我有一个包含图像的jsp页面,当我点击该图像时,它应该转到其他jsp页面。如何在struts2中执行此操作。在添加图像操作之前它工作正常。

如果您只是想要一个与锚相关联的图像,您可以按如下方式进行:
<s:url var='imageUrl' action='yourActionName'/>
<s:a href='%{#imageUrl}'><img src='<s:url value="images/yourimage.jpg"/>'/></s:a>
您会注意到我构建了一个命名URL,引用了Struts2锚标记的href属性中的命名URL,并使用内联URL引用了要显示的图像的正确的基于上下文的路径。 / p>
但是,对于您的问题,您</a>
中包含的第一个图片链接中似乎有一个迷路products.jsp
。
答案 1 :(得分:0)
首先,您在 <a href="<s:url action="cancel.action" />"><img src="image/1.png" class="tooltip" height="42" width="42" title="BP monitor" id="BP monitor" > </a>
<a href="<s:url action="hello.action"/>"><img src="image/2.jpg" height="42" width="42" class="tooltip" title="sethescope" id="sethescope"></a>
文件中定义操作并预测该操作类,我们可以使用这种方式调用操作。
<强> Products.jsp 强>
<action name="cancel"
class="com.test.CancelAction"
method="execute">
<result name="success">/Cancel.jsp</result>
</action>
<action name="hello"
class="com.test.ApproveAction"
method="execute">
<result name="success">/Approve.jsp</result>
</action>
和strtus.xml
XML
并定义我在<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
文件中定义的类,并返回Sucess消息并检查.it将确保正常工作。对不起,我已经拍了一些其他图片用于测试目的。谢谢,有任何疑问,请在这里询问。
将strtus.xml中的<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
更改为 var addressWithoutEmtySpacesMoreThanOne = Regex.Replace(address, @"\s+", " ");
var result = new Regex("[^a-zA-Zа-яА-Я0-9 -]").Replace(addressWithoutEmtySpaces, "");
customer.Address = result;
