Array to string with AngularJS and Lodash
提问by Eric Mitjans
I have an array ($scope.paxlist) looking like this:
我有一个如下所示的数组 ($scope.paxlist)：
[
{"name":"Maria","chosen":false},
{"name":"Jenny","chosen":false},
{"name":"Ben","chosen":false},
{"name":"Morris","chosen":false}
]
I need to take only the values from nameand convert them into a string in order to be able to use ng-CSV properly.
The desired output would be something like this:
我只需要从中获取值name并将它们转换为字符串，以便能够正确使用 ng-CSV。所需的输出将是这样的：
$scope.var = "Maria, Jenny, Ben, Morris"
Taking into consideration that I have Angular and Lodash already loaded, could anybody point out if they have already some tool to do this painlessly?
考虑到我已经加载了 Angular 和 Lodash，有人能指出他们是否已经有一些工具可以轻松地做到这一点吗？

Using native mapof javascript you can do it as bellow
使用JavaScript 的原生地图，您可以按照以下方式进行
var data = [
{"name":"Maria","chosen":false},
{"name":"Jenny","chosen":false},
{"name":"Ben","chosen":false},
{"name":"Morris","chosen":false}
];
data.map(function(obj){return obj.name;}).join(', '); // returns the expected output.
Using Lodash
使用 Lodash
_.map(data,'name').join(', ')

By using Mrityunjay's answer, this is another version of the answer to convert array of string to string:
通过使用 Mrityunjay 的答案，这是将字符串数组转换为字符串的另一个版本的答案：
const _ = require('lodash');
const data = ['abc','xyz','123'];
const translated = _.map(data).join(', ');
console.log(`result: ${translated}`);
