Get a data-sly-list element as a jsonarray

How can we pass a list from HTL to a sling model?

I need a nested list to be converted into JsonArray format. 

<div data-sly-list="${values}">
     <h1>${item.title}</h1>
     <p>${item.description}</p>
</div>

Now I want the same thing as a json string from ${values}:

[{"title":"test1", "description":"desc1"},{"title":"test2", "description":"desc2"}]

Any inputs would be helpful.

    In your java class you can convert the data to json using GSON and send back to frontend -

    Gson().toJson("data");

        Create a sling model and adapt usiing SlingHttpServletRequest.class

        Example:

        <!-- info.html -->

        <div data-sly-use.info="${'TestModel' @ text='Some text'}">

            <p>${info.reversed}</p>

        </div>

        Sling model

        import org.apache.sling.api.SlingHttpServletRequest; 

        import org.apache.sling.models.annotations.Model; 

        import org.apache.sling.models.annotations.Optional; 

        import org.apache.sling.models.annotations.injectorspecific.RequestAttribute; 

         

         

        @Model(adaptables = SlingHttpServletRequest.class) 

        public class TestModel { 

        @RequestAttribute 

        @Optional 

        private String text; 

        @PostConstruct 

            public void init() { 

                //we can read the values directly here. 

            } 

        }

            Hi,

            Please refer below to pass data from sightly to sling model:

            https://sling.apache.org/documentation/bundles/scripting/scripting-htl.html#passing-parameters

            After passing the data to sling model you can write your custom code in Sling model to convert it to json.

            Regards,

            Arpit Varshney
