我的問題是如何用來自客戶端的新值替換 version[1].data[] ..

新數據看起來像

"data": [
            {
                "totalResources": 4,
                "costToCompany": 2200,
                "profitToCompany": 1100,
                "costToClient": 3300,
                "resources": [
                    {
                        "genericDesignationName": "Development",
                        "designationName": "Backend Developer",
                        "departmentName": "web development",
                        "calculationFactor": 1,
                       
                    },
                    {
                        "genericDesignationName": "Development",
                        "designationName": "Frontend Developer",
                        "departmentName": "web development",
                        "calculationFactor": 1,
                        
                    }
                ],
                "addOns": [
                    {
                        "genericDesignationName": "Design",
                        "designationName": "Graphic Designer",
                        "addOnCost": 100,
                       
                    }
                ],
                               }
        ],
        
    }
]

您可以通過迭代versions數組來簡單地實現這一點：

 const data = { versions: [{ ver: 0, data: [] }, { ver: 1, data: [] }, { ver: 2, data: [] }] }; const replacedData = ['abc']; data.versions.forEach(obj => { if (obj.ver === 1) { obj.data = replacedData } }); console.log(data);
