
          } else if (response == 'error') {
            //my error response
          }
        }
      });
    });
  });
});

My problem is the message was successfully sent, but I didn’t get that text area value, just an empty email. Please help.

Note: that I’m using phpMailer for sending email.

Answer

Change the code as below:

1. Initialize the “summernote” inside the ready function.
2. Fetch the summer note value inside the mail submit event

Code as follows:

$('document').ready(function(){

    $('#summernote').summernote({
       placeholder: 'your Message',
       tabsize: 2,
       height: 300
    });


     $(function(){
         $('#mail').submit(function(event){

           var messageData = $('#summernote').summernote('code');
           var email = $('#email').val();

          event.preventDefault();
          $.ajax({ 
           url: 'sendmail.php',
           type: 'post',
           data: { 
            'send_mail' : 1, 
            'to' : email,
            'message' : messageData, 
           }, 
           success: function(response){ 
            if(response == 'success'){ 
            //my success response
             } else if (response == 'error'){
            //my error response
             }
            }
           });
          });
     });
});
