先上图
在一个form里面实现两个文件的不同时上传,两个上传互不干涉.
之前只有一个file 和submit,即Select Excel File那一行;现在我加上了下面的Feedback File 一行file和submit.
结果导致只能Feedback这个submit能够上传文件,Select那一行的submit一上传就出错,说是The input file was not found.
然后我后台输出Select一行的file.getFileName()为空.这是为什么呢!
上代码
这是form体
- HTML code
<html:form action="uploadAction.do?method=upFile" enctype="multipart/form-data"> <c:choose> <c:when test="${zn == 'pilot'}"> <input type="radio" name="name" value="pilot" checked="checked" onclick="getZoneDate('pilot');"/> <font color="red">PRFQ1</font> </c:when> <c:otherwise> <input type="radio" name="name" value="pilot" onclick="getZoneDate('pilot');"/> <font color="red">PRFQ1</font> </c:otherwise> </c:choose> <c:choose> <c:when test="${zn == 'week'}"> <input type="radio" name="name" value="week" checked="checked" onclick="getZoneDate('week');"/> <font color="red">PRFQ2</font> </c:when> <c:otherwise> <input type="radio" name="name" value="week" onclick="getZoneDate('week');"/> <font color="red">PRFQ2</font> </c:otherwise> </c:choose> <br/> Select Excel File:<html:file property="theFile" /> <html:submit value="upload"/> <br/> FeedBack File:<html:file property="theFile" /> <html:submit value="upload" onclick="this.form.action='uploadAction.do?method=upFBFile'"/> </html:form>这是后台action过程
Select一行的submit
