【问题描述】:
我正在尝试映射以下数据并返回“余额”,但它一直告诉我“编码”未定义。
这里是数组
"entry": [
{
"resource": {
"id": "1980438",
"type": {
"coding": [
{
"system": "https://www.medeo-health.com/uploads/1/1/8/1/118121028/s491564155970805143-c3-i1-w640_orig.jpeg",
"code": "25062444",
"display": "Balance"
}
]
},
"manufactureDate": "2017-01-08",
"expirationDate": "2020-01-08",
"owner": {
"reference": "Organization/1980437"
}
},
"search": {
"mode": "match"
}
}, ...
这就是我正在尝试的:
import React, { Component } from 'react';
import Device from './Device/Device';
import axios from 'axios';
class Devices extends Component {
state = {
devices: null
}
componentDidMount() {
axios.get('http://hapi.fhir.org/baseDstu3/Device?organization=1980437&_include=Device:organization&_sort=device-name')
.then(res => {
this.setState({ devices: res.data.entry });
})
.catch(error => {
console.log(error);
})
}
render() {
let devices = <p style={{ textAlign: "left", margin: "0" }}>This practitioner have no devices!</p>;
if (this.state.devices) {
devices = this.state.devices.map(device => {
return (
<Device
key={device.resource.id}
name={device.resource.type.coding[0].display}
/>
)
});
}
return (
<div>
{devices}
</div>
);
};
};
export default Devices;
id 返回良好,但对于名称,它不断收到“无法读取未定义的属性'编码'”
我做错了什么?
【问题讨论】:
-
根据给定的信息,它找不到“类型”变量。你能创建一个沙盒给我看吗?
