SVGElement

所有SVG DOM类的父类.

属性

SVGElement.dataset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-*, 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 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.
