我正在尝试将新引入的googletag.PubAdsService.enableLazyLoad选项用于DFP广告管理系统广告。在初始页面加载期间,它可以正常工作,但是当我尝试刷新页面上的广告时,出现以下错误:

  

排队的GPT命令TypeError中的异常:无法读取null的属性“ unobserve”       在Nt(pubads_impl_242.js:1)       在pubads_impl_242.js:1       在Object ._。y(pubads_impl_242.js:1)       在Wt(pubads_impl_242.js:1)       在pubads_impl_242.js:1       在Vt(pubads_impl_242.js:1)       在_.V。$ a(pubads_impl_242.js:1)       在徐(pubads_impl_242.js:1)       简历(pubads_impl_242.js:1)       在wv ._。h.refresh(pubads_impl_242.js:1)

这是我的代码:

var googletag = googletag || {};
googletag.cmd = googletag.cmd || [];
googletag.slots = googletag.slots || {};
var mapping = googletag.sizeMapping()
  .addSize([0, 0], [1000, 1])
  .addSize([320, 0], [[320, 50], [300, 50]])
  .addSize([1025, 0], [970, 90])
  .build();
googletag.slots["push"] = googletag.defineSlot("/1234/sample/", [[970, 90], [320, 50], [300, 50]], "dfp-ad-banner")
  .addService(googletag.pubads())
  .setTargeting("pos", "banner")
  .defineSizeMapping(mapping);
googletag.cmd.push(function() {
  googletag.pubads().enableAsyncRendering();
  googletag.pubads().collapseEmptyDivs();
  googletag.pubads().disableInitialLoad();
  googletag.pubads().enableLazyLoad({fetchMarginPercent: 200,renderMarginPercent: 100,mobileScaling: 2.0});
});
googletag.enableServices();
...
googletag.cmd.push(function() {
  googletag.display("dfp-ad-banner");
});
...
googletag.cmd.push(function () {
        // add visibility helper classes
        googletag.pubads().addEventListener('slotRenderEnded', function (event) {
          var adClass = (event.size[0] > 1 && event.size[1] > 1) ? 'ad-visible' : 'ad-invisible';
          $('#' + event.slot.getSlotElementId()).addClass(adClass);
        });
        // load ads
        googletag.pubads().refresh(null, {changeCorrelator: false});
      });

这是因为到目前为止collapseEmptyDivsenableLazyLoad不兼容。我建议删除collapseEmptyDivs

有关刷新和销毁的问题现在应该修复。如果将来遇到此类问题,请考虑从开发者参考页面发送反馈。 https://developers.google.com/doubleclick-gpt/reference
