[ovirt-devel] 回复： In windows OS & firefox brower, Window.Location.replace(url) would stop System to execute Command, and would not catch any error info.But other OS like firefox in linux would not happen like that

[Vojtech Szocs]

Hi,

another way to solve this, without modifying oVirt WebAdmin sources,
is to write a small UI plugin that performs the redirect within its
UserLogout callback:

  var api = parent.pluginApi('ExampleRedirectOnLogoutPlugin');
  api.register({
    UserLogout: function() { window.location.assign('http://www.example.org'); }
  });
  api.ready();

Reference documentation: http://www.ovirt.org/Features/UIPlugins

Regards,
Vojtech
