A web script is invoked when a URI is requested that matches one of the URI templates
defined by the web script. The web script may need to access the requested URI to allow it to
extract arguments that may have been passed in as URI query parameters or embedded as values
in the URI path.
Your Folder Listing web script defines the following URI template with one URI-path
token and one query parameter token:
<uri>/dir/{folderpath}?verbose={verbose?}</uri>
The args root object is a special object provided by the Web Script
Framework to all controller scripts. It represents a map of the URI query-parameter values
indexed by their name. In this case, the controller script is extracting the
verbose query parameter. If the query parameter is not specified on the
URI, the returned value is null.
To extract the values provided for the {folderpath} and {verbose} tokens, your Folder Listing controller script uses the following JavaScript:
...
var verbose = (args.verbose == "true" ? true : false);
var folderpath
...
The url.templateArgs root object is another special object provided by the Web Script Framework. It represents a map of all values provided for tokens in the URI path, indexed by token name. In this case, the controller script is extracting the value for the folderpath token. URI-path values are never null.
Imagine a client has made the following URI request: /dir/Company%20Home?verbose=true
The resulting value of verbose is true and the value of folderpath is Company Home.
