您可以聲明一個變量，它將保存this的引用，可用於後者。

app.service('myservice', function() { 
    //Declare a varible to hold reference 
    var _this = this; 
    this.messages = []; 
    this.myfunction1 = function() { 
     //Stuff 
     function myfunction2() { 
      //Use the reference variable 
      console.log(_this.messages) 
     } 
    } 
});
