TypeError: Cannot read properties of undefined (reading 'map')
at UserList (UserList.jsx:15:23)
at renderWithHooks (react-dom.development.js:14985:18)相关代码:
function UserList({ users }) {
return (
<ul>
{users.map(user => (
<li key={user.id}>{user.name}</li>
))}
</ul>
);
}TypeError: Cannot read properties of undefined (reading 'map')
在 UserList 组件第 15 行调用 .map() 时,users 变量为 undefined。
undefined 上调用 .map() 方法users prop方案 1: 添加默认值(推荐)
function UserList({ users = [] }) {
return (
<ul>
{users.map(user => (
<li key={user.id}>{user.name}</li>
))}
</ul>
);
}方案 2: 条件渲染
function UserList({ users }) {
if (!users || users.length === 0) {
return <p>No users found</p>;
}
return (
<ul>
{users.map(user => (
<li key={user.id}>{user.name}</li>
))}
</ul>
);
}方案 3: 可选链操作符
function UserList({ users }) {
return (
<ul>
{users?.map(user => (
<li key={user.id}>{user.name}</li>
))}
</ul>
);
} interface Props {
users: User[];
} UserList.propTypes = {
users: PropTypes.array.isRequired
