1.静态效果图

Chrom移动端浏览模式下可拖动按钮处于任意位置，并且点击可旋转按钮

2.代码

<template> <div id="app"> <div class="icon-add-50" :style="iconstyle" @click='click' @touchmove='touchmove' @touchstart='touchstart(this,$event)' @touchend='touchend'></div> </div></template><script>export default { name: 'App', data(){ return{ iconrotate:45,//旋转deg icontranslateX:100,//沿x轴位移px icontranslateY:100,//沿y轴位移px mouseX:0, mouseY:0, objX:0, objY:0, isDown:false } }, methods:{ click:function(){//图标点击事件 if (this.iconrotate==0) { this.iconrotate=315; }else { this.iconrotate=0; } }, touchstart:function(obj,e){//finger touch 触发 this.objX = this.icontranslateX; this.objY = this.icontranslateY; this.mouseX = e.touches[0].clientX; this.mouseY = e.touches[0].clientY; this.isDowm = true; }, touchmove:function(e){//finger move 触发 let x = e.touches[0].clientX; let y = e.touches[0].clientY; if (this.isDowm) { this.icontranslateX = parseInt(x) - parseInt(this.mouseX) + parseInt(this.objX); this.icontranslateY = parseInt(y) - parseInt(this.mouseY) + parseInt(this.objY); } }, touchend:function(e){//finger from touch to notouch if (this.isDowm) { let x = e.touches[0].clientX; let y = e.touches[0].clientY; this.icontranslateX = parseInt(x) - parseInt(this.mouseX)+ parseInt(this.objX); this.icontranslateY = parseInt(y) - parseInt(this.mouseY)+ parseInt(this.objY); this.isDowm=false; } } }, computed:{ iconstyle:function(){//图标动态样式 let arr = new Array(); arr.push('transform:');//注意：先移动后旋转，实现原地旋转；先旋转后移动，位置按照旋转后的新坐标系确定 arr.push('translateX('+this.icontranslateX+'px) '); arr.push('translateY('+this.icontranslateY+'px) '); arr.push('rotate('+this.iconrotate+'deg) '); return arr.join(""); } }}</script><style>#app { font-family: 'Avenir', Helvetica, Arial, sans-serif; -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; text-align: center; color: #2c3e50; margin-top: 60px;} .icon-add-50{ position: relative; box-sizing: border-box; width: 50px; height: 50px; border: 2px solid gray; border-radius: 50%; box-shadow:darkgrey 0px 0px 2px 2px; background-color: CornflowerBlue;}.icon-add-50:before{ content: ''; position: absolute; width: 30px; height: 2px; left: 50%; top: 50%; margin-left: -15px; margin-top: -1px; background-color: white;}.icon-add-50:after{ content: ''; position: absolute; width: 2px; height: 30px; left: 50%; top: 50%; margin-left: -1px; margin-top: -15px; background-color: white;}</style>
