用法

this.$dialog.show({
  title: "Dialog",
  width: "50%",
  data: { name: "name", age: 18 }, // 非编辑时此项可省略
  option: {
    confirmText: "保存", // 可省
    columns: [
      {
        label: "姓名",
        prop: "name",
        rules: [
          {
            required: true,
            message: "请输入姓名",
            trigger: "blur",
          },
        ],
      },
      {
        label: "年龄",
        prop: "age",
      },
    ],
  },
  beforeCancel: (done) => {
    done();
  },
  confirmHandle: (res) => {
    console.log('$dialog.confirm', res.data);
    this.$message.success("点击了确认按钮,即将关闭窗口");
    setTimeout(() => {
      this.$message.success("业务逻辑已执行完成,关闭窗口");
      res.close();
    }, 1000);
  },
});

方法

/src/main.js

import dialog from './components/dialog'
Vue.prototype.$dialog = dialog;

/src/components/dialog/index.js

import Vue from 'vue';
import DialogComponent from './index.vue';
let Plugin = function () {
  this.$root = {};
};

  this.$root = (() => {
    let DialogConstructor = Vue.extend(DialogComponent);
    let instance = new DialogConstructor();
    instance.vm = instance.$mount();
    document.body.appendChild(instance.vm.$el);
    instance.dom = instance.vm.$el;
    return instance.vm;
  })();
};
Plugin.prototype.show = function (opt) {
  this.initMounted();
  this.$root.show(opt);
};
export default new Plugin();
