后臺給我返回來一個判斷type_name分為車商和車型，車型取car_title,車商取title。請問怎么在花括號里判斷？這是我寫的，會報錯：{{item.type_name=='車商'？item.title:item.type_name=='車型'?item.car_title:'暫無數(shù)據(jù)'}}這是后臺返回的數(shù)據(jù)：{"id":3,"uid":1,"type_id":2,"relation_id":1,"create_time":"2018年04月2521:40","car_title":null,"car_content":null,"car_pic":null,"title":"超級管理員","type_name":"車商"}
