Jsp+jquery using AJAX to invoke JSON implementation _jsp programming

This example describes the implementation of Jsp+jquery using AJAX to invoke JSON. Share to everyone for your reference, specific as follows:

Front desk:

<script type= "Text/javascript" src= "jquery-1.5.1.min.js" ></script>
<script type= "text/" JavaScript ">
 //test
 function Test (UID)
 {
  If confirm (" Determines whether the user is manipulating "+uid+"?) )
  {
  var date = new Date ();
  var param = {Uid:uid};
  Jquery.get ("test.jsp?para=" + date, param,
    function (data) {
     if (data!= null)
     {
    var result = Data.result;
    Alert ("data===" +data);
    if (result = = 1)
    {
    alert ("Operation failed");
    }
    if (result = = 0)
    {
    alert ("Operation failed.") ");
    Document.location.href = document.location;
    Window.location.reload ();}}}
  );
} </script>
<a href= "javascript:void (0);" onclick= "Test (111111111111111111);" >submit</a>

Background:

TEST.JSP:

<%@ page language= "java" import= "java.util.*" pageencoding= "UTF-8"%><% response.setcontenttype
(" Application/x-json;charset=utf-8 ");
String uid=request.getparameter ("UID");
int ret=0;
String result = "{\" result\ ":" + ret + "}";
Out.print (result);
%>

Note: Returns the JSON format

such as {"Result": 0}

Need to set:

Copy Code code as follows:

Response.setcontenttype ("Application/x-json;charset=utf-8");

I hope this article will help you with JSP program design.
