HTMLSourceElement
The HTMLSourceElement
interface provides special properties (beyond the regular HTMLElement
object interface it also has available to it by inheritance) for manipulating <source>
elements.
Instance properties
Inherits properties from its parent, HTMLElement
.
HTMLSourceElement.height
-
A number that reflects the
height
HTML attribute, indicating the height of the image resource in CSS pixels. The property has a meaning only if the parent of the current<source>
element is a<picture>
element. HTMLSourceElement.media
-
A string reflecting the
media
HTML attribute, containing the intended type of the media resource. HTMLSourceElement.sizes
-
A string representing image sizes between breakpoints
HTMLSourceElement.src
-
A string reflecting the
src
HTML attribute, containing the URL for the media resource. TheHTMLSourceElement.src
property has a meaning only when the associated<source>
element is nested in a media element that is a<video>
or an<audio>
element. It has no meaning and is ignored when it is nested in a<picture>
element.Note: If the
src
property is updated (along with any siblings), the parentHTMLMediaElement
'sload
method should be called when done, since<source>
elements are not re-scanned automatically. HTMLSourceElement.srcset
-
A string 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. HTMLSourceElement.type
-

type
HTML attribute, containing the type of the media resource. HTMLSourceElement.width
