Pay*_*teR 4 javascript iframe ads google-dfp double-click-advertising
我正在搜索解决方案,可以从Google DFP中的自定义广告素材中扩展SafeFrame自定义广告,这有可能吗？
有两种可能的解决方案:
1)使用 SafeFrame API
优点:
缺点:
2)使用window.postMessage()javascript方法编写自己的API代码
缺点:
优点:
SafeFrame API这个API易于使用,您可以在GPT Safeframe预览工具中看到一些示例 .
首先,您需要更新<head>网站中的DFP初始化脚本
var pageConfig = {
allowOverlayExpansion: true,
allowPushExpansion: true,
sandbox: true
};
googletag.pubads().setSafeFrameConfig(pageConfig);
这样可以在您的网站上展开SafeFrame广告.有关此内容的更多信息,请 参阅通过GPT控制SafeFrame Container行为.
现在,您可以创建自定义广告素材并在网站上将其作为SafeFrame投放.这是我的一个例子.这个例子可以"等待"util它可见,然后将扩展到<div id="container">SafeFrame内部的高度:
<div id="container">
some lines to make container height<br>
line<br>
line<br>
line<br>
line<br>
line<br>
line<br>
line<br>
line<br>
line<br>
line<br>
line<br>
line<br>
line<br>
line<br>
line<br>
line<br>
line<br>
</div>
<script>
// global expanded indicator variable, because API don't have any
var expanded = false;
function expand() {
var self= $sf.ext.geom().self;
var config = {
push: true, // we want to push expanded content
b: 0
};
var el = document.getElementById('container');
var containerHeight = el.offsetHeight;
// get height from bottom, that need to be expanded
var expandBottom = containerHeight - self.h;
// if container is whole inside a SafeFrame, it will not expand
if(expandBottom < 0) return;
config.b = expandBottom;
$sf.ext.expand(config);
}
function expandDelayed(forceExpand) {
// expand will run just once, or you can force it to run again
// but collapse first is needed
if(expanded && forceExpand || !expanded) {
$sf.ext.collapse();
expanded = false;
// there must be some timeout, because .collapse(); method is deplayed somehow
setTimeout(expand, 0);
}
}
$sf.ext.register(160, 150, function(status, data) {
// this code will do whole magic of "waiting" for right moment
if (status === 'geom-update') {
expandDelayed();
}
// change global expanded status
if (status === 'expanded') {
expanded = true;
}
});
// init
expandDelayed();
</script>
window.postMessage()javascript方法编写自己的API代码首先,您需要将此代码放入<head>您网站的DFP初始化脚本中.此代码将添加广告位的ID作为#hash-tag对<iframe>的SRC,所以你可以从你的创造性内得到它.
googletag.pubads().addEventListener('slotRenderEnded', function (event) {
var containerId = event.slot.getSlotElementId();
var containerEl = document.getElementById(containerId);
if (containerEl === null) return;
var iframeEl = containerEl.querySelectorAll('iframe')[0];
// it's delayed by 10 milliseconds, because iframe is not yet fully rendered
// and limited to max to 10 seconds to wait
var timeoutFunction = function () {
var src = "#" + containerId;
// `src` attribute is null, when iframe is FriendlyIframe, and
// when it's present, then it's SafeFrame
if (iframeEl.getAttribute('src') !== null) {
src = iframeEl.getAttribute('src').replace(/#.*/, "") + src;
} else {
var name = iframeEl.getAttribute('name') + "#" + containerId;
iframeEl.setAttribute('name', name);
}
iframeEl.setAttribute('src', src);
};
setTimeout(timeoutFunction, 10);
});
其次,您需要将此代码添加到您的网站,最好将其作为单独的.js文件添加.
function onMessageReceivedGetStyle(e) {
// this will filter just setStyle commands from correct origin
if (
!(e.origin === 'http://tpc.googlesyndication.com' || e.origin === 'https://tpc.googlesyndication.com') ||
typeof e.data !== 'object' ||
typeof e.data.id !== 'string' ||
e.data.cmd !== 'setStyle' ||
typeof e.data.params !== 'object'
) {
return;
}
// remove # character from id, we don't use jquery
var elementId = e.data.id.replace(/#/, "");
var wrapperEl = document.getElementById(elementId);
if (wrapperEl === null) {
return;
}
var elements = [wrapperEl];
// you can target child elements too with query parameter
if (typeof e.data.query === 'string' && e.data.query) {
elements = wrapperEl.querySelectorAll(e.data.query);
}
elements.forEach(function (element) {
Object.keys(e.data.params).forEach(function (param) {
element.style[param] = e.data.params[param];
});
});
}
if (window.addEventListener) {
addEventListener('message', onMessageReceivedGetStyle, false);
}
else {
if (window.attachEvent) {
attachEvent('onmessage', onMessageReceivedGetStyle);
}
else {
window.onmessage = onMessageReceivedGetStyle;
}
}
第三件事是DFP广告管理系统中自定义广告素材类型中的自定义代码.这是一个示例,与第一个示例中的示例类似,但此处此脚本可以等到所有内容和图像都加载完毕,然后使用creative扩展/缩小iframe:
<div id="container">
<a href="#" target="_blank">
<img src="%%FILE:JPG1%%">
</a>
<a href="#" target="_blank">
<img src="%%FILE:JPG2%%">
</a>
</div>
<style>
a {
display: block;
margin-bottom: .5em;
}
img {
display: block;
max-width: 100%;
}
*:last-child {
margin-bottom: 0;
}
</style>
<script>
var container = document.getElementById('container');
function resizeOutsideSafeFrame() {
if (!window.top.postMessage) {
return false;
}
// get ID of your Ad unit <div> with this creative
var divGptAdId = '%%PATTERN:url%%';
if (divGptAdId.indexOf('#') !== -1) {
divGptAdId = divGptAdId.split('#')[1];
} else {
divGptAdId = window.location.hash;
}
if(!divGptAdId) {
if (window.name.indexOf('#') !== -1) {
divGptAdId = window.name.split('#')[1];
}
}
if(!divGptAdId) {
return;
}
// set with to fullwidth, and height to height of container inside creative
var width = '100%';
var height = container.offsetHeight + 'px';
// send our request to website
window.top.postMessage({
cmd: 'setStyle',
id: divGptAdId,
query: 'div, iframe', // we want to target child div and iframe and don't change container styles
params: {
display: 'block',
height: height,
width: width
}
}, '*');
}
document.onreadystatechange = function () {
// resize iframe when all is loaded
if (document.readyState == "complete") {
resizeOutsideSafeFrame();
}
};
// first resize must occur little bit later
setTimeout(resizeOutsideSafeFrame, 100);
</script>
就这样.如果您想从iframe内部更改网站上的任何内容,您可以在网站上编写自己的cmd代码,并从iframe内部调用此命令.
编辑1:刚刚注意到,它var divGptAdId = '%%PATTERN:url%%;不会以#hash方式在页面上返回div的正确id,所以现在需要给他一个正确的容器div id更改:
if(!divGptAdId) {
return;
}
至
if(!divGptAdId) {
divGptAdId = 'div-gpt-ad-container-div-id-1';
}
