Uncaught TypeError: $(...).ready is not a function

Question

Hi I Know this has been asked before but no answer on here seems to help me.

I have this block of JS:

$(document).ready(function() {
    $('.play-icon-hover').hover(function() {
         $('.cms-model-banner-overlay').addClass('.cms-model-banner-overlay-active');
        }, function() {
         $('.cms-model-banner-overlay').removeClass('.cms-model-banner-overlay-active');
    });
});

And I seem to be getting this error but I have no idea why?

Uncaught TypeError: $(...).ready is not a function

Thanks

You are using Prototype.js as well as jQuery.js. If you wanna use jQuery, it is better to encapsulate your code inside an IIFE like this:

(function ($) {
  // jQuery code using $
})(jQuery);

So the solution for your issue is either you change $ to jQuery:

jQuery(document).ready(function() {
  jQuery('.play-icon-hover').hover(function() {
    jQuery('.cms-model-banner-overlay').addClass('.cms-model-banner-overlay-active');
  }, function() {
    jQuery('.cms-model-banner-overlay').removeClass('.cms-model-banner-overlay-active');
  });
});

Or, use a IIFE:

(function ($) {
  $(document).ready(function() {
    $('.play-icon-hover').hover(function() {
      $('.cms-model-banner-overlay').addClass('.cms-model-banner-overlay-active');
    }, function() {
      $('.cms-model-banner-overlay').removeClass('.cms-model-banner-overlay-active');
    });
  });
})(jQuery);
