SVGElement

SVGElement.dataset (en-US)只读

A DOMStringMap object which provides a list of key/value pairs of named data attributes which correspond to custom data attributes attached to the element. These can also be defined in SVG using attributes of the form data-* (en-US), where * is the key name for the pair. This works just like HTML's HTMLElement.dataset property and HTML's data-* global attribute.

SVGElement.id只读

A DOMString representing the value of the id attribute on the given element, or the empty string if id is not present.

SVGElement.xmlbase只读

A DOMString corresponding to the xml:base (en-US) attribute on the given element.

SVGElement.ownerSVGElement只读

An SVGSVGElement referring to the nearest ancestor <svg> element. null if the given element is the outermost <svg> element.

SVGElement.viewportElement只读

The SVGElement, which established the current viewport. Often, the nearest ancestor <svg> element. null if the given element is the outermost <svg> element.
