如何使用Hammer.js刷卡?
How to use Hammer.js for swiping?
所以我 hammer.js 滑动即可在我的 div 上工作。滑动区域看起来像这样
所以基本上,我希望橙色区域能够滑动 left/right,当它到达末端(两侧)时,它会停止滑动。
脚本等:
var containerDiv = document.getElementById('list-container');
var listDiv = document.getElementById('train-line-list');
// Create a manager to manager the element
var manager = new Hammer.Manager(listDiv);
// Create a recognizer
var Swipe = new Hammer.Swipe();
// Add the recognizer to the manager
manager.add(Swipe);
// Declare global variables to swiped correct distance
var deltaX = 0;
var deltaY = 0;
// Subscribe to a desired event
manager.on('swipe', function(e) {
deltaX = deltaX + e.deltaX;
var direction = e.offsetDirection;
var translate3d = 'translate3d(' + deltaX + 'px, 0, 0)';
if (direction === 4 || direction === 2) {
e.target.innerText = deltaX;
e.target.style.transform = translate3d;
}
});
<div id="list-container">
<div id="train-line-list">
<img id="" src="">
<img id="" src="">
</div>
#list-container{
z-index: 10;
position:fixed;
top:60%;
left:0;
width:100%;
height:40%;
}
#train-line-list{
width: 95%;
height: 95%;
top: 2%;
margin: 0 auto;
position: relative;
}
就像我说的,滑动类型有效,但图像消失了。为什么会发生这种情况,我该如何解决?此外,滑动在某种程度上不是很 "reactive",比如它很慢。不自然。有其他选择吗?或更好的实施方式?另外,刚刚意识到,图像也可以滑动??我如何 "lock" 图片。我只想刷一下图片的容器。
这是一个工作示例
<html>
<head>
<style>
#box {
background-color: red;
height: 100px;
width: 100px;
margin-right: 10px;
}
#collection {
display: flex;
flex-direction: horizontal;
}
#container {
display: flex;
background-color: aqua;
padding: 50px 0px 50px 0px;
overflow: scroll;
}
</style>
<script src="https://cdnjs.cloudflare.com/ajax/libs/hammer.js/2.0.8/hammer.js"></script>

var container = document.getElementById("container");
var content = document.getElementById("collection");
var hammer = new Hammer(container);
var initialX = 0;
var deltaX = 0;
var offset = initialX + deltaX;
hammer.on("panleft panright", function(ev) {
deltaX = ev.deltaX;
offset = initialX + deltaX;
container.scroll(-offset, 0);
});
Hammer.on(container, "mouseup", function(e) {
initialX = offset;
});
</script>
