在页面部分加载脚本:
// set global variable if not already set
var googletag = googletag || {};
googletag.cmd = googletag.cmd || [];
// load asynchronously the GPT JavaScript library used by DFP,
// using SSL/HTTPS if necessary
(function() {
var gads = document.createElement('script');
gads.async = true;
gads.type = 'text/javascript';
var useSSL = 'https:' === document.location.protocol;
gads.src = (useSSL ? 'https:' : 'http:') + '//www.googletagservices.com/tag/js/gpt.js';
var node =document.getElementsByTagName('script')[0];
node.parentNode.insertBefore(gads, node);
})();
使用以下脚本初始化 google 发布者标签,最好在您页面的部分中:
// can be moved as well in the body
// if using async mode, wrap all the javascript into googletag.cmd.push!
googletag.cmd.push(function() {
// set page-level attributes for ad slots that serve AdSense
googletag.pubads().set("adsense_background_color", "FFFFFF");
googletag.pubads().setTargeting("topic","basketball");
// enables Single Request Architecture (SRA)
googletag.pubads().enableSingleRequest();
// Disable initial load, we will use refresh() to fetch ads.
// Calling this function means that display() calls just
// register the slot as ready, but do not fetch ads for it.
googletag.pubads().disableInitialLoad();
// Collapses empty div elements on a page when there is no ad content to display.
googletag.pubads().collapseEmptyDivs();
// Enables all GPT services that have been defined for ad slots on the page.
googletag.enableServices();
});
单独注册插槽(可以使用 foreach 循环生成)并渲染它们。事件侦听器也可以按插槽注册。
这里是重要的部分:确保一起刷新它们以避免在两个插槽上出现相同的广告(如果广告分配给两个插槽)=> googletag.pubads().refresh([slot1, slot2]]) ;
// this code can be moved externally to improve performance
googletag.cmd.push(function() {
// define slot1
slot1 = googletag.defineSlot(
"/1234/travel/asia/food",
[728, 90],
"banner1"
)
.addService(googletag.pubads())
.setTargeting(
"interests",
["sports", "music", "movies"]
);
// prerender the slot but don't display it because of disableInitialLoad()
googletag.display("banner1");
// define slot2
slot2 = googletag.defineSlot(
"/1234/travel/asia/food",
[[468, 60], [728, 90], [300, 250]],
"banner2"
)
.addService(googletag.pubads())
.setTargeting("gender", "male")
.setTargeting("age", "20-30");
// prerender the slot but don't display it because of disableInitialLoad()
googletag.display("banner2");
// add event to sign the slot as redered or not
googletag.pubads().addEventListener('slotRenderEnded', function(event) {
if (event.slot === slot1 || event.slot === slot2) {
// do something related to the slot
}
});
// refresh all container ads and show them
// very important to call refresh with an array to avoid
// multiple callback to the registered event
googletag.pubads().refresh([slot1, slot2]);
});
<div id="banner1" style="width:300px; height:250px;"></div>
<div id="banner2" style="width:300px; height:250px;"></div>
广告呈现后,回调被触发。
