The method describes addEventListener () to add a handle to the document adoptNode (node) to return the adapded node from another document to the current document. Close () closes the output stream opened with the document.open () method and displays the selected data.

CreateTextNode () creates a text node. GetElementsByClassName () returns a collection of all the elements in the document with the specified class name as NodeList objects. GetElementById () returns a reference to the first object that owns the specified id. GetElementsByName () returns a collection of objects with the specified name. GetElementsByTagName () returns a collection of objects with the specified tag signature. ImportNode () copies a node from another document to that document for application. Normalize () deletes empty text nodes and connects neighboring nodes normalizeDocument () deletes empty text nodes, and open () that connects neighboring nodes opens a stream to collect output from any [xss_clean] () or [xss_clean] ln () methods. QuerySelector () returns the first element in the document that matches the specified CSS selector querySelectorAll () document.querySelectorAll () is a new method introduced in HTML5 that returns a list of all element nodes of the matching CSS selector in the document removeEventListener () removes the event handle (added by the addEventListener () method) renameNode () renames the element or attribute node.
