问题
I have two radio buttons, and depending on which one is selected I want to send them to a specific jsp page. I do not know how to pull which button is selected in my java class.
Here is the 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>
here is the 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";
}
}
}
回答1:
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.
