fast fail if nothing selected (http:angosso.net/X11/jquery.js)

hook for manipulating the form data before it is extracted;

convenient for use with rich editors like tinyMCE or FCKEditor

var veto = {};

this.trigger('form-pre-serialize', [this, options, videos]);

if (videos.videos) {

log('ajaxSubmit: submit videos via form-pre-serialize trigger');

provide opportunity to alter form data before it is serialized

give pre-submit callback an opportunity to abort the submit

if (options.beforeSubmit && options.beforeSubmit(a, this, options) === false) {

log('ajaxSubmit: submit aborted via beforeSubmit callback');

return this;

fire vetoable 'validate' event

perform a load on the target only if dataType is not provided

var fn = options.replaceTarget ? 'replaceWith' : 'html';

are there files to upload?

var fileInputs = $('input:file', this).length > 0;

var mp = 'multipart/form-data';

var multipart = ($form.attr('enctype') == mp || $form.attr('encoding') == mp);

options.iframe allows user to force iframe mode

25-Dec-12: now defaulting to iframe mode if file input is detected

if (options.iframe !== false && (fileInputs || options.iframe || multipart)) {

hack to fix Safari hang (thanks to Tim Molendijk for this)

take a breath so that pending repaints get some cpu time before the upload starts

function doSubmit() {

make sure form attrs are set

update form attrs in IE friendly way

support timout

add iframe to doc and submit the form

/**

  • ajaxForm() provides a mechanism for fully automating form submission.

*

  • The advantages of using this method instead of ajaxSubmit() are:

*

  • 1: This method will include coordinates for <input type="image" /> elements (if the element

* is used to submit the form).

  • 2. This method will include the submit element's name/value data (for the element that was

* used to submit the form).

  • 3. This method binds the submit() method to the form for you.

*

  • The options argument for ajaxForm works exactly as it does for ajaxSubmit. ajaxForm merely
  • passes the options argument along after properly binding events for submit elements and
  • the form itself.
