google closure compiler and jquery-Collection of common programming errors

I copy-pasted my js code into the google compiler and when I copied it back into my application it didn’t work. I realized that my code needs jquery so I copied the jquery code and my code into the google compiler, hoping it would easily solve the problem, but it doesn’t work either.

In chrome, the code bugs on the line $(document).K(function () { which is the document ready function. The error is Uncaught TypeError: Object [object Object] has no method 'K'

What do I need to do to make it (tentatively) work?

Thanks for your suggestions.
