封装JS

import Vue from 'vue'
import customDialog from '@/components/dialog/customDialog'

//  生成类
const dialogConstrutor = Vue.extend(customDialog)

//  将组件挂在到Vue原型链
const createDialogDom = (options) => {
    return new Promise((resolve, reject) => {
        //  创建实例
        const currtent = new dialogConstrutor({
            //  将实例挂在到div元素
            el: document.createElement('div')
        })
        currtent.title = options.title || '提示'
        currtent.message = options.message || 'd窗内容'
        currtent.showCancelButton = options.showCancelButton || false
        currtent.showConfirmButton = options.showConfirmButton || true
        currtent.cancelButtonText = options.cancelButtonText || '取消'
        currtent.confirmButtonText = options.confirmButtonText || '确定'
        currtent.dangerouslyUseHTMLString = options.dangerouslyUseHTMLString || false
        currtent.show = true
    
        //  将实例元素挂在到全局挂载点
        document.body.appendChild(currtent.$el)
        
        currtent.confirm = () => {
            resolve();
            currtent.show = false
        }
        
        currtent.cancle = () => {
            reject()
            currtent.show = false
        }
        
        currtent.close = () => {
            reject()
            currtent.show = false
        }
    })
}

/*//  将组件挂载到Vue原型链
const CustomDialog = () => {
    Vue.prototype.$customdialog = createDialogDom
}*/

export default createDialogDom

在main.js中引用

//  导入自定义d窗组件
import CustomDialog from './components/dialog/customDialog'

import customdialog from './utils/packageInstall/custom-dialog'

Vue.component('CustomDialog',CustomDialog)
Vue.prototype.$customdialog = customdialog
