將鍵值對添加到所有對象

Question

我是Spring的新成員，我將一個對象轉換爲json以用於jsp頁面。 json對象看起來像下面。

[ 
    {"year":2014,"average":115.5}, 
    {"year":2016,"average":0.0}, 
    {"year":2017,"average":8.28}, 
    {"year":2018,"average":0.0} 
] 

我需要另一個關鍵值對（「顏色」：值）添加每個對象像下面給出。

[ 
    {"year":2014,"average":115.5,"color":1}, 
    {"year":2016,"average":0.0,"color":2}, 
    {"year":2017,"average":8.28,"color":3}, 
    {"year":2018,"average":0.0,"color":4} 
] 

現在我傳到頁面，如何將這個鍵值對添加到每個對象在JavaScript中？

Answer 1

添加到您現有的對象，像這樣：

var yourNewArray = yourOriginalArray.map(function(obj) { 
    var me = Object.assign({}, obj); 
    me.color = 'yourNewColorValue'; 
    return me; 
});
