下划线 JS 查找对象

Question

我有一个如下的数组

var goal  = [

    {
        "category" : "education",
        "title" : "Charlie University",
        "description" : "Lorem ipsum dolor sit amet",
        "date" : "01/03/2020",
        "value" : 50000,
        "achievability" : 3,
        "experimental_achievability": 3,
        "designation": "{"id":1, "jobCode":1003}",
        "suggested": false,
        "accounts": [],
        "articles": [],
        "related_goals": [],
        "id":"1"
    },
    {
        "category" : "education",
        "title" : "Charlie University",
        "description" : "Lorem ipsum dolor sit amet",
        "date" : "01/03/2020",
        "value" : 50000,
        "achievability" : 3,
        "experimental_achievability": 3,
        "designation": "{"id":2, "jobCode":1004}",
        "suggested": false,
        "accounts": [],
        "articles": [],
        "related_goals": [],
        "id":"2"
    },
    ]

如何使用下划线 JS 从目标数组中获取具有属性 "designation": "{"id":2, "jobCode":1004}", 的对象。

我可以使用 _.findWhere 吗？

Answer 1

你不需要下划线，你可以使用 Array.find

goal.find(function(item) {
  return item.id === 2 && item.jobCode === 1004
})

es2015 示例：

goal.find(item => item.id === 2 && item.jobCode === 1004)
