一步一步跟着老师写完的，怎么就一直效果和老师的相反呢？特别是最后几步的最后几种css实现方式，我在IE中的效果都是点击隐藏后盒子消失控制台打印一个hide，再点显示就什么都没有；然后我又在Chrome里试了试，发现效果一样，不管调用哪种动画都是只有点击隐藏的时候盒子隐藏，再点击就没有都不出现了，和IE不同的是打印结果会出现hidden但是只出现一次，再点击显示和隐藏也都会打印结果但是只有show和hide了，在控制台元素部分也能看出来盒子存在了但就是看不到。

同学你好，自己能够修改正确是很棒的哦！
还是transition过渡属性的问题，IE10版本以下的浏览器不支持这个属性
所以无法实现过渡效果，会直接显示隐藏。目前不考虑低版本浏览器，主流浏览器测试成功即可。
祝学习愉快！

我按照源码将以下部分修改后在Chrome中可以正确实现效果了，可是在IE中却只能实现生硬的显示和隐藏，没有那种渐变的动画，麻烦老师解答
在showHide.js中
function init($elem, hiddenCallback) {
if ($elem.is(':hidden')) { //hidden
$elem.data('status', 'hidden');
if (typeof hiddenCallback === 'function') hiddenCallback();
} else { //shown
$elem.data('status', 'shown');
}
}
css3._show = function ($elem, className) {
show($elem, function () {
$elem.off('transition.end').one('transition.end', function () {
$elem.data('status', 'shown').trigger('shown');
});
$elem.show();
setTimeout(function () {
$elem.removeClass(className);
}, 20);
});
};
css3._hide = function ($elem, className) {
hide($elem, function () {
$elem.off('transition.end').one('transition.end', function () {
$elem.hide();
$elem.data('status', 'hidden').trigger('hidden');
});
$elem.addClass(className);
});
};
另外我原本的文件命名都是showhide，后来改成了showHide，包括HTML中的引入名也改了
