【vue】圆环呼吸灯闪烁效果(模拟扭蛋机出口处灯光）

效果图先发：

页面部分：

<div ref="round" class="round"><div class="light" ref="light"/><div class="box"></div></div>

js部分(控制圆环生成）;

setRound() {let lightFragment = document.createDocumentFragment();for (let i = 0; i < 10; i++) {let lightItem = document.createElement('span');let deg = (360 / 10) * ilightItem.style.transform = `rotate(${deg}deg)`;lightItem.classList.add('ball_span')lightFragment.appendChild(lightItem);}this.$refs.light.appendChild(lightFragment);},

样式部分：
（js动态部分的样式需要放在不加scope的标签中）
