如何使用jquery在悬停时旋转图像？ [英] How do I rotate an image on hover using jquery?
问题描述
我试图在悬停时将回到顶部按钮旋转360度而不在鼠标上旋转。我已经尝试了多种jQuery代码，我发现但我仍然无法让它工作。这是我到目前为止的真实例子（CSS也在图像之间悬停）。
I am trying to rotate a 'back to top' button 360 degrees on hover WITHOUT un-rotating on mouseleave. I have tried multiple variations of jQuery code that I've found but I still can't seem to get it working. Here's the real example of where I've gotten so far (CSS hover between images as well).
我尝试将jQuery更改为 mouseenter ， mouseover ，悬停以及在 rotate ; $ c>数字，无济于事。我正在制作一个简单的jQuery语法错误吗？
I have tried changing the jQuery to mouseenter, mouseover, hover as well as including and omitting the ; after the rotate number, to no avail. Is it a simple jQuery syntax mistake that I'm making?
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：
$(".scrollup").mouseover(function() {
$(".scrollup-circle").rotate(360);
});
推荐答案
你可以用来做jQuery 如下所示
<!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:(之后）--->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。
