javascript - 连接 Javascript 函数和字符串

Question

我试图将函数返回的结果连接到一个简单的字符串，两者都在同一个对象内声明。示例:

var hello = {
  how: function(){
    return ' are you';
  },
    ans: 'how',
    answer: 'how' + this.how() 
};

console.log(hello.how()); //works
console.log(hello.ans); //works
console.log(hello.answer); //doesnt work

这是Fiddle

感谢您的帮助!

Answer 1

您可以使用构造函数来创建对象，如下所示:

var hello = new function() {
  this.how = function(){
     return ' are you';
  },
  this.ans = 'how',
  this.answer = 'how' + this.how() 
};

console.log(hello.how()); //works
console.log(hello.ans); //works
console.log(hello.answer); //doesnt work
