<body>
<button id = "sunButton" onclick="sunPausePlayToggle()">PLAY/PAUSE</button
sunPausePlayToggle((是JS中的一个函数，它将控制动画。
<div id = "sunSky"
这是一个我用作背景天空的div
<div id = "sun"></div
上方的div是从右侧升起的太阳，在左侧中黎明
</div>
</body>
</html>
CSS code:
我正在使用关键帧动画来设置太阳和天空的动画。
@keyframes risesky {
0% {
top: 100%;
left : 100%;
background-color: red;
}
50% {
left:50%;
top: 10%;
background-color: yellow;
}
100% {
background-color: orangered;
top: 100%;
left: 0%;
}
}
@keyframes sky {
0% , 100% {
background-color: #1c1341;
}
10% {
background-color: darkorange;
}
50% {
background-color: skyblue;
}
80% {
background-color: crimson;
}
}
#sunButton{
animation-play-state: running;
}
#sun {
position: relative;
border-radius: 50%;
width: 80px;
height: 80px;
animation: risesky 11s infinite;
}
#sunSky {
height: 500px;
overflow: hidden;
animation: sky 11s infinite both;
}
Javascript code:
这是我遇到的问题，我只能暂停JS中的动画，但无法播放。
function sunPausePlayToggle(){
document.getElementById("sunSky").style.animationPlayState = "paused";
document.getElementById("sun").style.animationPlayState = "running";
}
Turn#sunButton=动画播放状态："暂停"；；在css中
这是js
function sunPausePlayToggle(){
let sunsky = document.getElementById("sunSky")
let sun = document.getElementById("sun")
const sky_sty = sunsky.style.animationPlayState === 'running';
const sun_sty = sun.style.animationPlayState === 'running';
sunsky.style.animationPlayState = sky_sty ? 'paused' : 'running';
sun.style.animationPlayState = sun_sty ? 'paused' : 'running';
}
