HTML <button> Tag with the 'form' Attribute

<form id="myForm" action="/resources/html-forms-action.cfm">
<!-- ...form contents... -->
</form>	

<button form="myForm">
Submit Form
</button>

In the above example we add the form attribute to a button control. We also add the actual <form> element that the button is using.

About the form Attribute

The form attribute allows you to specify the ID of a form to which this control belongs. This allows you to use the <button> element without having to nest it within <form> tags.

If this attribute is used, its value must be the ID of a form element in the element's owner.

About the <button> Element

The <button> element creates a button control in an HTML document.

Any contents of the <button> element appears on the button.

The <button> element can be associated with a form or stand alone by itself (in such case it could have JavaScript attached via the onclick attribute) to make the button actually do something.
