`src / lib / loading.js页面`

import vue from 'vue'
    import loadingComponent from '../components/loading'
    
    const ToastConstructor = vue.extend(loadingComponent)
    
    function showToast (text, duration = 2000) { 
        const toastDom = new ToastConstructor({ 
            el: document.createElement('div'),
            data () { 
                return { 
                    text: text,
                    showWrap: true,    // 是否显示组件
                    showContent: true  // 作用:在隐藏组件之前,显示隐藏动画
                }
            }
        })
        document.body.appendChild(toastDom.$el)
    
        setTimeout(() => {  toastDom.showContent = false }, duration - 1250)
        setTimeout(() => {  toastDom.showWrap = false }, duration)
    }
    
    function registryToast () { 
        vue.prototype.$toast = showToast
    }
    
    export default registryToast

在`main.js`中引入：

import loading from './lib/loading' // 引入loading
    Vue.use(loading) // 全局使用loading

## 使用方法： ##

this.$toast('查询支付结果', 3000)
