Jquery easyui + MVC实现无限级部门小示例

使用jquery easyui和MVC实现无限级部门的treeview 升降级重命名新增等功能。

1、效果预览：

2、Department数据库设计：

Description暂时未用和Deep只是识别了一下深度为0的为root级部门（可以换用ParentId==null识别，Deep虽只是标示了root级别部门但在实现升降时候也做了相应的处理）。

CREATE TABLE [dbo].[Department](    Id int identity(1,1) NOT NULL,     Name nvarchar(50) NOT NULL,    [Description] nvarchar(400) NOT NULL,    ParentId int NULL,    Deep int NOT NULL default(0),)--主键ALTER TABLE [dbo].[Department]    ADD CONSTRAINT [PK_Department]    PRIMARY KEY (Id)--自引用外键ALTER TABLE [dbo].[Department]    ADD CONSTRAINT [FK_Department_ParentId]     FOREIGN KEY (ParentId)    REFERENCES [dbo].[Department] (Id)

3、数据访问使用的是NHibernate 使用codesmith生成，并加以改造。

默认生成的hbm和model使用起来不是很方便hbm增加一个one-to-many的Departments来获取当前Department下的子部门。

改造后的hbm文件内容如下：

<?xml version="1.0" encoding="utf-8" ?><hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" namespace="IMubiao.Data.DomainModels" assembly="IMubiao.Data">    <class name="IMubiao.Data.DomainModels.Department, IMubiao.Data" table="[dbo].[Department]" lazy="true">        <id name="Id" column="[Id]">             <generator class="native" />        </id>        <property name="Name" column="[Name]" />        <property name="Description" column="[Description]" />        <property name="Deep" column="[Deep]" />        <many-to-one name="DepartmentMember" column="[ParentId]" class="Department" />    <bag name="Departments" lazy="true" cascade="all-delete-orphan" inverse="true" >      <key column="[ParentId]"></key>      <one-to-many class="Department"></one-to-many>    </bag>        <bag name="Hrms" lazy="true" cascade="all-delete-orphan" inverse="true" >            <key column="[DepartmentId]"></key>            <one-to-many class="Hrm"></one-to-many>        </bag>    </class></hibernate-mapping>

对模板生成的model也要进行相应的修改（对应修改的hbm文件进行相应处理）

?
privateIList<Department> _dep = newList<Department>(); 
[JsonProperty]
publicvirtual IList<Department> Departments
{
get{ return _dep; } 
set
{
OnDepartmentsChanging();
_dep = value;
OnDepartmentsChanged();
}
}
partialvoid OnDepartmentsChanging();
partialvoid OnDepartmentsChanged();

涉及到的view index.aspx（显示效果就是开头的预览图效果）两个easyui-window 做部门降级和新增的容器代码：

?
<divclass="easyui-panel"title="部门管理"icon="icon-option"collapsible="true"minimizable="true"
maximizable="false"style="height: 500px; padding: 10px; background: #fafafa;">
<ulid="department_tree"style="height: 350px;">
</ul>
<divid="department_tree_menu"class="easyui-menu"style="width: 120px;">
<divonclick="dep_up()"iconcls="icon-up">
升级</div>
<divonclick="dep_down()"iconcls="icon-down">
降级</div>
<divclass="menu-sep">
</div>
<divonclick="dep_rename()"iconcls="icon-rename">
重命名</div>
<divclass="menu-sep">
</div>
<divonclick="department_add(0)"iconcls="icon-add">
新增子部门</div>
</div>
<divid="show_d_tree"class="easyui-window"closed="true"title="选择上级部门"iconcls="icon-list"
style="width: 200px; height: 300px; padding: 5px; background: #fafafa;">
<divclass="easyui-layout"fit="true">
<divregion="center"border="false"style="padding: 10px; background: #fff; border: 1px solid #ccc;">
<divid="load_tree">
</div>
</div>
</div>
</div>
<divid="department_add"class="easyui-window"closed="true"title="新增部门"iconcls="icon-add"
style="width: 300px; height: 200px; padding: 5px; background: #fafafa;">
<divclass="easyui-layout"fit="true">
<divregion="center"border="false"style="padding: 10px; background: #fff; border: 1px solid #ccc;">
<div>
<ul>
<listyle="list-style-type: none; height: 30px;">
<inputtype="hidden"id="parent_id"value=""/> 
<label>
上级部门:</label><labelid="parent_text"style="color: Green;">无</label></li>
<listyle="list-style-type: none; height: 30px;">
<labelfor="department_name">
部门名称:</label><inputtype="text"id="department_name"/> 
</li>
<listyle="list-style-type: none; height: 30px;"><ahref="javascript:department_create()"
class="easyui-linkbutton"icon="icon-save">保存</a></li>
</ul>
</div>
</div>
</div>
</div>
<divstyle="margin: 10px;">
<ahref="javascript:department_add()"class="easyui-linkbutton"icon="icon-add">新增部门</a>
<ahref="javascript:reload();"class="easyui-linkbutton"icon="icon-reload">重新加载</a>
</div>
</div>

部门降级用到了一个PreDown.aspx的PartialView 代码如下：

?
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<int>" %>
<ulid="pre_down">
</ul>
<listyle="list-style-type: none; margin-top: 5px;">
<labelfor="selected">
已选择:</label><labelid="selected"style="color: Green;">未选择</label></li>
<listyle="list-style-type: none;">
<inputtype="hidden"id="id_transfer"value="<%=Model %>" /> 
<inputtype="hidden"id="selected_id"/> 
<ahref="javascript:submit_down()"icon="icon-ok"class="easyui-linkbutton">确认降级</a></li>
<scripttype="text/javascript">
$(function () {
$('#pre_down').tree({
checkbox: false,
url: '<%=Url.Action("PreDownData","Department",new {id=Model}) %>?' + new Date().getTime(),
onClick: function (node) {
$('#selected').text(node.text);
$('#selected_id').val(node.id);
$(this).tree('toggle', node.target);
}
});
});
function submit_down() {
$.post('<%=Url.Action("Down","Department") %>', { id: $('#id_transfer').val(), pid: $('#selected_id').val() }, function () {
$('#show_d_tree').window('close');
$('#department_tree').tree('reload');
});
}
</script>

效果预览：

部门降级只能降至当前部门上级部门的子部门一下部门，也就是这个原因没有使用easyui tree的拖拽功能去做功能调整。

用到的几个js function：

?
<script type="text/javascript">
//初始化部门的tree
$(function() { 
$('#department_tree').tree({
animate:true,
url:'<%=Url.Action("DataList","Department") %>',
onClick:function (node) { 
$(this).tree('toggle', node.target); 
},
onDblClick:function (node) { 
$('#department_tree').tree('beginEdit', node.target); 
},
onAfterEdit:function (node) { 
$.post('<%=Url.Action("Edit","Department") %>', { id: node.id, name: node.text }); 
reload();
},
onContextMenu:function (e, node) { 
e.preventDefault();
$('#department_tree').tree('select', node.target); 
$('#department_tree_menu').menu('show', { 
left: e.pageX,
top: e.pageY
});
}
});
});
//刷新部门树
functionreload() { 
$('#department_tree').tree('reload');
}
//部门升级 
functiondep_up() { 
varnode = $('#department_tree').tree('getSelected');
$.post('<%=Url.Action("UP","Department") %>', { id: node.id },function () { 
$('#department_tree').tree('reload');
});
}
//部门降级 
functiondep_down() { 
varnode = $('#department_tree').tree('getSelected');
$('#load_tree').empty().load('<%=Url.Action("PreDown","Department") %>/' + node.id, function() { 
$('#show_d_tree').window('open');
});
}
//重命名 
functiondep_rename() { 
varnode = $('#department_tree').tree('getSelected');
$('#department_tree').tree('beginEdit', node.target); 
}
//新增部门 
functiondepartment_add(val) { 
if(val == undefined || val == null) {
$('#parent_id').val('');
$('#parent_text').text('无');
}
else{ 
varnode = $('#department_tree').tree('getSelected');
$('#parent_id').val(node.id);
$('#parent_text').text(node.text);
}
$('#department_name').val('');
$('#department_add').window('open');
}
//新增窗体里保存按钮的提交操作
functiondepartment_create() { 
varpid = $('#parent_id').val();
varname = $('#department_name').val();
name = encodeURIComponent(name);
$.post('<%=Url.Action("Create","Department") %>', { pid: pid, name: name }); 
reload();
$('#department_add').window('close');
}
</script>

DepartmentController Actions说明：

提供无限级tree数据的DataList 内容：

?
public string DataList(int? id)
{
varpreModel = db.Departments.Where(x => x.Deep == 0);
returnConvert(preModel).ToJson(); 
}
private List<Models.EUITreeModel> Convert(IQueryable<Department> model)
{
List<Models.EUITreeModel> result =new List<Models.EUITreeModel>(); 
foreach (varv inmodel) 
{
vartemp = newModels.EUITreeModel 
{
id = v.Id,
text = v.Name,
attributes = string.Empty,
iconCls = string.Empty,
};
if(v.Departments.Count > 0) 
{
temp.children = Convert(v.Departments.AsQueryable());
}
result.Add(temp);
}
returnresult; 
}

Convert方法做无限级部门的递归，绑定jquery easyui tree data。

对应　jquery easyui tree 的EUITreeModel 属性：

?
public class EUITreeModel 
{
publicint id { get;set; } 
publicstring text { get; set; }
publicstring iconCls { get; set; }
publicbool @checked{ get;set; } 
publicList<EUITreeModel> children { get;set; } 
publicstring attributes {get; set; } 
}

其他一些Action辅助做一些数据的更新和新增工作！
