Hello to all
I need coding to create confirm alert message when user clicks a browser close button..........

Javascript coding is more helpful to me....

Can anyone help me.

try this

window.onunload = function () {
           var r = confirm( "Press a button!" )
           if ( r == true ) {
               alert( "You pressed OK!" )
           else {
               alert( "You pressed Cancel!" )
