我正在尝试将'旋转回顶部'悬停时按钮360度,在鼠标左键不旋转。我尝试过多种jQuery代码,但我仍然无法让它运行起来。这是我到目前为止所获得的真实例子(CSS也在图像之间悬停)。
我已尝试将jQuery更改为mouseenter
,mouseover
,hover
以及在;
号码后包含和省略rotate
为no无济于事。这是一个简单的jQuery语法错误吗?我正在制作?
HTML:
<div class="scrollup">
<img src="https://static1.squarespace.com/static/56b92ff8e707ebc576b99166/t/57e099d215d5dbdafb6373aa/1474337234028/top-circleonly.png" class="scrollImg1 scrollup-circle"/>

</div>
CSS:
.scrollup {
width: 45px;
height: 45px;
display: block;
margin-left: auto;
position: relative;
cursor: pointer;
}
.scrollup img {
position: absolute;
}
.scrollImg2 {
opacity: 0;
}
.scrollup:hover > .scrollImg1 {
opacity: 0;
}
.scrollup:hover > .scrollImg2 {
opacity: 1;
}
JQuery的:
$(".scrollup").mouseover(function() {
$(".scrollup-circle").rotate(360);
});

你可以使用下面的jQuery
<!DOCTYPE html>
<html>
<head>
<title></title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
</head>
<style type="text/css">
div.main{
width: 100px;
height: 100px;
}
div.main img{
width: 100%;
height: 100%;
}
.change{
-ms-transform: rotate(360deg); /* IE 9 */
-webkit-transform: rotate(360deg); /* Chrome, Safari, Opera */
transform: rotate(360deg);
transition-duration: 5s;
}
</style>
<body>
<div class="main">
<img src="https://image.freepik.com/free-icon/apple-logo_318-40184.jpg">
</div>
<p id="dis"></p>
<script type="text/javascript">
$("div.main").mouseenter(function(){
$(this).addClass("change").delay(5000).queue(function(){
$(this).removeClass("change").dequeue();
});
});
</script>
</body>
</html>

注意:(AFTER)---&gt;我在你上次的评论中没有得到你真正的要求。但请试试这个问题:)。希望它会对你有帮助。

您可以使用带旋转动画的css变换
.scrollup {
width: 45px;
height: 45px;
display: block;
margin-left: auto;
position: relative;
cursor: pointer;
}
.scrollup img {
position: absolute;
-webkit-transition: -webkit-transform .8s ease-in-out;
transition: transform .8s ease-in-out;
}
.scrollImg2 {
opacity: 0;
}
.scrollup:hover{
}
.scrollup:hover > img {
opacity: 0;
-webkit-transform: rotate(360deg);
transform: rotate(360deg);
}
.scrollup:hover > .scrollImg2 {
opacity: 1;
}

您可以使用Sys.queue
if(!Sys.queue.isEmpty())
{
algo = new SortingAlgo(Sys.queue, clock);
Sys.queue = algo.sorted_queue;
// For-loop on next line changed to old-style for-loop:
for (Iterator<Request> iterator = Sys.queue.iterator(); iterator.hasNext();)
{
Request r = iterator.next();
{
for(Porter p : p_i.porList)
{
if(p.p_state.equals("Available"))
{
iterator.remove(); // The safe way to remove while iterating
}
}
}
}
}
,css
,animation
事件。在.hover()
事件处理程序中将animationend
元素设置为animation-name
的名称,将@keyframes
元素设置为.hover()
事件中的空字符串
animation-name
animationend
$(".scrollup")
.hover(function() {
$(this).css({"animationName":"rotate",
"mozkitAnimationName":"rotate",
"webkitAnimationName":"rotate"});
})
.on("animationend.rotate", function() {
$(this).css({"animationName":"",
"mozkitAnimationName":"",
"webkitAnimationName":""});
});
