The <button> HTML element is used to create interactive buttons on a webpage. It is a versatile element that can trigger various actions when clicked, such as submitting a form, resetting form data, or executing custom JavaScript functions. The <button> tag is a key component in creating interactive and dynamic user interfaces, allowing users to interact with web applications effectively.
The <button> element supports several attributes that define its behavior and appearance. The type attribute specifies the button's functionality, with possible values including submit, reset, and button. The submit type is used to submit form data to a server, the reset type clears all form fields, and the button type is used for custom actions defined by JavaScript. Additionally, the disabled attribute can be used to disable the button, preventing user interaction. Here is an example of how the <button> tag can be used:
<button type="button" onclick="alert('Button clicked!')">Click Me</button>Valid Attributes for <button>
| Attribute | Description |
