callback function for google.ads.search.Ads()

Question

Following the docs on https://developers.google.com/custom-search-ads/docs/implementation-guide I created some code to retrieve ads on a search result page.

This code assumes that you place a container on your webpage where the function

new google.ads.search.Ads(pageOptions, adblock1, adblock2);

appends an iFrame to that may contain ads. I say MAY contain, because sometimes the iFrames stay empty.

Question: Now I need to know whether there are any ads displayed in the containers or not. How do I do this?

• The call is asynchronous, so when should I initialise the check? (the google reference does not note a callback function)
• How do I check if there's an ad shown. Because with Javascript I can't look inside the iFrame.

Any suggestions welcome! :)

Answer 1

the callback function, that maybe helps you is:

'noAdLoadedCallback':
  function(containerName, adsLoaded) {
      if (!adsLoaded) {
          try {
              ---- do something here ---
          }
          catch (e) {}
      }
  }

You can put this on each adblock.
