Attributes

Includes the Global Attributes.

NameVersionDescription
formaction HTML5 The URI of a program that processes the information submitted by the input element, here image if specified, it overrides the action attribute of the element's form owner.
formenctype HTML5 If the input element is an image, this attribute specifies the type of content that is used to submit the form to the server. Possible values are:
  • application/x-www-form-urlencoded: The default value if the attribute is not specified.
  • multipart/form-data: Use this value if you are using an <input> element with the type attribute set to file.
  • text/plain

If this attribute is specified, it overrides the enctype attribute of the element's form owner.
formmethod HTML5 In image input element, this attribute specifies the HTTP method that the browser uses to submit the form. Possible values are:
  • post: The data from the form is included in the body of the form and is sent to the server.
  • get: The data from the form is appended to the form attribute URI, with a '?' as a separator, and the resulting URI is sent to the server. Use this method when the form has no side-effects and contains only ASCII characters.

If specified, this attribute overrides the method attribute of the element's form owner.
formnovalidate HTML5 This Boolean attribute specifies that the form is not to be validated when it is submitted. If this attribute is specified, it overrides the novalidate attribute of the element's form owner.
formtarget HTML5 This attribute is a name or keyword indicating where to display the response that is received after submitting the form. This is a name of, or keyword for, a browsing context (for example, tab, window, or inline frame). If this attribute is specified, it overrides the target attribute of the element's form owner. The following keywords have special meanings:
  • _self: Load the response into the same browsing context as the current one. This value is the default if the attribute is not specified.
  • _blank: Load the response into a new unnamed browsing context.
  • _parent: Load the response into the parent browsing context of the current one. If there is no parent, this option behaves the same way as _self.
  • _top: Load the response into the top-level browsing context (that is, the browsing context that is an ancestor of the current one, and has no parent). If there is no parent, this option behaves the same way as _self.
height HTML5 This attribute defines the height of the image displayed for the button.
