HTMLSourceElement

View on MDN ↗

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.

  • 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.

  • media

    • : A string reflecting the media HTML attribute, containing the intended type of the media resource.

  • sizes

    • : A string representing image sizes between breakpoints

  • src

    • : A string reflecting the src HTML attribute, containing the URL for the media resource. The 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.

  • 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.

  • type

    • : A string reflecting the type HTML attribute, containing the type of the media resource.

  • width

    • : A number that reflects the width HTML attribute, indicating the width 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.

Instance methods

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