view.jsp的

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"

<script type="text/javascript">

    function setAction(nPage){
        document.forms[0].action = nPage;

<body>
<form>
<% String Name=request.getParameter("category"); %>
<select  name="Name" onchange="setAction(this.value)">
<option value=''> Make a selection </option>
<option name="cat" value='PDF2.jsp'> PDF</option>
<option name="cat" value='XLS2.jsp'> XLS </option>

<option value='XLSX2.jsp'> XLSX </option>
</select>

<input type='submit' value="Submit">
</form>

</html>

现在我的问题是我需要得到＆＃34;公司＆＃34;从purchase.jsp到view.jsp的String Name并获取＆＃34; Name＆＃34;进入<select name="Name" onchange="setAction(this.value)">以便当我选择＆＃34; PDF.jsp＆＃34;然后点击提交，pdf仅包含＆＃34;公司＆＃34;的数据。没有别的。我在使用jasper报告将数据输入pdf。

尝试以下代码：

<% String Name=request.getParameter("category"); %>
<select  name="<%=Name%>" onchange="setAction(this.value)">
<option value=''> Make a selection </option>
<option name="cat" value='PDF2.jsp'> PDF</option>
<option name="cat" value='XLS2.jsp'> XLS </option>
<option value='DOC.jsp'> DOC </option>
<option value='XLSX2.jsp'> XLSX </option>
</select>
