我在这样的jsp页面中使用了一个方法，该页面以new.jsp的名称保存
<%!
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);
}
}
%>
If i call this page like this
如果我这样称呼这个页面
<form method="post" action="new.jsp">
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
但是，我想只使用 javascript 或 jquery 编码来调用 createXml 的这个方法，因为我要在 new.jsp 中添加各种方法。任何人都帮助这个调用方法而不调用整个jsp页面

What you're looking for is how to create an ajax request. You can do it without jqueryor easily with jQuery:
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 轻松完成此操作：
$.post('new.jsp',{ param1: 'param1value', param2: 'param2value'},function(data){
if(data){
console.log(data); // response from your server
}
});
There's a lot more info in the jQuery docs
jQuery 文档中有更多信息
