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.

Properties

Inherits properties from its parent, HTMLElement.

HTMLSourceElement.media

Is a DOMString reflecting the media HTML attribute, containing the intended type of the media resource.

HTMLSourceElement.sizes

Is a DOMString representing image sizes between breakpoints

HTMLSourceElement.src

Is a DOMString reflecting the src HTML attribute, containing the URL for the media resource. The HTMLSourceElement.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 parent HTMLMediaElement's load method should be called when done, since <source> elements are not re-scanned automatically.

HTMLSourceElement.srcset

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.

HTMLSourceElement.type

Is a DOMString reflecting the type HTML attribute, containing the type of the media resource.

Methods

No specific method; inherits methods from its parent, HTMLElement.
