struts2文件上传问题

发布于 2024-09-25 16:56:42 字数 517 浏览 3 评论 0原文

我想上传一个文件并通过显示字符串“成功/失败”来动态更新同一页面上其他 div 中的结果。当我将结果转发到新页面时，它工作正常。然而，对于下面提到的代码，它将 div id“two”更新为 [object HTMLDocument]。请告诉我解决它的方法。

<div id='two' style="border: 1px solid yellow;"><b>initial content</b></div>
<s:form id='theForm2' cssStyle="border: 1px solid green;" enctype="multipart/form-data" action='doUpload' method='post' theme="ajax">
<input type="file" name="upload" />
<s:submit value="GO2" theme="ajax" targets="two"/>
</s:form>

i want to upload a file and update result in other div on the same page dynamically just by showing a string "succeed/failed". It is working fine when i am forwarding result to a new page. However for below mentioned code it is updating div id "two" to [object HTMLDocument]. Please show me the way to solve it.

<div id='two' style="border: 1px solid yellow;"><b>initial content</b></div>
<s:form id='theForm2' cssStyle="border: 1px solid green;" enctype="multipart/form-data" action='doUpload' method='post' theme="ajax">
<input type="file" name="upload" />
<s:submit value="GO2" theme="ajax" targets="two"/>
</s:form>

您要上传什么类型的文件？

对于 struts.xml 文件中的操作，您需要有一个结果为 type="stream" 的操作

<action name="myAction" class="com.MyJavaFileAction">

            <result name="SUCCESS" type="stream">

            <param name="contentType">image/jpeg</param>
            <param name="inputName">fileStream</param>
            <param name="contentDisposition">attachment;filename="${filename}"</param>
            <param name="bufferSize">1024</param>

            </result>

What type of file are you trying to upload?

For your action in your struts.xml file you need to have an action that has a result that is of type="stream"

<action name="myAction" class="com.MyJavaFileAction">

            <result name="SUCCESS" type="stream">

            <param name="contentType">image/jpeg</param>
            <param name="inputName">fileStream</param>
            <param name="contentDisposition">attachment;filename="${filename}"</param>
            <param name="bufferSize">1024</param>

            </result>
