HTMLElement

View on MDN ↗

The HTMLElement interface represents any HTML element. Some elements directly implement this interface, while others implement it via an interface that inherits it.

Instance properties

Also inherits properties from its parent, Element.

  • accessKey
    • : A string representing the access key assigned to the element.
  • accessKeyLabel Read only
    • : Returns a string containing the element’s assigned access key.
  • anchorElement Read only  Experimental
    • : Returns a reference to the element’s anchor element, or null if it doesn’t have one.
  • attributeStyleMap Read only
  • autocapitalize
    • : A string that represents the element’s capitalization behavior for user input. Valid values are: none, off, on, characters, words, sentences.
  • autofocus
    • : A boolean value reflecting the autofocus HTML global attribute, which indicates whether the control should be focused when the page loads, or when dialog or popover become shown if specified in an element inside <dialog> elements or elements whose popover attribute is set.
  • autocorrect
    • : A boolean that represents whether or not text input by a user should be automatically corrected. This reflects the autocorrect HTML global attribute.
  • contentEditable
    • : A string, where a value of true means the element is editable and a value of false means it isn’t.
  • dataset Read only
  • dir
    • : A string, reflecting the dir global attribute, representing the directionality of the element. Possible values are "ltr", "rtl", and "auto".
  • draggable
    • : A boolean value indicating if the element can be dragged.
  • editContext Experimental
    • : Returns the EditContext associated with the element, or null if there isn’t one.
  • enterKeyHint
    • : A string defining what action label (or icon) to present for the enter key on virtual keyboards.
  • hidden
    • : A string or boolean value reflecting the value of the element’s hidden attribute.
  • inert
    • : A boolean value indicating whether the user agent must act as though the given node is absent for the purposes of user interaction events, in-page text searches (“find in page”), and text selection.
  • innerText
    • : Represents the rendered text content of a node and its descendants. As a getter, it approximates the text the user would get if they highlighted the contents of the element with the cursor and then copied it to the clipboard. As a setter, it replaces the content inside the selected element, converting any line breaks into <br> elements.
  • inputMode
    • : A string value reflecting the value of the element’s inputmode attribute.
  • isContentEditable Read only
    • : Returns a boolean value indicating whether or not the content of the element can be edited.
  • lang
    • : A string representing the language of an element’s attributes, text, and element contents.
  • nonce
    • : Returns the cryptographic number used once that is used by Content Security Policy to determine whether a given fetch will be allowed to proceed.
  • offsetHeight Read only
    • : Returns a double containing the height of an element, relative to the layout.
  • offsetLeft Read only
    • : Returns a double, the distance from this element’s left border to its offsetParent’s left border.
  • offsetParent Read only
    • : An Element that is the element from which all offset calculations are currently computed.
  • offsetTop Read only
    • : Returns a double, the distance from this element’s top border to its offsetParent’s top border.
  • offsetWidth Read only
    • : Returns a double containing the width of an element, relative to the layout.
  • outerText
    • : Represents the rendered text content of a node and its descendants. As a getter, it is the same as innerText (it represents the rendered text content of an element and its descendants). As a setter, it replaces the selected node and its contents with the given value, converting any line breaks into <br> elements.
  • popover
    • : Gets and sets an element’s popover state via JavaScript ("auto", "hint", or "manual"), and can be used for feature detection. Reflects the value of the popover global HTML attribute.
  • spellcheck
    • : A boolean value that controls the spell-checking hint. It is available on all HTML elements, though it doesn’t affect all of them.
  • style
  • tabIndex
    • : A long representing the position of the element in the tabbing order.
  • title
    • : A string containing the text that appears in a popup box when mouse is over the element.
  • translate
    • : A boolean value representing the translation.
  • virtualKeyboardPolicy Experimental
    • : A string indicating the on-screen virtual keyboard behavior on devices such as tablets, mobile phones, or other devices where a hardware keyboard may not be available, if the element’s content is editable (for example, it is an <input> or <textarea> element, or an element with the contenteditable attribute set).
  • writingSuggestions
    • : A string indicating if browser-provided writing suggestions should be enabled under the scope of the element or not.

Instance methods

Also inherits methods from its parent, Element.

  • attachInternals()
    • : Returns an ElementInternals object, and enables a custom element to participate in HTML forms.
  • blur()
    • : Removes keyboard focus from the currently focused element.
  • click()
    • : Sends a mouse click event to the element.
  • focus()
    • : Makes the element the current keyboard focus.
  • hidePopover()
    • : Hides a popover element by removing it from the top layer and styling it with display: none.
  • showPopover()
    • : Shows a popover element by adding it to the top layer and removing display: none; from its styles.
  • togglePopover()
    • : Toggles a popover element between the hidden and showing states.

Events

Listen to these events using addEventListener() or by assigning an event listener to the oneventname property of this interface.

Also, inherits events from its parent, Element.

  • change
    • : Fired when the value of an <input>, <select>, or <textarea> element has been changed and committed by the user. Unlike the input event, the change event is not necessarily fired for each alteration to an element’s value.
  • command
    • : Fires on an element that is controlled via a button with valid commandForElement and command values, whenever the button is interacted with (e.g., it is clicked).
  • error
    • : Fired when a resource failed to load, or can’t be used.
  • load
    • : Fires for elements containing a resource when the resource has successfully loaded.

Drag & drop events

  • drag
    • : This event is fired when an element or text selection is being dragged.
  • dragend
    • : This event is fired when a drag operation is being ended (by releasing a mouse button or hitting the escape key).
  • dragenter
    • : This event is fired when a dragged element or text selection enters a valid drop target.
  • dragleave
    • : This event is fired when a dragged element or text selection leaves a valid drop target.
  • dragover
    • : This event is fired continuously when an element or text selection is being dragged and the mouse pointer is over a valid drop target (every 50 ms WHEN mouse is not moving ELSE much faster between 5 ms (slow movement) and 1ms (fast movement) approximately. This firing pattern is different than mouseover ).
  • dragstart
    • : This event is fired when the user starts dragging an element or text selection.
  • drop
    • : This event is fired when an element or text selection is dropped on a valid drop target.

Interest invoker events

  • interest Experimental
    • : Fired on the target element of an interest invoker when interest is shown, allowing code to be run in response.
  • loseinterest Experimental
    • : Fired on the target element of an interest invoker when interest is lost, allowing code to be run in response.
