【问题描述】：

假设我有一个对象数组：

它将多个值存储在一个变量中。该对象可以包含用户名、金额等。 实际上，我将数据的相同对象存储在单个对象中，就像描述中的定义一样。 所以，帮助我每个人都可以解决这个问题。 请解决这个问题。

        "id": 2,
        "Username": "Rajesh",
        "Amount": "3000",

        "Amount": "2000",
        "Account_name": "Rahul",

    ,
    
        "id": 10,

        "id": 11,

        "Amount": "2000",
        "Account_name": "xyz",
        "Google_pay": "9794368090",

        "Date": "2021-12-16T13:51:20.000Z"
    ,
    
        "id": 14,
        "Username": "rajesh",
        "Amount": "1200",

        "Ifsc": "",
        "Date": "2021-12-17T08:42:17.000Z"

However, I can't seem to get an array that looks like this

```
    "john$123": [
        
            "id": 3,
            "Username": "john$123",

I have been able to make some sort of headway, but can not quite get the exact result I need. Any guidance is greatly appreciated, thanks!

【问题讨论】：

如果您分享一些示例并尝试一些东西会很好。并在 js fiddle 中分享

【参考方案1】：

不确定我的理解是否正确，但您只是想为具有特定用户名的用户获取正确的信息？

如果是这样，那么您可以在您的第一个对象上使用 .filter()，如下所示

let array = [] //your original array
let username = "rajesh" //the username whose info you want to get
let userData = array.filter(results => results.Username.toLowerCase() === username.toLowerCase())
console.log(userData) //this will contain all the elements that had their username the same as the username in the username variable (case insensitive)

//do stuff with the new filtered user data

现在，如果您希望数据为 json，键为用户名，您可以这样做

let returnData = 
returnData[username] = userData
return returnData
