How to confirm window closing

[Amadey]

Greetings,

I'm noob in JS and Ext. My first js 'hello world' was yesterday...

Well. The idea was to ask user if he really want to close window. The result is:

function confirm_close()
{
Ext.Msg.confirm('Ужас','Ты действительно меня бросаешь?',
function(answer){
if (answer == 'yes'){
     ras4window.destroy();
}
}
 );
}  function window_on_create(){
ras4window=Ext.create('Ext.window.Window', {
title: 'Привет',
height: 200,
width: 400,
layout: 'fit',
listeners:{  
beforeclose: function() {
confirm_close();
return false;
}
},
items: { 
}
 }).show();

Is there any better ways of doing this?

P.s. my english is bad. sorry.

That looks pretty good. I would probably organize the code differently, but the concept of returning false from beforeclose and showing a confirm dialog is correct.
