vue弹窗插件如何定义为全局的一个方法

一、在前端插件项目写一个弹窗插件（必须知道插件如何开发）

1. src/vue/modules/demo/index.js

import { install } from '../../install.js';
import index from './index.vue';
// 安装组件
install('Demo', index);

2. src/vue/modules/demo/index.vue

<template>
  <div
    v-show="showMask"
    class="dialog"
  >
    <div class="dialog-container">
      <div class="dialog-title">
        {{ title }}
      </div>
      <div
        v-html="content"
        class="content"
      />
      <div class="btns">
        <div
          v-if="type != 'confirm'"
          @click="closeBtn"
          class="default-btn"
        >
          {{ cancelText }}
        </div>
        <div
          v-if="type == 'danger'"
          @click="dangerBtn"
          class="danger-btn"
        >
          {{ dangerText }}
        </div>
        <div
          v-if="type == 'confirm'"
          @click="confirmBtn"
          class="confirm-btn"
        >
          {{ confirmText }}
        </div>
      </div>
      <div
        @click="closeMask"
        class="close-btn"
      >
        <i class="iconfont icon-close" />
      </div>
    </div>
  </div>
</template>


<script>
// import ChartBar from './components/chart-bar';

export default {
  name: 'Demo',
  components: {
  },
  props: {
    value: {},
    // 类型包括 defalut 默认， danger 危险， confirm 确认，
    type: {
      type: String,
      default: 'default',
    },
    content: {
      type: String,
      default: '内容',
    },
    title: {
      type: String,
      default: '这是标题',
    },
    cancelText: {
      type: String,
      default: '取消',
    },
    dangerText: {
      type: String,
      default: '删除',
    },
    confirmText: {
      type: String,
      default: '确认',
    },
  },
  data() {
    return {
      showMask: true,
    };
  },
  watch: {
    value(newVal, oldVal) {
      this.showMask = newVal;
    },
    showMask(val) {
      this.$emit('input', val);
    },
  },
  mounted() {
    this.showMask = true;
  },
  methods: {
    closeMask() {
      this.showMask = false;
    },
    closeBtn() {
      this.$emit('cancel');
      this.closeMask();
    },
    dangerBtn() {
      this.$emit('danger');
      this.closeMask();
    },
    confirmBtn() {
      this.$emit('confirm');
      this.closeMask();
    },
  },

};
</script>

                .default-btn{
                    color: #787878;
                    &:hover{
                        color: #509EE3;
                    }
                }
                .danger-btn{
                    background: #EF8C8C;
                    &:hover{
                        background: rgb(224, 135, 135);
                    }
                    &:active{
                        background: #EF8C8C;

                .confirm-btn{
                    color: #ffffff;
                    background: #509EE3;
                    &:hover{
                        background: #6FB0EB;
                    }
                }
            }
            .close-btn{

                text-align: center;
                font-size: 18px;
                cursor: pointer;
                &:hover{
                    font-weight: 600;
                }
            }
        }
    }
</style>

3. 在config/config/jepaas.js文件中加入组件（文件夹名称）

二.在平台挂定义一个全局方法

1.npm run dev 启动插件项目

2.开发=》全局脚本库添加数据

JE.loadScript([
      "/static/vue/demo/index.js",
      "/static/vue/demo/index.css",
    ], function() {
      //插件模板
      var tpl = '<div class="vue-box"><demo :params="params"></demo></div>';

      // 如果存在 弹窗  先清除掉
     if (document.getElementById("jevue-persion-selector")) {
        JE.removeElement(document.getElementById("jevue-persion-selector"));
      }
      //装载容器
      var id = "jevue-persion-selector";
      var div = document.createElement("div");
      div.setAttribute("id", id);
      div.innerHTML = tpl;
      var el = Ext.getBody().appendChild(div);
      var options ={};

      //载入页面
      new Vue({
        el: el.dom,
        data: function() {
          return {
            params: options,
          };
        },
      });
    }, true);

三、调用该方法

JE.callCustomFn('loadVueWin')
