Determine whether the value used by two arrays is equal

This.list = [{user_type: 0, user_id: 1003, department_id: 1, department_name: "Company xx", mobile: "", realname: "Liao xx", com_name: "Ren Company", label: "Liao Jianping" Value: 1003}, {user_type: 0, user_id: 1004, department_id: 1, department_name: "Company leadership", mobile: "", realname: "he Jinsheng", com_name: "Ren Company" Label: "he xx", value: 1004}, {user_type: 0, user_id: 1005, department_id: 1, department_name: "Company leaders", mobile: "", realname: "Li Huan" Com_name: "Ren Company", label: "Li xx", value: 1005}] this.selectData = [{user_type: 0, user_id: 1003, department_id: 1, department_name: "Company xx" Mobile: ", realname:" Liao xx ", com_name:" Ren Company ", label:" Liao Jianping ", value: 1003}, {user_type: 0, user_id: 1004, department_id: 1 Department_name: "Company leaders", mobile: ", realname:" he Jinsheng ", com_name:" Ren Company ", label:" he xx ", value: 1004},]

Method one

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

Method three

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
