簡單定義checkbox

<html:multibox property="fruits" value="Strawberry"/>Strawberry<br />

<html:multibox property="fruits" value="Apple"/>Apple<br />

<html:multibox property="fruits" value="Orange"/>Orange<br />

<html:multibox property="fruits" value="Pear"/>Pear<br />

<html:multibox property="fruits" value="Mango"/>Mango<br />

<html:multibox property="fruits" value="Banana"/>Banana<br />

<html:multibox property="fruits" value="Pineapple"/>Pineapple<br />

用循環的方式創建checkbox

<logic:iterate name="colors" id="color">

       <html:multibox property="colors">

           <bean:write name="color" />

       </html:multibox>

       <bean:write name="color" /><br />

</logic:iterate>

<logic:iterate name="multiboxForm" property="colors" id="color">

    <bean:write name="color" />

</logic:iterate>

public ActionForward execute(

        ActionMapping mapping,

        ActionForm form,

        HttpServletRequest request,

        HttpServletResponse response)

        throws Exception {

        if (isCancelled(request)) {

            return mapping.findForward("home");

        }

        return mapping.findForward("success");

}
