Events Manager 5.5.2 error: TypeError: $(…).on is not a function

    Hi there.

    EM 5.5.1 was working great for us in WP 3.7, but since upgrading to 5.5.2 2 days ago, we are getting a JS error and our website’s slider is no longer working.

    The error we’re getting on the page is “TypeError: $(…).on is not a function, from line 163 of events-manager.js” and the full code on that line is:

    $('#event-form #event-image-delete, #location-form #location-image-delete').on('click', function(){

    We updated to WP 3.7.1 and are still having this issue.

    Any thoughts? The site is https://greatlakesphragmites.net . Many thanks!

  • Hi,

    This sounds like a Javascript conflict caused by jQuery being loaded incorrectly by a theme or plugin.

    If you switch to the default theme and deactivate all other plugins except for Events Manager and your slider plugin, does the problem disappear?

    Hey, Caimin_nwl –

    It looks like it’s an issue with the theme using outdated syntax for an integrated jquery plugin it’s using for its slider. Worked fine without errors until the new EM, weirdly.

    Thanks!

    in your theme functions.js – maybe you can try to change $(document).ready(function() { to jQuery(document).ready(function() {

    Hi, Angelo–it was worth a shot, but there are still many functions both in functions.php and the slider.php files referencing $(‘#slideshow’), $(‘#cycle’), etc. I’ll ask our js guy if he can take a swing at more updated syntax for these.

    Thanks!

    hi,

    just change this line -> $(document).ready(function() {

    Hey, Angelo–it didn’t work by itself, but changing all of the $ references to jQuery in both the js in functions.php and functions.js worked! Your suggestion tipped me off to finding this helpful info on the issue: https://www.pauljoyceuk.com/codex/2011/jquery-is-not-a-function/

    Many thanks!

    glad it’s working now.
