+1 obviously.
I encountered this need multiple times. One such example is the Document
Tree which uses the jstree library which accepts as node icon an URL, a
path or a CSS class name. I believe it is common in the JavaScript world to
be able to specify an icon either as an URL/path or as a CSS icon. The
reason Adel proposed "renderJSON" is because this method is needed mainly
when you generate JSON and the client that receives the JSON wants to have
100% control over the HTML that is generated (so injecting the HTML we get
from renderHTML is not an option).
Note that besides renderJSON we would also need a method to pull the
resources required by the icon set. I propose something like:
$services.icon.use() <--- pull the resources for the configured icon set
$services.icon.use('someIconSet') <--- pull the resources for the specified
icon set
These methods will call ssx, jsx, etc. under the hood. This is done already
when you call render() and renderHTML() but it obviously doesn't work if
you call render* on an AJAX request that returns JSON.
Thanks,
Marius
