vue插件--仿微信小程序showModel实现模态提示窗功能

效果图：

下面是源码：

index.js

import Vue from 'vue';
import model from './model.vue';

export default {
 install(Vue) {

 const defaults = {
  show: false,
  mask: true,
  title: '提示',
  content: '这是正文',
  confirmButton: true,
  cancelButton: true,
  confirmText: '确认',
  cancelText: '取消',
  cancelCallBack: () => {},
  confirmCallBack: () => {}
 };

 const modelVueConstructor = Vue.extend(model);

 Vue.prototype.$model = (options = {}) => {
  if (Vue.prototype.$isServer) return;
  options = Object.assign({}, defaults, options);
  let parent = document.body ;
  let instance = new modelVueConstructor({
  el: document.createElement('div'),
  data: options
  });
  parent.appendChild(instance.$el);

  return instance;
 };

 },
};

model.vue

<template>
 <div v-if="show" class="model-container">
 <div class="model-main">
  <div class="model-title">{{title}}</div>
  <div class="model-content" v-html="content"></div>
  <div class="model-buttons">
  <button v-if="cancelButton" @click="cancelClick" class="button">{{cancelText}}</button>
  <button v-if="confirmButton" @click="confirmClick" class="button confirm">{{confirmText}}</button>
  </div>
 </div>
 <div v-show="mask" class="model-mask"></div>
 </div>

</template>

<script type="text/babel">
 export default {
 data() {
 return {
 show: false,
 mask: true,
 title: '提示',
 content: '这是正文',
 confirmButton: true,
 cancelButton: true,
 confirmText: '确认',
 cancelText: '取消',
 cancelCallBack: () => {},
 confirmCallBack: () => {}
 };
 },
 methods: {
 cancelClick(){
  this.show = false;
  this.cancelCallBack();
 },
 confirmClick(){
  this.show = false;
  this.confirmCallBack();
 }
 }
 };
</script>
<style lang="less" scoped>
 .model-container{
 width: 100%;
 height: 100vh;
 position: fixed;
 top: 0;
 left: 0;
 z-index: var(--model-index);
 display: flex;
 justify-content: center;
 align-items: center;
 .model-main{
  position: relative;
  z-index: 9;
  width: 80%;
  background-color: #ffffff;
  border-radius: 10px;
  overflow: hidden;
  text-align: center;
  .model-title{
  font-size: 18px;
  color: #333;
  width: 100%;
  padding: 18px;
  font-weight: bold;
  overflow: hidden;
  white-space: nowrap;
  text-overflow: ellipsis;
  }
  .model-content{
  font-size: 16px;
  color: #666;
  padding: 10px;
  padding-top: 0px;
  padding-bottom: 20px;
  }
  .model-buttons{
  width: 100%;
  display: flex;
  align-items: center;
  .button{
   flex: 1;
   padding: 18px 10px;
   overflow: hidden;
   white-space: nowrap;
   text-overflow: ellipsis;
   font-size: 16px;
   outline: none;
   background-color: #ffffff;
   border-top: 1px solid #f2f2f2;
   border-right: 1px solid #f2f2f2;
   &.confirm{
   color: var(--theme);
   font-weight: bold;
   }
   &:last-child{
   border-right: 0;
   }
   &:active{
   background-color: #f2f2f2;
   }
  }
  }
 }
 .model-mask{
  width: 100%;
  height: 100%;
  position: absolute;
  top: 0;
  left: 0;
  z-index: 1;
  background-color: rgba(0,0,0,0.45);
 }
 }
</style>

通过添加实例方法，把插件添加到vue.prototype上来实现。

在使用之前需要将插件挂载到Vue全局实例上：

main.js

import VueModel from './components/model/index.js';
Vue.use(VueModel);

完成上述条件后，就可以在你的vue项目中使用啦：

this.$model({
 show: true,
 title: "提示",
 content: "提示内容",
 cancelButton: true,
 confirmCallBack: () => {
 console.log("确认");
 },
 cancelCallBack: () => {
 console.log("取消");
 }
});
