1. 组件效果展示
2. 结构及功能代码
<template>
<div class="xtx-confirm" :class="{ fade }">
<div class="wrapper" :class="{ fade }">
<div class="header">
<h3>{{ title }}</h3>
<a
@click="cancelCallback()"
href="JavaScript:;"
class="iconfont icon-close-new"
></a>
</div>
<div class="body">
<i class="iconfont icon-warning"></i>
<span>{{ text }}</span>
</div>
<div class="footer">
<XtxButton @click="cancelCallback()" size="mini" type="gray"
>取消</XtxButton
>
<XtxButton @click="submitCallback()" size="mini" type="primary"
>确认</XtxButton
>
</div>
</div>
</div>
</template>
<script>

3. 参数说明
title:自定义弹出窗标题
text:自定义弹窗内容
submitCallback:点击弹窗确定按钮的回调
cancelCallback:点击弹窗取消按钮的回调
4. 组件的使用
因为需要操作dom元素在页面中动态添加移除,将具体操作移至单独的js文件中
具体内容如下:
// 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-----
// 点击确定或取消都要隐藏Dom
import { createVNode, render } from 'vue'
import XtxConfirm from './xtx-confirm.vue'
// 准备dom容器
const div = document.createElement('div')
document.body.appendChild(div)
export default ({ title, text }) => {
return new Promise((resolve, reject) => {
// 点击确定,关闭组件
const submitCallback = () => {
render(null, div)
resolve()
}
// 点击取消,关闭组件
const cancelCallback = () => {
render(null, div)
reject(new Error('取消'))
}
const vnode = createVNode(XtxConfirm, { title, text, submitCallback, cancelCallback })
render(vnode, div)
})
}
使用时:需要引入js文件
import confirm from './confirm.js'
confirm({ title: '系统提示', text: '确认要删除吗?' }).then(() => {
// 点击确认之后要做的事情
}).catch(() => {
// 点击了取消
})
