Rendering multiple banners with one slot ID

You can render multiple banners using the same slot ID and dimensions by setting up a banner context. This is useful when you want to run an auction with multiple results. To do that you have to pass the attribute context="true" to the topsort-banner and use topsort-banner-slot as children elements.

<topsort-banner context="true" width="600" height="400" id="<your slot id>">
  <topsort-banner-slot rank="1"></topsort-banner-slot>
  <topsort-banner-slot rank="2"></topsort-banner-slot>
  <topsort-banner-slot rank="3"></topsort-banner-slot>
</topsort-banner-context>

Listening to events

The banner component emits an event when the state changes. You can listen to this event to write custom logic. The various states are loading, ready, error, and nowinners.

document.querySelector('#my-slot-id').addEventListener('statechange', (event) => {
  console.log(event.detail); // { status: 'ready', banner: { ... } }
});

Running the example

You can play around with the provided index.html file. To run it, you'll need to install the dependencies and start a local server.

git clone https://github.com/Topsort/banners.js.git
cd banners.js
pnpm install
pnpm run dev

Remember to add window.TS.token and modify the slot-id attribute with your own values that you can find at Topsort.
