EmberJS 路由器从拒绝中恢复
2018-01-04 13:39 更新
描述
你也可以在模型钩子中捕获promise,这样就不会停止正常的转换执行。
语句
Ember.Route.extend({ model: function() { //return the recovery message } });
例子
<!DOCTYPE html> <html> <head> <title>Emberjs Recovering from Rejection</title> <!-- CDN's --> <script src="https://cdnjs.cloudflare.com/ajax/libs/handlebars.js/3.0.1/handlebars.min.js"></script> <script src="https://code.jquery.com/jquery-2.1.3.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/ember.js/1.10.0/ember.min.js"></script> <script src="https://builds.emberjs.com/tags/v1.10.0-beta.3/ember-template-compiler.js"></script> <script src="https://builds.emberjs.com/release/ember.debug.js"></script> <script src="https://builds.emberjs.com/beta/ember-data.js"></script> </head> <body> <script type="text/x-handlebars"> {{outlet}} </script> <script type="text/x-handlebars" data-template-name="index"> <!-- display the message --> <h3>{{model.msg}}</h3> </script> <script type="text/javascript"> App = Ember.Application.create(); App.IndexRoute = Ember.Route.extend({ //using the route's model to continue on with the transition model: function() { //returning recovery messages return { msg: "Recovered from rejected promise" }; } }); </script> </body> </html>
