Drupal.ajax is undefined

I'm pretty sure this is fixed in the 7.x version.

Seems like is still a bug. It should be noted, you need to enabled ajax in the views module in order for this to work.

Without it it throws the error, but I think it might be better to keep throwing the error so is obvious that views doesn't have Ajax enabled.

@agalitsyn it is type ajax/non-ajax. That being said using the views_load_more pager without ajax wouldn't be very good since the behavior would be that of a regular pager. It wouldn't be very performant to keep making the sql query render more and more data in a single call.

That being said this ajax error should still be fixed.

Also the idea behind non-ajax support is for when a user doesn't have JS enbled, the pager would still work as expected instead of not doing anything.

Proposed patch to avoid to declare viewsLoadMoreAppend function if Drupal.Ajax is not available. Error with JavaScript aggregation.

Tested with js aggregated and without aggregation

this works for me too

I had a similar js aggregation/ajax problem in a custom module. Solved it by using:

/**
 * Implements hook_preprocess_html()
 */
function MYMODULE_preprocess_html() {
  drupal_add_library('system', 'drupal.ajax');
}

This way, ajax is included AND aggregation is fine. Before, I had it in hook_init or hook_node_view but that doesn't work. I think the js aggregator handles libraries differentyl in bundles.

Neither of these fixes are correct for this module.

I'll just put up a patch soon to fix this issue. That being said this is only an issue if you're using it wrong. If you don't have ajax enable then the module isn't going to work as expected.

But yes this should be fixed.

To keep it within the module, I added the library in the theme function.

function theme_views_load_more_pager($vars) {
  global $pager_page_array, $pager_total;  

  drupal_add_library('system', 'drupal.ajax'); // added this line here
  drupal_add_js(drupal_get_path('module', 'views_load_more').'/views_load_more.js');

This seems to fix the issue for me.

#9 eridduran, on the homepage it says the following: "Provide ajax/no-ajax views load more".

So shouldn't the module work even if the view is not ajax enabled?

Attached patch to avoid undefined ajax error. views_load_more.js is only included if ajax is enabled.

This looks like a pretty simple fix

Patch #12 commited to 7.x-1.x-dev.
http://drupalcode.org/project/views_load_more.git/commit/a3f8362

Hello,

I used the version 7.x-1.2 of Views Load More and i have the same error ( with firebug). The patch of #12 it's already in the code. Many people have this problem ?

EDIT : if the line 16 var targetList = response.targetList || ''; is comment this resolve the error but is not a good solution
Sorry if my english it's bad.

Cordially

Looks like this was resolved and commited.

@K_Gonzalez if your still having an issue. Please detail it including steps to reproduce in a new issue.

You probably want to have a look at #2721591: Drupal.ajax is undefined and see if the same issue would apply to views_load_more and/or if the improved condition will be beneficial.
