我有這個物件
const a = {
elementErrors: {
errorMessages: [],
errors: {
project: "Issues with this Issue Type must be created in the same project as the parent."
}
},
issueKey: "JP-55",
status: 400
}
我想對其進行變異，以便嵌套專案屬性在字串末尾包含 issueKey 屬性，例如"Issues with this Issue Type must be created in the same project as the parent (JP-55)."
我知道我應該表明我嘗試過并且我做到了，但我還沒有設法開始解決方案。
最終物件將如下所示：
const a = {
elementErrors: {
errorMessages: [],
errors: {
project: "Issues with this Issue Type must be created in the same project as the parent (JP-55)."
}
},
issueKey: "JP-55",
status: 400
}
非常感謝

您可以使用 =運算子將??某些內容“添加”到字串的末尾。
a.elementErrors.errors.project = ` (${a.issueKey})`;
let a = {
elementErrors: {
errorMessages: [],
errors: {
project: "Issues with this Issue Type must be created in the same project as the parent."
}
},
issueKey: "JP-55",
status: 400
}
a.elementErrors.errors.project = ` (${a.issueKey})`;
console.log(a);uj5u.com熱心網友回復：
您想根據其他一些值計算新屬性。只需嘗試訪問并覆寫它。
如果末尾總是有一個點，則可以混合使用split()和template literals。
const a = {
elementErrors: {
errorMessages: [],
errors: {
project: "Issues with this Issue Type must be created in the same project as the parent."
}
},
issueKey: "JP-55",
status: 400
}
a.elementErrors.errors.project = `${a.elementErrors.errors.project.split('.')[0]} (${a.issueKey}).`;
console.log(a);PS：如果沒有，上面的代碼會中斷.
