我有两个单选按钮,具体取决于选择哪一个我想要将它们发送到特定的JSP页面。我不知道如何在我的Java类中选择哪个按钮。
这是JSP:
<form method="post" action="ttp.actions.Sale1Action.action">
<input type="radio" name="radio1" value="packages"checked> packages<br>
<input type="radio" name="radio1" value="productions"> productions<br>
<input type="submit" value=" next "/>
</form>
.
这是java:
public class Sale2Action implements Action {
public String process(HttpServletRequest request, HttpServletResponse response) throws Exception {
String prodPack = request.getParameter("radio1");
System.out.println("radio1 = " + prodPack);
String venueID = request.getParameter("venueid");
Venue v = VenueDAO.getInstance().read(venueID);
if (prodPack.equals("packages")) {
return "sale3a.jsp";
} else {
return "sale3b.jsp";
}
}
}
. 解决方案
In the servlet, to determine which button is selected
String value = request.getParameter("radio1");
You will get the value. If you check packages, the value will be "packages". Radio group return one checked value.
