You can use subscription.newsExpression (expression) to set expression for selecting news headlines that will be received from container. For example:
var s = JET.News.create() .newsExpression("BOJP OR ABNNEW") .onAppend(function (upd) { console.log(upd.h); }) .onInsert(function (upd) { console.log(upd.h); }) .start();
The above code will receive news headlines from ABN Newswire and Bank of Japan Announcements.
You can find valid expressions from filters in News Monitors application.
