You should read Jim Ley's article about [url=http://jibbering.com/2002/4/httprequest.html]using the XML HTTP Request object[/url]. He provides a method to instanciate an XMLHttpRequest object that work in Internet Explorer on Windows, Safari on Mac OS-X, Mozilla on all platforms, Konqueror in KDE, IceBrowser on Java, and Opera on all platforms including Symbian. Beside the instanciation that is crippled in IE, the browser vendors have implemented the same methods. As there was no open standard they slightly differ in some parts ( such as when the readyState is reset to 1 when you re-open() a connection, ... ). [b]H][RO:[/b] You can use the XML 'mode' if the server return a [i]Content-type: text/xml/[/i] or [i]application/anything+xml[/i], and of course the XML document must be valid. A node not closed, or a gremlins in the attributes and bam! the [i]responseXML[/i] property of you XMLHttpRequest object will be [i]null[/i]. But it's really simple to generate a valid XML document.[quote]i mean JSON uses async etc.. [/quote]:confused: JSON is just a de/serializer of JavaScript objects. You can use it anywhere, regardless of the synchronous state of your code. And FWIW I don't really like JSON for it uses eval(). Eval() is evil. It has some security issues. On one hqnd I recognize that JSON is convenient because you don't have to parse a hell of XML document, but writing a parser is not hard and much cleaner.
