javascript - 将函数作为参数传递

Question

我有两个函数，将其中一个作为参数传递，例如:

var a = function(f)
{
  // some code
  f();
};

var b = function()
{
};

a(b); // works great, the function a is executed, then the function b is executed

现在我需要将其扩展到树函数，例如:

var a = function(f)
{
  // some code
  f();
};

var b = function(f)
{
  // some code
  f();
};

var c = function()
{
};

a(b(c)); // but it does not work. b(c) words like a method and get executed right on the instruction.

我怎样才能做到这一点？

Answer 1

传递一个执行b(c)的包装函数:

a(function() {
    b(c);
});
