我试图将图像从原点旋转(转换)为圆形,或者更确切地说是顺时针旋转。我已成功设置了相对于我的模态的图像的绝对中心。我完全控制了几分钟和几小时。问题是,我需要日期指示器(在这种情况下我只有夜间时间)来同时跟踪小时指示器(或#34;手")。我只能设法手动完成:manual adjustment。但随着时间的推移,它会回到原来的位置,或类似的东西,我还没有看到每一步:out of circle。这是我的代码:
CSS:
#clock {
display: -webkit-box;
margin-left: auto;
margin-right: auto;
/*margin: 0 auto;*/
padding: 100px;
position: relative;
}
.minutes {
position: absolute;
/*top: -90px;
left: -27px;*/
left: 0;
right: 0;
top: 0;
bottom: 0;
margin: auto;
z-index: 1;
width: 208.5px;
height: 208.5px;
transition: transform 0.3s cubic-bezier(.4,2.08,.55,.44);
}
.hours {
left: 0;
right: 0;
top: 0;
bottom: 0;
margin: auto;
z-index: 2;
height: 155.5px;
position: absolute;
transition: transform 0.3s cubic-bezier(.4,2.08,.55,.44);
}
.night {
left: 0;
right: 0;
top: 0;
bottom: 0;
margin: auto;
position: absolute;
z-index: 3;
height: 50px;
transform-origin: 120px 0px;
-webkit-transform-origin: 120px 0px;
-webkit-transition: transform 0.3s cubic-bezier(.4,2.08,.55,.44);
transition: transform 0.3s cubic-bezier(.4,2.08,.55,.44);
}
Javascript:
let rings = [], elements = [];
rings = [{
ring: 'minutes',
angle: 0
},
{
ring: 'hours',
angle: 0
},
{
ring: 'night',
angle: 0
}
];
for (let index = 0; index < rings.length; index++) {
elements[index] = document.querySelector('.' + rings[index].ring);
}
setInterval(function () {
let now = new Date();
minutes = now.getMinutes();
hours = now.getHours();
for (var id = 0; id < rings.length; id++) {
if (rings[id].ring === 'minutes') {
rings[id].angle = minutes * 6;
} else if (rings[id].ring === 'hours') {
rings[id].angle = (hours * 30) + (minutes / 2);
} else if (rings[id].ring === 'night') {
rings[id].angle = (hours * 30) + (minutes / 2);
} else {
console.log('Err: ');
}
elements[id].style.webkitTransform = 'rotateZ(' + rings[id].angle + 'deg)';
elements[id].style.transform = 'rotateZ(' + rings[id].angle + 'deg);';
}
}, 1000);
HTML:
<div id="clock">
<img src="res/termina_clock/outside.png" alt="" class="minutes">
<img src="res/termina_clock/inside.png" alt="" class="hours">
<img src="res/termina_clock/night.png" alt="" class="night">
</div>
答案 0 :(得分:3)
您需要做的是在day/night
内嵌套hours
指示符。然后你可以精确定位它。
<div id="clock">
<img src="http://i.imgur.com/4k04SRS.png" alt="" class="minutes">
<div class="hours">
<img src="http://i.imgur.com/9cQMi2m.png" alt="" class="night">
</div>
</div>
我还必须摆脱您的自定义transform-origin
,因为它不再需要并且正在弄乱定位。
.night {
/*transform-origin: 120px 0px;*/
/*-webkit-transform-origin: 120px 0px;*/
}
