Document extension type

The Document interface represents any web page loaded in the browser and serves as an entry point into the web page's content, which is the DOM tree.

The DOM tree includes elements such as body and table, among many others. It provides functionality globally to the document, like how to obtain the page's URL and create new elements in the document.

The Document interface describes the common properties and methods for any kind of document. Depending on the document's type (e.g. HTML, XML, SVG, …), a larger API is available: HTML documents, served with the "text/html" content type, also implement the HTMLDocument interface, whereas XML and SVG documents implement the XMLDocument interface.

inherited
lookupPrefix(String? namespace) → String?
The lookupPrefix() method of the Node interface returns a string containing the prefix for a given namespace URI, if present, and null if not. When multiple prefixes are possible, the first prefix is returned.
inherited
modulo(JSAny? any) → JSAny

Available on JSAny?, provided by the JSAnyOperatorExtension extension

The result of this % any in JavaScript.
multiply(JSAny? any) → JSAny

Available on JSAny?, provided by the JSAnyOperatorExtension extension

The result of this * any in JavaScript.
normalize() → void
The normalize() method of the Node interface puts the specified node and all of its sub-tree into a normalized form. In a normalized sub-tree, no text nodes in the sub-tree are empty and there are no adjacent text nodes.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notEquals(JSAny? any) → JSBoolean

Available on JSAny?, provided by the JSAnyOperatorExtension extension

The result of this != any in JavaScript.
open([String unused1OrUrl, String nameOrUnused2, String features]) → JSObject?
The Document.open() method opens a document for Document.write.
or(JSAny? any) → JSAny?

Available on JSAny?, provided by the JSAnyOperatorExtension extension

The result of this || any in JavaScript.
prepend(JSAny nodes) → void
The Document.prepend() method inserts a set of Node objects or string objects before the first child of the document. String objects are inserted as equivalent Text nodes.
queryCommandIndeterm(String commandId) → bool
queryCommandValue(String commandId) → String
querySelector(String selectors) → Element?
The Document method querySelector() returns the first Element within the document that matches the specified selector, or group of selectors. If no matches are found, null is returned.
querySelectorAll(String selectors) → NodeList
The Document method querySelectorAll() returns a static (not live) NodeList representing a list of the document's elements that match the specified group of selectors.
releaseEvents() → void
removeChild(Node child) → Node
The removeChild() method of the Node interface removes a child node from the DOM and returns the removed node.
inherited
removeEventListener(String type, EventListener? callback, [JSAny options]) → void
The removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget.addEventListener from the target. The event listener to be removed is identified using a combination of the event type, the event listener function itself, and various optional options that may affect the matching process; see Matching event listeners for removal.
inherited
replaceChild(Node node, Node child) → Node
The replaceChild() method of the Node interface replaces a child node within the given (parent) node.
inherited
replaceChildren(JSAny nodes) → void
The Document.replaceChildren() method replaces the existing children of a Document with a specified new set of children.
requestStorageAccess() → JSPromise<JSAny?>
The requestStorageAccess() method of the Document interface allows content loaded in a third-party context (i.e., embedded in an iframe) to request access to third-party cookies and unpartitioned state. This is relevant to user agents that, by default, block access to third-party, unpartitioned cookies to improve privacy (e.g., to prevent tracking), and is part of the Storage Access API.
setProperty(JSAny property, JSAny? value) → void

Available on JSObject, provided by the JSObjectUnsafeUtilExtension extension

Write the value of property key property of this JSObject.
startViewTransition([JSObject callbackOptions]) → ViewTransition
The startViewTransition() method of the Document interface starts a new same-document (SPA) view transition and returns a ViewTransition object to represent it.
strictEquals(JSAny? any) → JSBoolean

Available on JSAny?, provided by the JSAnyOperatorExtension extension

The result of this === any in JavaScript.
strictNotEquals(JSAny? any) → JSBoolean

Available on JSAny?, provided by the JSAnyOperatorExtension extension

The result of this !== any in JavaScript.
subtract(JSAny? any) → JSAny

Available on JSAny?, provided by the JSAnyOperatorExtension extension

The result of this - any in JavaScript.
toString() → String
A string representation of this object.
inherited
typeofEquals(String typeString) → bool

Available on JSAny?, provided by the JSAnyUtilityExtension extension

Whether the result of typeof on this JSAny? is typeString.
unsignedRightShift(JSAny? any) → JSNumber

Available on JSAny?, provided by the JSAnyOperatorExtension extension

The result of this >>> any in JavaScript.
write(JSAny text) → void

Warning: Use of the document.write() method is strongly discouraged.

As the HTML spec itself warns:

This method has very idiosyncratic behavior. In some cases, this method can affect the state of the

HTML parser while the parser is running, resulting in a DOM that does not correspond to the source of the document (e.g. if the string written is the string "<plaintext>" or "<!--"). In other cases, the call can clear the current page first, as if document.open() had been called. In yet more cases, the method is simply ignored, or throws an exception. Users agents are explicitly allowed to avoid executing script elements inserted via this method. And to make matters even worse, the exact behavior of this method can in some cases be dependent on network latency, which can lead to failures that are very hard to debug. For all these reasons, use of this method is strongly discouraged.

Therefore, avoid using document.write() — and if possible, update any existing code that is still using it.

inherited
operator [](String name) → JSObject
operator [](String property) → JSAny?

Shorthand helper for setProperty to write the value of the property key property of this JSObject, but takes a Dart value.

Static Methods

parseHTMLUnsafe(JSAny html) → Document
The parseHTMLUnsafe() static method of the Document object is used to parse a string of HTML, which may contain declarative shadow roots, in order to create a new Document instance.
