我的json传值的格式是：
Array[{"id":"3","sendId":"1","destId":"0","content":"","mtime":"2014-09-27
21:49:39","name":"admin"},{"id":"4","sendId":"1","destId":"0","content":"ddddddddddddd","mtime":"2014-09-27
21:50:50","name":"admin"},{"id":"5","sendId":"1","destId":"0","content":"dddddddddddddddddddddddddddddddd","mtime":"2014-09-27
21:50:57","name":"admin"},{"id":"6","sendId":"1","destId":"0","content":"dwwwwwwwwwadadawdawda","mtime":"2014-09-27
21:51:04","name":"admin"},{"id":"7","sendId":"1","destId":"0","content":"wwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww","mtime":"2014-09-27

不知道是哪错了，请大神解答。。。
