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>

<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>
