[英]Pass data from on component to another react
I have a questionnaire and send an request to get all data back from the database, that match the answers.我有一份问卷并发送请求以从数据库中取回与答案匹配的所有数据。 I then want to use the data in another component to display the results.
然后我想使用另一个组件中的数据来显示结果。
<div className='row justify-content-end mt-3 pb-5'>
<div className='btn btn-primary btn-block rounded shadow-sm result' onClick=this.getSelectedOptions}>Ergebnisanalyse</div>
</div>
My onClick triggers the function in a class component called "ImpactAnalysis" where i get my results back as an array of objects.我的 onClick 触发了一个名为“ImpactAnalysis”的类组件中的函数,在其中我将结果作为对象数组返回。 Then i want to display the result in a class component "ResultPage"
然后我想在类组件“ResultPage”中显示结果
You can pass like this:你可以这样通过:
<ResultPage data={impactAnalysisResults} />
Then you will have this array on your ResultPage component.然后,您将在 ResultPage 组件上拥有此数组。
const ResultPage = ({data}) => {
const { impactAnalysisResults } = data;
}
Simply send those data in a component as props.只需将这些数据作为道具发送到组件中。 to send props to a component add key name and pair value with it.
向组件发送道具添加键名和配对值。 As example
例如
<ResultPage data={impactAnalysisResults} />
from ResultPage catch values like从 ResultPage 捕获值,例如
function ResultPage ({data}) {
console.log(data) //check data object sent from parent component
return (
//show your data from 'data' props
<div>{data}</div>
)
}
