why moveBy and moveTo not working in my code?

Question

I think it is an easy questions but I am new in JavaScript

Why buttons \"but3\" and \"but4\" not working when I try moveBy or moveTo a new window?

thanks

Answer 1

The error message says

Permission denied to access property 'moveBy'

To access the properties of another window, it needs to be in the same domain.

Your code works if you replace www.google.com with a file in the same directory.
