HTML5前后比较滑块
HTML5前后比较滑块
提问于 2018-06-24 01:50:42
有很多“前后比较滑块”。我对改进它很感兴趣。
有没有可能在不点击的情况下滑动图片？我的意思是，除数(拖拽)将链接到鼠标。当用户只需鼠标悬停时(不像现在那样点击和拖动)，幻灯片就会改变。

是的，这在图片比较网站和像Buzzfeed/ClickHole这样的地方已经很常见了。
我已经修改了您的CodePen演示以使用mousemove事件，因此不需要单击/拖动：
var divisor = document.getElementById("divisor");
var comparisonWidth = document.getElementById("comparison").clientWidth;
function moveDivisor(e) {
divisor.style.width = (e.offsetX * 100 / comparisonWidth) + "%";
}div#comparison {
width: 60vw;
height: 60vw;
max-width: 600px;
max-height: 600px;
overflow: hidden;
}
div#comparison figure {
background-image: url(https://s3-us-west-2.amazonaws.com/s.cdpn.io/4273/photoshop-face-before.jpg);
background-size: cover;
position: relative;
font-size: 0;
width: 100%;
height: 100%;
margin: 0;
}
div#comparison figure>img {
position: relative;
width: 100%;
}
div#comparison figure div {
background-image: url(https://s3-us-west-2.amazonaws.com/s.cdpn.io/4273/photoshop-face-after.jpg);
background-size: cover;
position: absolute;
width: 50%;
box-shadow: 0 5px 10px -2px rgba(0, 0, 0, 0.3);
overflow: hidden;
bottom: 0;
height: 100%;
}<div id="comparison" onmousemove="moveDivisor(event)">
<figure>
<div id="divisor"></div>
</figure>
</div>
