In the previous tutorial in this series, “How To Make Changes to the DOM,” we covered how to create, insert, replace, and remove elements from the Document Object Model (DOM) with built-in methods. By increasing your proficiency in manipulating the DOM, you are better able to utilize JavaScript’s interactive capabilities and modify web elements.
In this tutorial, you will learn how to further alter the DOM by modifying styles, classes, and other attributes of HTML element nodes. This will give you a greater understanding of how to manipulate essential elements within the DOM.
Thanks for learning with the DigitalOcean Community. Check out our offerings for compute, storage, networking, and managed databases.
The Document Object Model, usually referred to as the DOM, is an essential part of making websites interactive. It is an interface that allows a programming language to manipulate the content, structure, and style of a website. JavaScript is the client-side scripting language that connects to the DOM in an internet browser.

Great Article, very useful…
Ideally, you should also include:- removeProperty
This would help with one requirement that you’ve missed.
Thanks for this Tutorial: I am hoping you can tell me why this statement doesn’t work ? intoCount[0].innerHtml = copyFromVar; [code] <!DOCTYPE html> <html> <body> <h5>Copy-Text-from-textarea-to-div.html</h5> Field1: <input type=“text” id=“field1” value=“Hello from Field1 !”><br> Field2: <input type=“text” id=“field2”><br><br>
<button onclick=“myFunction()”>Copy text From field1 to field2</button> <button onclick=“saveItAll()”>Copy text From textarea to contentEditable-div</button>
<br><br> <textarea class=“copyFrom” rows=“4” cols=“20”>TextArea1 </textarea> <br> <textarea class=“copyFrom” rows=“4” cols=“20” >TextArea2 </textarea> <br> <div class=“pasteInto” contentEditable=“false” >pasteInto 1</div> <div class=“pasteInto” contentEditable=“true” >pasteInto 2</div>
<p>A function is triggered when the button is clicked. The function copies the text from Field1 into Field2.</p> <script> var copyFromVar = “”; var fromCount; // = document.getElementsByClassName(“copyFrom”); var intoCount; // = document.getElementsByClassName(“pasteInto”); function saveItAll() { fromCount = document.getElementsByClassName(“copyFrom”); intoCount = document.getElementsByClassName(“pasteInto”);
copyFromVar = fromCount[0].value ; intoCount[0].innerHtml = copyFromVar; alert("0 copyFromVar = " + copyFromVar );
copyFromVar = fromCount[1].value ; intoCount[1].innerHtml = copyFromVar; alert("1 copyFromVar = " + copyFromVar );
} </script> <script> function myFunction() { document.getElementById(“field2”).value = document.getElementById(“field1”).value; } </script>
</body> </html>
[/code] Thanks
