Instance properties

Inherits properties from its parent, {{domxref("HTMLElement")}}.

• {{domxref("HTMLButtonElement.command")}}

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

• {{domxref("HTMLButtonElement.commandForElement")}}

  • : A reference to an existing {{domxref("Element")}} that the button controls.

• {{domxref("HTMLButtonElement.disabled")}}

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

• {{domxref("HTMLButtonElement.form")}} {{ReadOnlyInline}}

  • : An {{domxref("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.

• {{domxref("HTMLButtonElement.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 {{HTMLElement("form")}} element that owns this element.

• {{domxref("HTMLButtonElement.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 {{HTMLElement("form")}} element that owns this element.

• {{domxref("HTMLButtonElement.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 {{HTMLElement("form")}} element that owns this element.

• {{domxref("HTMLButtonElement.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 {{HTMLElement("form")}} element that owns this element.

• {{domxref("HTMLButtonElement.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 {{HTMLElement("form")}} element that owns this element.

• {{domxref("HTMLButtonElement.interestForElement")}} {{experimental_inline}} {{non-standard_inline}}

  • : Gets or sets the target element of an interest invoker, in cases where the associated {{htmlelement("button")}} element is specified as an interest invoker.

• {{domxref("HTMLButtonElement.labels")}} {{ReadOnlyInline}}

  • : A {{domxref("NodeList")}} that represents a list of {{HTMLElement("label")}} elements that are labels for this button.

• {{domxref("HTMLButtonElement.name")}}

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

• {{domxref("HTMLButtonElement.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.

• {{domxref("HTMLButtonElement.popoverTargetElement")}}

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

• {{domxref("HTMLButtonElement.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_inline}}

• {{domxref("HTMLButtonElement.willValidate")}} {{ReadOnlyInline}}

  • : 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 {{HTMLElement("datalist")}} ancestor; or the disabled property is set to true.

• {{domxref("HTMLButtonElement.validationMessage")}} {{ReadOnlyInline}}

  • : 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.

• {{domxref("HTMLButtonElement.validity")}} {{ReadOnlyInline}}

  • : A {{domxref("ValidityState")}} representing the validity states that this button is in.

• {{domxref("HTMLButtonElement.value")}}

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

Instance methods

Inherits methods from its parent, {{domxref("HTMLElement")}}.

• {{domxref("HTMLButtonElement.checkValidity()")}}
  • : Returns true if the element's value has no validity problems; otherwise, returns false.
• {{domxref("HTMLButtonElement.reportValidity()")}}
  • : Performs the same action as checkValidity(), but also reports the result to the user if the invalid event was not canceled.
• {{domxref("HTMLButtonElement.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.
