Example 1 - Server side JSP encoding
service.jsp:
<%@page contentType="text/html; charset=UTF-8"%> <%@page import="org.json.simple.JSONObject"%> <% JSONObject obj=new JSONObject(); obj.put("name","foo"); obj.put("num",new Integer(100)); obj.put("balance",new Double(1000.21)); obj.put("is_vip",new Boolean(true)); obj.put("nickname",null); out.print(obj); out.flush(); %>
Please note that you need to place json_simple-1.1.jar in WEB-INF/lib before running the JSP. Then the client side will get the resulting JSON text.
Example 2 - Client side XMLHttpRequest
client.html:
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> </head> <script type="text/javascript"> function createXMLHttpRequest(){ // See http://en.wikipedia.org/wiki/XMLHttpRequest // Provide the XMLHttpRequest class for IE 5.x-6.x: if( typeof XMLHttpRequest == "undefined" ) XMLHttpRequest = function() { try { return new ActiveXObject("Msxml2.XMLHTTP.6.0") } catch(e) {} try { return new ActiveXObject("Msxml2.XMLHTTP.3.0") } catch(e) {} try { return new ActiveXObject("Msxml2.XMLHTTP") } catch(e) {} try { return new ActiveXObject("Microsoft.XMLHTTP") } catch(e) {} throw new Error( "This browser does not support XMLHttpRequest." ) }; return new XMLHttpRequest(); } var AJAX = createXMLHttpRequest(); function handler() { if(AJAX.readyState == 4 && AJAX.status == 200) { var json = eval('(' + AJAX.responseText +')'); alert('Success. Result: name => ' + json.name + ',' + 'balance => ' + json.balance); }else if (AJAX.readyState == 4 && AJAX.status != 200) { alert('Something went wrong...'); } } function show(){ AJAX.onreadystatechange = handler; AJAX.open("GET", "service.jsp"); AJAX.send(""); }; </script> <body> <a href="#" onclick="javascript:show();"> Click here to get JSON data from the server side</a> </html>
Please place client.html and service.jsp (see Example 1) in the same directory and then open client.html in IE or Firefox, click the link and you'll get result.
