1-封装模态框组件Mydialog (样式可以自己写)

<template> <transition name="modal" tag="div"> <div class="modal" v-show="visible" transition="fade"> <div class="modal-dialog"> <div class="modal-content"> <!--头部--> <div class="modal-header"> <slot name="header"> <!-- <p class="title">{{modal.title}}</p> --> </slot> <a @click="close(0)" class="xd xd-close" href="javascript:void(0)" rel="external nofollow" rel="external nofollow" rel="external nofollow" ></a> </div> <!--内容区域--> <div class="modal-body"> <slot name="body"> </slot> </div> <!--尾部,操作按钮--> <div class="modal-footer"> <slot name="footer"> <slot name="button" class="footer">> <a v-if="modal.showCancelButton" href="javascript:void(0)" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="button" :class="modal.cancelButtonClass" @click="close">{{modal.cancelButtonText}}</a> <a v-if="modal.showConfirmButton" href="javascript:void(0)" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="button" :class="modal.confirmButtonClass" @click="close()">{{modal.confirmButtonText}}</a> </slot> </slot> </div> </div> </div> </div> <!-- <div v-show="show" class="modal-backup"></div> --> </transition></template><script>export default { props: { visible: { type: Boolean, default: false }, options: { type: Object, default: {} } }, // 采用v-bind将visible传入 methods: { ConfirmHandler () { this.$emit('update:visible', false); // 更新visible的值（可选，如果想点击确认之后，进行一些处理再决定关不关闭，可取消在这里更新visible） this.$emit('Confirm'); // 传递确认事件 }, CancelHandler () { this.$emit('update:visible', false); // 更新visible的值 this.$emit('Cancel'); // 传递取消事件 }, close () { this.visible = false; } }, /** * modal 模态接口参数 * @param {string} modal.title 模态框标题 * @param {boolean} modal.showCancelButton 是否显示取消按钮 * @param {string} modal.cancelButtonClass 取消按钮样式 * @param {string} modal.cancelButtonText 取消按钮文字 * @param {string} modal.showConfirmButton 是否显示确定按钮 * @param {string} modal.confirmButtonClass 确定按钮样式 * @param {string} modal.confirmButtonText 确定按钮标文字 */ computed: { /** * 格式化props进来的参数,对参数赋予默认值 */ modal () { let modal = this.options; if (modal) { modal = { title: modal.title || '提示', showCancelButton: typeof modal.showCancelButton == 'undefined' ? true : modal.showCancelButton, cancelButtonClass: modal.cancelButtonClass ? modal.showCancelButton : 'btn-default', cancelButtonText: modal.cancelButtonText ? modal.cancelButtonText : '取消', showConfirmButton: typeof modal.showConfirmButton == 'undefined' ? true : modal.cancelButtonClass, confirmButtonClass: modal.confirmButtonClass ? modal.confirmButtonClass : 'btn-active', confirmButtonText: modal.confirmButtonText ? modal.confirmButtonText : '确定', }; } else { // 使用时没有传递参数 modal = { title: '提示', showCancelButton: true, cancelButtonClass: 'btn-default', cancelButtonText: '取消', showConfirmButton: true, confirmButtonClass: 'btn-active', confirmButtonText: '确定', }; } return modal; }, },}</script><style lang="scss" scoped>.modal-enter-active { animation: modal-in 0.35s linear;}.modal-leave-active { animation: modal-in 0.35s reverse linear;}@keyframes modal-in { 0% { transform: translateY(-20px) rotateX(-35deg); opacity: 0; } 50% { opacity: 0.5; } 100% { transform: translateY(0) rotateX(0); opacity: 1; }}.modal { width: 100%; height: 100%; position: fixed; left: 0; top: 0; right: 0; bottom: 0; z-index: 1001; outline: 0; overflow: hidden; background-color: rgba(0, 0, 0, 0.8);}.modal-dialog { position: absolute; left: 50%; top: 50%; transform: translate(-50%, -50%); width: auto; width: 608px; background: #fff; border-radius: 20px; box-shadow: 0 8px 24px 7px rgba(0, 0, 0, 0.11); z-index: 1002; overflow: hidden; .modal-content { > div { // padding: 0.15rem 0.4rem; } .modal-header { background: url("../assets/images/tournaments/1.png") no-repeat; background-size: cover; height: 70px; img { width: 100%; } } .modal-body { // padding: 90px 0 72px 0; color: #3c3c43; font-size: 25px; border-bottom: 1px solid #bdbdbd; font-weight: 500; } .footer { a { font-size: 30px; color: #2c2c2c; } } .modal-footer { padding: 30px 0 40px 0; color: #3c3c43; font-size: 30px; font-weight: 500; } }}.modal-backup { width: 100%; height: 100%; position: fixed; top: 0; right: 0; bottom: 0; left: 0; z-index: 1000; background: rgba(0, 0, 0, 0.5);}</style>

2-使用方法1

页面中引入在进行调用

(1) import Mydialog from '../carrer/mydialog.vue';

(2)引入组件

components: { Mydialog }

(3 在html中插入组件

<Mydialog v-show="isShowDialog" :dialog-option="dialogOption" ref="mydialog"></Mydialog>

data中的参数

showDialog: false, dialogOption: { text: '欢迎', cancelButtonText: '否', confirmButtonText: '是', isShowCancelButton: '' },

methods中 在需要出现弹框时候让其显示就好啦

showDialog() this.dialogOption.text = ` <p>确认拒绝？</p> `; this.dialogOption.isShowCancelButton = true this.showDialog = true; this.$refs.mydialog.confirm().then(() => { this.showDialog = false; this.refuse(id) }).catch(() => { this.showDialog = false; }) },

3.使用方法2

因为在项目中经常要使用到，而且每次使用的时候都要带上相同的参数，所以就封装了一个js，（模态框的工具类），使用的时候调用就好了

1)- 新建一个js文件dialogUtil，复制下面的代码就好了

class normalDialog { constructor(args) { // console.log("args",args); this.parent = args.parent; this.isShowDialog = args.isShowDialog; this.dialogOption = this.parent[args.dialogOption]; this.mydialog = this.parent.$refs[args.mydialog]; // console.log("dialogOption=",this.dialogOption); } showDialog(text, showCancelButton, success, error) { console.log("showDialog=="+text); this.dialogOption.text = text || "请输入弹框标题"; let suc = typeof showCancelButton == "function" ? showCancelButton : success; let err = typeof showCancelButton == "function" ? success : error; if (typeof showCancelButton != "function") { this.dialogOption.isShowCancelButton = !!showCancelButton; } else { this.dialogOption.isShowCancelButton = true; } this.parent[this.isShowDialog] = true; this.confirm(suc, err); } //弹框回调 confirm(success, error) { let self = this; this.mydialog.confirm().then(() => { typeof success == "function" && success(); self.parent[this.isShowDialog] = false; }).catch(() => { typeof error == "function" && error(); self.parent[this.isShowDialog] = false; }) } toString() { // console.log(this.name + " : " + this.age); }}export default { //args：参数， 类型 creatByType(args, type) { type = !!type ? type : 1; switch (type) { case 1: return new normalDialog(args) break; case 2: break default: break; } }}

2) 因为很多页面都用到，所以让他成为全局的（在main中引入就好了），那么别的页面使用就不需要引入了

import dbDiaLogUtil from './assets/js/dialogUtil'Vue.prototype.$dbDiaLogUtil = dbDiaLogUtil;

3)在使用的时候

页面中引入组件在进行调用

(1) import Mydialog from '../carrer/mydialog.vue';

(2)引入组件

components: { Mydialog }

（3） 在html中插入组件

<Mydialog v-show="isShowDialog" :dialog-option="dialogOption" ref="mydialog"></Mydialog>

在data（）中用对象的形式

isShowDialog : false, dialogOption:{text: '',cancelButtonText: '否',confirmButtonText: '确认',isShowCancelButton: false}, dialogNormal:null,

在mounted中进行初始化

this.dialogNormal = this.$dbDiaLogUtil.creatByType({parent:this,isShowDialog:'isShowDialog',dialogOption:'dialogOption',mydialog:'mydialog'});

最后在需要弹框的地方调用，一句代码搞定啦

this.dialogNormal.showDialog('dialog要显示的内容',function(){console.log('成功执行的')} , function(){console.log('失败执行的')})
