Bug #: 33566
Summary: WikiEditor's beforeunload logic should be rewritten to
play nicely with other handlers
Product: MediaWiki extensions
Version: any
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: WikiEditor
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
This is a followup to bug 33497.
On further consultation with some JavaScript developers, WikiEditor seems to be
doing its beforeunload handler incorrectly, or at least not optimally. The
style of:
window.onbeforeunload = function() {
return something();
};
assumes there is only one such handler on beforeunload, and will clash with
other beforeunload handlers in extensions, such as this style:
$(window)
.bind('beforeunload', myFunc);
WikiEditor's logic should be rewritten to play nicely with other handlers.
