‘ref‘ is not defined.

简介: ‘ref‘ is not defined.

       有的时候,我们敲代码的时候可能会遇到'ref' is not defined.

       这里该如何解决,vue在引入ref的时候,vue2和vue3在引入的时候,需要添加import { ref } from vue,添加完毕就不会报错了

Property xxx was accessed during render but is not defined on instance
目前el-form的model主要用表单验证的,也就是配合el-form的rules和el-form-item的prop来使用的。不信的话,你可以增加一个rules和prop(为了调用验证方法,也el-form也加一个ref属性,相当于id或者class选择器的意思),但是不写model,然后验证的话,会提示缺少model,导致无法验证成功。
