从javascript调用jsp方法 [英] call a jsp method from javascript

问题描述

我在jsp页面中使用这样的方法，页面以new.jsp的名义保存

I use a method in jsp page like this and the page is saved in the name of new.jsp

<%!
    public void createXml(String graph) throws Exception
    {
        try
        {
            String str="dinesh"

            DocumentBuilderFactory builderFactory = DocumentBuilderFactory.newInstance();
            DocumentBuilder docBuilder = builderFactory.newDocumentBuilder();
            Document doc = docBuilder.newDocument();
        }

        catch(Exception e)
        {
            System.out.println(e);
        }
    }
%>

如果我这样称呼这个页面

If i call this page like this

<form method="post" action="new.jsp">

但是，我想只使用javascript或jquery编码来调用createXml的这个方法，因为我要添加new.jsp中的各种方法。任何人都可以在不调用整个jsp页面的情况下帮助调用方法

But, I want to call this method of createXml only using javascript or jquery coding because i am going add various method in the new.jsp. Any one help this to call method without calling the whole jsp page

推荐答案

您正在寻找的是如何创建ajax请求。您可以不使用jquery 或使用jQuery轻松实现：

What you're looking for is how to create an ajax request. You can do it without jquery or easily with jQuery:

$.post('new.jsp',{ param1: 'param1value', param2: 'param2value'},function(data){
    if(data){
        console.log(data); // response from your server
    }
  });
