‘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.

[Vue warn]: Avoid mutating a prop directly since the value will be overwritten whenever the parent .(一)
大致意思就是props接收到的从父组件传过来的tableData不能直接修改。

[Vue warn]: Avoid mutating a prop directly since the value will be overwritten whenever the parent .(二)
1.在data中声明一个变量接收props的值,然后再去改变data里的这个值 2. 用computed属性 3.用data保存数据,watch监听

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。
