How Can a Button Prevent Unintentional Form Submission?

Can a Avoid Submitting a Form?

When using buttons in a form, it's common to encounter an issue where the "Cancel changes" button unintentionally submits the form. To address this, jQuery UI's button widget can be used to style the buttons. However, by default, all button elements act as submit buttons in a form.

To prevent the Cancel button from triggering form submission, it's crucial to specify the type attribute as "button":

<button type="button">Cancel changes</button>

This will instruct the browser that this button is intended for actions other than form submission, such as modal dialogs or custom event handling.

As mentioned in the HTML Standard, a button element with type="button" performs no specific action. It's primarily used for controlling custom behavior using event handlers, making it ideal for cancel buttons or other non-submitting actions within a form.
