}報錯Warning: Cannot update during an existing state transition (such as within `render`). Render methods should be a pure function of props and state.如果是匿名函數(shù)const renderItem = (item: string, index: number) => { console.log(warpProps.handleItemDelete) return ( <List.Item>
<p onClick={() => warpProps.handleItemDelete(index)}>{item}</p>
</List.Item>
)
}報錯Lambdas are forbidden in JSX attributes due to their rendering performance impact
react - ts中，render內(nèi)不允許匿名函數(shù)，如果不使用匿名函數(shù)，則提示不允許更新state
