JavaScript constructor.

Overrides:

jsConstructor in class Node

append

public static void append(org.htmlunit.corejs.javascript.Context context,
                          org.htmlunit.corejs.javascript.Scriptable scope,
                          org.htmlunit.corejs.javascript.Scriptable thisObj,
                          Object[] args,
                          org.htmlunit.corejs.javascript.Function function)

Inserts a set of Node objects or string objects after the last child of the document fragment. String objects are inserted as equivalent Text nodes.

Parameters:

context - the context

scope - the scope

thisObj - this object

args - the arguments

function - the function

prepend

public static void prepend(org.htmlunit.corejs.javascript.Context context,

Replaces the existing children of a DocumentFragment with a specified new set of children. These can be string or Node objects.

Parameters:

context - the context

scope - the scope

thisObj - this object

args - the arguments

function - the function

querySelectorAll

public NodeList querySelectorAll(String selectors)

Retrieves all element nodes from descendants of the starting element node that match any selector within the supplied selector strings. The NodeList object returned by the querySelectorAll() method must be static, not live.

Parameters:

Returns:

the static node list

querySelector

public Node querySelector(String selectors)

Returns the first element within the document that matches the specified group of selectors.

Parameters:
