使用e.preventDefault（）联系表单; 不工作

Question

UPDATE - the contact form is found at this URL.

I am trying to get the following contact form to function, using this tutorial.

I manage to get everything to work as expected on my computer using apache webserver. After uploading the files to an online website, the ajax function does not kick in. I seems like the e.preventDefault(); stops working after the upload, and the form is redirected to a new site,and not just being processed on the site without the reload.

I have also been trying to use the return false; instead of e.preventDefault(); without any success.

Her is my code:

.html

<form method="post" action='mail/mail.php'>
    <label>Name</label>
    <input name="name" id="name" placeholder="Name.." required="true" class="input-field">

    <label>Mail</label>
    <input type="email" name="email" placeholder="Mail.." required="true" class="input-field">

    <label>Msg</label>
    <textarea name="message" id="message" class="textarea-field" required="true"></textarea>

    <input type="submit" id="submit" name="submit" value="Send">
</form>

    <div id="loading">
        Sender melding...
    </div>
    <div id="success">
    </div>

.js

$(function(){
      $('form').submit(function(e){
        var thisForm = $(this);
        //Prevent the default form action

        //return false;
        e.preventDefault();

        //Hide the form
        $(this).fadeOut(function(){
          //Display the "loading" message
          $("#loading").fadeIn(function(){
            //Post the form to the send script
            $.ajax({
              type: 'POST',
              url: thisForm.attr("action"),
              data: thisForm.serialize(),
              //Wait for a successful response
              success: function(data){
                //Hide the "loading" message
                $("#loading").fadeOut(function(){
                  //Display the "success" message
                  $("#success").text(data).fadeIn();
              });
            }
          });
        });
      });
    })

Please help!

That's because your JS is missing a closing });. Please check this demo to confirm that the default action is indeed prevented and the ajax does kick in. However, I was expecting a POST but instead I am seeing an OPTIONS request.

NOTE: Giving an element a name or id attribute value of submit is bad practice. You cannot for example use JavaScript to submit the form via default form submission -- this.submit() or $('form')[0].submit() without getting the error ...submit() is not a function .....

$(function() {
      $('form').submit(function(e) {
        var thisForm = $(this);
        //Prevent the default form action

        //return false;
        e.preventDefault();

        //Hide the form
        $(this).fadeOut(function() {
          //Display the "loading" message
          $("#loading").fadeIn(function() {
            //Post the form to the send script
            $.ajax({
              type: 'POST',
              url: thisForm.attr("action"),
              data: thisForm.serialize(),
              //Wait for a successful response
              success: function(data) {
                //Hide the "loading" message
                $("#loading").fadeOut(function() {
                  //Display the "success" message
                  $("#success").text(data).fadeIn();
                });
              }
            });
          });
        });
      });
  }); // <==== MISSING THIS
