Cannot read properties of undefined (reading ‘username‘),粗心惹的祸,数据都不知道写呢了,

简介: Cannot read properties of undefined (reading ‘username‘),粗心惹的祸,数据都不知道写呢了,

       今天在敲代码的时候,遇到了一个bug:

Cannot read properties of undefined (reading 'username')

1、经过一番研究,结果竟然是数据写到了别的页面了哎

2、粗心导致的,供大家进行参考:


3、export绑定好数据就可以了

export default {
    data() {
        return {
            form: {
                username: '',
                password: '',
                repassword: ''
            }
        }
    }
}
