Hi AEM Gurus,

I have a JSON Array like below sample

{
"sites": {
"label": "Parent LABEL",
"mobileLabel": "Parent Mobile Label",
"items": [
{
"href": "www.google.com",
"id": "goog",
"label": "Google Search"
},
{
"href": "www.yahoo.com",
"id": "yah",
"label": "yahoo site"
},
{
"href": "www.wikipedia.com",
"id": "wiki",
"label": "wikipedia"
}
]
}
}

Now i am trying to Iterate and get the values from this JSON array using data-sly-list something like as shown in below structure

<ul data-sly-list.key="${model.jsonarray}">
<li><a href="${key.href}">${key.label} - ${key.id}</a></li>
</ul>

I know we can iterate Arraylist or a Map object but how do I iterate a JSON array. Please suggest.

You would need to serialize the JSON string to either a List<HashMap> or List<Link>. Once you return a valid List object to your slightly business logic, your code should work as expected.

However, if your list looks something like List<Json> then that would also work as well. You ultimately just need to have a valid List object with valid item objects.

Hi @rajaram33,

You can use the below code, convert JSONArray to List and pass it to sightly.

ArrayList<String> listdata = new ArrayList<String>();
if (jArray != null) {
for (int i=0;i<jArray.length();i++){
listdata.add(jArray.getString(i));
}
}

Hope this helps.

Thanks,

Kiran Vedantam.

Hi @briankasingli @kiran_vedantam ,

I tried as suggested by creating a Link with hashmap

public List<HashMap<String, String>> getListItem(JSONObject taxanomyDat) {
log.info("Inside Model getDemoItem");

List<HashMap<String, String>> prodArrayList = new ArrayList<HashMap<String, String>>();

Map<String, String> siteLink = new LinkedHashMap<String, String>();

siteLink.put("label1", "www.gmail.com");
siteLink.put("label2", "www.yahoo.com");
prodArrayList.add((HashMap<String, String>) siteLink);

return prodArrayList;
}

public List<HashMap<String, String>> getDemoItem() {
return demoItem;
}

And in HTL i am not sure What mistake i am doing or how to get the key and value inside haspmap of arraylist.

<div class="cmp-helloworld__item" data-sly-use.model="com.myapp.core.models.SampleModel">
<p class="cmp-helloworld__item-label">Model message:</p>
<ul data-sly-list="${model.demoItem}">
<li >${item.siteLink}</li>
</ul>
</div>
