var functionArray = [$('.img').show, $('.img').hide, $('.img').toggle, $('.img').fadeIn, $('.img').fadeOut, $('.img').fadeToggle];
var buttonArray = [$('.show'), $('.hide'), $('.toggle'), $('.fadein'), $('fadeout'), $('.fadetog')];
var counter = 0;
while (counter < buttonArray.length) {
    buttonArray[counter].click(function () {
        functionArray[counter]();
    })
    counter++;
}

我希望每个按钮都可以对图像执行特定的功能，所以我遍历了类数组和函数数组，但这给了我一个错误：

Uncaught TypeError: functionArray[counter] is not a function
    at HTMLButtonElement.<anonymous> (Script1.js:8)
    at HTMLButtonElement.dispatch (jquery-3.3.1.js:5183)
    at HTMLButtonElement.elemData.handle (jquery-3.3.1.js:4991)

这是怎么了？

使用Jquery
