Struts标签<html:cancel/>取消按钮处理事件
<html:cancel/>标签默认情况下点击,是会报错的。
?
要想使用此按钮可以在 struts-config.xml 中的action 增加如下相应属性:
?
<set-property property="cancellable" value="true" />
?
详细位置如下所示:
?
<action attribute="helloForm" input="/form/hello.jsp" name="helloForm" path="/hello" scope="request" type="com.zwn.struts.action.HelloAction"> <set-property property="cancellable" value="true"/> <forward name="success" path="/form/helloSuccess.jsp" /> <forward name="fail" path="/form/helloFail.jsp" redirect="true"/>?</action>??
?
再在对应action里面增加对cancel按钮的处理方法:
?
?public ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response) { if (isCancelled(request)) { // 取消按钮处理return mapping.findForward("fail");}HelloForm helloForm = (HelloForm) form;return mapping.findForward("success");}??
