I keep encountering the error
Uncaught TypeError: Function.prototype.apply: Arguments list has wrong type.apply() method but I'm unable to pinpoint the cause. You can review my code here.
Upon loading jsfiddle, try clicking next to the word "test" and pressing the Enter key. The error seems to be originating from the this.addEvent method. I am attempting to designate my object as the 'this' within the callback function of the event.
It is recommended to utilize the .call method instead of .apply.
The a.apply(obj, lst) function is essentially the same as a(lst[0], lst[1], lst[2], ...) when lst is an Array (or arguments) and uses obj as the context.
On the other hand, a.call(obj, x, y, z, ...) is the equivalent of a(x, y, z, ...) while utilizing obj as the context.
Since e is just one argument and not an array of arguments, the best approach is to use .call.
apply requires an array object. If you prefer to provide arguments directly, you can use call. Another option is to convert arguments to an array before using apply
func.apply(editorObject, [e]); //=> apply needs an array of arguments
func.call(editorObject, e); //=> call accepts arguments directly
