Sightly :: JavaScript Use-API :: passing an element attribute to JS file

[Sandro Boehme]

Hello,

for the Sling Sitebuilder I would like to pass an id that is specified 
as an element attribute to the Sightly server side JavaScript file 
defined by the JS Use-API. Is that possible?

This example works:

<sly class="component" data-component-type="bs-p" data-component-id="4" 
data-sly-use.componentResource="${'component.js' @id='4'}">
    ...
</sly>

component.js:
"use strict";
use(function () {
    return resource.getChild(this.id);
});

content:
{
        "jcr:primaryType":"sling:Folder",
        "4":{
                "jcr:primaryType":"nt:unstructured",
                "value":"foo bar"
        }
}


But in the 'use' block of the 'sly' tag I specify the '4' as literal 
(@id='4'). Instead I would like to reference it e.g. like 
@id=attributes.data-component-id. Is that possible?

Thanks in advance for any help!

Best,

Sandro
