Uncaught ReferenceError: function is not defined with onclick

Question

I\'m trying to make a userscript for a website to add custom emotes. However, I\'ve been getting a lot of errors.

Here is the function:

fun         


        

Answer 1

If the function is not defined when using that function in html, such as onclick = ‘function () ', it means function is in a callback, in my case is 'DOMContentLoaded'.
