HTMLOrForeignElement - Web APIs 编辑

Draft

This page is not complete.

The HTMLOrForeignElement mixin describes several features common to the HTMLElement, SVGElement and MathMLElement interfaces. Each of these interfaces can, of course, add more features in addition to the ones listed below.

Note: HTMLOrForeignElement is a mixin and not an interface; you can't actually create an object of type HTMLOrForeignElement.

Properties

dataset undefined

The dataset read-only property of the HTMLOrForeignElement interface provides read/write access to custom data attributes (data-*) on elements.

nonce

The nonce property of the HTMLOrForeignElement interface returns the cryptographic number used once that is used by Content Security Policy to determine whether a given fetch will be allowed to proceed.

tabIndex

The tabIndex property of the HTMLOrForeignElement interface represents the tab order of the current element.

Methods

blur()

The HTMLElement.blur() method removes keyboard focus from the current element.

focus()

The HTMLElement.focus() method sets focus on the specified element, if it can be focused. The focused element is the element which will receive keyboard and similar events by default.
