Question

I have a Javascript function called many times from many pages.

Inside this function I have to check the element which is invoked this function.

I know a method to pass ‘this’ with the function call. I cannot use that method. Because I am working only on a single module.
There are many other modules using this function. So if I change the function definition it will throw error for other modules/pages.

Is there any other way to find the invoked element without passing ‘this’ or without changing the function definition.

Answer 1

Are you sure it will throw an error? It’s perfectly legal to call a javascript function without passing in all the arguments.

Passing in too many arguments is also legal, you access them with the arguments variable.
