antd key报错 Each child in a list should have a unique “key“ prop.

技术标签: react 项目问题  react 基础使用

使用 react + antd 组件时,有时会报出 Each child in a list should have a unique "key" prop. 这样的错误 这里列举几个相关的次错误报错和解决方式 Table 表格 解决方式:官方给 Table 组件提供了一个 rowKey 属性,用于给表格的每一行设定一个 key 值 在 antd 官方文档底下也有相关解决办法:...

Warning: Each child in a list should have a unique “key“ prop.

Warning: Each child in a list should have a uniquekeyprop. 警告:列表中每个孩子都应该一个“关键”属性。 原因: 这是由于进行组件遍历时候没一个key来进行区分每个组件,因为dom需要deff进行对比 进行循环遍历生成组件,将key设置为index即可 加在循环

Uncaught Error: Objects are not valid as a React child (found: object with keys {content, key, durat

Uncaught Error: Objects are not valid as a React child (found: object with keys {content, key, duration}). If you meant to render a collection of children, use an array instead. 我这里解决antdmessage问题

The data property "num" is already declared as a prop. Use prop default value instead.

写父组件组件相互传递数据时候,出现The data property "num" is already declared as a prop. Use prop default value instead. 这里意思是这个data属性num已经prop声明了,使用prop默认替代。因为num我组件已经创建声明后面又在子组件data 声明和初始化,冲突

The data property “xxx“ is already declared as a prop. Use prop default value instead.

Cadence元件A属性与B属性

cadence中,更改元件reference后会出现A属性和B属性 A属性为改变之前属性, B属性为改变之后属性, 如下: 如果A/B属性共存画会存在风险(导出BOM不是你需要B属性。。。) 保留B属性: 选中dsn,然后执行菜单 Accessories>Transfor Occ. prop. to Instance>Push Occ. Prop to Instance.
