Description: get the Argument.name=value-pairs of a querystring of the Url 

Argument: sep  Separator-token of the name=value-pairs (default-value: &)
Returns: an object where the properties are the name of the name=value pairs 
Example: args = getArgs(); alert('Your name is ' + args.name)         
Ideas: Load one or more  ressources (pics, iframes etc.) variable according to querystring parameters  
Further proposals: get also values with multiple properties (e.g. to get values of a multis selected Select-Element)
