    Default Ext.EventManager "beforeunload" - Issue on FF

    Ext.EventManager "beforeunload" - Issue on FF


    Hello,

    I am using below code in ExtJS version 4.2.1.883.

    Code:
    Ext.EventManager.on(window, 'beforeunload', function () { alert("1")})

    When I call it in FF, it throws error in console
    ns_error_not_available

    Any help?

    I couldn't find any reports of this error with 4.2.1. In which version of Firefox are you seeing this?

    Thanks. I'm not seeing it in Firefox 36. Can you post a test case which displays the behavior?

    @Gary:

    There is no specific code. I just used below code and it throws exception.
    Code:
    Ext.EventManager.on(window, 'beforeunload', function () { alert("1")})
    Is there any possibility of FF plugin/setting? If so any solution?

    I see it now. I'll move this to the Bugs forum so it can get looked at.

    This isn't a bug, the browser is preventing you from doing it.
