javascript - 使用 Underscore.js 或 jQuery - JavaScript 按字段将对象数组转换为数组

Question

有没有办法像这样转换数组:

"team" : [   {       "player" : "John",   "rank" : 0 }, {       "player" : "Peter",   "rank" : 2 } ]

为此:

"team" : [ "John", "Peter" ]

使用 Underscore.js 还是 jQuery？

如有任何帮助，我们将不胜感激。

使用pluck :

A convenient version of what is perhaps the most common use-case for map: extracting a list of property values.

var stooges = [{name: 'moe', age: 40}, {name: 'larry', age: 50}, {name: 'curly', age: 60}];
_.pluck(stooges, 'name');
=> ["moe", "larry", "curly"]
