Detailed Description

Adds a generic button inline to the form.

Does not do anything, you must add click handling code in JavaScript. Use a HTMLSubmitField if you merely wish to add a submit button to a form.

Additional recognized configuration parameters include:

• flags: OOUI flags for the button, see OOUI\FlaggedElement
• buttonlabel-message: Message to use for the button display text, instead of the value from 'default'. Overrides 'buttonlabel' and 'buttonlabel-raw'.
• buttonlabel: Text to display for the button display text, instead of the value from 'default'. Overrides 'buttonlabel-raw'.
• buttonlabel-raw: HTMLto display for the button display text, instead of the value from 'default'.
• formnovalidate: Set to true if clicking this button should suppress client-side form validation. Used in HTMLFormFieldCloner for add/remove buttons.
