渐入在IE上不起作用 [英] Fade In doesn't work on IE

问题描述

我正在使用此代码在页面加载时淡入图像.在我测试过的所有浏览器中都能正常工作，但Windows上的IE除外.

I am using this code to fade-in images when the page loads. Works fine in all browsers I have tested except from IE on Windows.

@-webkit-keyframes fadeIn { from { opacity:0; } to { opacity:1; } }
@-moz-keyframes fadeIn { from { opacity:0; } to { opacity:1; } }
@keyframes fadeIn { from { opacity:0; } to { opacity:1; } }

.fade-in {opacity:0;-webkit-animation:fadeIn ease-in 1;-moz-animation:fadeIn ease-in 1;animation:fadeIn ease-in 1;-webkit-animation-fill-mode:forwards;-moz-animation-fill-mode:forwards;animation-fill-mode:forwards;-webkit-animation-duration:1.5s;-moz-animation-duration:1.5s;animation-duration:1.5s;}

.fade-in.one {-webkit-animation-delay: 0.3s;-moz-animation-delay: 0.3s;animation-delay: 0.3s;}
.fade-in.two {-webkit-animation-delay: 0.6s;-moz-animation-delay:0.6s;animation-delay: 0.6s;}
.fade-in.three {-webkit-animation-delay: 0.9s;-moz-animation-delay: 0.9s;animation-delay: 0.9s;}

有什么想法吗?

推荐答案

您正在使用

You are using this method and it has a warning for IE:

警告！此CSS3代码仅适用于Firefox，Chrome，Safari和 也许是IE的较新版本(版本9之后)

Warning! This CSS3 code will only work on Firefox, Chrome, Safari and maybe newer versions of IE (after version 9)

由于IE9不支持css3动画，但支持不透明度:0; 属性，您将不得不让ie9加载一个单独的ie9 css， 将所有淡入淡出类都设置为不透明:1

Since IE9 doesn’t support css3 animations but does support opacity: 0; property you will have to have ie9 load a separate ie9 css where you have all your fade classes set to opacity: 1

如果您正在寻找替代品:

If you are looking for alternative:

如果您正在寻找自动调用的过渡，则应使用 CSS3动画，它们也不被支持，但这恰恰是它们制作的目的.

If you are looking for a self-invoking transition then you should use CSS3 Animations, they aren't supported as well but this is exactly the kind of thing they were made for.

#test p {
    margin-top: 25px;
    font-size: 21px;
    text-align: center;

    -webkit-animation: fadein 2s; /* Safari, Chrome and Opera > 12.1 */
       -moz-animation: fadein 2s; /* Firefox < 16 */
        -ms-animation: fadein 2s; /* Internet Explorer */
         -o-animation: fadein 2s; /* Opera < 12.1 */
            animation: fadein 2s;
}

@keyframes fadein {
    from { opacity: 0; }
    to   { opacity: 1; }
}

/* Firefox < 16 */
@-moz-keyframes fadein {
    from { opacity: 0; }
    to   { opacity: 1; }
}

/* Safari, Chrome and Opera > 12.1 */
@-webkit-keyframes fadein {
    from { opacity: 0; }
    to   { opacity: 1; }
}

/* Internet Explorer */
@-ms-keyframes fadein {
    from { opacity: 0; }
    to   { opacity: 1; }
}

/* Opera < 12.1 */
@-o-keyframes fadein {
    from { opacity: 0; }
    to   { opacity: 1; }
}

或者，您可以使用jQuery(或普通JS，请参见第三个代码块)在加载时更改类:

Alternatively, you can use jQuery (or plain JS, see third code block) to change the class on load:

$("#test p").addClass("load");​

CSS

#test p {
    opacity: 0;
    font-size: 21px;
    margin-top: 25px;
    text-align: center;

    -webkit-transition: opacity 2s ease-in;
       -moz-transition: opacity 2s ease-in;
        -ms-transition: opacity 2s ease-in;
         -o-transition: opacity 2s ease-in;
            transition: opacity 2s ease-in;
}

#test p.load {
    opacity: 1;
}

普通JS(不在演示中)

document.getElementById("test").children[0].className += " load";

或者，您可以使用 .Mail 使用的方法:

Or, you can use the method that .Mail uses:

$("#test p").delay(1000).animate({ opacity: 1 }, 700);​

CSS

#test p {
    opacity: 0;
    font-size: 21px;
    margin-top: 25px;
    text-align: center;
}

jQuery 1.x :所有现代浏览器，IE 6+: http: //jquery.com/browser-support/

jQuery 1.x: All modern browsers, IE 6+: http://jquery.com/browser-support/
jQuery 2.x: All modern browsers, IE 9+: http://jquery.com/browser-support/

此方法是最兼容的方法，因为目标浏览器不需要支持CSS3过渡或动画.

This method is the most cross-compatible as the target browser does not need to support CSS3 transitions or animations.
