TA貢獻(xiàn)1796條經(jīng)驗(yàn) 獲得超4個(gè)贊

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(gè)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(gè)小問題是targetSelected與data中的鍵不一致，但是一一對(duì)應(yīng)，所以你要么寫個(gè)函數(shù)，要么寫個(gè)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(duì)于后端返回的數(shù)組selected中的每一項(xiàng)，分發(fā)到targetSelected即可。selected.forEach(type=>{letkey=typeMap[type]targetSelected[getKey(src)].push(type)})其實(shí)很簡(jiǎn)單，但最好的方式后端直接返回規(guī)范的數(shù)據(jù)，如果實(shí)在不行再用上面的辦法。
