我试图围绕一个圆圈旋转三个物体.到目前为止,我已经能够让一个物体围绕圆圈旋转.如果不弄乱代码,我无法获得多个.任何人都可以建议最好的方法来实现这一目标吗？这是代码和小提琴的一部分.谢谢！
这是Demo
.outCircle {
width: 200px;
height: 200px;
background-color: lightblue;
left: 270px;
position: absolute;
top: 50px;
-moz-border-radius: 100px;
-webkit-border-radius: 100px;
border-radius: 100px;
}
.rotate {
width: 100%;
height: 100%;
-webkit-animation: circle 10s infinite linear;
}
.counterrotate {
width: 50px;
height: 50px;
-webkit-animation: ccircle 10s infinite linear;
}
.inner {
width: 100px;
height: 100px;
background: red;
-moz-border-radius: 50px;
-webkit-border-radius: 50px;
border-radius: 100px;
position: absolute;
left: 0px;
top: 0px;
background-color: red;
display: block;
}
@-webkit-keyframes circle {
from {
-webkit-transform: rotateZ(0deg)
}
to {
-webkit-transform: rotateZ(360deg)
}
}
@-webkit-keyframes ccircle {
from {
-webkit-transform: rotateZ(360deg)
}
to {
-webkit-transform: rotateZ(0deg)
}
}
<div class="outCircle">
<div class="rotate">
<div class="counterrotate">
<div class="inner">hello
</div>
</div>
</div>
</div>
解决方法
Jquery解决方案适用于任何数量的外部项目.
Jquery从ThiefMaster♦无耻地偷走了他们在Q & A的回答
var radius = 100; // adjust to move out items in and out
var fields = $('.item'),container = $('#container'),width = container.width(),height = container.height();
var angle = 0,step = (2 * Math.PI) / fields.length;
fields.each(function() {
var x = Math.round(width / 2 + radius * Math.cos(angle) - $(this).width() / 2);
var y = Math.round(height / 2 + radius * Math.sin(angle) - $(this).height() / 2);
if (window.console) {
console.log($(this).text(),x,y);
}
$(this).css({
left: x + 'px',top: y + 'px'
});
angle += step;
});
body {
padding: 2em;
}
#container {
width: 200px;
height: 200px;
margin: 10px auto;
border: 1px solid #000;
position: relative;
border-radius: 50%;
animation: spin 10s linear infinite;
}
.item {
width: 30px;
height: 30px;
line-height: 30px;
text-align: center;
border-radius: 50%;
position: absolute;
background: #f00;
animation: spin 10s linear infinite reverse;
}
@keyframes spin {
100% {
transform: rotate(1turn);
}
}
