Javascript / css 在 Internet Explorer 中不工作

Question

我正在通过浏览器测试站点（例如 Lambda 测试）在 Internet Explorer 上测试我的站点 - 但它根本无法运行。什么也没有发生，没有动静。这是怎么回事，我该如何解决？我已经在 IE 11 和 IE 9 上测试过了。

来自这篇文章：How to enable JavaScript in Windows

看起来有时您必须手动启用 javascript，我假设像 lambda test 这样的网站已经启用了此功能。我用的是Mac，所以我实际上不能用IE。

更新 - CSS:

 img
{
  display:none;
  height: 400px;
}


 img.invisible
{
  visibility: hidden;
}

img.show
{
  display:inline;
}

img.anim1
{
  animation-duration: 2000ms;
}

 img.anim2
{
  animation-duration: 2000ms;
}

img.anim3
{
  animation-duration: 2000ms;
}


.fadeIn
{
  animation-name: fadeIn;
}

@keyframes fadeIn 
{
 0% {opacity: 0;}
 100% {opacity: 1;}
}


@-ms-keyframes fadeIn 
{
 0% {opacity: 0;}
 100% {opacity: 1;}
}

.fadeOut
{
  animation-name: fadeOut;
}

@-ms-keyframes fadeOut 
{
 0% {opacity: 1;}
 100% {opacity: 0; display:none;}
}

Answer 1

您尝试使用 IE 不支持的 lambda 函数和 map ES6 函数。如果你使用 jQuery 那么你可以使用 jQuery 等价于 ES6 映射函数：

var mappedArray = $.map(realArray, function(val, i ) {
  // Do something
});

您还应该使用 var 而不是 let 和 const 关键字，它们也不被 IE 支持。

替换你的数组函数

IMAGE_URLS.map((url, index) => {}

与：

jQuery.map(IMAGE_URLS, function (url, index)
{
  //mapping code here
}

Answer 2

关于es6语法问题，我想你已经根据评论和更早的答案进行了更正。您应该在代码中解决另一个问题：IE 11 doesn't support classList 中 add() 和 remove() 的多个参数。所以你不能使用像

这样的代码

setTimeout(function() { IMAGES[imgIndexBase].classList.add('fadeIn','show'); }, 0);

您需要将其更改为

setTimeout(function () { IMAGES[imgIndexBase].classList.add('fadeIn'); }, 0);
setTimeout(function () { IMAGES[imgIndexBase].classList.add('show'); }, 0);

另外 classList.add() 和 classList.remove() 在您的代码中有多个参数也是一样的。

所以您的代码片段的编辑部分如下所示：

//edit arrow function

var IMAGES = IMAGE_URLS.map(function (url, index) {
    var img = document.createElement('img');
    img.setAttribute('src', url);
    img.classList.add('anim' + (index % 3 + 1));
    img.classList.add('fadeOut');
    document.getElementById('images').appendChild(img);
    return img;
});

//edit classList in function Type()

let imgIndexBase = _PART * 3;
IMAGES[imgIndexBase].classList.remove('fadeOut');
IMAGES[imgIndexBase + 1].classList.remove('fadeOut');
IMAGES[imgIndexBase + 2].classList.remove('fadeOut');
setTimeout(function () { IMAGES[imgIndexBase].classList.add('fadeIn'); }, 0);
setTimeout(function () { IMAGES[imgIndexBase].classList.add('show'); }, 0);
setTimeout(function () { IMAGES[imgIndexBase].classList.add('fadeOut'); }, 2000);
setTimeout(function () { IMAGES[imgIndexBase].classList.remove('fadeOut'); }, 3000);
setTimeout(function () { IMAGES[imgIndexBase].classList.remove('show'); }, 3000);
setTimeout(function () { IMAGES[imgIndexBase + 1].classList.add('fadeIn'); }, 3000);
setTimeout(function () { IMAGES[imgIndexBase + 1].classList.add('show'); }, 3000);
setTimeout(function () { IMAGES[imgIndexBase + 1].classList.add('fadeOut'); }, 5000);
setTimeout(function () { IMAGES[imgIndexBase + 1].classList.remove('fadeOut'); }, 7000);
setTimeout(function () { IMAGES[imgIndexBase + 1].classList.remove('show'); }, 7000);
setTimeout(function () { IMAGES[imgIndexBase + 2].classList.add('fadeIn'); }, 7000);
setTimeout(function () { IMAGES[imgIndexBase + 2].classList.add('show'); }, 7000);
setTimeout(function () { IMAGES[imgIndexBase + 2].classList.add('fadeOut'); }, 9000);
setTimeout(function () { IMAGES[imgIndexBase + 2].classList.remove('fadeOut'); }, 10000);
setTimeout(function () { IMAGES[imgIndexBase + 2].classList.remove('show'); }, 10000);
