{{DomRef}}
The HTMLButtonElement
interface provides properties and methods (beyond the {{HTMLElement("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, {{domxref("HTMLElement")}}.
Name | Type | Description |
---|---|---|
accessKey |
{{domxref("DOMString")}} | A single-character keyboard key to give access to the button. |
autofocus |
{{domxref("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 |
{{domxref("Boolean")}} | The control is disabled, meaning that it does not accept any clicks. |
form {{readonlyInline}} |
{{domxref("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 |
{{domxref("DOMString")}} | The URI of a resource that processes information submitted by the button. If specified, this attribute overrides the {{htmlattrxref("action", "form")}} attribute of the {{HTMLElement("form")}} element that owns this element. |
formEncType |
{{domxref("DOMString")}} | The type of content that is used to submit the form to the server. If specified, this attribute overrides the {{htmlattrxref("enctype", "form")}} attribute of the {{HTMLElement("form")}} element that owns this element. |
formMethod |
{{domxref("DOMString")}} | The HTTP method that the browser uses to submit the form. If specified, this attribute overrides the {{htmlattrxref("method", "form")}} attribute of the {{HTMLElement("form")}} element that owns this element. |
formNoValidate |
{{domxref("Boolean")}} | Indicates that the form is not to be validated when it is submitted. If specified, this attribute overrides the {{htmlattrxref("enctype", "form")}} attribute of the {{HTMLElement("form")}} element that owns this element. |
formTarget |
{{domxref("DOMString")}} | A name or keyword indicating where to display the response that is received after submitting the form. If specified, this attribute overrides the {{htmlattrxref("target", "form")}} attribute of the {{HTMLElement("form")}} element that owns this element. |
labels {{readonlyInline}} |
{{domxref("NodeList")}} | A list of {{HTMLElement("label")}} elements that are labels for this button. |
menu {{experimental_inline}} |
{{domxref("HTMLMenuElement")}} | The menu element to be displayed if the button is clicked and is of type="menu" . |
name |
{{domxref("DOMString")}} | The name of the object when submitted with a form. {{HTMLVersionInline(5)}} If specified, it must not be the empty string. |
tabIndex |
long | Number that represents this element's position in the tabbing order. |
type |
{{domxref("DOMString")}} | Indicates the behavior of the button. This is an enumerated attribute with the following possible values:
|
validationMessage {{readonlyInline}} |
{{domxref("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 {{readonlyInline}} |
{{domxref("ValidityState")}} | The validity states that this button is in. |
value |
{{domxref("DOMString")}} | The current form control value of the button. |
willValidate |
{{domxref("Boolean")}} | Indicates whether the button is a candidate for constraint validation. It is false if any conditions bar it from constraint validation. |
Methods
Inherits methods from its parent, {{domxref("HTMLElement")}}.
Name | Return Type | Description |
---|---|---|
checkValidity() |
{{domxref("Boolean")}} | Not supported for button elements. |
setCustomValidity(in DOMString error) |
void |
Not supported for button elements. |
WIth Gecko-based browser, use the {{cssxref(":-moz-submit-invalid")}} pseudo-class to style submit buttons based on the validation of a form.
