我想知道如何合并和覆盖javascript中嵌套数组中已经存在的对象值。
如下所示,我需要将other_obj合并到id =“ zen”的obj,如果属性存在则覆盖,否则覆盖
var obj =[
{id:"abc",
amount: "100",
fee: "5.5"},
{id:"xyz",
amount: "1000",
fee: "5.5"},
{id:"zen",
amount: "500",
fee: "5.5"}]
var other_obj = {
amount: 600,
name: "new"
}
Expected Output:
{
id:"zen",
amount: 600,
fee: "5.5",
name: new
}
答案 0 :(得分:0)
使用...
传播语法:
var obj = [{
id: "abc",
amount: "100",
fee: "5.5"
},
{
id: "xyz",
amount: "1000",
fee: "5.5"
},
{
id: "zen",
amount: "500",
fee: "5.5"
}
];
var other_obj = {
amount: 600,
name: "new"
};
var test = {};
obj.forEach(e => test = {...test, ...e});
test = {...test, ...other_obj};
console.log(test);
