如何將全局變量分配給 javascript map 的結果

Question

I have a mock data object, I created a 2 global JS arrays and assigning them to inside map, and printing, but the object doesn't prints comes as undefined.

以下是我嘗試過的

 var mock = { "collection_data_status_list": [{ "input_status_list": [{ "device_id": "r0", "sensor_data": { "snmp_yang_sensor": { "path": "IF-MIB:IF-MIB\/ifTable\/ifEntry0" } }, "collection_status": { "state": "ACTIVE_STATE", "error": {}, "reported_time": "1569948062" } }, { "device_id": "r0", "sensor_data": { "snmp_yang_sensor": { "path": "IF-MIB:IF-MIB\/ifTable\/ifEntry1" } }, "collection_status": { "state": "ACTIVE_STATE", "error": {}, "reported_time": "1569948062" } }, { "device_id": "r0", "sensor_data": { "snmp_yang_sensor": { "path": "IF-MIB:IF-MIB\/ifTable\/ifEntry2" } }, "collection_status": { "state": "ACTIVE_STATE", "error": {}, "reported_time": "1569948062" } }, { "device_id": "r0", "sensor_data": { "snmp_yang_sensor": { "path": "IF-MIB:IF-MIB\/ifTable\/ifEntry3" } }, "collection_status": { "state": "ACTIVE_STATE", "error": {}, "reported_time": "1569948062" } }, { "device_id": "r0", "sensor_data": { "snmp_yang_sensor": { "path": "IF-MIB:IF-MIB\/ifTable\/ifEntry4" } }, "collection_status": { "state": "ACTIVE_STATE", "error": {}, "reported_time": "1569948062" } }], "output_status_list": [{ "destination_id": "d0", "destination_context_id": "t1", "device_id": "r0", "sensor_data": { "snmp_yang_sensor": { "path": "IF-MIB:IF-MIB\/ifTable\/ifEntry0" } }, "collection_status": { "state": "ACTIVE_STATE", "error": {}, "reported_time": "1569948062" } }] }, {}], "query_options": { "page_token": "1", "page_size": 100 }, "result": { "request_result": "ACCEPTED", "error": {} } }; var input_list = []; var output_list = []; var newObj = {}; var new1 = mock.collection_data_status_list; debugger; var finalOutput = new1.map(function(item) { var input_list = []; var output_list = []; var newObj = {}; newObj = { input_list: item.input_status_list, output_list: item.output_status_list }; return newObj; }); console.log(newObj);
