为什么 Map 值不显示在反应中的模态体内 bootstrap
Why Map value are not displaying inside modal body in react bootstrap
我有一个要求,当我点击一个按钮时,我应该使用 React bootstrap.
显示一个模式弹出框
But the value is not displaying inside modal body.
when I puted log, in the console it is printing all the values. But the same value I want to try to print on the modal body is not printing.
这是示例代码
`
函数 MyVerticallyCenteredModal(props) {
return(
<Modal scrollable={true}
{...props}
size="lg"
aria-labelledby="contained-modal-title-vcenter"
centered
>
<Modal.Header closeButton>
<Modal.Title id="contained-modal-title-vcenter">
Order Id - {props.order.orderId}
</Modal.Title>
</Modal.Header>
<Modal.Body>
<table>
<tbody>
{
props.order.foods.map((food,id)=>{
console.log(food);
<tr>
<td>{food}</td>
</tr>
})
}
</tbody>
</table>
</Modal.Body>
<Modal.Footer>
{/* <Button onClick={props.onHide}>Close</Button> */}
</Modal.Footer>
</Modal>
);
}`
谁能帮我解决这个问题
Thanks in advance.
你没有在你的代码中使用 return,这就是为什么你的地图没有 return 任何东西,试试这个,
<tbody>
{
props.order.foods.map((food,id)=>{
console.log(food);
return (
<tr>
<td>{food}</td>
</tr>
)
})
}
</tbody>
