I'm trying to invoke addEventListener() using apply() method. The code is like:
function rewrite(old){ return function(){ console.log( 'add something to ' + old.name ); old.apply(this, arguments); } } addEventListener=rewrite(addEventListener);
It doesn't work. The code works for normal JavaScript method, for example,
function hello_1(){ console.log("hello world 1!"); } hello_1=rewrite(hello_1);
Need help!
Thanks!
