内容图文
查了很多资料，有点乱
首先声明一下这里必须要用easyui1.3.1
不多说直接上代码：
首先打开jquery.easyui.min.js，查找_53b()
找到下面的代码
function
_53b(){
var _53c=opts.loader.call(_538,_53a,function(data){
setTimeout(function(){
$(_538).datagrid("loaded");
},0);
_4b1(_538,data);
setTimeout(function(){
_52b(_538);
},0);
}
替换成下面这段代码
function
_53b(){
var _53c=opts.loader.call(_538,_53a,function(data){
//add dynamic columnsif(data!=null && data.cols!=null){
var opts=$.data(_538, "datagrid").options;
var cols = $.data(_538, "datagrid").options.columns[0];
var colCount=cols.length;
if(colCount==0){
for (var i = 0; i < data.cols.length; i++) {
var col = {
field: data.cols[i].field,
title: data.cols[i].title,
width: data.cols[i].width
};
cols.push(col);
}
//UI if (colCount==0 && opts.columns) {
_461(_538);
}
}
}
setTimeout(function(){
$(_538).datagrid("loaded");
},0);
_4b1(_538,data);
setTimeout(function(){
_52b(_538);
},0);
}
然后开始写html

$(
function

$(
‘

).datagrid({
title:
‘

,
width:

height:
350

后代码如下：
using
System;
using
System.Collections.Generic;
using
System.Linq;
using
System.Web;
using
System.Web.Services;
using
Newtonsoft.Json;
using
Newtonsoft.Json.Linq;
using
System.Web.Script.Services;
namespace
MyWeb.Services {
///
<summary>
///
EmployeeService
///
</summary>
[WebService(Namespace = ")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// ASP.NET AJAX Web ?? [System.Web.Script.Services.ScriptService]
publicclass EmployeeService : System.Web.Services.WebService {
[WebMethod]
publicvoid GetCustomerList() {
//////
NorthwindEntities db=new NorthwindEntities();
//
int count = db.Customers.Count();
//
int page = Convert.ToInt32(Context.Request.Form["page"]);
int rows = Convert.ToInt32(Context.Request.Form["rows"]);
//
List<Customers> cusList = db.Customers.OrderBy(c => c.CustomerID).Skip((page - 1) * rows).Take(rows).ToList();
//JSON
JObject result = new JObject(
new JProperty("total", count),
new JProperty("rows", new JArray(
from c in cusList
selectnew JObject(
new JProperty("CustomerID", c.CustomerID),
new JProperty("Name", c.ContactName),
new JProperty("City",c.City),
new JProperty("Address",c.Address)
)
))
);
//??
List<EColumn> colList = new List<EColumn>() {
new EColumn{Field="CustomerID",Title="",Width=80},
new EColumn{Field="Name",Title="",Width=80},
new EColumn{Field="City",Title="",Width=80},
new EColumn{Field="Address",Title="",Width=120},
};
JArray cols = new JArray(
from c in colList
selectnew JObject(
new JProperty("field", c.Field),
new JProperty("title", c.Title),
new JProperty("width", c.Width),
new JProperty("sortable", c.Sortable),
new JProperty("checkbox", c.Checkbox)
)
);
result.Add(new JProperty("cols", cols));
Context.Response.ContentType = "application/json;utf-8";
Context.Response.Write(result.ToString());
}
}
}
补充一个类
using
System;
using
System.Collections.Generic;
using
System.Linq;
using
System.Web;
namespace
MyWeb {
[Serializable]
public
class
EColumn {
public
string Field { get; set; }
publicdouble Width { get; set; }
publicstring Title { get; set; }
publicbool Sortable { get; set; }
publicbool Checkbox { get; set; }
}
}
OK搞定
