手机输入的,可能描述不是很清晰。 假设我有源数据arr1 arr1 = [ {id: 1, label: '全部', billStatus: 'alldata', number: 0, pId: 0 }, {id: 2, label: '待提交', billStatus: 'free', number: 0, pId: 0, filter: 'free', operations: { free: '制作', close: '异常关闭', back: '退回需求', } }, {id: 3, label: '待会签', billStatus: 'commit', number: 0, pId: 0, filter: 'commit', operations: { commit: '会签', followup: '跟催' } }, {id: 4, label: '待审批', billStatus: 'approve', number: 0, pId: 0, filter: 'approve', operations: { approve: '审批', followup: '跟催' } }, {id: 5, label: '审批通过', billStatus: 'approvepass', number: 0, pId: 0, filter: 'approvepass', operations: { view: '查看', } }, {id: 6, label: '异常关闭', billStatus: 'close', pId: 0, }, {id: 7, label: '异常关闭审批中', billStatus: 'closeapprove', number: 0, pId: 6, filter: "closesign", operations: { followup: '跟催', view: '查看' } }, {id: 8, label: '异常关闭通过', billStatus: 'closeapprovepass', number: 0, pId: 6, filter: "closeapprovepass", operations: { view: '查看' } }, {id: 9, label: '退回需求', billStatus: 'back', number: 0, pId: 0, filter: "back", operations: { view: '查看' } } ] 当前有想取出的列表arr2 arr2 =[1,5,4,8] 也就是想在arr1对象中获取id为1,5,4,8的数据出来,应该怎么操作? 谢谢!
