uni-app中实现元素拖动
1、代码示例
<template> <movable-area class="music-layout"> <movable-view class="img-layout" :x="x" :y="y" direction="all"> <img :src="musicDetail.bgUrl" :class="[ isPlay ? 'rotate-img' : '']" @click="onImgClick"> <view class="small-circle"></view> </movable-view> </movable-area> </template> <script> export default { name: "music-icon", props: { musicDetail: { type: Object, default: {} } }, data() { return { innerAudioContext: {}, x: 300, y: 500, isPlay: true, } }, watch: { musicDetail: { handler(newVal, oldVal) { if (newVal.music) { this.handlePlay(); } }, immediate: true } }, methods:{ handlePlay() { this.innerAudioContext = uni.createInnerAudioContext(); this.innerAudioContext.src = this.musicDetail.music; this.innerAudioContext.startTime = 0; this.innerAudioContext.play(); this.innerAudioContext.loop = true; // 循环播放 }, onImgClick() { this.isPlay = !this.isPlay; if (this.isPlay) { this.innerAudioContext.play(); } else { this.innerAudioContext.pause(); } } } } </script> <style scoped lang="scss"> .music-layout { height: 100vh; width: 750rpx; top: 0; position: fixed; pointer-events: none; //鼠标事件可以渗透 } .img-layout { position: relative; width: 100rpx; height: 100rpx; border-radius: 50%; overflow: hidden; pointer-events: auto; //恢复鼠标事件 img { width: 100%; height: 100%; border-radius: 50%; } .small-circle{ position: absolute; left: 50%; top: 50%; transform: translate(-50%, -50%); width: 20rpx; height: 20rpx; background-color: white; border-radius: 50%; } } .rotate-img { width: 80rpx; height: 80rpx; border-radius: 50%; transform-origin: center center; animation: rotate 5s infinite linear; } @keyframes rotate { from { transform: rotate(0deg); } to { transform: rotate(360deg); } } </style>
利用的是uni-app中的movable-area和movable-view两个组件配合实现
