How to write a javascript tracking code?

Question

I want to write a simple javascript tracking code that should be able to push parameters to a remote server.

• What should I pay attention when writing this code?
• Is there a difference with the new asynchronous codes around (google analytics style)?
• Can you provide a very basic example code?

Thank you

I would suggest to use jQuery ajax features. Comes with good documentation and examples.

You can send stuff synchronously or asynchronously, via GET, POST etc. See the linked documentation.
