判断两个数组用的value是否相等

  this.list = [            {              user_type: 0,              user_id: 1003,              department_id: 1,              department_name: "公司xx",              mobile: "",              realname: "廖xx",              com_name: "任公司",              label: "廖建平",              value: 1003            },            {              user_type: 0,              user_id: 1004,              department_id: 1,              department_name: "公司领导",              mobile: "",              realname: "贺金生",              com_name: "任公司",              label: "贺xx",              value: 1004            },            {              user_type: 0,              user_id: 1005,              department_id: 1,              department_name: "公司领导",              mobile: "",              realname: "李欢",              com_name: "任公司",              label: "李xx",              value: 1005            }          ]  this.selectData = [            {              user_type: 0,              user_id: 1003,              department_id: 1,              department_name: "公司xx",              mobile: "",              realname: "廖xx",              com_name: "任公司",              label: "廖建平",              value: 1003            },            {              user_type: 0,              user_id: 1004,              department_id: 1,              department_name: "公司领导",              mobile: "",              realname: "贺金生",              com_name: "任公司",              label: "贺xx",              value: 1004            },                     ]

方法一

    let result = []            for (let i = 0; i < this.selectData.length; i++) {              let obj = this.selectData[i]              for (let j = 0; j < this.list.length; j++) {                let aj = this.list[j]                if (obj.value === aj.value) {                  result.push(aj)                  break                }              }            }            console.log("result", result)

方法二

   let arr3 = this.selectData.filter(obj =>              this.list.some(obj1 => obj.value == obj1.value)            )            console.info("arr3", arr3)            this.result = arr3

方法三

  let arr4 = []            let arr5            this.list.filter(obj => arr4.push(obj.value))            arr5 = this.selectData.filter(obj => arr4.indexOf(obj.value) !== -1)             this.result = arr5
