Follow up to #11380.

NOTE: This only applies to visibility triggers as well as static content (i.e. no mustache template selectors, no dynamic content). At this time, visibility triggers only work for amp-elements.

Summary

  • Multi-selector support: Add support for a single visibility trigger to support multiple selectors
  • QuerySelectorAll support: Add support for a visibility trigger’s selector(s) to track all elements have the selector(s) (instead of the first element)

Design document

External Doc

Design Proposal

  • Multi-selector: Add array support for the selector field within a visibility trigger
  • QuerySelectorAll: All selectors within the multi-selector array will be treated as querySelectorAll
  • Restrict listeners (and requests) for elements that do not have a data-var-* attribute

See the design doc above for details.

Motivation

In amp-analytics, it is hard for publishers to track the visibility of elements that share selectors. Our current implementation only allows a one-to-one mapping between a single element and visibility trigger. This presents a challenge for publishers who would like to track the visibility of all similar elements, such as all amp-ads or all paragraphs in an article.

Hello! We've been following this issue, and are very excited for these changes to improve our impression analytics logic (and have tried it locally in development). Is there a known timeline for when the experiment flag will be removed (for the querySelectorAll portion)? Thanks.

Hi @enderton, have you used this feature with the experiment flag on?

Yes - in local and staged environments, yes (via toggling in dev tools AMP.toggleExperiment('visibility-trigger-improvements').

Is not yet in production code served by AMP CDN, so have not used https://amp.dev/documentation/guides-and-tutorials/learn/experimental/#served-from-cdn.ampproject.org.

It's our understanding that we could not enable this experiment for all users, so have held off making part of production code.
