vue实现简易的全局加载动画效果

效果展示

思路

封装一个组件，放Img，伪类样式，固定在屏幕fixed

然后App应用这个组件，Z index拉最大，防止用户在加载动画时乱点，

v-show绑定loading，该数据可以放vuex还是任一的公共状态管理变量区域

代码

<template><!--组件的结构--><div class="loading-bg"><div class="loading-img"></div><div class="loading-image-dot"></div></div>
</template>
<script>
//组件交互相关的代码(数据、方法等等)
export default {name: 'pageLoading',data() {return {}},methods: {},
}
</script><style>
.loading-bg {width: 100%;height: 100%;background: rgba(0, 0, 0, 0.2);position: fixed;display: flex;justify-content: center;align-items: center;z-index: 100000;
}.loading-img {width: 100px;height: 100px;background: url('https://cdn.zww0891.fun/%E5%BE%AE%E4%BF%A1%E5%9B%BE%E7%89%87_20240701112347.jpg') center center;background-size: cover;border-radius: 50%;border: 4px solid #f0f0f2;animation: blink infinite ease 0.5s;
}.loading-image-dot:before {content: '';position: absolute;background: #6bdf8f;border: 4px solid #f0f0f2;border-radius: 50%;width: 30px;height: 30px;top: 50%;left: 50%;transform: translateX(20px) translateY(20px);
}@keyframes blink {0% {opacity: 0.4;}50% {opacity: 1;}100%{opacity: 0.4;}
}
</style>
