<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Document</title>
    <style>
        .box{
            width: 200px;
            height:200px;
            background-color: green;
        }
     </style> 
</head>
<body>
    <div class="val">我很好</div>
    <script>
        let val=document.getElementsByClassName('val');
        alert(val.innerHTML);
        var box = document.createElement('div');
        box.innerHTML=`<span>${val.innerText} </span>`;
        box.className='box';
        document.body.appendChild(box);
    </script>
</body>
</html>
