javascript - 脚本标签内的异步脚本 src，GDPR 合规性谷歌广告

Question

我正在进行 GDPR cookie 合规性检查，并尝试仅在用户接受 cookie 时加载 Google 广告。

我只想在 cookie 不存在时加载谷歌广告脚本。所以我想这样做:

    <script>
    if(cookieNo!="1"){
       <script async src="https://www.googletagmanager.com/gtag/js?id=AW-mycode"></script>
       window.dataLayer = window.dataLayer || [];
       function gtag(){dataLayer.push(arguments);}
       gtag('js', new Date());

       gtag('config', 'AW-mycode');
       }
     <script>

知道如何将脚本标签放在脚本标签内吗？

Answer 1

下面是一个片段，您可以使用它向网页添加异步脚本。将其包装在您的条件中，您就可以开始了。

const gScript = document.createElement('script');
gScript.src = "https://www.googletagmanager.com/gtag/js?id=AW-mycode";
gScript.type = 'text/javascript';
gScript.onload = () => {
   console.log('Script has been fully loaded');
  // initlaize anything you want that needs to be done after script has loaded
  // Below code in your case
   window.dataLayer = window.dataLayer || [];
   function gtag(){dataLayer.push(arguments);}
   gtag('js', new Date());
   gtag('config', 'AW-mycode');

};
gScript.async = true;
gScript.charset = 'utf-8';
document.getElementsByTagName('head')[0].appendChild(gScript);

希望这有帮助:)
