uni判斷上下滑動還是左右滑動

最近在做uni-app，要配合插件市場的一款增強版的抽屜做一個在首頁向右滑動抽屜打開想左滑動抽屜關閉的效果，上代碼

<view class="wrapper" @touchstart="fingerstart" @touchend="fingerend">
//...中間是內容
</view>

export default { data() { return { startData: { clientX: '', clientY: '' }, } }, methods: { fingerstart(e) { this.startData.clientX = e.changedTouches[0].clientX; this.startData.clientY = e.changedTouches[0].clientY; }, fingerend(e) { const subX = e.changedTouches[0].clientX - this.startData.clientX; const subY = e.changedTouches[0].clientY - this.startData.clientY; if (subY > 50 || subY < -50) { if (subY > 50) { console.log('下滑') } else if (subY < -50) { console.log('上滑') } } else { if (subX > 100) { console.log('右滑') } else if (subX < -100) { console.log('左滑') } else { console.log('無效') } } } } }
