Javascript 函数数组 [英] Javascript Array of Functions

问题描述

var array_of_functions = [
    first_function('a string'),
    second_function('a string'),
    third_function('a string'),
    forth_function('a string')
]

array_of_functions[0];

这并不像预期的那样工作，因为在创建数组时会执行数组中的每个函数.

That does not work as intended because each function in the array is executed when the array is created.

执行数组中任何函数的正确方法是什么:

What is the proper way of executing any function in the array by doing:

array_of_functions[0];  // or, array_of_functions[1] etc.

谢谢！

推荐答案

var array_of_functions = [
    first_function,
    second_function,
    third_function,
    forth_function
]

然后当你想在数组中执行给定的函数时:

and then when you want to execute a given function in the array:

array_of_functions[0]('a string');
