Uncaught ReferenceError: jQuery is not defined

Hi,

thanks for your post, and sorry for the trouble.

That’s strange, as the jQuery file is indeed loaded… Can you please turn off the jQuery Migrate Helper plugin, so that I can see the problem without this being on?

I appreciate such a timely followup. I just deactivated and then deleted jQuery Migrate Helper plugin.

Update as of Fri. 01Jan2020 12:20pm ET USA:

After I deactivated all plugins and cleared cache and then tested tablepress, the same error in the console was generated.

The website’s theme is Astra – pro – child theme and I believe it has had some custom code put into a child functions.php file, not sure whether that could be interfering with tablepress.

Also, this is the other info about the setup that I overlooked providing in my initial inquiry:

Hi,

I just noticed that the jQuery library is loaded with the defer='defer' attribute, to delay the loading of the JS file.
This is non-standard behavior in WordPress, so that your theme or another plugin is adding this. It’s however causing this problem.
Can you please check what’s adding this and then turn that off?

Thank you for identifying the problem. I will take some time to figure out where the defer='defer' is being added and then remove it. I’ll mark this support request as resolved, too.

Hi,

it’s likely a plugin or your theme, so I would start looking there. For a test, you could temporarily deactivate plugins or switch the theme.

I looked into the theme, which is using a child theme. In the child theme folder, I reviewed the functions.php file and it had some code in it to defer javascript. So, I removed it and tablePress works perfectly with all the dynamic features.

Anyway, here’s the snippet of code that I removed:

// Defer Parsing of JavaScript in WordPress via functions.php file
// Learn more at https://technumero.com/defer-parsing-of-javascript/ 

function defer_parsing_js($url) {
//Add the files to exclude from defer. Add jquery.js by default
    $exclude_files = array('jquery.js');
//Bypass JS defer for logged in users
    if (!is_user_logged_in()) {
        if (false === strpos($url, '.js')) {
            return $url;
        }

        foreach ($exclude_files as $file) {
            if (strpos($url, $file)) {
                return $url;
            }
        }
    } else {
        return $url;
    }
    return "$url' defer='defer";

}
add_filter('clean_url', 'defer_parsing_js', 11, 1);

Thanks again for your guidance and solution.

Hi,

yes, that’s indeed it! ?? Nice find!
Good to hear that everything is working again!

Best wishes,
Tobias

P.S.: In case you haven’t, please rate TablePress here in the plugin directory. Thanks!
