Variables

align:String

Is a DOMString indicating the alignment of the image with respect to the surrounding context.

alt:String

Is a DOMString that reflects the alt HTML attribute,  thus indicating fallback context for the image.

border:String

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.

read onlycomplete:Bool

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.

crossOrigin:String

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).

height:Int

Is a unsigned long that reflects the height HTML attribute, indicating the rendered height of the image in CSS pixels.

hspace:Int

Is a long representing the space on either side of the image.

isMap:Bool

Is a Boolean that reflects the ismap HTML attribute, indicating that the image is part of a server-side image map.

longDesc:String

Is a DOMString representing the URI of a long description of the image.

lowsrc:String

name:String

Is a DOMString representing the name of the element.

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.

sizes:String

Is a DOMString reflecting the sizes HTML attribute.

src:String

Is a DOMString that reflects the src HTML attribute, containing the full URL of the image including base URI.

srcset:String

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.

useMap:String

Is a DOMString that reflects the usemap HTML attribute, containing a partial URL of a map element.

vspace:Int

Is a long representing the space above and below the image.

width:Int

Is a unsigned long that reflects the width HTML attribute, indicating the rendered width of the image in CSS pixels.

read onlyx:Int

Returns a long representing the horizontal offset from the nearest layer. This property mimics an old Netscape 4 behavior.

read onlyy:Int

Returns a long representing the vertical offset from the nearest layer. This property is also similar to behavior of an old Netscape 4.

Defined by Node

read onlybaseURI:String

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

Returns a live NodeList containing all the children of this node. NodeList being live means that if the children of the Node change, the NodeList object is automatically updated.

read onlyfirstChild:Node

Returns a Node representing the first direct child node of the node, or null if the node has no child.

read onlylastChild:Node

Returns a Node representing the last direct child node of the node, or null if the node has no child.

read onlylocalName:String

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.

read onlynodeName:String

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.

read onlynodeType:Int

Returns an unsigned short representing the type of the node. Possible values are:

Name Value

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

nodeValue:String

Returns / Sets the value of the current node

read onlyownerDocument:HTMLDocument

Returns the Document that this node belongs to. If no document is associated with it, returns null.

read onlyparentElement:Element

Returns an Element that is the parent of this node. If the node has no parent, or if that parent is not an Element, this property returns null.

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 onlyprefix:String

Is a DOMString representing the namespace prefix of the node, or null if no prefix is specified.

read onlypreviousSibling:Node

Returns a Node representing the previous node in the tree, or null if there isn't such node.

textContent:String

Returns / Sets the textual content of an element and all its descendants.
