The HTMLParagraphElement type exposes the following members:

Properties

PropertyDescription
node_typeA code representing the type of the underlying object.
local_nameReturns the local part of the qualified name of this node.
For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as Document.createElement(), this is always null.
namespace_uriThe namespace URI of this node, or null if it is unspecified.
prefixThe namespace prefix of this node, or null if it is unspecified. When it is defined to be null, setting it has no effect
node_nameThe name of this node, depending on its type.
base_uriReturns the absolute base URL of the document containing the node.


The base URL is used to resolve relative URLs when the browser needs to obtain an absolute URL,
for example when processing the HTML img element’s src attribute or the xlink:href or href attributes in SVG.
owner_documentReturns the top-level document object of the node.
parent_nodeReturns the parent of the specified node in the DOM tree.


Document and DocumentFragment nodes can never have a parent, so will always return null. It also returns if the node has just been created and is not yet attached to the tree.
parent_elementReturns the DOM node’s parent Element, or if the node either has no parent, or its parent isn’t a DOM Element.
child_nodesReturns a live NodeList of child nodes of the given element where the first child node is assigned index 0. Child nodes include elements, text and comments.
first_childReturns the node’s first child in the tree, or null if the node has no children.


If the node is a Document, this property returns the first node in the list of its direct children.
last_childReturns the last child of the node. If its parent is an element, then the child is generally an element node, a text node, or a comment node. It returns null if there are no child elements
previous_siblingReturns the node immediately preceding the specified one in its parent’s Node.child_nodes list, or if the specified node is the first in that list.
next_siblingReturns the node immediately following the specified one in their parent’s Node.child_nodes, or returns null if the specified node is the last child in the parent element.
node_valueReturns or sets the value of the current node.
text_contentThis attribute returns the text content of this node and its descendants. When it is defined to be null, setting it has no effect. On setting, any possible children this node may have are removed and, if it the new string is not empty or null, replaced by a single Text node containing the string this attribute is set to.
ELEMENT_NODEAn element node
ATTRIBUTE_NODEAn attribute node
TEXT_NODEA text node
CDATA_SECTION_NODEA cdata section node
ENTITY_REFERENCE_NODEAn entity reference node
ENTITY_NODEAn entity node
PROCESSING_INSTRUCTION_NODEA processing instruction node
COMMENT_NODEA comment node
DOCUMENT_NODEA document node
DOCUMENT_TYPE_NODEA document type node
DOCUMENT_FRAGMENT_NODEA document fragment node
NOTATION_NODEA notation node
class_listReturns a live DOMTokenList which contains tokens received from parsing the “class” attribute.
tag_nameThe name of the element.
idThe element’s identifier. See the id attribute definition in HTML 4.01.
class_nameThe class attribute of the element. This attribute has been renamed due
to conflicts with the “class” keyword exposed by many languages. See
the class attribute definition in HTML 4.01.
attributesA NamedNodeMap containing the attributes of this node (if it is an Element) or null otherwise.
first_element_childReturns the first child element node of this element. null if this element has no child elements.
last_element_childReturns the last child element node of this element. null if this element has no child elements.
previous_element_siblingReturns the previous sibling element node of this element. null if this element has no element sibling nodes that come before this one in the document tree.
next_element_siblingReturns the next sibling element node of this element. null if this element has no element sibling nodes that come after this one in the document tree.
child_element_countReturns the current number of element nodes that are children of this element. 0 if this element has no child nodes that are of nodeType 1.
childrenReturns the child elements of current element.
inner_htmlReturns a fragment of HTML or XML that represents the element’s contents.
Can be set, to replace the contents of the element with nodes parsed from the given string.
outer_htmlReturns a fragment of HTML or XML that represents the element and its contents.
Can be set, to replace the element with nodes parsed from the given string.
shadow_rootReturns shadowRoot stored on this element or null if it’s closed.
titleThe element’s advisory title. See the title attribute definition in
HTML 4.01.
langLanguage code defined in RFC 1766. See the lang attribute definition in
HTML 4.01.
dirSpecifies the base direction of directionally neutral text and the
directionality of tables. See the dir attribute definition in HTML
4.01.
styleRepresents a style attribute that allows author to directly apply style information to specific element.
alignHorizontal text alignment. See the align attribute definition in HTML
4.01. This attribute is deprecated in HTML 4.01.

Methods

MethodDescription
add_event_listenerSets up a function that will be called whenever the specified event is delivered to the target.


It works by adding a function, or an object that implements IEventListener,
to the list of event listeners for the specified event type on the EventTarget on which it’s called.
If the function or object, is already in the list of event listeners for this target, they are not added a second time.
add_event_listenerSets up a function that will be called whenever the specified event is delivered to the target.


It works by adding a function, or an object that implements IEventListener,
to the list of event listeners for the specified event type on the EventTarget on which it’s called.
If the function or object, is already in the list of event listeners for this target, they are not added a second time.
remove_event_listenerThis method allows the removal of event listeners from the event target.
If an IEventListener is removed from an EventTarget while it is processing an event, it will not be triggered by the current actions.
Event Listeners can never be invoked after being removed.
remove_event_listenerThis method allows the removal of event listeners from the event target.
If an IEventListener is removed from an EventTarget while it is processing an event, it will not be triggered by the current actions.
Event Listeners can never be invoked after being removed.
clone_nodeReturns a duplicate of the node on which this method was called.


Cloning a node copies all of its attributes and their values, including intrinsic (inline) listeners. It does not copy event listeners added using IEventTarget.add_event_listener or those assigned to element properties (e.g., node.onclick = someFunction). Additionally, for a HTMLCanvasElement element, the painted image is not copied.
clone_nodeReturns a duplicate of the node on which this method was called. Its parameter controls if the subtree contained in a node is also cloned or not.

toggle_attributeIf force is not given, “toggles” qualifiedName, removing it if it is present and adding it if it is not present. If force is true, adds qualifiedName.
If force is false, removes qualifiedName.
toggle_attributeIf force is not given, “toggles” qualifiedName, removing it if it is present and adding it if it is not present. If force is true, adds qualifiedName.
If force is false, removes qualifiedName.
get_platform_typeThis method is used to retrieve the ECMAScript object Type.
dispatch_eventDispatches an Event at the specified IEventTarget, (synchronously) invoking
the affected EventListeners in the appropriate order.
The normal event processing rules (including the capturing and optional bubbling phase) also apply to events
dispatched manually with IEventTarget.dispatch_event.
has_child_nodesReturns a boolean value indicating whether the given Node has child nodes or not.
normalizePuts all Text nodes in the full depth of the sub-tree underneath this Node, including attribute nodes, into a “normal” form where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are neither adjacent Text nodes nor empty Text nodes. This can be used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as XPointer [XPointer] lookups) that depend on a particular document tree structure are to be used. If the parameter “normalize-characters” of the DOMConfiguration object attached to the Node.ownerDocument is true, this method will also fully normalize the characters of the Text nodes.
is_equal_nodeTests whether two nodes are equal.
This method tests for equality of nodes, not sameness (i.e., whether the two nodes are references to the same object) which can be tested with Node.isSameNode(). All nodes that are the same will also be equal, though the reverse may not be true.
is_same_nodeMethod is a legacy alias the for the strict equality operator. That is, it tests whether two nodes are the same (in other words, whether they reference the same object).
lookup_prefixLook up the prefix associated to the given namespace URI, starting from this node. The default namespace declarations are ignored by this method.
See Namespace Prefix Lookup for details on the algorithm used by this method.
lookup_namespace_uriLook up the namespace URI associated to the given prefix, starting from this node.
is_default_namespaceThis method checks if the specified namespaceURI is the default namespace or not.
insert_beforeInserts the node before the existing child node child. If child is null, insert node at the end of the list of children.
If child is a DocumentFragment object, all of its children are inserted, in the same order, before child. If the child is already in the tree, it is first removed.
replace_childReplaces the child node oldChild with newChild in the list of children, and returns the oldChild node.
If newChild is a DocumentFragment object, oldChild is replaced by all of the DocumentFragment children, which are inserted in the same order. If the newChild is already in the tree, it is first removed.
remove_childRemoves a child node from the DOM and returns the removed node.
append_childAdds a node to the end of the list of children of a specified parent node. If the given child is a reference to an existing node in the document, Node.append_child moves it from its current position to the new position (there is no requirement to remove the node from its parent node before appending it to some other node).


This means that a node can’t be in two points of the document simultaneously. So if the node already has a parent, the node is first removed, then appended at the new position. The Node.clone_node method can be used to make a copy of the node before appending it under the new parent. Copies made with Node.clone_node are not be automatically kept in sync.
get_attribute_namesReturns the attribute names of the element as an Array of strings. If the element has no attributes it returns an empty array.
has_attributesReturns whether this node (if it is an element) has any attributes
get_attributeRetrieves an attribute value by name.
get_attribute_nsRetrieves an attribute value by local name and namespace URI.
set_attributeAdds a new attribute. If an attribute with that name is already present in the element, its value is changed to be that of the value parameter
set_attribute_nsAdds a new attribute. If an attribute with the same local name and namespace URI is already present on the element, its prefix is changed to be the prefix part of the qualifiedName, and its value is changed to be the value parameter.
remove_attributeRemoves an attribute by name.
remove_attribute_nsRemoves an attribute by local name and namespace URI.
has_attributeReturns true when an attribute with a given name is specified on this element or has a default value, false otherwise.
has_attribute_nsReturns true when an attribute with a given local name and namespace URI is specified on this element or has a default value, false otherwise.
get_attribute_nodeRetrieves an attribute node by name.
set_attribute_nodeAdds a new attribute node. If an attribute with that name (nodeName) is already present in the element, it is replaced by the new one.
remove_attribute_nodeRemoves the specified attribute node.
get_attribute_node_nsRetrieves an Attr node by local name and namespace URI.
set_attribute_node_nsAdds a new attribute. If an attribute with that local name and that namespace URI is already present in the element, it is replaced by the new one.
get_elements_by_tag_nameReturns HTMLCollection object containing all Element with a given tag name, in document order.
get_elements_by_tag_name_nsReturns HTMLCollection object containing all Element with a given local name and namespace URI string in document order.
removeRemoves this instance.
query_selector_allReturns a NodeList of all the Elements in document, which match selector
query_selectorReturns the first Element in document, which match selector
attach_shadowCreates shadow root and attaches it to current element.
get_elements_by_class_nameReturns HTMLCollection object containing all the elements within Element that have all the classes specified in argument.
