您必须在调用 deleteHandler 时更新订单状态!试试这个代码!
import React from 'react';
import axios from 'axios';
// YOUR OTHER IMPORT GOES HERE
class Orders extends Component {
constructor(props) {
this.state = {
orders: [],
loading: true,
deleting: false,
}
}
componentDidMount() {
axios
.get('/order.json')
.then((res) => {
// console.log(res.data);
const fetchedOrders = [];
for (let key in res.data) {
fetchedOrders.push({ ...res.data[key], id: key });
}
this.setState({ loading: false, orders: fetchedOrders });
})
.catch((err) => {
this.setState({ loading: false });
});
}
deleteHandler = (id) => {
this.setState({
orders: this.state.orders.filter(orderValue => orderValue.id !== id)
})
axios.delete(`/order/${id}.json`).then((res) => {
this.setState({ deleting: true });
console.log(res, this.state.deleting);
});
};
render() {
return (
<div>
{this.state.orders.map((order) => (
<Order
key={order.id}
ingredients={order.ingredient}
price={order.price}
id={order.id}
delete={() => this.deleteHandler(order.id)}
/>
))}
</div>
);
}
}
