pbjs.onEvent(eventType, handler, id) for Header Bidding

pbjs.onEvent(eventType, handler, id)

This routine allows the page (or module) to create a callback function that’s invoked when heading bidding events are fired.

Kind: static method of pbjs

Args: eventType, callbackFunction, id

Returns: none

See the getEvents function for the full list of eventTypes supported.

The adRenderSucceeded event indicates that the render function did not generate an error, it does not guarantee that tracking for this event has occurred yet.

The optional id parameter provides more finely-grained event callback registration. This makes it possible to register callback events for a specific item in the event context.

For example, bidWon events will accept an id for ad unit code. bidWon callbacks registered with an ad unit code id will be called when a bid for that ad unit code wins the auction. Without an id this method registers the callback for every bidWon event.

Currently, bidWon is the only event that accepts the id parameter.

Example 1: Basic event logging

        /* Log when ad units are added to Prebid */
        pbjs.onEvent('addAdUnits', function() {
          console.log('Ad units were added to Prebid.')
          console.log(pbjs.adUnits);
        });

        /* Log when Prebid wins the ad server auction */
        pbjs.onEvent('bidWon', function(data) {
          console.log(data.bidderCode+ ' won the ad server auction for ad unit ' +data.adUnitCode+ ' at ' +data.cpm+ ' CPM');
        });

Example 2: Dynamically modify the auction

        var bidderFilter = function bidderFilter(adunits) {
            // pub-specific logic to optimize bidders
            // e.g. "remove any that haven't bid in the last 4 refreshes"
        };
        pbjs.onEvent('beforeRequestBids', bidderFilter);

Example 3: Log errors and render fails to your own endpoint

        pbjs.onEvent('adRenderFailed', function () {
              // pub-specific logic to call their own endpoint
            });
        pbjs.onEvent('auctionDebug', function () {
              // pub-specific logic to call their own endpoint
            });
