vue子组件向父组件传值问题记录

Event "titlechanged" is emitted in component <Login> but the handler is registered for "titleChanged". Note that HTML attributes are case-insensitive and you cannot use v-on to listen to camelCase events when using in-DOM templates. You should probably use "title-changed" instead of "titleChanged".
