It turns out that the Jquery.load method can keep loading_jquery

As long as there is no conflict (for example, the ID cannot be the same), I wrote an example to use page parameters to control the internal element ID and load each other. This is a jsp page, the code is as follows:

<% @ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() "://"
request.getServerName() ":" request.getServerPort()
path "/";
int i = Integer.parseInt(request.getParameter("i ")==null?"0":request.getParameter("i"));
%>







< ;meta http-equiv="expires" content="0">

this is index.jsp ?i=<%= i %>

load index.jsp?i =<%= i 1 %> here!

However, if you only take part of the page, for example, change the click code of the button to:

Then, only a button is loaded, not the entire page. As shown in the picture:
