有三种方法可以将数据从一个JSP发送到另一个JSP
There are three ways to send data from one JSP to another
1.
String name="Hello";
request.setAttribute("Name",name);
通过另一个JSP访问:
From Another JSP Access by:
request.getAttribute("Name");//Hello
2.
String name="Hello";
session.setAttribute("Name",name);
通过另一个JSP访问:
From Another JSP Access by:
session.getAttribute("Name");//Hello
3.
String name="Hello";
localStorage.setItem("Name",name);
通过另一个JSP访问:
From Another JSP Access by:
localStorage.getItem("Name")//Hello
