Question

Purchase.jsp Purchase.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<form method="post" action="view.jsp">
<select name="category">
<option name=''> Make a selection </option>
<option name='company'>company</option>
<option name='institution'>institution</option>
<option name='hospital'>hospital</option>
<option name='Others'>Others</option>
</select>


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

view.jsp view.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
<script type="text/javascript">

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

</script>
</head>
<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='DOC.jsp'> DOC </option>
<option value='XLSX2.jsp'> XLSX </option>
</select>
&nbsp;&nbsp

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

Now my question is i need to get "company" from purchase.jsp to String Name of view.jsp and get that "Name" into <select name="Name" onchange="setAction(this.value)"> so that when i select "PDF.jsp" and click submit that pdf consists of only the data of "company" and nothing else.Here i am using jasper reports to get data into pdf. 现在我的问题是我需要从purchase.jsp获取“ company”到view.jsp的String Name ，并将该“名称”获取到<select name="Name" onchange="setAction(this.value)">以便我选择“ PDF.jsp”，然后单击“提交”，pdf仅包含“公司”的数据，而没有其他内容。在这里，我使用jasper报告将数据转换为pdf。

Try the code below: 请尝试以下代码：

<% 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>
