how to disable close button in window

Question

Riyaz Akhtar · Answer

you cannot disable the window's close button but you can ask confirmation before closing the window . try below code window.onbeforeunload = function (e) { e = e || window.event; // For IE and Firefox prior to version 4 if (e) { e.returnValue = 'Sure?'; } // For Safari return 'Sure?'; };

Hi yadagiri, use this Java Script: window.onbeforeunload = function(){ return 'Do you want to leave ?';} You cannot disable the close button but you can prompt a user if one really wants to leave. Happy Coding :)
