InterstitialAd.onLoad
Listen for the interstitial ad load event.
Fired after the interstitial ad loads successfully. A resolved load() Promise does not mean the ad loaded; rely on this event instead, and call show() only after receiving it.
Parameters
function listener
The listener for the interstitial ad load event.
Example
javascript
interstitialAd.onLoad(() => {
console.log('Interstitial ad loaded successfully');
});
