{"totalpages":"3","currpage":"1","totalrecords":"11","griddata":[{"SalesReasonID":"1","Name":"Price","ReasonType":"Other","ModifiedDate":"1998年6月1日"},{"SalesReasonID":"2","Name":"On Promotion","ReasonType":"Promotion","ModifiedDate":"1998年6月1日"},{"SalesReasonID":"3","Name":"Magazine

其对应的jsonReader为：jsonReader: {

root: "griddata",

total: "totalpages",

page: "currpage",

records: "totalrecords",

repeatitems: false

}

注：cell、id在repeatitems为true时可以用到，即每一个记录是由一对id和cell组合而成，即可以适用另一种json结构。援引文档中的例子：

repeatitems为true时：

jQuery("#gridid").jqGrid({

...

jsonReader : {

root:"invdata",

page: "currpage",

total: "totalpages",

records: "totalrecords"

},

...

});

json结构为：

{

"totalpages": "xxx",

"currpage": "yyy",

"totalrecords": "zzz",

"invdata" : [

{"id" :"1", "cell" :["cell11", "cell12", "cell13"]}, // cell中不需要各列的name，只要值就OK了，但是需要保持对应

{"id" :"2", "cell" :["cell21", "cell22", "cell23"]},

...

]

}

repeatitems为false时：

jQuery("#gridid").jqGrid({

...

jsonReader : {

root:"invdata",

page: "currpage",

total: "totalpages",

records: "totalrecords",

repeatitems:
false,

id: "0"

},

...

});

json结构为：

{

"totalpages" : "xxx",

"currpage" : "yyy",

"totalrecords" : "zzz",

"invdata" : [

{"invid" : "1","invdate":"cell11", "amount" :"cell12", "tax" :"cell13", "total" :"1234", "note" :"somenote"}, // 数据中需要各列的name，但是可以不按列的顺序

{"invid" : "2","invdate":"cell21", "amount" :"cell22", "tax" :"cell23", "total" :"2345", "note" :"some note"},

...

]

}
