Question

I want to execute some code when user close their browser. I found some piece of code and try it, but it is not working. I notice that it is working when I am clicking on Run link at jsfiddle. I dont know why.

$(function(){
$(window).on('beforeunload', function(){
    alert(0)    
})  
})

Fiddle

when the beforeunload event is triggered generates an default alert

$(function(){
$(window).on('beforeunload', function(){   
 return 'message';
 });  
});

you can override the message like the above code sample
