JQuery简单的前台表单验证

判断下拉框是否有选择：

<script type="text/JavaScript">

function CheckForm(){

var AreaValue=$("#DDlAreaList").val();

if(AreaValue=="0")

{

top.Dialog.altert("请选择区域！");

return false;

}

return true;

}

</scirpt>

<asp:Button ID="btnSubmit" runat="server" Text="保存并返回" Width="80px" CssClass="blueButtonCss" OnClientClick="return CheckFrom();" OnClick="btnSubmit_Click" />  

关于IBatisNet中SQL语句的使用：

<!--<select id="searchDeclaration" resultMap="T_ED_DeclarationResult" parameterClass="T_ED_Declaration">
SELECT A.* FROM [T_ED_Declaration] A
<dynamic prepend="WHERE">
<isNotEmpty prepend=" and" property="Declaration_BatchNO">
A.Declaration_BatchNO like '%$Declaration_BatchNO$%'
</isNotEmpty>
<isNotEqual prepend=" and" property="Declaration_PortName" comparevalue="0">
A.Declaration_PortName like '%$Declaration_PortName$%'
</isNotEqual>
<isGreaterThan prepend=" and" property="StartTime" compareValue="1900-1-1">
<![CDATA[
A.StartTime<= #StartTime#
]]>
</isGreaterThan>
<isGreaterThan prepend=" and" property="EndTime" compareValue="1900-1-1">
<![CDATA[
A.EndTime<= #EndTime#
]]>
</isGreaterThan>
</dynamic>
</select>-->
