[removed] access variables inside anonymous function from the outside

Question

Say I have this anonymous function:

(function(window){

 var private = \'private msg\';

 function sayit() {
   alert(private) // works
 }

 document.body.on         


        

Answer 1

Ok. I got it.

(function(window){
    var alert_original = window.alert;
    window.alert = function(data) {
        window.extracted = data;
        alert_original(data);
    };
})(window);

(function(window){
    var private = 'private msg';
    function sayit() {
    alert(private) // works
 }
 document.body.onclick = sayit; // works
})(window);

After you click body, you can get 'private msg' from extracted
