apply(Enum,:reverse,[[1,2,3]])

一个例子：

使用这样的模块：

defmodule Apply do
  def dynamic(method_name,params) do
    apply(Apply,method_name,params)
  end

  def method1(params) do
    IO.puts "Method 1,called by " <> params
  end

  def method2(params) do
    IO.puts "Method 2,called by " <> params
  end
end

我可以使用它的名称来调用特定的函数：

iex(1)> c("apply.ex")
[Apply]

iex(2)> Apply.dynamic(:method1,["Hey"])
Method 1,called by Hey
:ok

iex(3)> Apply.dynamic(:method2,["Hey"])
Method 2,called by Hey
:ok
