You can programmatically create a new body element using document.createElement() and assign the innerHTML of the active document.body to it.
let body = document.createElement('body');
body.innerHTML = document.body.innerHTML;
body.querySelectorAll('div').forEach(d => {
d.classList.add('red');
console.log(d)
});.red {
background-color:tomato;
}<body>
<div>
<button type='button'>Button</button>
</div>
</body>热门帖子
