将 PHP/ASP AJAX 示例转换为 JSP

Question

嗨，我是JSP的新手，我正在尝试将W3School的Ajax示例转换为jsp，但我无法这样做。任何人都可以帮忙。

这是 PHP 示例

http://www.w3schools.com/php/php_ajax_php.asp

下面是 ASP 示例

http://www.w3schools.com/ajax/ajax_asp.asp

我尝试过使用 java 的子字符串函数，但失败了。

提前谢谢。

我的理解是你想将 PHP/ASP 代码转换为 jsp。这是 jsp 代码。请将此代码保存在gethint.jsp页面中，并在html页面中更改URL以针对jsp页面

<%@page import="java.util.Arrays"%>
<%
// Array with names
String hint = " "; 
String[] a = {
    "Anna","Brittany","Cinderella","Diana","Eva","Fiona","Gunda",
    "Hege","Inga","Johanna","Kitty","Linda","Nina","Ophelia"
    ,"Petunia","Amanda","Raquel","Cindy","Doris","Eve","Evita","Sunniva"
   ,"Tove","Unni","Violet","Liza","Elizabeth","Ellen","Wenche","Vicky"
   };
   // get the q parameter from URL
   String q = request.getParameter("q");
   if (q != " ") {
   for(String name : a )
   {
     if(name.toLowerCase().startsWith(q.toLowerCase()))
     {
        if(hint == " ")
        {
           hint = name;
        }
        else
        {
            hint = hint + ", " + name;
        }
    }
  }
 }
 if(hint == " ")
 {
   out.println("No suggestion");    
 }
 else{
 out.println(hint);
  }
  %>
