[英]How can I filter json data from api call in react into different sections of the component
I have 2 json objects that contain sales period information based on Month to data and year to date.我有 2 个 json 对象,其中包含基于月到数据和年初至今的销售期间信息。 This data includes Units Sold, Gross Revenue, Year to Date, TOTALS, Month to Date, DAILY AVGs,Expenses, Net Revenues, and PER UNIT.
此数据包括已售单位数、总收入、年初至今、总计、月初至今、每日平均数、费用、净收入和每单位。 I do not want to map this by creating a loop.
我不想通过创建一个循环来 map。 I want to take the columns out that I need and place them in different segments In the React Semantic UI code Below A big part of the reason for me not wanting to map it and do a loop is because I also want to reuse the data in a Highchart to make some pie charts.
我想取出我需要的列并将它们放在不同的段中在下面的 React Semantic UI 代码中 我不想 map 它并做一个循环的很大一部分原因是因为我也想重用数据用于制作饼图的 Highchart。 So I should be able to reuse the Data after filtering it.
所以我应该能够在过滤后重用数据。 I will be placing the values in the Headers and the
<Statistic.Value>{this.state.data.filter(item => item.match "item.gross"}</Statistic.Value>
or something like that我将把值放在标题和
<Statistic.Value>{this.state.data.filter(item => item.match "item.gross"}</Statistic.Value>
或类似的东西中
Here is my fetch这是我的获取
class FetchTest extends Component {
state = {
data: [],
loading: true,
error: false
}
componentDidMount() {
// Pick whatever host/port your server is listening on
fetch('/product/1')
.then(res => { // <-- The `results` response object from your backend
// fetch handles errors a little unusually
if (!res.ok) {
throw res;
}
// Convert serialized response into json
return res.json()
}).then(data => {
// setState triggers re-render
this.setState({loading: false, data});
}).catch(err => {
// Handle any errors
console.error(err);
this.setState({loading: false, error: true});
});
}
Here is the segments that I want to place this info in这是我要放置此信息的部分

Here is a photo of what the segments would look like这是片段看起来像的照片
I got this error when trying to filter out using const YTD = this.state.data.filter(item => this.state.data.period === 'YTD');
尝试使用
const YTD = this.state.data.filter(item => this.state.data.period === 'YTD');
and then passing <ul><li>{this.state.data}</li></ul>
然后通过
<ul><li>{this.state.data}</li></ul>
Objects are not valid as a React child (found: object with keys {period, sold, gross, cost, net, avgSold, avgGross, avgCost, avgNet, unitGross, unitCost, unitNet}). If you meant to render a collection of children, use an array instead.
in li (at FetchTest.js:45)
in ul (at FetchTest.js:44)
in div (at FetchTest.js:37)
in FetchTest (created by Context.Consumer)
in withRouter(FetchTest) (created by Context.Consumer)
in Route (at App.js:38)
in div (at App.js:24)
in Router (created by BrowserRouter)
in BrowserRouter (at App.js:23)
in App (at src/index.js:6)
This answer might not be perfect but you can do it like so.这个答案可能并不完美,但你可以这样做。
{this.state.data.map(item => {
if (item.period === 'YTD') {
Return <div>{item.gross}</div>
}
This is an example of Using map to reformat objects in an array这是使用 map 重新格式化数组中的对象的示例
