javascript - 过滤对象键和值

Question

我有一个看起来像这样的对象:

var myObj = {
    "account id": "123TRANS",
    "account name": "Optimus Prime",
    "creator id": "Prime",
    "contact tel": 08915243209,
    "house no": 209,
    "is registered": true,
    "price": 398.83,
    "first name": "paul",
    "last name": "jones",
    "dob": "27-Jun-1978 00:00:00",
    "previous orders": true,
    "average price": 123.78,
    "lace colour": "blue",
    "first line": "Jupiter Close",
    "city": "New York",
    "alias": "Jupiter",
    "role": "Accountant"
}

在我的 HTML 页面上，我有一个 <input>用户可以在其中输入文本的字段(至少需要 3 个字符)。我能够根据输入字符串的匹配项过滤上面的整个对象。

例如，如果 string = "Prime"响应为:

{
    "account name": "Optimus Prime",
    "creator id": "Prime",
}

例如，string = "acc"响应为:

{
    "account id": "123TRANS",
    "account name": "Optimus Prime",
    "role": "Accountant"
}

例如，string = "209"响应为:

{
    "contact tel": 08915243209,
    "house no": 209,
}

我尝试过使用.reduce ，但是这会产生不同的结果:

var myObject = {from above};
var filter = 'prime';

myObject = Object.keys(myObject).reduce((r, e) => {
    // Avoid int/float/bool and check key + value
    if(e !== 'contact tel' &&
       e !== 'house no' &&
       e !== 'previous orders') {

       // Check Key or Value for filter
       if(myObject[e].toLowerCase().includes(filter.toLowerCase) || e.toLowerCase().includes(filter.toLowerCase())) {
           r[e] = myObject[e]
       }
    }

    // Check int/float/bool and check key
    if(e === 'contact tel' ||
       e === 'house no' ||
       e === 'previous orders') {

       // Check Key or Value for filter
       if(e.toLowerCase().includes(filter.toLowerCase())) {
           r[e] = myObject[e]
       }
    }

    return r;  

}, {})

我也可以访问 lodash，但是找不到任何检查键和值的内容，只有键或值。

您可以获取条目，过滤键和值并构建一个新对象作为结果。

function find(object, search) {
    search = search.toLowerCase();
    return Object.assign(...Object
        .entries(object)
        .filter(a => a.some(s => s.toString().toLowerCase().includes(search)))
        .map(([k, v]) => ({ [k]: v }))
    );
}

var myObj = { "account id": "123TRANS", "account name": "Optimus Prime", "creator id": "Prime", "contact tel": "08915243209", "house no": 209, "is registered": true, price: 398.83, "first name": "paul", "last name": "jones", dob: "27-Jun-1978 00:00:00", "previous orders": true, "average price": 123.78, "lace colour": "blue", "first line": "Jupiter Close", city: "New York", alias: "Jupiter", role: "Accountant" };

console.log(find(myObj, 'ACC'));
