Calling WebService using plain JavaScript

[Chetan Parekh]

I need to call a WebService of a different domain from my application using plain JavaScript. I don’t have a liberty to use any JavaScript/Ajax libraries - I can only use plain JavaScript.

Solution must work on IE and Firefox both.

Since XmlHttpRequest falls under the same-domain policy, you'll have to use JSONP.

Wouldn't the web service need to support JSONP? If yes - it sounds like a good approach - otherwise traditional server proxy approach would work.

I found this an interesting read.

In case its not clear by what I meant by a server proxy -- you'll find some good help here -- http://www.google.com/search?q=cross+domain+javascript&ie=utf-8&oe=utf-8&aq=t
