没有源码的同学跳到第六讲下载源码再来。
我们需要漂亮的UI，不要系统自动生成的垃圾UI。我们在大数据面前，我们要减少页面的压力，不要在页面遍历List
我们选择Easyui的DataGrid最为本系统的表格展示效果
本节知识点：
- 根据DataGrid json格式在controller制作json格式给DataGrid用
我们的系统似乎越来越有趣了、
首先从前端入手，开打View下面的Shared创建一个视图模版
<!DOCTYPE html>
<html>
<head>
<title>Main</title>
<script src="@Url.Content("~/Scripts/jquery.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.easyui.min.js")" type="text/javascript"></script>
@Styles.Render("~/Content/css")
@Styles.Render("~/Content/themes/blue/css")
</head>
<body>
<div style="padding:5px 5px 0px 5px;">
@RenderBody()
</div>
</body>
</html>
_Index_Layout.cshtml
以后我们系统用到的index视图基本要引用这个模版
@using App.Admin;
@using App.Common;
@{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Index_Layout.cshtml";
}
<table id="List"></table>
<script type="text/javascript">
$(function () {
$('#List').datagrid({
url: '/SysSample/GetList',
$(window).width() - 10,
methord: 'post',
height: $(window).height() -35,
fitColumns: true,
sortName: 'Id',
sortOrder: 'desc',
idField: 'Id',
striped: true, //奇偶行是否区分
singleSelect: true,//单选模式
rownumbers: true,//行号
columns: [[
{ field: 'Id', title: 'ID', 80 },
{ field: 'Name', title: '名称', 120 },
{ field: 'Age', title: '年龄', 80, align: 'right' },
{ field: 'Bir', title: '生日', 80, align: 'right' },
{ field: 'Photo', title: '照片', 250 },
{ field: 'Note', title: '说明', 60, align: 'center' },
{ field: 'CreateTime', title: '创建时间', 60, align: 'center' }
]]
});
});
</script>
index.cshtml
在SysSampleController添加GetLists方法给视图的AJAX使用
[HttpPost]
public JsonResult GetList()
{
List<SysSampleModel> list = m_BLL.GetList("");
var json = new
{
total = list.Count,
rows = (from r in list
select new SysSampleModel()
{
Id = r.Id,
Name = r.Name,
Age = r.Age,
Bir = r.Bir,
Photo = r.Photo,
Note = r.Note,
CreateTime = r.CreateTime,
}).ToArray()
};
return Json(json, JsonRequestBehavior.AllowGet);
}
预览一下效果
有的童鞋可能有疑问了，问我怎么知道要返回这么json格式给datagrid。
其实有心的童鞋会发现下载的easyui包里面有个demo文件，我们打开datagrid样例的文件夹找到
{"total":28,"rows":[
{"productid":"FI-SW-01","productname":"Koi","unitcost":10.00,"status":"P","listprice":36.50,"attr1":"Large","itemid":"EST-1"},
{"productid":"K9-DL-01","productname":"Dalmation","unitcost":12.00,"status":"P","listprice":18.50,"attr1":"Spotted Adult Female","itemid":"EST-10"},
{"productid":"RP-SN-01","productname":"Rattlesnake","unitcost":12.00,"status":"P","listprice":38.50,"attr1":"Venomless","itemid":"EST-11"},

我是根据这个来的，你学会了吗？
此时有的童鞋又有疑问了你怎么知道你返回的对不对，假如你的谷歌或者火狐浏览器那你可以看到你返回的json类型
童鞋你懂了吗？慢慢拼出符合的格式
