Redirecting to another page with JavaScript and JSP
提问by Abdullah Malikyar
I am trying to redirect the user to my log in page as soon as the registration is done, using either JSP or JavaScript.
我试图在注册完成后立即使用 JSP 或 JavaScript 将用户重定向到我的登录页面。
I should mention that the registration form is calling the same page and when I say window.location, glassfish throws error as resource not found.
我应该提到注册表正在调用相同的页面，当我说时window.location， glassfish 会因为找不到资源而引发错误。
{
if(request.getParameter("submit")!=null)
{
String uname=request.getParameter("txtusername");
String password=request.getParameter("txtpassword");
String mail=request.getParameter("txtemail");
String dob=request.getParameter("dob");
String city=request.getParameter("txtcity");
String state=request.getParameter("txtstate");
String country=request.getParameter("txtcountry");
String address=request.getParameter("txtstreetaddress");
String scity=request.getParameter("txtscity");
String sstate=request.getParameter("txtsstate");
String scountry=request.getParameter("txtscountry");
String saddress=request.getParameter("txtsaddress");
String mobile=request.getParameter("txtno");
String gender=request.getParameter("rdbgender");
adminClasses.user u= new adminClasses.user(0, uname, password, mail, dob, city, state, country, address, scity, sstate, scountry, saddress, mobile, gender);
int result=adminClasses.userfunctions.addNewUser(u);
%>
<script>
var res=<%=result%>;
if(res==0)
{
window.alert("Registration Unsuccessful");
}
else
{
window.alert("Resgistration Successful!Click Ok to Sign in");
window.location="signin.jsp";
}
</script>
<%
}
}
catch (Exception e)
{
out.println(e.getMessage());
}

I think you could do it this way:
我认为你可以这样做：
...
int result = adminClasses.userfunctions.addNewUser(u);
if (result == 0) {
request.getRequestDispatcher("signupSuccess.jsp").forward(request, response);
}
...
It will evaluate the resulton the server side and then, depending on the result, will forward to a signupSuccess.jsppage – i.e. the URL will stay the same, but the response will include success page's evaluated content.
它将result在服务器端评估，然后根据result，将转发到一个signupSuccess.jsp页面——即 URL 将保持不变，但响应将包括成功页面的评估内容。

You can try this
你可以试试这个
response.sendRedirect("signupSuccess.jsp");

check your path for current page like code below ; because i think you may be writing the path wrong in
检查当前页面的路径，如以下代码；因为我认为你可能写错了路径
window.location="signin.jsp"
// Example
// Return the entire URL (of the current page):
<script>
document.write(location.href);
</script>
// The output of the code above is:

I have done like following code using java.
我已经使用java完成了以下代码。
response.getWriter().write("<script> window.location="redirect_url"</script>");
