Hello,
I am creating html project with ajax. When i deploy the
project with phonegap-android app in Android environment, it just
working fine, but when i deploy the project with phonegap-Blackberry
app in Blackberry environment(Modele above Bold 9000) the ajax is not
working ,
I followed the below link, how can i make xhr call. Can any one
provide example for making ajax in blackberry mobile.
http://groups.google.com/group/phonegap/browse_thread/thread/2bbe89c6e5ca6ca5/50bb52d15fe1fe1f?lnk=gst&q=BlackBerry+ajax#50bb52d15fe1fe1f.
I used below ajax code
function showCustomer()
{
var url="getcustomer.asp";
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
xmlhttp.onreadystatechange=stateChange;
xmlhttp.open("GET",url,true);
xmlhttp.send(null);
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
xmlhttp.onreadystatechange=stateChange;
xmlhttp.open("GET",url,true);
xmlhttp.send();
}
}
How can i make this code working in BlackBerry
Thanks

As it says in known issues:
Native XHRs do not work on PhoneGap BlackBerry. You can have a look at the Java-based, native implementation of XHR that we've implemented here: http://github.com/phonegap/phonegap-blackberry/blob/master/framework/src/com/nitobi/phonegap/api/impl/NetworkCommand.javaThe JavaScript interface looks like this:
navigator.network.XHR(url, postData, callback);
url - string parameter of the URL to send the request to.
postData - string parameter of POST data to send (can be null if you don't want to send POST - just add GET parameters as querystring to the URL parameter if that's the case).
callback - a function handle to execute when the XHR returns.
navigator.network.XHR(url, postData, callback);
url - string parameter of the URL to send the request to.
postData - string parameter of POST data to send (can be null if you don't want to send POST - just add GET parameters as querystring to the URL parameter if that's the case).
callback - a function handle to execute when the XHR returns.
So you need to call:
navigator.network.XHR(url, postData, callback);
Instead of:
xmlhttp=new XMLHttpRequest();
xmlhttp.onreadystatechange=stateChange;
xmlhttp.open("GET",url,true);
xmlhttp.send(null);

Thank you for your quick reply.
Can you please help me whether my code is correct or not.
my code is
function showCustomer(strVal)
{
var url="http://mydomain.com/getXml.asp";
navigator.network.XHR(url, "Get", stateChanged);
}
function stateChanged()
{
How can i get the respose as XML data here.
}
It says "navigator.network" is null or not Object error.
and How can i get the respose as XML data
I am new to ajax and Javascript and also phonegap, sorry if my
questions are weird you.
Thanks

I´d love to ask the same question too..
Could you please give use a practicle example of how to use it?
I would really appreciate it so much...

If 'navigator.network' is undefined, then either phonegap.js is not
loaded completely yet or is not being referenced in your phonegap page
at all. Since the XHR implementation is done natively in Java on the
blackberry, we need to bridge into native using the PhoneGap approach,
so you need to have phonegap.js loaded in.
Very simple example:
<html>
<head>
<!-- make sure phonegap.js is in the same directory as this html page
-->
<script type="text/javascript" src="phonegap.js"></script>
<script type="text/javascript">
// Renders the JSON data returned by the twitter api into the DOM
function twitterCallback(obj) {
var payload = obj.results;
var html = '';
for (var tweet in payload) {
html += tweet.text + ' || ';
}
document.getElementById('content').innerHTML = html;
}
// Runs the XHR command.
function runXHR() {
navigator.network.XHR("http://search.twitter.com/search.json?
q=phonegap", null, twitterCallback);
}
// Makes sure the page is loaded before initiating the XHR.
function loadIt() {
var state = document.readyState;
if (state == "loaded" || state == "complete") {
runXHR();
} else {
setTimeout(runXHR, 250);
}
}
</script>
</head>
<body onload="loadIt();">
<p id="content"></p>
</body>
</html>
To clarify: the 2nd parameter to the XHR() function is the POST data
to write to the body of the request, so should be ONE OF:
a) null. If you are making a GET request, pass in the null literal
(since you are not writing any POST data).
b) a string. this represents the POST data you are attaching to the
request.
Hope that helps.

Thank you filmaj,
I did what you given above, but the callback method
not fired. My remote file can be accessed from Android and other
browser. I am using your lates phonegap-blackberry project.

Are you running from simulator or from device?
If from simulator, make sure you have the MDS-CS program running in
the background - this is the internet proxy that allows the simulator
to communicate with the interwebz. You can manually run it from your
eclipse directory if you are using the BlackBerry Eclipse plugin, it
should be located in eclipse/plugins/
net.rim.eide.componentpack<version>/components/MDS/run.bat. Make sure
you run it from the proper directory inside the plugins/ directory,
that is, for example, if you are running the 4.6.1 simulator, make
sure you run the run.bat file located in
net.rim.eide.componentpack4.6.1/components/MDS/
If you are running on device, make sure your APN settings are set
correctly, Menu -> Options -> Advanced Options -> TCP/IP

Hey Karthik,
There may be a disconnect between the headers of the request being
sent out and the headers of your server's response. Have a look at
this link:
http://github.com/phonegap/phonegap-blackberry/blob/master/framework/src/com/nitobi/phonegap/api/impl/NetworkCommand.java#L225
This is the code that runs the custom PhoneGap XHR implementation. At
line 225, I would suggest you place a breakpoint and run your app in
the simulator in debug mode. At this line, we check the response code.
If it is anything other than 200, no JavaScript call will be made back
in the PhoneGap browser. In my experience, this happens sometimes if
the ACCEPT- headers in your request don't match up to the same headers
that your server accepts. The dozen or so lines above line 225 are
well commented with various options on what to set the request headers
to.
Usually I just check the HTTP response code, and that gives me a good
enough clue as to what the problem is, if the response code is
something other than 200.
Hope that helps!
Let me know how it goes.
Cheers,

to phonegap
filmaj , or any body, Pleae can you give an example of how did you
write your code to let it work for xml document post ? (sorry of
asking too much)
Following you example I did the following but it didn´t work :
function xmlCallback(obj) {
var payload = obj.results;
var html = "";
alert("lanzado");
html += codigo.text + " || ";
}
document.getElementById('content').innerHTML = html;
}
// Runs the XHR command.
function runXHR() {
usuario><contrasena>password</contrasena></login></record>"
navigator.network.XHR("the url of the service", postData,
xmlCallback);
}
// Makes sure the page is loaded before initiating the XHR.
function loadIt() {
var state = document.readyState;
if (state == "loaded" || state == "complete") {
runXHR();
} else {
setTimeout(runXHR, 250);
}
}

azayed,
the current implementation is very rough, it is just a temporary
solution for my own purposes that we basically opened up for other
people to use. Thus, the current implementation is made to work with
JSON responses (something that the JS interpreter can easily
evaluate). For XML, I have no solution...
The main problem with trying to parse XML within the BlackBerry
browser is that there is only DOM level 2 which only supports certain
types of DOM objects. The problem is that the RIM browser doesn't have
a native DOMParser object (which is DOM level 3), so parsing XML is
difficult unless you build or find some kind of javascript library
that will do text-based parsing (or some such).
For my own previous client projects, what I did was added a
conditional statement to the NetworkCommand.java NetworkThread
implementation, that checked the server response MIME type after the
request is dispatched - if it was text/xml, then I would do the XML
parsing on the *Java* side and then simply marshall a JSON
representation that I would build up back into the browser after the
parsing was complete. Definitely sucks, but actually as long as you
import some of the "sax" XML parsing libraries that are available to
you via the RIM API the code is quite manageable and simple to write.
Hopefully you're cool with Java programming!
Man I can't wait for the new RIM webkit browser... I hope to see it
out there within 6 months!
