[Javascript] Database Access

[pd]

I have not worked with dataSrc and dataFld objects.  According to my 
documentation, the dataSrc is used to specify the remote ODBC data 
source.  Is it very hard to set up with MySQL?  Does it work with the newer 
Netscape browsers?  How difficult is it to retrieve a list of phone 
numbers, for example in a given area code and place them in an HTML 
<SELECT> statement for the user to choose from?

Thanks,

Paul
