How to pass parameters to components?

[eric_estes]

I'm rendering out a component via a data-sly-resource and I'd like to be able to pass parameters as part of this, for example something like <sly data-sly-resource="${'featuredPost' @ showComments=false}"></sly> or something. I'd rather keep it out of the dialog because it's not something authors need to worry about and I'd rather not create separate resource types to handle different rendering scenarios for the same content. Is there a way to do this?

Use-api

In my second article I explained that you can call methods from your custom-classes via the data-sly-use notation.
In this example I will show that you can also pass in parameters from your components.

However - values are passed from front end to the back end - which is Java. 

If you want to get values to the component itself (ie - a String value)- you need to use a dialog.

Looks like the method shown in that link would just pass parameters into the use file, which is called from within the component, and not into the component itself?

Correct - that blog talks about getting values to the Java part of the Sightly code. 

The way to  get values passed to the Sightly component is to use a dialog and code like: 

<div id="experiencetext">${properties.contactDescription}</div>

See this Sightly article for more details:

I'd rather not use a dialog because it is not an authorable property.

Take a look at the following thread - http://stackoverflow.com/questions/25404863/aem-6-0-additional-parameters-when-using-data-sly-resour...

Another option to explore is using Java and then use OSGi config values:

You can set values in the JCR which are picked up by Java logic.
