Typebutton

Typebutton refers to a button element in HTML that uses the type attribute with the value "button" (type="button"). Such a button does not have any built-in submission or reset behavior and is intended to be wired to custom actions via JavaScript or other event handlers.

In HTML, the button element supports three primary type values: "button", "submit", and "reset". A button with type="button" has no default action beyond its click event; this makes it suitable for triggering scripts, opening dialogs, or performing UI tasks without submitting a form. By contrast, a button with type="submit" submits the form it belongs to, and type="reset" resets form controls to their initial values. If the type attribute is omitted, the default is generally "submit" for buttons inside a form, which can cause unintended form submissions.

Usage examples can be simple or complex. A basic example is: <button type="button" onclick="doSomething()">Click me</button>. For accessibility and semantics, a button element is preferred over styling a non-button element to look like a button, as it provides proper keyboard and screen reader support. The button element also allows rich content inside it, such as images or icons, whereas input type="button" is limited to plain text.

In summary, type="button" is a standard HTML mechanism for creating an interactive button that performs actions via scripts rather than form submission, and it is distinct from the default submit behavior of buttons placed within forms.
