Lodash 在数组中查找数组

Question

我有一个如下所示的数组:

   var roles = [ 
           { "label": "Super Auditor", "value": 4 }, 
           { "label": "Super Finance Officer", "value": 3 }, 
           { "label": "Super Manager", "value": 2 }, 
           { "label": "Super Admin", "value": 1 } 
   ]

我需要查找它是否在数组中并获取该对象。

var needToFind = [4, 1]

预期结果:

var results =[
              { "label": "Super Auditor", "value": 4 }, 
              { "label": "Super Admin", "value": 1 } 
            ]

我只是不知道该怎么做。 TY

Answer 1

您可以使用 _.intersectionWith() :

var roles = [ 
  { "label": "Super Auditor", "value": 4 }, 
  { "label": "Super Finance Officer", "value": 3 }, 
  { "label": "Super Manager", "value": 2 }, 
  { "label": "Super Admin", "value": 1 }
]

var needToFind = [4, 1]

var result = _.intersectionWith(roles, needToFind, (a, b) => a.value === b)

console.log(result)
