为此，请使用 document.querySelectorAll()。同时，还使用 getElementsByClassName()。以下是代码 −

示例

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initialscale=1.0">
<title>Document</title>
<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
</head>
<body>
<h2 class="uniqueId"> My Name is John </h6>
<div class="my-main-div-class">
<div class="div-class-2">
<span>My h6 value must be here...</span>
</div>
<div class="div-class-end">
<span>My h6 value must be here...</span>
<span>My h6 value must be here...</span>
</div>
</div>
<script>
   const allSpan = document.querySelectorAll('.my-main-div-class span'),
   repaceAboveText =
   document.getElementsByClassName('uniqueId')[0].textContent;
   for (var newElement of allSpan){
      newElement.textContent=repaceAboveText
   }
</script>
</body>
</html>

要运行上述程序，请保存文件名"anyName.html(index.html)"，然后右键单击该文件。在 VS Code 编辑器中选择选项"使用 Live Server 打开"。
