比如有這樣一個object:var wordList=[ {"name":"熱烈","id":1},{"name":"萬分","id":2},{"name":"非常","id":3}, {"name":"歡迎","id":1},{"name":"感謝","id":2},{"name":"謝謝","id":3}, {"name":"您","id":2},{"name":"親","id":1},{"name":"大神","id"1} ]實現(xiàn)的功能是，枚舉一下所有的組合，比如n=3，就表示從中選擇3個，組成一組，所有的都列舉出來。但是id相同的不能列為一組，n=3{"name":"熱烈","id":1},{"name":"萬分","id":2},{"name":"非常","id":3},這是正確的{"name":"熱烈","id":1},{"name":"萬分","id":2}，{"name":"歡迎","id":1}這是錯誤的
