element ui中的message弹出框只出现一次

import { Message } from 'element-ui';
let messageInstance = null;
const resetMessage = (options) => {
    if(messageInstance) {
        messageInstance.close()
    }
    messageInstance = Message(options)
};
['error','success','info','warning'].forEach(type => {
    resetMessage[type] = options => {
        if(typeof options === 'string') {
            options = {
                message:options
            }
        }
        options.type = type
        return resetMessage(options)
    }
})
export const message = resetMessage

建立js文件

import { message } from '../../utils/resetMessage';

引入js文件

 message.error(errorMsg || '网络异常请稍后再试', '错误');

使用即可
