    HTMLButtonElement

    The HTMLButtonElement interface provides properties and methods (beyond the <button> object interface it also has available to them by inheritance) for manipulating the layout and presentation of button elements.

    Properties

    Inherits properties from its parent, HTMLElement.

    Name Type Description
    accessKey DOMString A single-character keyboard key to give access to the button.
    autofocus Boolean The control should have input focus when the page loads, unless the user overrides it, for example by typing in a different control. Only one form-associated element in a document can have this attribute specified.
    disabled Boolean The control is disabled, meaning that it does not accept any clicks.
    form Read only HTMLFormElement The form that this button is associated with. If the button is a descendant of a form element, then this attribute is the ID of that form element.
    If the button is not a descendant of a form element, then the attribute can be the ID of any form element in the same document it is related to, or the null value if none matches.
    formAction DOMString The URI of a resource that processes information submitted by the button. If specified, this attribute overrides the action attribute of the <form> element that owns this element.
    formEncType DOMString The type of content that is used to submit the form to the server. If specified, this attribute overrides the enctype attribute of the <form> element that owns this element.
    formMethod DOMString The HTTP method that the browser uses to submit the form. If specified, this attribute overrides the method attribute of the <form> element that owns this element.
    formNoValidate Boolean Indicates that the form is not to be validated when it is submitted. If specified, this attribute overrides the novalidate attribute of the <form> element that owns this element.
    formTarget DOMString A name or keyword indicating where to display the response that is received after submitting the form. If specified, this attribute overrides the target attribute of the <form> element that owns this element.
    labels Read only NodeList A list of <label> elements that are labels for this button.
    menu  HTMLMenuElement The menu element to be displayed if the button is clicked and is of type="menu".
    name DOMString The name of the object when submitted with a form. HTML5 If specified, it must not be the empty string.
    tabIndex long Number that represents this element's position in the tabbing order.
    type DOMString Indicates the behavior of the button. This is an enumerated attribute with the following possible values:
    • "submit": The button submits the form. This is the default value if the attribute is not specified, HTML5 or if it is dynamically changed to an empty or invalid value.
    • "reset": The button resets the form.
    • "button": The button does nothing.
    • "menu": The button displays a menu.
    validationMessage Read only DOMString A localized message that describes the validation constraints that the control does not satisfy (if any). This attribute is the empty string if the control is not a candidate for constraint validation (willValidate is false), or it satisfies its constraints.
    validity Read only ValidityState The validity states that this button is in.
    value DOMString The current form control value of the button.
    willValidate Boolean Indicates whether the button is a candidate for constraint validation. It is false if any conditions bar it from constraint validation.
