遗留：修改分区

（遗留处理）修改分区：

SubareaAction（新增以下代码）：

	/**
	 * 修改分区信息
	 * @return
	 */
	public String edit(){
		//调用service#edit(subarea)
		subareaService.edit(model);
		
		return LIST;
	}

SubareaService（新增以下代码）：

	/**
	 * 修改分区数据
	 * @param model
	 */
	void edit(Subarea subarea);

SubareaServiceImpl（新增以下代码）：

	@Override
	public void edit(Subarea subarea) {
		//从数据库中按ID查询出subara
		Subarea _subarea = subareaDao.findById(subarea.getId());
		//将subarea中值赋给查询出的subarea
		_subarea.setAddresskey(subarea.getAddresskey());
		_subarea.setStartnum(subarea.getStartnum());
		_subarea.setEndnum(subarea.getEndnum());
		_subarea.setSingle(subarea.getSingle());
		_subarea.setRegion(subarea.getRegion());
		//根据region_id查询出region对象获取数据
		Region _region = regionDao.findById(subarea.getRegion().getId());
		//生成position字段，并赋给_subarea
		getPositon(_subarea, _region);
		//保存查询并修改后的_subarea
		subareaDao.update(_subarea);
	}

页面新增（分为html、js）：

html代码：

	<!-- 修改分区 -->
	<div class="easyui-window" title="分区添加" id="editSubareaWindow" collapsible="false" minimizable="false" maximizable="false" style="top:20px;left:200px">
		<div style="height:31px;overflow:hidden;" split="false" border="false" >
			<div class="datagrid-toolbar">
				<a id="edit" icon="icon-edit" href="#" class="easyui-linkbutton" plain="true" >修改</a>
			</div>
		</div>
		
		<div style="overflow:auto;padding:5px;" border="false">
			
			<form id="editSubareaForm" action="SubareaAction_edit.action" method="post">
				<input type="hidden" name="id"/>
				<table class="table-edit" width="80%" align="center">
					<tr class="title">
						<td colspan="2">分区信息</td>
					</tr>
					<tr>
						<td>选择区域</td>
						<td>
							<input id="editRegion" class="easyui-combobox" name="region.id"
    							data-options="valueField:'id',textField:'name',url:'RegionAction_ajaxList.action',mode:'remote'" />  
						</td>
					</tr>
					<tr>
						<td>关键字</td>

					</tr>
					<tr>
						<td>起始号</td>

					</tr>
					<tr>
						<td>终止号</td>
						<td><input type="text" name="endnum" class="easyui-validatebox" required="true"/></td>
					</tr>
					<tr>
						<td>单双号</td>
						<td>
							<select class="easyui-combobox" data-options="panelHeight:100" name="single" style="width:150px;">  
							    <option value="0">单双号</option>  
							    <option value="1">单号</option>  
							    <option value="2">双号</option>  
							</select> 
						</td>
					</tr>
					
				</table>
			</form>
		</div>
	</div>

js：

		$("#edit").click(function(){    //这段代码添加在$(function(){  })中
			$("#editSubareaForm").submit();
		});

	//双击加载数据到修改分区窗口
	function doDblClickRow(rowIndex, rowData){
		$("#editSubareaWindow").window('open');
		$("#editSubareaWindow").form('load',rowData);
		//console.info(rowData.region.name);
		//设置其value和text的值
		$("#editRegion").combobox('setValue', rowData.region.id);
		$("#editRegion").combobox('setText', rowData.region.name);
	}
