SVGUseElement

SVG使用DOM接口

该SVGUseElement接口对应于<use>元素。

性质

此接口还从其父接口SVGGraphicsElement 继承属性，并从SVGURIReference实现属性。

SVGUseElement.x 只读: An SVGAnimatedLength corresponding to the x attribute of the given element.
SVGUseElement.y 只读: An SVGAnimatedLength corresponding to the y attribute of the given element.
SVGUseElement.width 只读: An SVGAnimatedLength corresponding to the width attribute of the given element.
SVGUseElement.height 只读: An SVGAnimatedLength corresponding to the height attribute of the given element.
SVGUseElement.instanceRoot 只读: An SVGElement corresponding to the instance root of the given element, which is a direct child of the elements shadow root. If the element does not have a shadow tree (for example, because its URI is invalid or because it has been disabled by conditional processing), then getting this attribute returns null.
SVGUseElement.animatedInstanceRoot 只读: An SVGElement corresponding to the instance root of the given element, which is a direct child of the elements shadow root. If the element does not have a shadow tree (for example, because its URI is invalid or because it has been disabled by conditional processing), then getting this attribute returns null.

Methods

This interface doesn't implement any specific methods, but inherits methods from its parent interface, SVGGraphicsElement and implements methods from SVGURIReference.
