将对象的属性转换为逗号分隔的列表?

I have an object like this:

我有这样一个对象:

var person = {
  name: "John",
  surname: "Smith",
  phone: "253 689 4555"
}

I want:

我想要:

John,Smith,253 689 4555

Is there some easy way?

有什么简单的方法吗?

If possible, could you please provide an example where I can also define the separator?

如果可能的话，您能否提供一个例子，我也可以定义分离器?

7 个解决方案

#1

You can use this one-liner in modern browsers

您可以在现代浏览器中使用这一行代码

Object.keys(person).map(function(k){return person[k]}).join(",");

#2

Write a function like this:

编写这样的函数:

function toCSV(obj, separator) {
    var arr = [];

    for (var key in obj) {
        if (obj.hasOwnProperty(key)) {
            arr.push(obj[key]);
        }
    }

    return arr.join(separator || ",");
}

And then you can call it like:

然后你可以这样称呼它:

toCSV(person, "|"); // returns "John|Smith|253 689 4555"

或

toCSV(person); // returns "John,Smith,253 689 4555"

#3

try this:

试试这个:

var key,
  person = {
    name: "John",
    surname: "Smith",
    phone: "253 689 4555"
  },
  array = [];

for ( key in person ) {
  if ( person.hasOwnProperty( key ) ) {
    array.push( person[ key ] );
  }
}

console.log( array.join( ',' ) );

or in function style:

或函数风格:

var
  getValues = function ( obj ) {
    var key,
      array = [];

    for ( key in obj ) {
      if ( obj .hasOwnProperty( key ) ) {
        array.push( obj [ key ] );
      }
    }

    return obj.join( ',' );
  };

var person = {
      name: "John",
      surname: "Smith",
      phone: "253 689 4555"
    };

console.log( getValues( person ) );

You might want to try this library - Underscore.js. It gives you really helpful methods and works across browsers.

您可能想尝试这个库- Underscore.js。它提供了非常有用的方法，可以跨浏览器工作。

Here you can do it like this -

你可以这样做

_.values(person).join(",")

或

_.values(person).join("|")

#5

Object.values(person).join('/')

#6

Here is a simpler one liner. It uses the Object.values() method instead of Object.keys

这是一个比较简单的。它使用Object.values()方法而不是Object.keys

Object.values(obj).join(",");

#7

Another way is to use lodash function _.toString()

另一种方法是使用lodash函数_.toString()

console.log( _.toString( Object.values( person ) ) );
==> John,Smith,253 689 4555
