javascript - Post preview - Passing data with AJAX and Fancybox

I'm trying to do a post preview, which will appears in a new Fancybox iframe. Since couple of weeks I'm looking for some help or best practices, but I can't find it.

My main problem is to pass the data from form (before updating database) to Fancybox window. My AJAX skills are very poor, so maybe my problem isn't so hard.

Please check the code:

$('.preview2').fancybox({
fitToView    : false,
width        : 905,
height        : 505,
autoSize    : false,
closeClick    : false,
openEffect    : 'none',
closeEffect    : 'none',
ajax: {
    type: "POST",
    cache : false,
    url: "preview.php",
    data: $('#postp').serialize()
}
});

And a calling link:

<a class="preview2" data-fancybox-type="iframe" href="preview.php" id="preview2">Preview</a>

I'm almost sure everything is fine with preview.php file, just posting the variables and printing it in right places.

Can someone check Fancybox / AJAX part?

As I mentioned in my comments, your preview button should submit the form via ajax to get the POST preview values (we'll use ajax instead of iframe) so :

<a class="preview2" data-fancybox-type="ajax" href="preview.php" id="preview2">Preview</a>

Then you would need to bind the preview button to a manual on("click") method to submit the form via ajax firstly ....and then post the results in fancybox secondly like :

$(document).ready(function () {
  $('.preview2').on("click", function (e) {
    e.preventDefault(); // avoids calling preview.php
    $.ajax({
      type: "POST",
      cache: false,
      url: this.href, // preview.php
      data: $("#postp").serializeArray(), // all form fields
      success: function (data) {
        // on success, post (preview) returned data in fancybox
        $.fancybox(data, {
          // fancybox API options
          fitToView: false,
          width: 905,
          height: 505,
          autoSize: false,
          closeClick: false,
          openEffect: 'none',
          closeEffect: 'none'
        }); // fancybox
      } // success
    }); // ajax
  }); // on
}); // ready
