let curr_data_list = [{
                            warehouse_id: "1",
                            wg_id: "111"
                        },{
                            warehouse_id: "2",
                            wg_id: "222"
                        },{
                            warehouse_id: "3",
                            wg_id: "333"
                        },{
                            warehouse_id: "4",
                            wg_id: "444"
                        }]
let wg_ids_arr = [222,55,444,66,77]

我有上面两个数组，我想通过wg_ids_arr 的值，去和curr_data_list做判断，

如果curr_data_list 的wg_id值，存在wg_ids_arr 数组里，当前项就增加一个属性is_selector_val:true 否则 is_selector_val:false

下面就是我想要的数据：

let curr_data_list = [{
                            warehouse_id: "1",
                            wg_id: "111",
                            is_selector_val:false
                        },{
                            warehouse_id: "2",
                            wg_id: "222",
                            is_selector_val:true
                        },{
                            warehouse_id: "3",
                            wg_id: "333",
                            is_selector_val:false
                        },{
                            warehouse_id: "4",
                            wg_id: "444",
                            is_selector_val:true
                        }]

想请问下，怎么写，谢谢大家

回答：

curr_data_list.map(item=>{
    item.is_selector_val = wg_ids_arr.includes(Number(item.wg_id))
    return item
})

回答：

  const curr_data_list = [{
    warehouse_id: "1",
    wg_id: "111"
  }, {
    warehouse_id: "2",
    wg_id: "222"
  }, {
    warehouse_id: "3",
    wg_id: "333"
  }, {
    warehouse_id: "4",
    wg_id: "444"
  }]
  const wg_ids_obj = [
    {
      id: 222
    },
    {
      id: 444
    }
  ]
  const newData = curr_data_list.map(item => {
    const is_selector_val = wg_ids_obj.some(i => i.id === +item.wg_id)
    return {
      ...item,
      is_selector_val
    }
  })

回答：

curr_data_list.map(item=>({

...item,
is_selector_val:wg_ids_arr.map(wia=>wia.target).includes(Number(item.wg_id))

}))

如果wg_ids_arr是对象数组的话target就是你要取值判断的key

回答：

let curr_data_list = [{
    warehouse_id: "1",
    wg_id: "111",
},{
    warehouse_id: "2",
    wg_id: "222",
},{
    warehouse_id: "3",
    wg_id: "333",
},{
    warehouse_id: "4",
    wg_id: "444",
}]
let wg_ids_arr = [{id:"11"},{id:"111"},{id:"32"},{id:"444"},{id:"654"}]
const result = curr_data_list.filter((item)=>{
    item.is_selector_val = false //默认给每个curr_data_list添加一个is_selector_val为false值
    wg_ids_arr.filter((ele)=>{
        if(item.wg_id == ele.id){ //遍历过滤，给符合配合的添加is_selector_val为ture
            item.is_selector_val =  true
        }
    })
})
console.log(curr_data_list)
不知道是否符合你的要求
