jQuery code, not understanding

I am looking at this code and as I'm new to web design I'm unable to understand it.

So on my index page I have a link to google and the ext.js page the following code.

This is what I understand which is wrong.

The user clicks ok or cancel, therefore the variable c is either ok or cancel. Now I don't see the point of the if statement, because it will be either ok or cancel on other words true or false.

$(window).unload(function(){
    var c = confirm('Are you sure you want to leave?');
    if(c){ 
        return true;
    }else{
        return false;
    }
});

No, it will be true or false depending on which of OK or Cancel (or whatever the local i18ned version is for the browser in question) was pressed.

i dont seee the point of the if statement

There isn't a point to it.

return confirm('Are you sure you want to leave?');

… gives the same result, much more concisely.
