更新某些對象屬性

Question

我有這樣的事情：

let test = [ 
      { 
       name: "Mark", 
       address: "Some adress", 
       company: "company name", 
       age: 21 
      } 
] 

let test1 = [ 
      { 
       name: "Steve", 
       age: 27 
      } 
    ] 

如何我test1的更新測試？因此，我想要得到的是：

let test2 = [ 
      { 
       name: "Steve", 
       address: "Some adress", 
       company: "company name", 
       age: 27 
      } 
] 

Answer 1

您可以使用它Object.assign。

的Object.assign()方法用於從一個或多個源對象中所有可枚舉自己的屬性的值複製到目標對象。它會返回目標對象。

let test = [{ name: "Mark", address: "Some adress", company: "company name", age: 21 }], 
 
    test1 = [{ name: "Steve", age: 27 }]; 
 

 
Object.assign(test[0], test1[0]); 
 

 
console.log(test);

Answer 2

你可以這樣做：

test[0].name = test1[0].name; 
test[0].age = test1[0].age; 

其實，你並不需要把對象作爲一個數組。就像這樣：

let test = { 
     name: "Mark", 
     address: "Some adress", 
     company: "company name", 
     age: 21 
} 

這樣，你不需要調用它像這樣：test[0].name - >只是做test.name
