[英]how to get value that is given in select tags from one jsp page to another jsp page
问题描述
Actually if i select an option like "company" and click on "submit" it will go to "view2.jsp" and using the option which i selected in "view1.jsp" i will display only that "company" data into either PDF,DOC,XLS,XLSX. 
实际上，如果我选择“公司”之类的选项并单击“提交”，它将转到“ view2.jsp”，并使用我在“ view1.jsp”中选择的选项，我只会将“公司”数据显示到任一PDF中，DOC，XLS，XLSX。 Here i am using jasper reports in order to display data into PDF or DOC or XLS or XLSX. 我在这里使用jasper报告，以便将数据显示为PDF或DOC或XLS或XLSX。 What i did was as follows 我所做的如下
view1.jsp view1.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">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<form method="POST" action="view2.jsp">
<select name="category">
<option value='company'>company</option>
<option value='institution'>institution</option>
<option value='hospital'>hospital</option>
<option value='Others'>Others</option>
</select>
<input type='submit' value="Given">
</form>
</body>
</html>
view2.jsp view2.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">
<html>
<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>
<%
String name;
name = request.getParameter("category");
%>
<form>
<select value="name" onchange="setAction(this.value)">
<option value=''> Make a selection </option>
<option value='PDF2.jsp'> PDF</option>
<option value='XLS2.jsp'> XLS </option>
<option value='DOC.jsp'> DOC </option>
<option value='XLSX2.jsp'> XLSX </option>
</select>
 
<input type='submit' value="Submit">
</form>
</body>
</html>
But the problem i am facing is that i am not getting the option value that i selected in view1.jsp to view2.jsp and i am not getting the option data into PDF and DOC and XLS and XLSX. 但是我面临的问题是我没有将我在view1.jsp中选择的选项值获取到view2.jsp，也没有将选项数据获取到PDF，DOC和XLS和XLSX中。

request.getParameter("category"); this is returning you the drop down value which you selected in view1 which you are storing in name . 这将返回您在view1中选择的下拉值，该值存储在name 。
You can simply display it on view2.jsp as You have chosen <%= name %> on page name(view1.jsp). 您只需在页面名称（view1.jsp）上You have chosen <%= name %>即可在view2.jsp上显示它。
