CSS 单击按钮时的转换 - CodePen 示例
CSS transition when clicking on button - CodePen example
我有一个按钮可以在礼物盒上方添加图片。它是 2 帧 - 礼物盒,以及按下按钮时上方的图像。
图片刚好“弹出”框上方。我希望图像(在本例中为卡车)从礼物盒平稳过渡,并从卡车现在的 box/the 相同位置向上一点。我该怎么做?
Codepen 有一个简单的例子:

function myFunction() {
document.getElementById("truck").innerHTML = `
<img src="https://i.pinimg.com/originals/e0/8b/14/e08b1415885d4d2ddd7fd3f75967da29.png"></img>`
console.log(this.show)
}
</script>
</head>
<body>
<div id ="truck"></div>
<img class="box" src="https://img.pngio.com/png-file-svg-box-icon-vector-png-transparent-cartoon-free-box-icon-png-920_852.png" on-click="handleClick"></img>
<button onclick="myFunction()">Click</button>
</body>
</html>
CSS:
.header {
display: flex;
align-items: center;
}
.circle {
height: 36px;
width: 36px;
border-radius: 50%;
visibility: visible;
background-color: var(green);
display: flex;
align-items: center;
justify-content: center;
}
.icon {
height: 26px;
width: 26px;
line-height: 0;
}
.header-text {
display: flex;
align-items: center;
margin-left: 14px;
height: 48px;
}
.container {
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
height: 100%;
}
img {
height: 240px;
width: 250px;
flex-grow: 0;
}
.box {
width: 350px;
height: 350px;
}
因为您没有编辑任何 CSS 属性。您只是使用 JavaScript.
创建一个新元素
您有两种选择:创建元素并使用 javascript 对其进行动画处理,或者更简单的方法是将元素置于页面中并对其高度进行动画处理,例如,使其出现。这是您的代码,其中将 class 切换到卡车 div 并根据其 classList:
出现或消失
<head>
<link rel="styles.css" />
</head>
<body>
<div id="truck"><img src="https://i.pinimg.com/originals/e0/8b/14/e08b1415885d4d2ddd7fd3f75967da29.png" class=""></img></div>
<img class="box" src="https://img.pngio.com/png-file-svg-box-icon-vector-png-transparent-cartoon-free-box-icon-png-920_852.png" on-click="handleClick"></img>
<button onclick="myFunction()">Click</button>
<script>
function myFunction() {
document.getElementById("truck").classList.toggle("visible");
}
</script>
</body>
</html>
#truck {
height: 0;
transition: all 1s ease;
}
#truck.visible {
height: 280px;
}
