This article mainly brings you an implementation of processing data after ajax is submitted to the java background. The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor to take a look, I hope it can help everyone.
Environment: eclipse+struts
The effect to be achieved: click the button to submit the data to the background and then return to the foreground to display the data
index.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<input type="text" id="userinput">
<input type="button" id="submit">
<p id="msg"></p>
</body>
<script type="text/javascript" src="jquery-2.1.0.js"></script>
<script type="text/javascript">
window.onload = function() {
document.getElementById("submit").onclick = test;
}
function test(){
var userinput = document.getElementById("userinput");
$.post("http://localhost:8080/TestSpring/TestAction",{username:userinput.value},
function(data, textStatus){
document.getElementById("msg").innerHTML = data;
});
}
</script>
</html>
struts.xml
<action name="TestAction" class="com.action.Test"> <result>index.jsp</result> </action>
Test.java
package com.action;
import java.io.PrintWriter;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts2.ServletActionContext;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
public class Test extends ActionSupport {
@Override
public String execute() throws Exception {
// TODO Auto-generated method stub
HttpServletRequest request = org.apache.struts2.ServletActionContext.getRequest();
HttpServletResponse response = ServletActionContext.getResponse();
request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf-8");
PrintWriter out = response.getWriter();
out.write(request.getParameter("username"));
out.flush();
out.close();
return SUCCESS;
}
}
