JQueryEasyUIdatagrid框架的基本使用_jquery

代码如下:

代码如下:

border="false">

Json格式数据一定要是双引号的，单引号无法显示数据哦；

数据格式如下：

代码如下:

{
"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"}
]
}

注意：表格Post或者get回来的请求中
page：3 代表page为key，然后选择的当前页码为3
rows：10 代表一页的大小为10
后台返回的数据的格式为：{total：''，rows：[{},{}]}
只要包含了总数tatol字段，rows是具体的行数
例如：
Asp.Net MVC 例子：
public JsonResult GetAllUserInfos()
{
int pageSize = 5;
int pageIndex = 1;
int.TryParse(this.Request["page"], out pageIndex);
int.TryParse(this.Request["rows"], out pageSize);

pageSize = pageSize <= 0 ? 5 : pageSize;
pageIndex = pageIndex <1 ? 1 : pageIndex;

var temp = db.UserInfo
.OrderBy(u=>u.Sort)
.Skip((pageIndex-1)*pageSize)
.Take(pageSize)
.ToList();
Hashtable ht = new Hashtable();
ht["total"] = db.UserInfo.Count();
ht["rows"] = temp;
return Json(ht);
}

Asp.Net WebForm 例子：
public void ProcessRequest(HttpContext context)
{
context.Response.COntentType= "text/plain";
var strWebName = context.Request["WebName"] ?? string.Empty;
var GoodsNo = context.Request["GoodsNo"] ?? string.Empty;
int categoryId = 0;

int pageIndex = 1;
int pageSize = 10;

int.TryParse(context.Request["rows"], out pageSize);
int.TryParse(context.Request["page"], out pageIndex);

decimal priceLeft = 0;
decimal priceRight = 1000000;
int goodsStatus = 0;
decimal.TryParse(context.Request["PriceLeft"], out priceLeft);
decimal.TryParse(context.Request["PriceRight"], out priceRight);
int.TryParse(context.Request["CategoryId"], out categoryId);
int.TryParse(context.Request["GoodsStatus"], out goodsStatus);
var goodsQueryParamter = new GoodsQueryParamter();


goodsQueryParamter.GoodsStatus = (Model.GoodsModel.GoodsStatusEnum)goodsStatus;

var ds = goodsService.GetGoodsList(goodsQueryParamter);
string json = string.Empty;

if (ds != null && ds.Tables.Count > 0)
{
System.Text.StringBuilder rowJson = new System.Text.StringBuilder();
int colLen = ds.Tables[0].Columns.Count;
DataColumnCollection col = ds.Tables[0].Columns;
foreach (DataRow row in ds.Tables[0].Rows)
{
System.Text.StringBuilder colJson = new System.Text.StringBuilder();
rowJson.Append("{");
for (int i = 0; i {
colJson.Append("\"" + col[i].ColumnName + "\":\"" + row[i].ToString() + "\",");
}
rowJson.Append(colJson.ToString().TrimEnd(','));
rowJson.Append("},");
}
json = "{\"total\":" + ds.Tables[0].Rows[0]["sumGoods"] + ",\"rows\":[" + rowJson.ToString().TrimEnd(',') + "]}";
}
context.Response.Write(json);
}

ASP.Net中有一个类也可以序列化Json格式数据；
