javascript - CoffeeScript 循环方法

Question

我有一个对象文字，用于对方法进行分组。我希望能够轻松调用一整组方法，如下所示:

group =
  methodA: (str) ->
    console.log str + "from method A"

  methodB: (str) ->
    console.log str + "from method B"

for method in group
  method "hello"

# should log to console:
# "hello from method A"
# "hello from method B"

当我尝试这个时，它似乎不起作用。我缺少什么/你应该如何循环访问这样的一组方法？

Answer 1

for ... in 编译为 for 循环，假设您正在循环数组 - 使用 for own ... of 相反:

group =
  methodA: (str) ->
    console.log str + "from method A"

  methodB: (str) ->
    console.log str + "from method B"

for own method of group
  group[method] "hello"
