不是很完美,无法做到第一个左滑其他的隐藏删除;
代码来源于 https://segmentfault.com/a/1190000011062124 自己做了写改动,添加父组件点击触发子组件
引入组件
<template> <div class="delete"> <div class="slider"> <div class="content" @touchstart='touchStart' @touchmove='touchMove' @touchend='touchEnd' :style="deleteSlider" > <!-- 插槽中放具体项目中需要内容 --> <slot></slot> </div> <div class="remove active" ref='remove' @click="handleClick"> 删除 </div> </div> </div> </template> <script type="text/ecmascript-6"> export default { props:{ propE: { type: Object, default: function () { } } }, data() { return { startX:0, //触摸位置 endX:0, //结束位置 moveX: 0, //滑动时的位置 disX: 0, //移动距离 deleteSlider: '',//滑动时的效果,使用v-bind:style="deleteSlider" } }, methods:{ handleClick (v) { this.$emit('msg-from-child', this.val) this.deleteSlider = "transform:translateX(0px)"; }, touchStart(ev){ console.log(ev) ev= ev || event //tounches类数组,等于1时表示此时有只有一只手指在触摸屏幕 if(ev.touches.length == 1){ // 记录开始位置 this.startX = ev.touches[0].clientX; } }, touchMove(ev){ ev = ev || event; //获取删除按钮的宽度,此宽度为滑块左滑的最大距离 let wd=this.$refs.remove.offsetWidth; if(ev.touches.length == 1) { // 滑动时距离浏览器左侧实时距离 this.moveX = ev.touches[0].clientX //起始位置减去 实时的滑动的距离,得到手指实时偏移距离 this.disX = this.startX - this.moveX; // 如果是向右滑动或者不滑动,不改变滑块的位置 if(this.disX < 0 || this.disX == 0) { this.deleteSlider = "transform:translateX(0px)"; // 大于0,表示左滑了,此时滑块开始滑动 }else if (this.disX > 0) { //具体滑动距离我取的是 手指偏移距离*5。 this.deleteSlider = "transform:translateX(-" + this.disX*5 + "px)"; // 最大也只能等于删除按钮宽度 if (this.disX*5 >=wd) { this.deleteSlider = "transform:translateX(-" +wd+ "px)"; } } } }, touchEnd(ev){ ev = ev || event; console.log(ev) let wd=this.$refs.remove.offsetWidth; if (ev.changedTouches.length == 1) { let endX = ev.changedTouches[0].clientX; this.disX = this.startX - endX; //如果距离小于删除按钮一半,强行回到起点 if ((this.disX*5) < (wd/2)) { this.deleteSlider = "transform:translateX(0px)"; }else{ //大于一半 滑动到最大值 this.deleteSlider = "transform:translateX(-"+wd+ "px)"; } } } } } </script> <style scoped lang="less" scoped> .slider{ width: 100%; height:100px; position: relative; user-select: none; .content{ position: absolute; left: 0; right: 0; top: 0; bottom: 0; background:green; z-index: 100; // 设置过渡动画 transition: 0.3s; } .remove{ position: absolute; width:100px; height:100px; background:red; right: 0; top: 0; color:#fff; text-align: center; font-size: 32px; line-height: 100px; } } </style>
将组件引入页面
<template> <div> <ul> <li v-for="item in data"> <leftSlider @msg-from-child="getMsgFromChild(item)"> <div> <p>哈哈这是一个标题:{{item.text}}-----{{item.id}}</p> </div> </leftSlider> </li> </ul> </div> </template> <script> import leftSlider from '../common/leftSlider.vue' export default{ components:{ leftSlider }, data (){ return { data:[{ text:'苹果', id:1 },{ text:'香蕉', id:2 },{ text:'橘子', id:3 },{ text:'菠萝', id:4 },{ text:'哈密瓜', id:5 }] } }, methods: { getMsgFromChild (v) { this.data.splice(v,1) } } } </script> <style> </style>
