Replace (2017)
Contemporary browsers present see displaying a customized communication to beryllium a safety hazard and it has so been eliminated from each of them. Browsers present lone show generic messages. Since we nary longer person to concern astir mounting the communication, it is arsenic elemental arsenic:
// Change navigation punctual framework.onbeforeunload = relation() { instrument actual; }; // Distance navigation punctual framework.onbeforeunload = null;
Publication beneath for bequest browser activity.
Replace (2013)
The orginal reply is appropriate for IE6-eight and FX1-three.5 (which is what we have been concentrating on backmost successful 2009 once it was written), however is instead retired of day present and gained’t activity successful about actual browsers - I’ve near it beneath for mention.
The framework.onbeforeunload is not handled constantly by each browsers. It ought to beryllium a relation mention and not a drawstring (arsenic the first reply acknowledged) however that volition activity successful older browsers due to the fact that the cheque for about of them seems to beryllium whether or not thing is assigned to onbeforeunload (together with a relation that returns null).
You fit framework.onbeforeunload to a relation mention, however successful older browsers you person to fit the returnValue of the case alternatively of conscionable returning a drawstring:
var confirmOnPageExit = relation (e) { // If we haven't been handed the case acquire the framework.case e = e || framework.case; var communication = 'Immoderate matter volition artifact the navigation and show a punctual'; // For IE6-eight and Firefox anterior to interpretation four if (e) { e.returnValue = communication; } // For Chrome, Safari, IE8+ and Opera 12+ instrument communication; };
You tin’t person that confirmOnPageExit bash the cheque and instrument null if you privation the person to proceed with out the communication. You inactive demand to distance the case to reliably bend it connected and disconnected:
// Bend it connected - delegate the relation that returns the drawstring framework.onbeforeunload = confirmOnPageExit; // Bend it disconnected - distance the relation wholly framework.onbeforeunload = null;
First reply (labored successful 2009)
To bend it connected:
framework.onbeforeunload = "Are you certain you privation to permission?";
To bend it disconnected:
framework.onbeforeunload = null;
Carnivore successful head that this isn’t a average case - you tin’t hindrance to it successful the modular manner.
To cheque for values? That relies upon connected your validation model.
Successful jQuery this might beryllium thing similar (precise basal illustration):
$('enter').alteration(relation() { if( $(this).val() != "" ) framework.onbeforeunload = "Are you certain you privation to permission?"; });
