HTMLButtonElement

The HTMLButtonElement interface provides properties and methods (beyond the regular HTMLElement interface it also has available to it by inheritance) for manipulating <button> elements.

Instance properties

Inherits properties from its parent, HTMLElement.

• command

  • : A string value indicating the action to be performed on an element being controlled by this button.

• commandForElement

  • : A reference to an existing Element that the button controls.

• disabled

  • : A boolean value indicating whether or not the control is disabled, meaning that it does not accept any clicks.

• form Read only

  • : An HTMLFormElement reflecting the form that this button is associated with. If the button is a descendant of a form element, then this attribute is a reference to that form’s associated HTMLFormElement. If the button is not a descendant of a form element, then the attribute can be a reference to any HTMLFormElement element in the same document it is related to, or the null value if none matches.

• formAction

  • : A string reflecting 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

  • : A string reflecting 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

  • : A string reflecting 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

  • : A boolean value indicating 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

  • : A string reflecting a name or keyword indicating where to display the response received after submitting the form. If specified, this attribute overrides the target attribute of the <form> element that owns this element.

• interestForElement Experimental

  • : Gets or sets the target element of an interest invoker, in cases where the associated <button> element is specified as an interest invoker.

• labels Read only

  • : A NodeList that represents a list of <label> elements that are labels for this button.

• name

  • : A string representing the object’s name when submitted with a form. If specified, it must not be the empty string.

• popoverTargetAction

  • : Gets and sets the action to be performed ("hide", "show", or "toggle") on a popover element being controlled by a control button. It reflects the value of the popovertargetaction HTML attribute.

• popoverTargetElement

  • : Gets and sets the popover element to control via a button. The JavaScript equivalent of the popovertarget HTML attribute.

• type

  • : A string indicating 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, 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. Experimental

• willValidate Read only

  • : A boolean value indicating whether the button is a candidate for constraint validation. It is false if any conditions bar it from constraint validation, including: its type property is reset or button; it has a <datalist> ancestor; or the disabled property is set to true.

• validationMessage Read only

  • : A string representing the 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

  • : A ValidityState representing the validity states that this button is in.

• value

  • : A string representing the current form control value of the button.

Instance methods

Inherits methods from its parent, HTMLElement.

• checkValidity()
  • : Returns true if the element’s value has no validity problems; otherwise, returns false.
• reportValidity()
  • : Performs the same action as checkValidity(), but also reports the result to the user if the invalid event was not canceled.
• setCustomValidity()
  • : Sets the custom validity message for the element. Use the empty string to indicate that the element does not have a custom validity error.
