带动画的CSS灰度 [英] CSS grayscale with animation
问题描述
我有一些css用于将我的图像更改为灰度(使用一些svg for firefox)
img.grayscale {
filter:灰度(100%);
-webkit-filter:灰度(100%);
-moz-filter:灰度(100%);
-ms-filter:灰度(100%);
-o-filter:灰度(100%);
filter:url(desaturate.svg#greyscale);
过滤器:灰色;
-webkit-filter:grayscale(1);
}
但现在我希望悬停动画,将灰度值更改为0 。
我有这个代码,但它没有做任何事情(当然在Chrome上),我不知道为什么它根本没有动画。
< script type =text / javascript>
$(。grayscale)。悬停(
function(){
$(this).animate({
'-webkit-filter':'grayscale('0 '%)'
},300);
}
);
< / script>
我认为可以将%从100%设为0%,不是吗? / p>
编辑:我正在尝试为所有浏览器做,不仅是chrome,而且我在chrome上进行测试,这就是为什么我没有改变所有属性。我想当我找到chrome的答案时我会为其他浏览器做同样的事情:)
为什么根本使用animate()?您已经只是为webkit制作动画,那么为什么不使用过渡属性和类来触发动画呢?像这样:
img {
-webkit-transition:all 300ms;
}
img.grayscale {
-webkit-filter:grayscale(1);
}
然后只需通过调用
删除课程
$('img.grayscale')。removeClass('grayscale');
注意:我不知道仅仅为灰度设置动画的具体属性是什么,但是如果你没有对元素进行任何其他转换,那么转换all就可以了。
i have some css for changing my image into grayscale (with some svg for firefox)
img.grayscale{
filter: grayscale(100%);
-webkit-filter: grayscale(100%);
-moz-filter: grayscale(100%);
-ms-filter: grayscale(100%);
-o-filter: grayscale(100%);
filter: url(desaturate.svg#greyscale);
filter: gray;
-webkit-filter: grayscale(1);
}
but now i want animation on hover for changing the value of the grayscale to 0.
I have this code but it doesn't do anything (on chrome of course), i have no idea why it doesn't animate at all.
<script type="text/javascript">
$(".grayscale").hover(
function () {
$(this).animate({
'-webkit-filter': 'grayscale('0'%)'
}, 300);
}
);
</script>
I think it's possible to animate the % from 100% to 0%, isn't it?
Edit : i'm trying to do for all browsers, not only chrome but i do my tests on chrome that's why i'm not changing all the properties. I think when i'll found the answer for chrome i'll can do the same for the other browers :)
Why use animate() at all? You're already only animating for webkit, so why not use the transition property and classes to trigger the animation? Like this:
img {
-webkit-transition: all 300ms;
}
img.grayscale {
-webkit-filter: grayscale(1);
}
And then just remove the class by calling
$('img.grayscale').removeClass('grayscale');
Note: I don't know what the specific property is to just animate just the grayscale, but if you're not doing any other transitions on the element, transitioning "all" works just fine.
