<s:set name=”technology”

         ‘.Net’: {’Linq’, ‘ ASP.NET 2.0′},

         }” />

<s:doubleselect label=”技术选择”

doubleName=”techdetail”

formName=”form1″

doubleList=”#technology[top]” />

<br/><br/>

Doubleselect演示数据演示2:

<s:set name=”mymap” value=”#request.map”/>

<s:doubleselect list=”#request.map.keySet()”

                doubleName=”mymap1″

                name=”doubleselect2″

                formName=”form1″

                doubleList=”#request.map[top]”

                label=”Map Test” />



<s:submit/>

</s:form>

    <tr>

        <td><s:property/></td>

    </tr>

</s:iterator>

</s:form>

</html>

3、struts.xml配置文件实例

<action name=”doubleSelectTest” method=”doubleSelectTest” class=”com.mobilesoft.esales.webapp.action.DoubleListAction”>

    <result name=”success”>test/doubleselect.jsp</result>

</action>

<action name=”doubleSelectPost” method=”doubleSelectPost” class=”com.mobilesoft.esales.webapp.action.DoubleListAction”>

    <result name=”success”>test/doubleselectpost.jsp</result>

</action>

4、STRUTS2级联下拉框间的换行<br >问题

在缺省时候,两个级联下拉框间是可以换行的,Struts2使用Freemarker来做模板,通过修改模板来定制标签缺省的树形。参考“Struts2中Datetimepicker控件的中文问题”中的方法,也即:

  • 修改struts.mxl,增加如下内容。

<constant name=”struts.serve.static” value=”false” />

<constant name=”struts.ui.templateDir” value=”struts” />

注意在struts2-core-2.0.11.jar/org/apache/struts2/default.properties中有几个与Freemarker对应的配置参数:

struts.ui.theme=xhtml
struts.ui.templateDir=template
#sets the default template type. Either ftl, vm, or jsp
struts.ui.templateSuffix=ftl

  • 覆盖缺省的静态文件

在resource目录(与WEB-INF同级或WEB-INF下)创建struts目录,并:

解压struts2-core-2.0.11.jar:/org/apache/struts2/static/ to /struts/

解压struts2-core-2.0.11.jar:/template/simple/ to /struts/simple/

解压struts2-core-2.0.11.jar:/template/xhtml/ to /struts/xhtml/

解压struts2-core-2.0.11.jar:/template/css_xhtml/ to /struts/css_xhtml/

解压struts2-core-2.0.11.jar:/template/ajax/ to /struts/ajax/

解压struts2-core-2.0.11.jar:/template/archive/ to /struts/archive

最后的目录结构如下:

struts/
- ajax/
- archive/
- css_xhtml/
- dojo/
- nls/
- src/
- animation/
- …
- xml/
- struts/
- widget/
- widgets/
- niftycorners/
- simple/
- xhtml/

  • 修改doubleselect的模板doubleselect.ftl

修改struts/simple/doubleselect.ftl去除其中的<br />
