    ngElementStrategy

    NgElementStrategy

    The strategy that controls how a component is transformed in a custom element.

    ngElementEventsSubscription

    any

    A subscription to change, connect, and disconnect events in the custom element.

    attributeChangedCallback

    void

    Prototype for a handler that responds to a change in an observed attribute.

    @paramattrNamestring

    The name of the attribute that has changed.

    @paramoldValuestring | null

    The previous value of the attribute.

    @paramnewValuestring

    The new value of the attribute.

    @paramnamespacestring | undefined

    The namespace in which the attribute is defined.

    @returnsvoid

    Nothing.

    connectedCallback

    void

    Prototype for a handler that responds to the insertion of the custom element in the DOM.

    @returnsvoid

    Nothing.

    disconnectedCallback

    void

    Prototype for a handler that responds to the deletion of the custom element from the DOM.

    @returnsvoid

    Nothing.

    accessKey

    string

    The HTMLElement.accessKey property sets the keystroke which a user can press to jump to a given element.

    MDN Reference

    accessKeyLabel

    string

    The HTMLElement.accessKeyLabel read-only property returns a string containing the element's browser-assigned access key (if any); otherwise it returns an empty string.

    MDN Reference

    autocapitalize

    string

    The autocapitalize property of the HTMLElement interface represents the element's capitalization behavior for user input. It is available on all HTML elements, though it doesn't affect all of them, including:

    MDN Reference

    autocorrect

    boolean

    The autocorrect property of the HTMLElement interface controls whether or not autocorrection of editable text is enabled for spelling and/or punctuation errors.

    MDN Reference

    dir

    string

    The HTMLElement.dir property indicates the text writing directionality of the content of the current element. It reflects the element's dir attribute.

    MDN Reference

    draggable

    boolean

    The draggable property of the HTMLElement interface gets and sets a Boolean primitive indicating if the element is draggable.

    MDN Reference

    hidden

    boolean | "until-found"

    The HTMLElement property hidden reflects the value of the element's hidden attribute.

    MDN Reference

    inert

    boolean

    The HTMLElement property inert reflects the value of the element's inert attribute. It is a boolean value that, when present, makes the browser "ignore" user input events for the element, including focus events and events from assistive technologies. The browser may also ignore page search and text selection in the element. This can be useful when building UIs such as modals where you would want to "trap" the focus inside the modal when it's visible.

    MDN Reference

    innerText

    string

    The innerText property of the HTMLElement interface represents the rendered text content of a node and its descendants.

    MDN Reference

    lang

    string

    The lang property of the HTMLElement interface indicates the base language of an element's attribute values and text content, in the form of a BCP 47 language tag. It reflects the element's lang attribute; the xml:lang attribute does not affect this property.

    MDN Reference

    offsetHeight

    number

    The offsetHeight read-only property of the HTMLElement interface returns the height of an element, including vertical padding and borders, as an integer.

    MDN Reference

    offsetLeft

    number

    The offsetLeft read-only property of the HTMLElement interface returns the number of pixels that the upper left corner of the current element is offset to the left within the HTMLElement.offsetParent node.

    MDN Reference

    offsetParent

    Element | null

    The HTMLElement.offsetParent read-only property returns a reference to the element which is the closest (nearest in the containment hierarchy) positioned ancestor element.

    MDN Reference

    offsetTop

    number

    The offsetTop read-only property of the HTMLElement interface returns the distance from the outer border of the current element (including its margin) to the top padding edge of the offsetParent, the closest positioned ancestor element.

    MDN Reference

    offsetWidth

    number

    The offsetWidth read-only property of the HTMLElement interface returns the layout width of an element as an integer.

    MDN Reference

    outerText

    string

    The outerText property of the HTMLElement interface returns the same value as HTMLElement.innerText. When used as a setter it replaces the whole current node with the given text (this differs from innerText, which replaces the content inside the current node).

    MDN Reference

    popover

    string | null

    The popover property of the HTMLElement interface gets and sets an element's popover state via JavaScript ("auto", "hint", or "manual"), and can be used for feature detection.

    MDN Reference

    spellcheck

    boolean

    The spellcheck property of the HTMLElement interface represents a boolean value that controls the spell-checking hint. It is available on all HTML elements, though it doesn't affect all of them.

    MDN Reference

    title

    string

    The HTMLElement.title property represents the title of the element: the text usually displayed in a 'tooltip' popup when the mouse is over the node.

    MDN Reference

    translate

    boolean

    The translate property of the HTMLElement interface indicates whether an element's attribute values and the values of its Text node children are to be translated when the page is localized, or whether to leave them unchanged.

    MDN Reference

    writingSuggestions

    string

    The writingSuggestions property of the HTMLElement interface is a string indicating if browser-provided writing suggestions should be enabled under the scope of the element or not.

    MDN Reference

    attachInternals

    ElementInternals

    The HTMLElement.attachInternals() method returns an ElementInternals object. This method allows a custom element to participate in HTML forms. The ElementInternals interface provides utilities for working with these elements in the same way you would work with any standard HTML form element, and also exposes the Accessibility Object Model to the element.

    MDN Reference

    @returnsElementInternals

    click

    void

    The HTMLElement.click() method simulates a mouse click on an element. When called on an element, the element's click event is fired (unless its disabled attribute is set).

    MDN Reference

    @returnsvoid

    hidePopover

    void

    The hidePopover() method of the HTMLElement interface hides a popover element (i.e., one that has a valid popover attribute) by removing it from the top layer and styling it with display: none.

    MDN Reference

    @returnsvoid

    showPopover

    void

    The showPopover() method of the HTMLElement interface shows a popover element (i.e., one that has a valid popover attribute) by adding it to the top layer.

    MDN Reference

    @paramoptionsShowPopoverOptions | undefined
    @returnsvoid

    togglePopover

    boolean

    The togglePopover() method of the HTMLElement interface toggles a popover element (i.e., one that has a valid popover attribute) between the hidden and showing states.

    MDN Reference

    @paramoptionsboolean | TogglePopoverOptions | undefined
    @returnsboolean

    @paramlistenerEventListenerOrEventListenerObject
    @paramoptionsboolean | EventListenerOptions | undefined
    @returnsvoid

    attributes

    NamedNodeMap

    The Element.attributes property returns a live collection of all attribute nodes registered to the specified node. It is a NamedNodeMap, not an Array, so it has no Array methods and the Attr nodes' indexes may differ among browsers. To be more specific, attributes is a key/value pair of strings that represents any information regarding that attribute.
