求助_(:3⌒?)_現(xiàn)在后臺返回的數(shù)據(jù)是這樣的：selected=['FREQUENT_PURCHASE','HIGH_CONSUME','NO_COMMUNICATE','DRIVE_RECORDER','SMART_LOCK','CHILD_MACHINE','FACE_RECS'];但是我想要的是selectd={userTag:['FREQUENT_PURCHASE','HIGH_CONSUME'],communicationIntention：'NO_COMMUNICATE',products:['DRIVE_RECORDER','SMART_LOCK','CHILD_MACHINE'],cloudServices:['FACE_RECS'],}怎么根據(jù)下面的數(shù)據(jù)去重組？？data={"CLOUD_SERVICE":[{"code":"CLOUD_STORE","msg":"云存儲"},{"code":"FACE_RECS","msg":"人臉識別"},{"code":"WARN_CALL","msg":"電話報警"},{"code":"HUMAN_CHECK","msg":"人形檢測"},{"code":"SERVICE_NEARLY_EXP","msg":"服務快到期"}],"HAVE_PRODUCT":[{"code":"CAMERA","msg":"攝像機"},{"code":"SMART_LOCK","msg":"xxxx"},{"code":"CAT_EYE","msg":"xxxxx"},{"code":"SUIT","msg":"套裝"},{"code":"SMART_CURTAIN","msg":"xxxx"},{"code":"HW_VIDEO_RECORDER","msg":"硬盤錄像機"},{"code":"SENSE_WARN","msg":"傳感報警"},{"code":"CHILD_MACHINE","msg":"兒童機器人"},{"code":"DRIVE_RECORDER","msg":"行車記錄儀"},{"code":"SPORT_CAMERA","msg":"運動相機"},{"code":"NETWORK","msg":"網絡通訊"},{"code":"CAR_GOODS","msg":"汽車用品"},{"code":"PARTS","msg":"配件"},{"code":"SERVICE_PRODUCT","msg":"服務產品"},{"code":"SAAS_APP","msg":"SaaS應用"},{"code":"SMART_STORE","msg":"智能存儲"}],"USER_TAGS":[{"code":"FREQUENT_PURCHASE","msg":"購買頻繁"},{"code":"SMART_HOME_USER","msg":"xx家居用戶"},{"code":"MONITOR_USER","msg":"xx專業(yè)戶"},{"code":"NO_DEVICE","msg":"無設備用戶"},{"code":"INSTABLE_DEVICE","msg":"設備不穩(wěn)定"},{"code":"HIGH_ACTIVITY","msg":"活躍度高"},{"code":"HIGH_CONSUME","msg":"高消費能力"},{"code":"HOME_USER","msg":"家庭用戶"},{"code":"ENTERPRISE_USER","msg":"企業(yè)用戶"}],"COMMUNICATE_INTENTION":[{"code":"HAVE_INTENTION","msg":"有意向"},{"code":"NO_COMMUNICATE","msg":"沒有溝通過"},{"code":"NON_INTENTION","msg":"無意向"},{"code":"GET_DEAL","msg":"達成購買"}]}

像FREQUENT_PURCHASE這樣的串，首先你要獲取到它是data中的哪一類?？梢员闅v一遍data生成一個映射表typeMap：{CLOUD_STORE:'CLOUD_SERVICE',FACE_RECS:'CLOUD_SERVICE',CAMERA:'HAVE_PRODUCT',//...}你想要的selected，可以先初始化：lettargetSelected={userTag:[],communicationIntention:[],//...}這里有個小問題是targetSelected與data中的鍵不一致，但是一一對應，所以你要么寫個函數(shù)，要么寫個映射表,可以根據(jù)data中的key得到targetSelected中的key：functiongetKey(src){if(src=='CLOUD_SERVICE')return'cloudServices'//...}這樣，對于后端返回的數(shù)組selected中的每一項，分發(fā)到targetSelected即可。selected.forEach(type=>{letkey=typeMap[type]targetSelected[getKey(src)].push(type)})其實很簡單，但最好的方式后端直接返回規(guī)范的數(shù)據(jù)，如果實在不行再用上面的辦法。
