做了个小站,申请的谷歌和百度的广告,
放到js文件中后,用document.write来写的,但是前台就是不出现,请帮忙看下是哪里出错了?

document.writeln("<\script src=\"//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>

<ins class="adsbygoogle"
style="display:inline-block;width:970px;height:250px"
data-ad-client="ca-pub-9055653551438880"
data-ad-slot="7443996645"></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script>");

var ga = document.createElement("script");
ga.src = "//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js";
document.getElementsByTagName("head")[0].appendChild(ga);

var ins = document.createElement("ins");
ins.className = "adsbygoogle";
ins.style = "display:inline-block;width:970px;height:250px";
ins.setAttribute("data-ad-client", "ca-pub-9055653551438880");
ins.setAttribute("data-ad-slot", "7443996645");
document.getElementsByTagName("body")[0].appendChild(ins);

(adsbygoogle = window.adsbygoogle || []).push({});

虽然不知道楼主为啥不直接写进HTML，但是楼主的写法太尼玛凶残了……

为啥要这样写，就算是 document.write ，也会堵塞页面的

document.write才对吧
另外浏览器检查 script标签内容的时候看到</script>会当做脚本定义完毕
参照 h5bp 的做法，字符串里应该用这个 <\/script>

async或者defer下吧

另外，小声的说下，楼主是不是忘了关adb？

这写法还是够奇葩
