Submit button

A submit button is an element in HTML that can be used to submit a <form>. The native submit button elements are:

• <button> (its default type is "submit")
• <input type="submit">
• <input type="image">

In addition to submitting a form, a submit button can affect the form's behavior and what data is sent.

Overriding the form's behavior

Submit buttons can override the form's submission behavior through various attributes:

• formaction : Override the action attribute of the form.
• formenctype : Override the enctype attribute of the form.
• formmethod : Override the method attribute of the form.
• formnovalidate : Override the novalidate attribute of the form.
• formtarget : Override the target attribute of the form.

Form data entries

If the submit button is a <button> or <input type="submit"> and has a name attribute, the form data set will include an entry for its name and value.

If the submit button is an <input type="image"> , the form data set will include entries for the X and Y coordinates that the user clicked on (e.g., x=100&y=200 or buttonName.x=123&buttonName.y=234).
