页面为什么不跳转？

[haomeina]

String answer=request.getParameter("Result");
String sql="select * from Visit_All where Answer2='"+answer+"'";
ResultSet rs = stmt.executeQuery(sql); //获取记录总数
if(rs.next()){
session.setAttribute("answer",rs.getString("Answer2"));
response.sendRedirect("../photo/photo_found.jsp");
}else{
out.print("<script language='javascript'>alert('答案错误！');location.href = 'password_visit.jsp';</script>");
}

这样写有什么错误么？页面为什么不跳转？
如果获得答案是错误的也执行ELSE的语句，但是当输入正确的答案时又重新回到了原来的页面，而不做跳转。

out.print(" <script language='javascript'>alert('答案错误！');location.href = 'password_visit.jsp'; </script>");
加个return;
