HTML | DOM button Object
The button object in HTML is used to represent a <button> element. The getElementById() method is used to get the button object.

<!DOCTYPE html> <html> <head> <title> DOM Button Object </title> <!-- script to create new button --> <script> function Geeks() { var myDiv = document.getElementById("GFG"); // creating button element var button = document.createElement('BUTTON'); // creating text to be //displayed on button var text = document.createTextNode("Button"); // appending text to button button.appendChild(text); // appending button to div myDiv.appendChild(button); ; } </script> </head> <body style = "text-align: center;"> <h1 style = "color:green;"> GeeksforGeeks </h1> <h2> DOM Button Property </h2> <p>Click the button to create a button.</p> <button onclick = "Geeks()"> Press me! </button> <br><br> <div id = "GFG"></div> </body> </html> |
