uni-app自定義加載動畫組件

先寫好一個加載動畫組件，如：

<template>
	<view class="request-loading-view" v-show="loadingShow">
		<view class="loading-view"><view class="loading"></view></view>
	</view>
</template>

<script>
export default {
	data() {
		return {};
	},
	computed: {
		//計算屬性判斷vuex中的顯示狀態
		loadingShow() {
			return this.$store.state.requestLoading;
		}
	}
};
</script>

<style scoped>
.request-loading-view {
	position: fixed;
	top: 0;
	left: 0;
	width: 100%;
	height: 100%;
	z-index: 198903060;
	background-color: rgba(0, 0, 0, 0.001);
	display: flex;
	justify-content: center;
	align-items: center;
}
.loading-view {
	width: 160upx;
	height: 160upx;
	background-color: rgba(0, 0, 0, 0.6);
	border-radius: 20upx;
	display: flex;
	justify-content: center;
	align-items: center;
}

/* 動畫樣式 */
.loading {
	border: 10upx solid rgba(0, 0, 0, 0.01);
	border-radius: 50%;
	border-top: 10upx solid #fff;
	border-right: 10upx solid #fff;
	border-bottom: 10upx solid #fff;
	width: 60upx;
	height: 60upx;
	-webkit-animation: spin 1.4s linear infinite;
	animation: spin 1.4s linear infinite;
}

@-webkit-keyframes spin {
	0% {
		-webkit-transform: rotate(0deg);
	}

	100% {
		-webkit-transform: rotate(360deg);
	}
}

@keyframes spin {
	0% {
		transform: rotate(0deg);
	}

	100% {
		transform: rotate(360deg);
	}
}
</style>

main.js 中添加相應引用，使用Vuex來記錄顯示狀態，因此Vuex也須要引用

//Vuex
import store from './store'
Vue.prototype.$store = store

//請求加載組件
import requestLoading from './components/compt_requestLoading.vue';
//組件掛載到全局，方便每一個頁面使用
Vue.component('request-loading', requestLoading);

//掛載全局顯示/隱藏請求加載動畫
function showLoading(){
	store.commit('request_show_loading');
}
function hideLoading(){
	store.commit('request_hide_loading');
}
Vue.prototype.$showLoading = showLoading; //全局顯示動畫能夠 this.$showLoading();
Vue.prototype.$hideLoading = hideLoading; //全局隱藏動畫能夠 this.$hideLoading();

Vuex的store/index.js中這樣寫

//Vuex

import Vue from 'vue'
import Vuex from 'vuex'

Vue.use(Vuex)

const store = new Vuex.Store({
	state: {
		requestLoading: false //加載等待是否顯示
	},
	mutations: {
		//顯示請求加載動畫
		request_show_loading(state) {
			state.requestLoading = true;
		},
		//隱藏請求加載動畫
		request_hide_loading(state) {
			state.requestLoading = false;
		}
	}
})

export default store

而後每一個頁面添加標籤

<request-loading></request-loading>

便可

調用顯示/隱藏能夠直接

this.$showLoading()
this.$hideLoading()
