Status Change Events

 $scope  . $on ( ' $ Statechangestart ' function ) { //If you need to block the completion of the event            

event. preventdefault();   

});

   < Span class= "token punctuation" > parameters:          

event：该事件的基本信息

toState:我们可以得到当前路由的信息，比如路由名称，url,视图的控制器，模板路径等等

toParams:We can get the parameters of the current route

fromState：We can get information on the last route, such as the route name, URL, view controller, template path, etc.

fromParams：We can get the parameters of the previous route

The events that can be triggered include:

Statechangestart

Triggered when the state change is started

$stateChangeSuccess

Triggered when the status change is successful

$stateChangeError

When a state change encounters an error, the error is usually that the target cannot be loaded, the pre-loaded data cannot be loaded, and so on.

According to the above: the user is not logged in the case, jump to the routing main.mywork, should be redirected to the login page. But found jumps.
After several twists and turns, found himself too careless. Not introduced

The ' ui.router.state.events ' module, index.html page also did not introduce a response to the stateevents.js.
