Vue+element table+原生js +touch触摸事件实现移动端横向拖动
今天做移动端项目时，想加个表格展示数据，但是调试的时候发现，表格数据很多时，想要触屏左右滑动内容，但是滑动不了，又不想引用插件实现，只好自己写个拖拽事件了
<el-cardshadow="never"v-show="tableCardTitle"class="table-wrapper"><div slot="header" class="clearfix"><span>{{tableCardTitle }}</span></div><el-table :data="tableData" stripe ><el-table-column:prop="item.key":label="item.name"v-for="(item, index) in tableLabel":key="index"></el-table-column></el-table></el-card>
updated() {this.addrag();}methods: {addDrag() {const tableWrapperEls = document.querySelector(".el-card__body");console.log(tableWrapperEls);const tableEls = document.querySelector(".el-table--scrollable-x .el-table__body-wrapper");console.log(tableEls);let isDragging = false; // 是否正在拖动let startX = 0; // 拖动开始的X坐标let scrollLeft = 0; // 横向滚动的距离tableWrapperEls.addEventListener("touchstart", (e) => {isDragging = true;startX = e.touches[0].pageX - tableWrapperEls.offsetLeft;scrollLeft = tableEls.scrollLeft;});tableWrapperEls.addEventListener("touchmove", (e) => {if (!isDragging) return;e.preventDefault();//阻止默认行为const x = e.touches[0].pageX - tableWrapperEls.offsetLeft;const walk = (x - startX) * 2; // 控制拖动速度tableEls.scrollLeft = scrollLeft - walk;});tableWrapperEls.addEventListener("touchend", () => {isDragging = false;});},}
<style scoped>.table-wrapper {overflow-x: auto;-webkit-overflow-scrolling: touch;}</style>
