使用easyui的dategrid時，發現分頁欄顯示的數據總頁數總是不對，原來是
從後臺傳給前臺的字符串不能只是簡單的list轉成的json格式，還加上total和rows
具體格式如下，記錄一下
{
"total":239,
"rows":[
{"code":"001","name":"Name
1","addr":"Address 11","col4":"col4
data"},
{"code":"002","name":"Name
2","addr":"Address 13","col4":"col4
data"},
{"code":"003","name":"Name
3","addr":"Address 87","col4":"col4
data"},
{"code":"004","name":"Name
4","addr":"Address 63","col4":"col4
data"},
{"code":"005","name":"Name
5","addr":"Address 45","col4":"col4
data"},
{"code":"006","name":"Name
6","addr":"Address 16","col4":"col4
data"},
{"code":"007","name":"Name
7","addr":"Address 27","col4":"col4
data"},
{"code":"008","name":"Name
8","addr":"Address 81","col4":"col4
data"},
{"code":"009","name":"Name
9","addr":"Address 69","col4":"col4
data"},
{"code":"010","name":"Name
10","addr":"Address 78","col4":"col4
data"}
]
}
