Need javascript help to post and retrieve xml data from url

**rafhelp** · Mar 20th, 2012, 09:21 AM

Ok the site is score oid and i need to get some information about a game. the server returns data in xml format.

I have tried many different code but cant get it to return anything successfully.

OK here is the code im using (for security reasons i have changed the correct key values, you could test the script with your existing php etc..)

Code:

function getgame()
{

var url ="http://www.scoreoid.com/api/getGame";
var request;

var params ='api_key: "b9d57f3fbf2faa8d607ad2fc6178ab153gt08b48", game_id: "k4scvJUW2", response:"XML"';

request = new XMLHttpRequest();

request.open("get",url,1);

request.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");

request.setRequestHeader("Content-Length", params.length); // POST request MUST have a Content-Length header (as per HTTP/1.1)	
		
request.onreadystatechange = function()
            {
                if (request.readyState === 4) 
				 {
                 if (request.status === 200 ) 
				  {
                  alert(request.responseText);//getAllResponseHeaders());
                  }
                 else 
				  {
                  alert("ERROR");
                  };
                 };
            };
		request.send(params);

}

it should return a xml data structure with the info i need.

The API getGame on the server needs three variables posted api_key, game_id and response

any help appreciated. and please i have given it a lot of tries, im new to javascript

for testing purposes i made a html file with the function to see if the javascript works:

this does not work either, going round in circles im gonna forget it, this langauge is not straight forward enough its like theres is too many parameters and reliance on other things which you may not be aware of.
