我们在使用Google Doubleclick时遇到了一些难以理解的问题
横幅不断展现和消失。
调试告诉我们这个：
gpt.js：49无法在'Document'上执行'write'：除非明确打开，否则无法从异步加载的外部脚本写入文档。
我们在php中分别调用代码，因为Wordpress和LOLS
有了这个函数，我们称之为主JS
function googletag(){
$googletag = "
var googletag = googletag || {};
googletag.cmd = googletag.cmd || [];
(function(){
//console.log('Failed to display 3rd party ad, displaying google ad instead');
var gads = document.createElement('script');
gads.async = true;
gads.type = 'text/javascript';
var useSSL = 'https:' == document.location.protocol;
gads.src = (useSSL ? 'https:' : 'http:') + '//www.googletagservices.com/tag/js/gpt.js';
var node = document.getElementsByTagName('script')[0];
node.parentNode.insertBefore(gads, node);
})();
";
echo "\n<script>\n/* <![CDATA[ */$googletag\n/* ]]> */\n</script>\n";
}
然后是DFP元素：
<?php
function doubleclick(){
global $post;
$url = get_template_directory_uri();
$doubleclick = '';
if(is_category('11142')) {
$doubleclick .="<script src=\"$url/js/double/slot-allaccess.js\" type=\"text/javascript\" charset=\"utf-8\"></script>";
} elseif(is_category('363')) {
$doubleclick .="<script src=\"$url/js/double/slot-artroom.js\" type=\"text/javascript\" charset=\"utf-8\"></script>";
} elseif(is_category('11098')) {

} elseif(is_category('360')) {

} elseif(is_category('11096')) {
$doubleclick .="<script src=\"$url/js/double/slot-cookbook.js\" type=\"text/javascript\" charset=\"utf-8\"></script>";

} elseif(is_category('349')) {
$doubleclick .="<script src=\"$url/js/double/slot-jewels.js\" type=\"text/javascript\" charset=\"utf-8\"></script>";
} elseif(is_category('17')) {
$doubleclick .="<script src=\"$url/js/double/slot-listen.js\" type=\"text/javascript\" charset=\"utf-8\"></script>";
} elseif(is_category('364')) {

} elseif(is_category('11097')) {

} elseif(is_category('356')) {

} elseif(is_category('11143')) {
$doubleclick .="<script src=\"$url/js/double/slot-redcarpet.js\" type=\"text/javascript\" charset=\"utf-8\"></script>";
} elseif(is_category('369')) {
$doubleclick .="<script src=\"$url/js/double/slot-scents.js\" type=\"text/javascript\" charset=\"utf-8\"></script>";
} elseif(is_category('15')) {
$doubleclick .="<script src=\"$url/js/double/slot-see.js\" type=\"text/javascript\" charset=\"utf-8\"></script>";
} elseif(is_category('13')) {
$doubleclick .="<script src=\"$url/js/double/slot-smell.js\" type=\"text/javascript\" charset=\"utf-8\"></script>";
} elseif(is_category('368')) {
$doubleclick .="<script src=\"$url/js/double/slot-spa.js\" type=\"text/javascript\" charset=\"utf-8\"></script>";
} elseif(is_category('355')) {
$doubleclick .="<script src=\"$url/js/double/slot-spotted.js\" type=\"text/javascript\" charset=\"utf-8\"></script>";
} elseif(is_category('16')) {
$doubleclick .="<script src=\"$url/js/double/slot-taste.js\" type=\"text/javascript\" charset=\"utf-8\"></script>";
} elseif(is_category('350')) {
$doubleclick .="<script src=\"$url/js/double/slot-tech.js\" type=\"text/javascript\" charset=\"utf-8\"></script>";
} elseif(is_category('352')) {
$doubleclick .="<script src=\"$url/js/double/slot-timekeepers.js\" type=\"text/javascript\" charset=\"utf-8\"></script>";
} elseif(is_category('14')) {
$doubleclick .="<script src=\"$url/js/double/slot-touch.js\" type=\"text/javascript\" charset=\"utf-8\"></script>";
} elseif(is_category('351')) {
$doubleclick .="<script src=\"$url/js/double/slot-toysfb.js\" type=\"text/javascript\" charset=\"utf-8\"></script>";
} elseif(is_category('353')) {
$doubleclick .="<script src=\"$url/js/double/slot-traveling.js\" type=\"text/javascript\" charset=\"utf-8\"></script>";
} elseif(is_category('367')) {
$doubleclick .="<script src=\"$url/js/double/slot-wellness.js\" type=\"text/javascript\" charset=\"utf-8\"></script>";
} else {
$doubleclick .="<script src=\"$url/js/double/slot-notas.js\" type=\"text/javascript\" charset=\"utf-8\"></script>";
}
if(!empty($doubleclick)) {
$doubleclick = "\n<!-- Doubleclick Tag Script -->\n" . $doubleclick . "\n";
echo $doubleclick;
}
}
?>
然后我们放置其中一个横幅：
function top_banner(){
if ( is_home() || is_front_page()) {
echo "<!-- home_960x90a -->";
echo "<div id=\"div-gpt-ad-1427326520458-38\" style=\"width:728px; height:90px;margin:0 auto;\">\n";
echo "<script>\n/* <![CDATA[ */\n";
echo "googletag.cmd.push(function() { googletag.display('div-gpt-ad-1427326520458-38'); });\n";
echo "/* ]]> */\n</script>\n";
echo "</div>\n";
}
但是没有任何工作，或者有时工作正常。
您尝试加载的标记显然正在使用使用document.write的广告系列，并且它们是异步加载的。您应该将广告系列（您或您的提供商）迁移到异步解决方案或同步加载标记：https://support.google.com/dfp_premium/answer/1638622
