javascript - 将原始 json 数据传输到 reactjs 中的 html 表

问题描述

我正在寻找一种在我的反应应用程序 https://www.depicus.com/swim-bike-run/pace-conversion-chart中显示如下图的表格的方法桌子

这是我传输到 JSON 的原始数据。 原始数据

我一直在努力解决如何在我的应用程序中显示所有数据，比如第一张图片。

这是我尝试过的代码。

        <table>
            <tbody>
                <tr>
                    {chartJSON.title.map((data, i) => <th key={i}>{data[i]}</th>)}
                </tr>
                
                {chartJSON.paceChart.map((data, index) => {
                    return <tr key={index}>{data[0]}</tr>
                })}
            
                {chartJSON.paceChart.map((data, index) => {
                    return <tr key={index}>{data[1]}</tr>
                })}
            </tbody>
        </table>

这是一些原始数据

{
"title": [
    ["KM PER HOUR", "MILES PER HOUR", "MINS PER KM", "MINS PER MILE", "5K", "10K", "HALF MARATH0N", "MARATHON"]
],
"paceChart": [
    ["7.00kph", "4.35mph", "8:34", "13:40", "00:42:51", "01:25:42", "03:00:51", "06:01:42"],
    ["7.10kph", "4.41mph", "8:27", "13:36", "00:42:15", "01:24:30", "02:58:18", "05:56:37"],
    ["7.20kph", "4.47mph", "8:20", "13:25", "00:41:40", "01:23:20", "02:55:50", "05:51:40"],
    ["7.30kph", "4.54mph", "8:13", "13:14", "00:41:05", "01:22:11", "02:53:25", "05:46:50"]
   ]
}

谁能帮我？谢谢！

解决方案

在您的 JSON 对象中，您使用的是 2D 数组。我用一维数组替换了它，因为没有必要使用二维数组。您在某些时候以错误的方式使用索引，我已经解决了这个问题。

const chartJSON = JSON.parse(`{
"title": ["KM PER HOUR", "MILES PER HOUR", "MINS PER KM", "MINS PER MILE", "5K", "10K", "HALF MARATH0N", "MARATHON"]
,
"paceChart": [
["7.00kph", "4.35mph", "8:34", "13:40", "00:42:51", "01:25:42", "03:00:51", "06:01:42"],
["7.10kph", "4.41mph", "8:27", "13:36", "00:42:15", "01:24:30", "02:58:18", "05:56:37"],
["7.20kph", "4.47mph", "8:20", "13:25", "00:41:40", "01:23:20", "02:55:50", "05:51:40"],
["7.30kph", "4.54mph", "8:13", "13:14", "00:41:05", "01:22:11", "02:53:25", "05:46:50"]
   ]
}`);

const table =
<table>
  <tbody>
     <tr>
        {chartJSON.title.map((data, i) => <th key={i}>{data}</th> )}
     </tr>
                
        {
        
        chartJSON.paceChart.map((rowData,rowIndex)=> {
           return <tr key={rowIndex}> 
             { 
             rowData.map(cellData=> <td> {cellData} </td>) 
             } 
           </tr>
          })
          
        }
           
   </tbody>
</table>

const root = document.querySelector('body');

ReactDOM.render(table,root);
td,th,table{
  text-align:center;
  border:1px solid dodgerblue;
}
