vue2.0 自定义 弹窗（MessageBox）组件

组件模板

src/components/MessageBox/index.vue

给组件添加全局功能

src/components/MessageBox/index.js

import msgboxVue from './index.vue';

// 定义插件对象
const MessageBox = {};
// vue的install方法，用于定义vue插件
MessageBox.install = function (Vue, options) {
  const MessageBoxInstance = Vue.extend(msgboxVue);
  let currentMsg;
  const initInstance = () => {
    // 实例化vue实例
    currentMsg = new MessageBoxInstance();
    let msgBoxEl = currentMsg.$mount().$el;
    document.body.appendChild(msgBoxEl);
  };
  // 在Vue的原型上添加实例方法，以全局调用
  Vue.prototype.$msgBox = {
    showMsgBox (options) {
      if (!currentMsg) {
        initInstance();
      }
      if (typeof options === 'string') {
        currentMsg.content = options;
      } else if (typeof options === 'object') {
        Object.assign(currentMsg, options);
      }
      return currentMsg.showMsgBox()
        .then(val => {
          currentMsg = null;
          return Promise.resolve(val);
        })
        .catch(err => {
          currentMsg = null;
          return Promise.reject(err);
        });
    }
  };
};

export default MessageBox;

全局使用

src/main.js

import MessageBox from './components/MessageBox/index';
Vue.use(MessageBox);

页面调用

test.vue
