javascript - 获取第一个数组中具有 id 的对象与 java 脚本中其他数组的对象中的 id 相同

Question

我有 2 个对象数组。他们是

array1 = [{
  id:2,
  name:"person2"
},{
  id:3,
  name:"person3"
},
{
  id:4,
  name:"person4"
},
{
  id:5,
  name:"person5"
},
];
array2 = [
{
    empId:2,
    isdeleted:false
},
{
    empId:4,
    isdeleted:false
}, 
{   
    empId:3,
    isdeleted:true
}];

我需要来自 array1 的对象，其 id 与 array2 的 empId 匹配并且 isdeleted 为 false。提前致谢。

您可以使用 filter和 some像这样:

let array1 = [{
    id: 2,
    name: "person2"
  }, {
    id: 3,
    name: "person3"
  },
  {
    id: 4,
    name: "person4"
  },
  {
    id: 5,
    name: "person5"
  },
];

let array2 = [{
    empId: 2,
    isdeleted: false
  },
  {
    empId: 4,
    isdeleted: false
  },
  {
    empId: 3,
    isdeleted: true
  }
];

let filteredArray = array1.filter(a => array2.some(b => b.empId === a.id && !b.isdeleted));
console.log(filteredArray);
