Vue动态Loading加载中纯Css实现

如图所示：

等待数据返回等等...

开箱即用比UI好用

<template>
    <div>
        <button @click="showLoading">显示加载中消息</button>
        <div v-if="loading" class="loading">
            <div class="loading-message">
                <div class="loading-spinner"></div>
                <div class="loading-text">加载中...</div>
            </div>
        </div>
    </div>
</template>

<script>
import { ref } from 'vue'

export default {
    setup() {
        const loading = ref(false)

        function showLoading() {
            loading.value = true
        }

        function hideLoading() {
            loading.value = false
        }

        return {
            loading,
            showLoading,
            hideLoading
        }
    }
}
</script>
