plain text retrieval from a webservice

[temoor]

function checkValues (Address) {

var values = "hello";
var urlItem = "http://rpc.geocoder.us/service/csv?address=";
urlItem += Address.value + "\n";


values = open (urlItem.toString ());
values=values.toString();
alert(values);
onLoad();


}


i am trying to get geocodes from geocoder.us which is returning plain
text, i need the values
returned and save them in a string, i tried using values =
open(urlItem.toString) and print values in an alert as you can see but
the alert prints "[object]", can anybody tell me how to get the result
in my string variable.

Basically this is the result i am getting, a window opens with this
text in it :
"38.898748,-77.037684,1600 Pennsylvania Ave NW,Washington,DC,20502"

now i want this result in a variable. Hope somebody can help me out
with this.

Thanks

The best object to use for this kind of "invisible" request is
XmlHttpRequest. It allows you to send a request and get the result in a
callback without having to open a new window or refresh the page.

or generally Google for AJAX (asynchronous JavaScript and XML)
