Ajax issue with multiple requests…

@pbdeveloperauthorAug 19.2011 — #your goign to have to show your code on this one.[/QUOTE]

I have included some code below to show an example. Upon loading the page the server is requested to progress. The initial state is displayed ok. ?

The server then processses and updates the text file (updateStatus.txt) file. I can see this by directing the browser to the file.

My the web page doesnt update though. I expect this because I only have one ajax call.

The server finishes processing.

When I click the button the div is updated with the last message. Again this is what I expect. ?

So, I would be extremely grateful if someone please tell me how do I go about doing multiple requests.

[CODE]
 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" 
 "http://www.w3.org/TR/html4/loose.dtd">
 <jsp:useBean id="updater"
 class="com.product.Updater" scope="page" />
 <jsp:setProperty name="updater" property="servletContext"
 value="<%=getServletContext()%>" />
 <html>
 <head>
 <script type="text/javascript">
 var xmlhttp;
 
  function getUpdates() {
   var c = 0, t = 20;
   // Create a timer
   window.setInterval(function() {
   document.getElementById("myDiv").innerHTML = xmlhttp.responseText;
   }, 50);
  }
 
  function loadXMLDoc() {
   if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
   xmlhttp = new XMLHttpRequest();
   } else {// code for IE6, IE5
   xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
   }
   xmlhttp.onreadystatechange = function() {
   if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
   document.getElementById("myDiv").innerHTML = xmlhttp.responseText;
   }
   }
   xmlhttp.open("GET", "updateStatus.txt", true);
   xmlhttp.send(); 
  }
 
 </script>
 </head>
 <body onLoad="getUpdates();loadXMLDoc();<%updater.start();%>">
 <div id="myDiv">
 <h2>AJAX do a test</h2>
 </div>
 <button type="button" onclick="loadXMLDoc()">Change
 Content</button>
 </body>
 </html>
 [/CODE]

Thanks,

@DanInMAAug 21.2011 — #do you mean it is not updating automatically? it only updates when you clcik change content?

if so this is because getUpdates() will not work. the response text is not a global variable to getupdates cannot access it. I thik what you need to do is set a timer on the loadxmldoc function instead of how you are doing it now
