I can do 'Hello World' - now I need the re...
Why is class based OO so popular instead of prototype based OO? Do they teach the latter in schools? Javascript is object based, but people use it mostly functionally, or via frameworks. I know that Sun has had some research on Self, but is there any other source of knowledge; preferably something that is accessible for self learned. I...

I have created a regexp which can identify the entire <form> tag and all the code up to the ending </form> but I cannot figure out how to match all the <input[^>]+> within that. EDIT: The data is a string. I cannot use DOM functions because it's not part of the document. ...
How do I get an extJS combo field to clear its 'value' when the display text is blank or doesn't match a list value, i.e. custom text not in the data store? I'm sure there must be something I'm missing, because such a simple feature can't make an otherwise impressive combo useless. ...
