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
然后增加vue自带的transition过渡动画,类样式控制过渡时间

组件代码
html
<template>
<!--组件的结构-->
<transition name="fade" class="fade-enter-active fade-leave-active">
<div class="loading-bg">
<div class="loading-img"></div>
<div class="loading-image-dot"></div>
</div>
</transition>
</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%;

@keyframes loadingAction {

opacity: 1;
/*-ms-filter: none;*/
/*filter: none;*/
}
100% {
opacity: 0.4;
}
}
/*@keyframes blink {*/
/* 0% {*/

</style>
应用代码
这里我放在了app起到全局覆盖的作用,同时绑定vuex的值
发送请求时commit修改loading值,可以设置加载时长,这里我设置了500ms
