假設(shè)一個(gè)數(shù)組長這樣varqq=[{"group":100,"info":{"event":123},"main":true,},{"group":100,"info":{"event":323},"main":false,"sp":12},{"group":103,"info":{"event":123},"main":true,"sp":13,},{"group":103,"info":{"event":323},"main":false,"sp":10},{"group":103,"info":{"event":123},"main":false,"sp":1}];group是同數(shù)字表示是一組的，我想要把同一組的放在一起，還有一個(gè)特殊情況，sp===1的話，就把它放到前一個(gè)陣列的最后一個(gè)位置也就是最后輸出要這樣varqq=[[{"group":100,"info":{"event":123},"main":true,},{"group":100,"info":{"event":323},"main":false,"sp":12},{"group":103,"info":{"event":123},"main":false,"sp":1}],[{"group":103,"info":{"event":123},"main":true,"sp":13,},{"group":103,"info":{"event":323},"main":false,"sp":10}]];這樣具體該怎么實(shí)現(xiàn)?
