Error D.ajax is undefined

Seems to be:

drupal_add_js('misc/ajax.js');

When this is included, I get the error. When not there, no error.

jQuery 1.8.

Hmm...

Wrapped the contents of jquery_update.js like this:

jQuery(document).ready(function() { 

(function (D) {
  var beforeSerialize = D.ajax.prototype.beforeSerialize;
  D.ajax.prototype.beforeSerialize = function (element, options) {
    beforeSerialize.call(this, element, options);
    options.data['ajax_page_state[jquery_version]'] = D.settings.ajaxPageState.jquery_version;
  }
})(Drupal);

});

Delays code execution until after Drupal is defined.

No error message. The JS code was executed (set a breakpoint to find out). Whether it has the intended effect, I don't know.

Here is patch to fix this problem based off the solution mathieso provided.

For pages with complex js this could slow down rendering so ideally we would find out why the ajax property doesn't exist at when the code is called but I think this is decent enough solution in the short term.

maybe I'm wrong
but at this point in the design bug fixes

IMHO this is design error.

drupal.ajax is set dependent on jquery_update.ajax.fix by JQuery Update:

$javascript['drupal.ajax']['dependencies'][] = array('jquery_update', 'jquery_update.ajax.fix');

which makes jquery_update.js to load BEFORE ajax.js — i.e. before Drupal.ajax becomes declared.

This must be resolved as it breaks things.

Hi I'm getting a site wide ajax error on fields in the backend.

I've disabled the Jquery update module and still getting that error.

Not sure where to go from here. Anyone able to shed some light?

Thanks ;)

version

Sorry, comments from #6 and #7 are invalid. They should be edited or removed.

Looks like something is breaking load sequence. In my situation (invalid comments #6 and #7) the reason was REL module, which simply did drupal_add_js('misc/ajax.js'); and this was breaking weight of already prepared ajax.js library.

I too get this problem when using Commerce Ajax Cart (https://drupal.org/project/commerce_ajax_cart). When I disable that module the error disappear.

The patch in #3 works for me though. So thanks! /Mats

Patch # 3 worked for me, at least in the interim. The error was causing my subsequent scripts to hang.

Confirming #13!

Set the priority to major because it breaks functionality on a wide range and seems to be a design bug. Hope you agree.

Hmm, This looks like it was introduce when we added the option to use different versions of jquery for admin pages.

Can someone confirm this is an issue if you're only using one version of jQuery, or is this happening always even if you don't use a different version for admin pages.

It happens with all version of jquery for me
patch in #3 fixed the problem

Yea, this patch doesn't look right, this is definitely a design error, This file should be loaded after drupal ajax not before it.

The proper fix for this would probably be removing the jquery_update.ajax.fix library and instead adding that file into the drupal.ajax_library after the ajax.js file.

This way it's always included right after it.

If someone is interested if not it'll have a patch later tonight.

Any news on the patch? Also using Commerce Ajax cart and have the same issue. Should this be moved there?

bug in Commerce Ajax cart

@ericduran I tried to give that a shot but failed miserably :( Can't stand the render array API...

Here's the patch just in-case it's half way there for you...

i think #20 means something like the attached patch...
for me it is only broken in IE8 and the attached patch does not fix it

(See screenshot)

I show that IE complains about ajax.js..so i went in line 625..and changed new to newz just to see what happens..i refreshed the page and the error was gone...

so maybe this is a drupal core bug? since this line was introduced in drupal 7.27 and http://drupalcode.org/project/drupal.git/commit/6642fbc

indeed

this is definitely a commerce_ajax_cart issue. If I install it ajax just breaks. Too bad.

I'll leave it to better minds than mine to switch the issue to that queue.

commerce_ajax_cart issue solution (not yet committed): https://www.drupal.org/node/2280465

@maxilein Does the latest patch there solve the problem, if so I'll commit it. It needs review/rtbc.

@joelpittet it solves the problem of the commerce_ajax_cart breaking jquery_update for rules. Yes.

Rerolled #24 but it does not work for me, I still get the same error message in console. I don't have commerce_ajax_cart.

@czigor
bug in Commerce Ajax cart

drupal_add_js('misc/ajax.js'); //WTF?
drupal_add_library('system', 'drupal.ajax'); //good

I still have this bug.

> I still have this bug.

So what?

when I use commerce_ajax_cart, I have bug
I replace stupid code in commerce_ajax_cart_preprocess_html

  drupal_add_js('misc/ajax.js',array('type' => 'file' , 'weight' => -100 ));

on

  drupal_add_library('system', 'drupal.ajax');

and I feel good

drupal.ajax - is library, not single js

But I can't do that since I don't have commerce_ajax_cart and still have this bug.

@czigor Which modules do you have installed? Could you look for this in your code? Maybe another module is doing something similar.

drupal_add_js('misc/ajax.js'

It seems that one of our custom modules had the same drupal_add_js. Changing it to drupal_add_library solved the problem. Thanks!

Line #34 works for me.
