恢复
1,EasyUI的使用本来要求两个小时完成,我用了一天,路漫漫啊!
下面来看下今天的收获吧!
主要是对EasyUI的增删改查
(1)首先是调用文件
<link href="~/Content/easyUI/icon.css" rel="stylesheet" /> <link href="~/Content/easyUI/default/easyui.css" rel="stylesheet" /> <script src="~/Scripts/jquery-1.7.1.min.js"></script> <script src="~/Scripts/jquery.easyui.min.js"></script> <script src="~/Scripts/easyui-lang-zh_CN.js"></script> <script src="~/Scripts/jquery.unobtrusive-ajax.min.js"></script>
(2)然后是添加主页
<div> <table id="roleList"></table> </div>
使用Jquery加载EasyUI的数据
function ShowAgain(Param) { $("#roleList").datagrid({ url: ‘@Url.Action("GetPageList","EasyUI2")‘, title: ‘角色列表‘, width: 700, height: 400, fitColumns: true, idField: ‘UserId‘, loadMsg: ‘正在加载角色的信息...‘, pagination: true, singleSelect: false, pageSize: 10, pageNumber: 1, pageList: [10, 20, 30], queryParams: Param, columns: [[ { field: ‘ck‘, checkbox: true, align: ‘left‘, width: 50 }, { field: ‘UserId‘, title: ‘编号‘, width: 80 }, { field: ‘UserName‘, title: ‘用户名‘, width: 120 }, { field: ‘UserAge‘, title: ‘年龄‘, width: 120 }, { field: ‘UserGender‘, title: ‘性别‘, width: 120 } ]], toolbar: [{ id: ‘toolbarAdd‘, text: ‘添加‘, iconCls: ‘icon-add‘, handler: AddShow }, { id: ‘toolbarEdit‘, text: ‘修改‘, iconCls: ‘icon-edit‘, handler: EditShow }, { id: ‘toolbarEdit‘, text: ‘删除‘, iconCls: ‘icon-remove‘, handler: DeleteShow }] });
编写服务端的程序:
public ActionResult GetPageList(int rows,int page) { string Name=Request["Name"]; int id1 = string.IsNullOrEmpty(Request["Id"]) ? 0 : Int32.Parse(Request["Id"]); int total; var result = bll.GetPageList<int>(u=>(true)&& (string.IsNullOrEmpty(Name) ? true:u.UserName.Contains(Name)) && (id1==0 ? true : u.UserId == id1) ,u=>u.UserId,rows,page,out total); return Json(new {total,rows=result},JsonRequestBehavior.AllowGet); }
注意:
GetPageList(int rows,int page);EasyUI的需要几个参数,total, 其返回的数据是要求这样的格式{total:‘‘,rows:[{},{}]}
所以要这样写return Json(new {total,rows=result},JsonRequestBehavior.AllowGet);
其发起的请求是要以上面的格式接受请求。
Id,和后面的u=>(true)&&
(string.IsNullOrEmpty(Name) ? true:u.UserName.Contains(Name))
&&
(id1==0 ? true : u.UserId == id1)是用来查询用的。后面会介绍。
二,增
(1)书写html语句
<div id="AddList"> @using (Ajax.BeginForm("Add", "EasyUI2", new AjaxOptions() { OnSuccess="AddAfter" })) { <table border="1"> <tr> <td>姓名:</td> <td>@Html.TextBoxFor(r => r.UserName)</td> </tr> <tr> <td>性别:</td> <td>@Html.TextBoxFor(r=>r.UserGender)</td> </tr> <tr> <td>年龄:</td> <td>@Html.TextBoxFor(r => r.UserAge)</td> </tr> </table> } </div>
JQuery在一开始是要先隐藏数据。
$("#AddList").hide();
当点击时变成显示,并调用函数
function AddShow() { $("#AddList").show(); $("#AddList").dialog({ title: "添加用户", collapsible: true, minimizable: true, maximizable: true, resizable: true, buttons: [{ text: "添加", iconCls: "icon-add", handler: function () { $("#AddList form").submit(); } }, { text: "取消", iconCls: "icon-cancel", handler: function () { $("#AddList").dialog("close"); } }] }); }
(2)书写服务器端程序
public ActionResult Add(UserInfo model) { bool boo= bll.Add(model); return Content(boo.ToString()); }
(3)添加完成是更新
function AddAfter(msg) { if (msg == "True") { $(‘#roleList‘).datagrid(‘reload‘); $("#AddList").dialog("close"); } else { $("#AddList").dialog("close"); alert("添加失败!"); } }
三,删除
(1)编写Jquery
function DeleteShow() { var items = ‘‘; var id = ‘‘; items = $(‘#roleList‘).datagrid(‘getSelections‘); $.each(items, function (i, item) { id += item[‘UserId‘] + ‘,‘; }); $.messager.confirm(‘提示‘, ‘确定要删除吗?‘, function(msg) { id = id.substring(0, id.length - 1); $.post("EasyUI2/Delete?a="+Date().toString(), { idList: id}, function (msg) { if (msg == "True") { location.reload(); id = ‘‘; } else { alert("删除失败!"); } }) }) }
(1)首先调用getSelections方法获取所有的选中项
(2)根据获取的数据组合成数组并发送到服务器
(3)编写服务器代码
public ActionResult Delete(string idList) { bool boo=false; //idList List<int> list = new List<int>(); string[] ids = idList.Split(‘,‘); foreach (var id in ids) { list.Add(int.Parse(id)); } boo = bll.DelByIds(list.ToArray()); return Content(boo.ToString()); }
服务器的底层是用OA写的。DelByIds是这么写的
public bool DelByIds(int[] id) { int a = 0; for (int i = 0; i < id.Length; i++) { bool boo= DelById(id[i]); if (boo) a++; } if (a != id.Length) return false ; return true; }
四,改
html
<!--修改--> <div id="Edit"> <iframe src="#"></iframe> </div>
jquery
注意:一开始时也要隐藏,点击时显示
function EditShow() { $("#Edit").show(); var items = $(‘#roleList‘).datagrid(‘getSelections‘);//获取选择的项目,当大于1时提示用户 if (items.length != 1) { $.messager.alert(‘警告‘, "请选择一条要修改的记录"); return; } var id = items[0]["UserId"]; //修改src属性,指向修改页面 $(‘#Edit iframe‘).attr("src", ‘@Url.Action("Edit","EasyUI2")?id1=‘ + id); $("#Edit").dialog({ title: "修改用户", collapsible: true, minimizable: true, maximizable: true, resizable: true, buttons: [{ text: "修改", iconCls: "icon-edit", handler: function () { $(‘#Edit iframe‘)[0].contentWindow.EditSubmit(); } }, { text: "取消", iconCls: "icon-cancel", handler: function () { $("#Edit").dialog("close"); } }] }); }
这段程序的关键是前面的调用获取选择的项目,
还有就是后面的调用点击修改时 $(‘#Edit iframe‘)[0].contentWindow.EditSubmit();调用Edit页面中的Jquery函数EditSubmit();
(2)Edit页面
@model Model.UserInfo @{ ViewBag.Title = "Edit"; } <script src="~/Scripts/jquery-1.7.1.min.js"></script> <script src="~/Scripts/jquery.easyui.min.js"></script> <script src="~/Scripts/jquery.unobtrusive-ajax.js"></script> <link href="~/Content/easyUI/default/tabs.css" rel="stylesheet" /> <link href="~/Content/easyUI/default/easyui.css" rel="stylesheet" /> <link href="~/Content/easyUI/icon.css" rel="stylesheet" /> <script> function EditSubmit() { $(‘form‘).submit(); } function EditAfter(msg) { window.parent.EditAfter(msg); } </script> <h2>Edit</h2> @using (Ajax.BeginForm("Edit", "EasyUI2", new AjaxOptions() { OnSuccess = "EditAfter" })) { <table border="1"> <tr> <td>编号:</td> <td>@Html.TextBoxFor(u => u.UserId)</td> </tr> <tr> <td>姓名:</td> <td >@Html.TextBoxFor(u=>u.UserName)</td> </tr> <tr> <td>性别:</td> <td>@Html.TextBoxFor(u => u.UserGender)</td> </tr> <tr> <td>年龄:</td> <td>@Html.TextBoxFor(u => u.UserAge)</td> </tr> </table> }
(3)服务器代码
public ActionResult Edit() { int id= String.IsNullOrEmpty(Request["id1"])? 0:Int32.Parse(Request["id1"]); var result = bll.GetById(id); return View(result); } [HttpPost] public ActionResult Edit(UserInfo model) { bool boo = false; if (model != null) { boo = bll.Edit(model); } return Content(boo.ToString()); }
第一个Edit是一开始点击修改时加载数据。
第二个是当数据修改完成时,提交修改数据。
五,查
(1)html
<!--搜索--> <div id="Select"> <table border="1"> <tr> <td>用户名:</td><td><input id="Name" type="text" /></td> <td>编号:</td><td><input id="Id" type="text" /></td> <td><input type="button" onclick="Select()" value="搜索" /></td> </tr> </table> </div>
使用最简单的table方式加载数据。
(2)Jquery
获取数据并传入”一“(最上面的程序),的函数中
function Select() { //获取查询数据 var Name1 = $("#Name").val(); var Id1 = $("#Id").val(); //向服务器请求 ShowAgain({ ‘Id‘: Id1, ‘Name‘: Name1 }); }
服务器:
public ActionResult GetPageList(int rows,int page) { string Name=Request["Name"]; int id1 = string.IsNullOrEmpty(Request["Id"]) ? 0 : Int32.Parse(Request["Id"]); int total; var result = bll.GetPageList<int>(u=>(true)&& (string.IsNullOrEmpty(Name) ? true:u.UserName.Contains(Name)) && (id1==0 ? true : u.UserId == id1) ,u=>u.UserId,rows,page,out total); return Json(new {total,rows=result},JsonRequestBehavior.AllowGet); }
获取数据并根据数据查询
(4)完成之后
function SelectAfter() { $(‘#roleList‘).datagrid(‘reload‘); }
完成的属于你自己的EasyUI
