原生JS实现H5页面侧滑删除的效果

目前很多H5框架都有类似QQ、微信消息侧滑删除的功能。如果工程并没有提供侧滑功能的时候该如何是好？。。。。得来全不费功夫，特此花费些时间编写的侧滑插件，希望能够帮助前端学习者的一些参考~~。本文根据实现此类效果展开说明以及演示。

• 基于移动端触摸事件touchstart、ontouchmove以及touchend事件。注意此三种事件的触发只能在手机上有效，电脑调试需切换手机调试模式。
• 使用CSS3 过度或者动画设置体验友好度

具体大家可以参考如下地址：

API参考地址:

如下代码基于本文章DEMO展开说明，此刻上码如下实例

1、初始化侧滑HTML结构

<div class="list">
	<div class="subListCon">
		<label style="justify-content: center;display: flex;line-height: 55px;">侧滑。。侧滑label>			
	div>
	<div class="subListTitle right">
		<a class="subRight collection" onclick="Delete()">收藏a>
		<a class="subRight update" onclick="Update()">修改a>
		<a class="subRight delete" onclick="Delete()">记忆a>
	div>
div>

2、基于如上HTML结构编写CSS 样式

.listContext{position: absolute;left: 0;right: 0;}
.listContext .list:first-child{border-top: 1px #ddd solid;}
.list{border: 1px #ddd solid;height: 55px;background-color: white;border-right: none;border-left: none;border-top: none;display: flex;user-select: none;}	
.subListCon{
	height: 100%;
	background-color: white;
	width: 100%;
				
	z-index: 999;
	transform: translate3d(0px,0px,0px);
	/*规定应用过渡的CSS属性*/
	transition-property:transform;
	/*规定应用过渡所花费的时间*/
	transition-duration: 0s;
	/*规定过渡效果从何开始，默认是0*/
	transition-delay: 0;
	/*规定过渡的时间曲线*/ 
	transition-timing-function: linear;
}
.subListTitle{position: absolute;line-height: 55px;}
.right{right: 0;}
.right > .subRight{display: block;float: left;padding: 0 12px;}
.delete{background-color: #ef473a;color: white;}
.update{background-color: #ffc900;color: white;}

3、JS处理控制。为了满足较好的体验以及复用性。在原生JS处理上还是比较复杂。

<script type="text/javascript">
	function touch(event) {
		//获取触发滑动事件的Dom元素
		var listDome = event.currentTarget.childNodes[0];
		//侧滑菜单
		var subCountWidth = event.currentTarget.childNodes[1].children;
		
			switch(event.type){
				case "touchstart" :
				
					//计算侧滑菜单宽度
					subWidth = 0;
					for(var i = 0;i<subCountWidth.length;i++) {
						subWidth = subWidth + subCountWidth[i].clientWidth;
					}
					
					listDome.style.transitionDuration = "0.3s";
					marginRight = window.getComputedStyle(listDome,"").transform;
					marginRight = Math.abs(Number(marginRight.substring(7,marginRight.length-1).split(",")[4]));
					//触摸点x轴距离
					$startX = event.touches[0].clientX;
					//触摸点至移动之后得到的x轴距离
					touchesX = 0;
					break;
				case "touchmove" :
					listDome.style.transitionDuration = "0s";
					$moveX = event.touches[0].clientX;
					touchesX = $startX - $moveX;
					console.log("移动X距离----"+touchesX);
					//滑块距离右边实际距离 >= 0时
					if(marginRight >= 0) {
						if(marginRight+touchesX < 0 ) {
							listDome.style.transform = 'translate3d(0px,0px, 0px)';
						}else if(marginRight+touchesX <= 500) {
							listDome.style.transform = 'translate3d(-'+(marginRight+touchesX)+'px,0px, 0px)';
						}else {
							listDome.style.transform = 'translate3d(-'+subWidth+'px,0px, 0px)';
						}
					}else if(marginRight < 0) {
							listDome.style.transform = 'translate3d(0px,0px, 0px)';
					}
					break;
				case "touchend" :
					listDome.style.transitionDuration = "0.3s";
					marginRight = window.getComputedStyle(listDome,"").transform;
					marginRight = Math.abs(Number(marginRight.substring(7,marginRight.length-1).split(",")[4]));
					if(marginRight <= 58 || touchesX <= -58) {
						listDome.style.transform = 'translate3d(0px,0px, 0px)';
					}else {
						listDome.style.transform = 'translate3d(-'+subWidth+'px,0px, 0px)';
					}
					break;
			}
		}
		
		
		document.addEventListener("DOMContentLoaded",function() {
			var listContext = document.getElementsByClassName("listContext");
			for(var i = 0;i<listContext.length;i++) {
				var listDOM = listContext[i].outerHTML;
				listDOM = listDOM.replace(/[\r\n\t]/g,'');
				listContext[i].outerHTML = listDOM;
			}
			
			
			/**
			 * 移动端侧滑菜单开始逻辑控制
			 */
			var list = document.getElementsByClassName("list");
			for(var i = 0;i<list.length;i++) {
				list[i].addEventListener("touchstart",touch,false);
				list[i].addEventListener("touchmove",touch,false);
				list[i].addEventListener("touchend",touch,false);
			}
			
			
			
			/**
			 * 触摸关闭侧滑菜单
			 */
			var subListCon = document.getElementsByClassName("subListCon");
			for(var i = 0;i<subListCon.length;i++) {
				
				subListCon[i].addEventListener("touchstart",function(event) {
					var thises = window.getComputedStyle(event.currentTarget,"").transform;
					thises = Math.abs(Number(thises.substring(7,thises.length-1).split(",")[4]));
					if(thises == 0) {
						var listContext = document.getElementsByClassName("listContext");
						for(var i = 0;i<listContext.length;i++) {
							var subListCon = document.getElementsByClassName("subListCon");
							for(var i = 0;i<subListCon.length;i++) {
								subListCon[i].style.transform = 'translate3d(0px,0px, 0px)';
							}
						}
					}
					event.currentTarget.style.backgroundColor = "#D9D9D9";
				},false);
				
				subListCon[i].addEventListener("touchmove",function(event) {
					event.currentTarget.style.backgroundColor = "white";
				},false);
				
				subListCon[i].addEventListener("touchend",function(event) {
					event.currentTarget.style.backgroundColor = "white";
				},false);
			}
		});
	script>

//更新：在iOS的微信,QQ,Safari等浏览器, 列表顶部下拉和底部上拉露出浏览器灰色背景的解决方案。会禁止window的touchmove 事件,从而阻止 iOS 的回弹效果.
window.addEventListener("touchmove",function(event) {
	event.preventDefault();
},{passive: false});
