使用基于属性值的 lodash 过滤对象数组 [英] Filtering array of objects with lodash based on property value

问题描述

我们有一个这样的对象数组

We have an array of objects as such

var myArr = [ {name: "john", age: 23},
              {name: "john", age: 43},
              {name: "jim", age: 101},
              {name: "bob", age: 67} ];

如何从 myArr 中获取名称为 john 和 lodash 的对象列表?

how do I get the list of objects from myArr where name is john with lodash?

推荐答案

Lodash 有一个地图"功能，就像 jQuery 一样工作:

Lodash has a "map" function that works just like jQuerys:

var myArr =  [{ name: "john", age:23 },
              { name: "john", age:43 },
              { name: "jimi", age:10 },
              { name: "bobi", age:67 }];

var johns = _.map(myArr, function(o) {
    if (o.name == "john") return o;
});

// Remove undefines from the array
johns = _.without(johns, undefined)
