Very often, when developing a new site or developing a theme, we see an error “Uncaught TypeError: $ is not a function”, in WordPress it is generally a classic. The problem occurs because WordPress uses the conflict-free jQuery syntax., this means that in the code you need to write instead of the dollar sign $ jQuery text.

1. The first way to solve the problem with “Uncaught TypeError: $ is not a function”

$(window).ready(function() {

Need to write like this:

jQuery(window).ready(function($) {

// code

}

Then inside the code will be executed with a dollar sign, well, or just write jQuery instead of the dollar.

2. The second way to solve the problem with an error “Uncaught TypeError: $ is not a function” and automation solutions for WordPress

Not so long ago I had an idea how not to change everything $ on jQuery and found a very simple solution to this problem. In the functions.php file, you need to add this code and everything else will work fine.

wp_add_inline_script( ‘jquery’, ‘$ = jQuery;’ );

If my solution seemed great to you or you have a better solution, write in the comments I will be glad.
