Hi Sean,

I think that is exactly the error that cut me off, when I upgraded from 8.0.38 to 8.1 AND I STILL HAVE THIS ERROR TILL NOW (Thought about not use anymore jQuery due to this, but a lots of components we are using are based on jQuery)

I mean all my code was working like a charm,

Once I upgraded to 8.1, I got errors everywhere I used Select2 in my Modal on ajax, and since Select2 is jQuery dependent, I got that error of "Uncaught ReferenceError: $ is not defined"

Now I got the issue ,

thank also to user BüÅŸra (OP), to bring that up,

But how to from now on to use run my code on document ready event ?????

I wen as you refering to go to you custom js scripts under src/sass/. as you said above but didn't find nothing !!!

But instead I sneak up on your js code and found something useful, is this the code you are refering too (I took example of a KTImage):


// On document ready
if (document.readyState === 'loading') {
document.addEventListener('DOMContentLoaded', KTImageInput.init);
} else {
KTImageInput.init();
}


If so, please advice, bair with me witness with this one please .

NB : Thins is not just an issue for me, it's the whole Web project we are building that rely on, please advice.

Thank you Sean for everything, wait for you simple and accurate explanation (As JS is not my strength point)

Thank you.

I have file application.html.haml

I render other pages in this file with ruby ​​specific code.
but jquery doesn't work on the pages I include in it.

so it seems to work only on the typed page.
It doesn't work on pages rendered on that page.


I don't understand your solution, what should I do? js files seem to be loaded successfully on the page.
