发送和 sendAction 街道，可以说，你可以发送一个推迟的动作，并期望它解决/拒绝它。

send and sendAction are one way streets, that being said, you can send a defer to the action and expect it to resolve/reject it.

var defer = Ember.RSVP.defer();

defer.promise.then(function(resolvedValue){
  alert(resolvedValue); 
});

setTimeout(function(){
  defer.resolve('hello world');
},2000);

你的样子看起来有点像这样

Yours would look a bit like this

var defer = Ember.RSVP.defer(),
    self = this;

defer.promise.then(function(){
  self.closeModal();
},
function(){
  alert('error');
});

this.sendAction('save', defer);

保存操作

actions: {
  save: function(defer){

    // if succeeded 
    defer.resolve();

    // or if failure occurs 
    defer.reject();
  }
}

小心，你想确保你不要不要剔除拒绝的路线，你会讨厌在这里停留模式，因为保存失败，没有失败的方法。

Be careful, you want to make sure you don't leave out the reject route, you'd hate to have the modal stuck up there because the save failed and there wasn't a failure method.

对不起我没有t转换成咖啡脚本，我想你会理解或转换和理解，我不会给你一个错误的答案。

Sorry I didn't convert to coffee script, I figure you'll either understand or convert and understand and I won't have given you a wrong answer.
