Available on HTML5
Constructor
Inherited Variables
Defined by ImageElement
Is a DOMString
that reflects the alt
HTML attribute, thus indicating fallback context for the image.
Is a DOMString
that is responsible for the width of the border surrounding the image. This is now deprecated and the CSS border
property should be used instead.
Returns a Boolean
that is true
if the browser has finished fetching the image, whether successful or not. It also shows true, if the image has no HTMLImageElement.src
value.
Is a DOMString
representing the CORS setting for this image element. See CORS settings attributes for further details.
read onlycurrentSrc:String
Returns a DOMString
representing the URL to the currently displayed image (which may change, for example in response to media queries).
Is a unsigned long
that reflects the height
HTML attribute, indicating the rendered height of the image in CSS pixels.
Is a Boolean
that reflects the ismap
HTML attribute, indicating that the image is part of a server-side image map.
read onlynaturalHeight:Int
Returns a unsigned long
representing the intrinsic height of the image in CSS pixels, if it is available; else, it shows 0
.
read onlynaturalWidth:Int
Returns a unsigned long
representing the intrinsic width of the image in CSS pixels, if it is available; otherwise, it will show 0
.
Is a DOMString
that reflects the src
HTML attribute, containing the full URL of the image including base URI.
Is a DOMString
reflecting the srcset
HTML attribute, containing a list of candidate images, separated by a comma (',', U+002C COMMA
). A candidate image is a URL followed by a 'w'
with the width of the images, or an 'x'
followed by the pixel density.
Is a unsigned long
that reflects the width
HTML attribute, indicating the rendered width of the image in CSS pixels.

Defined by Node
Returns a DOMString
representing the base URL. The concept of base URL changes from one language to another; in HTML, it corresponds to the protocol, the domain name and the directory structure, that is all until the last '/'
.
read onlychildNodes:NodeList
read onlyfirstChild:Node
Returns a Node
representing the first direct child node of the node, or null
if the node has no child.
Returns a Node
representing the last direct child node of the node, or null
if the node has no child.
Returns a DOMString
representing the local part of the qualified name of an element.
Note: In Firefox 3.5 and earlier, the property upper-cases the local name for HTML elements (but not XHTML elements). In later versions, this does not happen, so the property is in lower case for both HTML and XHTML. 1.9.2
read onlynamespaceURI:String
The namespace URI of this node, or null
if it is no namespace.
Note: In Firefox 3.5 and earlier, HTML elements are in no namespace. In later versions, HTML elements are in the https://www.w3.org/1999/xhtml/
namespace in both HTML and XML trees. 1.9.2
read onlynextSibling:Node
Returns a Node
representing the next node in the tree, or null
if there isn't such node.
Returns a DOMString
containing the name of the Node
. The structure of the name will differ with the name type. E.g. An HTMLElement
will contain the name of the corresponding tag, like 'audio'
for an HTMLAudioElement
, a Text
node will have the '#text'
string, or a Document
node will have the '#document'
string.
Returns an unsigned short
representing the type of the node. Possible values are:
ELEMENT_NODE |
1 |
ATTRIBUTE_NODE (deprecated) |
2 |
TEXT_NODE |
3 |
CDATA_SECTION_NODE (deprecated) |
4 |
ENTITY_REFERENCE_NODE (deprecated) |
5 |
ENTITY_NODE (deprecated) |
6 |
PROCESSING_INSTRUCTION_NODE |
7 |
COMMENT_NODE |
8 |
DOCUMENT_NODE |
9 |
DOCUMENT_TYPE_NODE |
10 |
DOCUMENT_FRAGMENT_NODE |
11 |
NOTATION_NODE (deprecated) |
12 |
read onlyownerDocument:HTMLDocument
Returns the Document
that this node belongs to. If no document is associated with it, returns null
.
read onlyparentElement:Element
read onlyparentNode:Node
Returns a Node
that is the parent of this node. If there is no such node, like if this node is the top of the tree or if doesn't participate in a tree, this property returns null
.
read onlypreviousSibling:Node
Returns a Node
representing the previous node in the tree, or null
if there isn't such node.
