我正在尝试将新引入的googletag.PubAdsService.enableLazyLoad选项与 DFP 广告一起使用。它在初始页面加载期间工作正常，但是当我尝试刷新页面上的广告时，我收到以下错误：
排队的 GPT 命令类型错误中的异常：无法在 Wt（pubads_impl_242.js: 1) at pubads_impl_242.js:1 at Vt (pubads_impl_242.js:1) at _.V.$a (pubads_impl_242.js:1) at Xu (pubads_impl_242.js:1) at Cv (pubads_impl_242.js:1) at 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});
});
