Methods

add(JSAny? any) → JSAny

Available on JSAny?, provided by the JSAnyOperatorExtension extension

The result of this + any in JavaScript.

and(JSAny? any) → JSAny?

Available on JSAny?, provided by the JSAnyOperatorExtension extension

callMethod<R extends JSAny?>(JSAny method, [JSAny? arg1, JSAny? arg2, JSAny? arg3, JSAny? arg4]) → R

Available on JSObject, provided by the JSObjectUnsafeUtilExtension extension

Calls method on this JSObject with up to four arguments.

callMethodVarArgs<R extends JSAny?>(JSAny method, [List<JSAny?>? arguments]) → R

Available on JSObject, provided by the JSObjectUnsafeUtilExtension extension

Calls method on this JSObject with a variable number of arguments.

createDocument(String? namespace, String qualifiedName, [DocumentType? doctype]) → XMLDocument

The DOMImplementation.createDocument() method creates and returns an XMLDocument.

createDocumentType(String qualifiedName, String publicId, String systemId) → DocumentType

The DOMImplementation.createDocumentType() method returns a DocumentType object which can either be used with DOMImplementation.createDocument upon document creation or can be put into the document via methods like Node.insertBefore or Node.replaceChild.

createHTMLDocument([String title]) → Document

The DOMImplementation.createHTMLDocument() method creates a new HTML Document.

dartify() → Object?

Available on JSAny?, provided by the JSAnyUtilityExtension extension

Converts a JavaScript JSON-like value to the Dart equivalent if possible.

delete(JSAny property) → JSBoolean

Available on JSObject, provided by the JSObjectUnsafeUtilExtension extension
