在咖啡脚本中调用函数定义的方法

问题描述

你会如何将这段 javascript 代码翻译成 coffeescript?具体来说，我正在努力解决如何在函数定义上调用 .property().

How would you translate this snippet of javascript to coffeescript? Specifically I'm struggling with how to call .property() on the function definition.

MyApp.president = SC.Object.create({
  firstName: "Barack",
  lastName: "Obama",

  fullName: function() {
    return this.get('firstName') + ' ' + this.get('lastName');

    // Call this flag to mark the function as a property
  }.property('firstName', 'lastName')
});

推荐答案

我认为你应该这样写:

MyApp.president = SC.Object.create {
  firstName: "Barack",
  lastName: "Obama",
  fullName: (-> 
    return @get 'firstName' + ' ' + @get 'lastName'
    # Call this flag to mark the function as a property
  ).property('firstName', 'lastName')
}
