toast的index.js
// 导入.vue组件,导出一个函数,方便我们直接以函数的方式来调用组件

// 1. 导入组件
// ----- 显示 ------
// 2. 根据组件创建虚拟节点. const vnode = createVNode(XtxMessage, { type, text })
// 3. 准备一个DOM容器
// 4. 把虚拟节点渲染DOM容器中. render(vnode, div)
// -----隐藏DOM-----
// 5. 开启定时器,移出DOM容器内容 render(null, div)
import { createVNode, render } from ‘vue‘
import XtxMessage from ‘./toast.vue‘

// 2. 准备一个DOM容器
const div = document.createElement(‘div‘)
div.setAttribute(‘class‘, ‘xtx-message-wrapper‘)
document.body.appendChild(div)

let time = null
export default ({ text, type }) => {
// 3. 创建虚拟dom (组件对象, props)
const vnode = createVNode(XtxMessage, { text, type })
// 4. 把虚拟dom渲染到div
render(vnode, div)

// 5. 设置定时器清空
clearTimeout(time)
time = setTimeout(() => {
render(null, div)
}, 1500)

console.log(‘message.js‘)
}

main.js
app.config.globalProperties.$toast = toast;
