javascript - 通过 JavaScript 在 ins 标签内更改值

Question

<ins class='adsbygoogle'
style='display:block'
data-ad-client='ca-pub-XXXXXXXXXXXXXXX'
data-ad-slot='000000000000'
data-ad-format='auto'
data-full-width-responsive='true'></ins>

我想用 JavaScript 将 data-ad-slot 值更改为 123456789。我怎样才能做到这一点？
我试过这个~(但不工作)

<ins class='adsbygoogle'
    style='display:block'
    data-ad-client='ca-pub-XXXXXXXXXXXXXXX'
    data-ad-slot=document.write (x);
    data-ad-format='auto'
    data-full-width-responsive='true'></ins>

    <script> var x= 123456789;</script>

Answer 1

设置 .dataset.adSlot 。

<ins class='adsbygoogle'
    style='display:block'
    data-ad-client='ca-pub-XXXXXXXXXXXXXXX'
    data-ad-format='auto'
    data-full-width-responsive='true'></ins>
<script> 
var x= 123456789;
var elem = document.querySelector('.adsbygoogle');
elem.dataset.adSlot = x;
console.log(elem);
</script>
