let selectIds = [1, 3] // 选中id数组
    let allData = [
      { id: 1, name: '123' },
      { id: 2, name: '234' },
      { id: 3, name: '345' },
      { id: 4, name: '456' },
    ] // 源数据
    let newList = [] // 最终数据
    selectIds.map((i) => {
      allData.filter((item) => {
        item.id == i && newList.push(item)
      })
    })
    console.log("🚀 ~ handlerAdd ~ newList:", newList)

结果：

若是根据后端id数组转换name展示只需在newList.push(item.name)
