我在我的 redux 存盤中有一個名為“value”的物件陣列，我是通過在每次行程開始和停止時向其添加開始時間/結束時間來新創建的。看起來像這樣
const value = [
{startTime:1635926165, name:"dailyScripts", endTime:1635926189},
{startTime:1635926125, name:"datawarehouse", endTime:1635926125},
{startTime:1234567890, name:"dummp", endTime:1234567890}
]
我在“本地狀態”中有另一個物件陣列，稱為串列，其中包含所有資料。這里我想給每個同名的obj加上開始時間和結束時間。
const list = [
{pid: 248, name: 'dailyScripts', pm2_env: {…}, pm_id: 2, monit: {…}}
{pid: 259, name: 'datawarehouse', pm2_env: {…}, pm_id: 2, monit: {…}}
{pid: 0, name: 'dump', pm2_env: {…}, pm_id: 2, monit: {…}}
]
所以我的最終輸出應該是這樣的 -
const list = [
{pid: 248, name: 'dailyScripts',...otherObjs, startTime:1635926165, endTime:1635926189}
{pid: 259, name: 'datawarehouse',...otherObjs, startTime:1635926125, endTime:1635926125}
{pid: 0, name: 'dump',...otherObjs, startTime:1635926165, endTime:1635926189}
]
我如何使用 React 解決這個問題？我想改變串列狀態或將值 arr 與串列 arr 合并。

嘗試這個 ：
const value = [
{ startTime: 1635926165, name: "dailyScripts", endTime: 1635926189 },
{ startTime: 1635926125, name: "datawarehouse", endTime: 1635926125 },
{ startTime: 1234567890, name: "dummp", endTime: 1234567890 }
];
const list = [
{ pid: 248, name: 'dailyScripts', pm2_env: {}, pm_id: 2, monit: {} },
{ pid: 259, name: 'datawarehouse', pm2_env: {}, pm_id: 2, monit: {} },
{ pid: 0, name: 'dump', pm2_env: {}, pm_id: 2, monit: {} }
];
let output = [];
list.forEach(e => {
let valueTime = value.find(ee => ee.name === e.name);
if (valueTime) {
output.push({...e, startTime : valueTime.startTime, endTime : valueTime.endTime });
} else {
output.push({...e});
}
});
console.log(output);轉載請註明出處，本文鏈接：https://www.uj5u.com/qiye/346272.html
