এজন্য document.querySelectorAll() এবং getElementsByClassName() ব্যবহার করুন।
উদাহরণ
<!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> ফাইল সেভ করুন "index.html" নামে এবং VS Code-এ "Open with Live Server" দিয়ে রান করুন।
