Purchase.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">

<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>

现在我的问题是，我需要将"company"从purchase.jsp获取到view.jsp的String Name中，并将"Name"获取到<select name="Name" onchange="setAction(this.value)">中，这样当我选择"PDF.jsp"并单击提交时，PDF只包含"公司"的数据，而不包含其他数据。在这里，我使用jasper报告将数据转换为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>
