I have the following code which iterates for subsites:
while (enumSubSites.moveNext())
{
var Site = enumSubSites.get_current();
I want to get the associates list items from Site. Do I need to somehow set client context to retrieve list items?
Try like following
Get the list
var list = context.get_web().get_lists().getByTitle('List Name');
Create Query
var caml = new SP.CamlQuery();
caml.set_viewXml("<View><Query><Where><BeginsWith><FieldRef Name='Title' /><Value Type='Text'>T</Value></BeginsWith></Where></Query></View>");
Specify the query and load the list oject
returnedItems = list.getItems(caml);
context.load(returnedItems);
Run asynchronously
context.executeQueryAsync(onSucceededCallback, onFailedCallback);
