20140604更新，发现了两种写法，第二种写法更佳
第一种：
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(){
$(_538).datagrid("loaded");
},0);
_4b1(_538,data);
setTimeout(function(){
_52b(_538);
},0);
}
替换成下面这段代码
function _53b(){
var _53c=opts.loader.call(_538,_53a,function(data){
//add dynamic columns
if(data!=null && data.cols!=null){
var opts=$.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
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="DynamicDataTable.aspx.cs" Inherits="MyWeb.DynamicDataTable" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "
<html xmlns="
<head runat="server">
<title></title>
<link href="js/easyui/themes/default/easyui.css" rel="stylesheet" type="text/css" />
<link href="js/easyui/themes/icon.css" rel="stylesheet" type="text/css" />
<script src="js/jquery-1.8.0.min.js" type="text/javascript"></script>
<script src="js/easyui/jquery.easyui.min.js" type="text/javascript"></script> <script src="js/jquery.json/jquery.json-2.2.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
$('#tbEmployee').datagrid({
title: 'Customer Infos',
width: 700,
height: 350,
nowrap: true,
pagination: true,
rownumbers: true,
url: 'Services/EmployeeService.asmx/GetCustomerList',
columns: [[]]
});
});
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<table id="tbEmployee">
</table>
</div>
</form>
</body>
</html>
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]
public class EmployeeService : System.Web.Services.WebService { [WebMethod]
public void 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 - ) * rows).Take(rows).ToList();
//JSON
JObject result = new JObject(
new JProperty("total", count),
new JProperty("rows", new JArray(
from c in cusList
select new 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=},
new EColumn{Field="Name",Title="",Width=},
new EColumn{Field="City",Title="",Width=},
new EColumn{Field="Address",Title="",Width=},
};
JArray cols = new JArray(
from c in colList
select new 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; }
public double Width { get; set; }
public string Title { get; set; }
public bool Sortable { get; set; }
public bool Checkbox { get; set; }
}
}
OK搞定

第二种：
这种方法是从一个国外网站上发现的的，膜拜大神！
这里只上代码，你会easyuigrid应该就能看懂，大体思路就是，后代获得列的集合后在动态绑定grid，实现的时间有点长，所以就不一点一点介绍了。
function loadData(scmc, scdx, xz, xx, nj, bj,lie) {
var tj = "";
if (scmc != "") {
tj += "&scmc=" + scmc;
}
if (scdx != "") {
tj += "&scdx=" + scdx;
}
if (xz != "") {
tj += "&xz=" + xz;
}
if (xx != "") {
tj += "&xx=" + xx;
}
if (nj != "") {
tj += "&nj=" + nj;
}
if (bj != "") {
bj += "&bj=" + bj;
}
//这里是重点
var colStruct = [];
var colItems = [];
colStruct.pop();
$.getJSON('/ceshi/ceshi1.ashx?op=anssit' + tj, { page: 1, rows: 10, order: 'asc', sort: 'xh', lie: lie }, function(data) {
if (data == null) {
alert("没有信息");
return;
}
var obj = eval(data.cols);//获得列的集合json
for (var i = 0; i < obj.length; i++) {
var value = obj[i];
var menuItem = {
field: value.field,
title: value.title,
align: value.align,
width: value.width,
sortable: value.sortable
};
colItems.push(menuItem);
}
colStruct.push(colItems);//处理成和easyui原版一样的格式
$('#List').datagrid({
columns: colStruct,//直接绑定即可
url: '/ceshi/ceshi.ashx?op=anssit' + tj,
width: 1000,
height: 330,
methord: 'post',
rownumbers: true,
sortName: 'xh',
sortOrder: 'asc',
idField: 'xh',
pageSize: 10,
pageList: [10, 20, 30, 40, 50],
pagination: true,
striped: true, //奇偶行是否区分
singleSelect: true
});
});
}
简单吧。
