JavaScript Dictionary

Excellent.  The 4guysfromrolla example is very helpful, thanks.  I've pasted a complete javascript.js file below which allows one to create a dictionary to make calls like the following:

var userDict = new Dictionary();

userDict.Add("smith", "admin");

userDict.Add("jones", "user");

userDict.Delete("jones");

var keys = userDict.Keys

for(var i=0; i<keys.length; i++)

{

 alert((keys[i]+": "+userDict.Lookup(keys[i])));

} 

 

 Admittedly, the keys array is inefficient, but it's very handy in situations where the dictionary is small.
