Interacting with the Internet
This code snippet can be used to send or retrieve information to or from the internet.
In order to communicate with a server from JScript, you first need to know the Universal Resource Indicator (URI) of the server. For example: http://www.mpscripts.net/newthread.php?fid=10
It's worth noting that the "http://" must be included.
Second, you need to know what the server expects to hear from the script. For example the http://www.myspace.com servers will deny your script access if you don't include a header called "Referer" stating where the request is coming from, such as Referer="chrome://myscriptname"
Finally, you need to know what you can expect to hear back from the server. Most of the time knowing what to send and recieve will be trivial because you'll be working with purpose-built scripts. However, if you plan to work with someone else's servers (try to obtain permission first!) such as scraping a web page for information, the server may send the entirity of the page back following your request! At other times you may get something as simple as a yes or no answer, all epending on the intention of your script.
So here's the code and what each piece does:
Code:
var request = new ActiveXObject("Microsoft.XMLHTTP");
var serverResponse = "";
function getData()
{
var TYPE = "GET"; //use GET to request information and POST to send information
var URI = "Http://www.myserverexample.com/form.php"; //whatever server and or form you want to communicate with
var ASYNC = true; //if false script will pause until the request is complete
var TOSERVER = "specific-info-the-server-expects-to-hear"; //info to send to the server
request.open(TYPE, URI, ASYNC);
request.send(TOSERVER);
request.onreadystatechange = processReadyStateChange();
}
function processReadyStateChange()
{
if(request.readyState == 4 && request.status == 200)
{
serverResponse = request.responseText;
}
}
You now have the server's response stored as a string in the variable "serverResponse".

RE: Interacting with the Internet
Shouldn't it be:
request.onreadystatechange += processReadyStateChange();

RE: Interacting with the Internet
No, because then it would add the functions name after anything already inside the var. We just want it to use the specified function.
I didn't believe it either, oh wait I did.
