【问题描述】：

嗨，我有一组对象试图使用 discord 制作聊天机器人，所以在某些情况下，一个输入给我的不仅仅是输出，但我很挣扎，这是我的数组

let message = [
        "message": "hi",
        "reply": "1-order 2-inquiry 3-complain"
    ,

    
        "message": "1",
        "reply": "please clarify your address"
    ,

    
        "message": "2",
        "reply": "about 1-delivery time 2-delivery fees",
        "response": 
            "1": "from 8 am to 11 pm",
            "2": "10$"
        
    ,

    
        "message": "3",
        "reply": "1-expired products 2-other",
        "response": 
            "1": "please clarify the product name ",
            "2": "please leave a comment"
        
    
]

这里的问题是我如何指定当我输入 1 时聊天机器人将响应那个特定的回复，这意味着一个输入有很多输出，所以我该如何做这个

非常感谢。

【参考方案1】：

您可以使用Array.find 返回数组中与我们的条件匹配的第一项。 我们可以这样实现

const input = '1'; // we assume the input was '1'

const output = message.find(q => 
    return (q.message === input);
);

console.log(output.reply);

来，试试看

let message = [
  
    "message": "hi",
    "reply": "1-order 2-inquiry 3-complain"
  ,

  
    "message": "1",
    "reply": "please clarify your address"
  ,

  
    "message": "2",
    "reply": "about 1-delivery time 2-delivery fees",
    "response": 
        "1": "from 8 am to 11 pm",
        "2": "10$"
    
  ,

  
    "message": "3",
    "reply": "1-expired products 2-other",
    "response": 
        "1": "please clarify the product name ",
        "2": "please leave a comment"
    
  
];

const input = '1'; // we assume the input was '1'

const output = message.find(q => 
    return (q.message === input);
);

console.log(output.reply);
