推荐答案

您可以通过使用钩子来实现所需的行为.

You can achieve the behavior you want by using hooks.

// onStop hook is executed whenever we LEAVE a route
Router.onStop(function(){
  // register the previous route location in a session variable
  Session.set("previousLocationPath",this.location.path);
});

// onBeforeAction is executed before actually going to a new route
Router.onBeforeAction(function(){
  // fetch the previous route
  var previousLocationPath=Session.get("previousLocationPath");
  // if we're coming from the home route, redirect to contact
  // this is silly, just an example
  if(previousLocationPath=="/"){
    this.redirect("contact");
  }
  // else continue to the regular route we were heading to
  this.next();
});

这是使用iron:router@1.0.0-pre1
