SVGElement - Web APIs 编辑

All of the SVG DOM interfaces that correspond directly to elements in the SVG language derive from the SVGElement interface.

  <div id="interfaceDiagram" style="display: inline-block; position: relative; width: 100%; padding-bottom: 11.666666666666666%; vertical-align: middle; overflow: hidden;"><svg style="display: inline-block; position: absolute; top: 0; left: 0;" viewbox="-50 0 600 70" preserveAspectRatio="xMinYMin meet"><a xlink:href="/wiki/en-US/docs/Web/API/EventTarget" target="_top"><rect x="1" y="1" width="110" height="50" fill="#fff" stroke="#D4DDE4" stroke-width="2px" /><text  x="56" y="30" font-size="12px" font-family="Consolas,Monaco,Andale Mono,monospace" fill="#4D4E53" text-anchor="middle" alignment-baseline="middle">EventTarget</text></a><polyline points="111,25  121,20  121,30  111,25" stroke="#D4DDE4" fill="none"/><line x1="121" y1="25" x2="151" y2="25" stroke="#D4DDE4"/><a xlink:href="/wiki/en-US/docs/Web/API/Node" target="_top"><rect x="151" y="1" width="75" height="50" fill="#fff" stroke="#D4DDE4" stroke-width="2px" /><text  x="188.5" y="30" font-size="12px" font-family="Consolas,Monaco,Andale Mono,monospace" fill="#4D4E53" text-anchor="middle" alignment-baseline="middle">Node</text></a><polyline points="226,25  236,20  236,30  226,25" stroke="#D4DDE4" fill="none"/><line x1="236" y1="25" x2="266" y2="25" stroke="#D4DDE4"/><a xlink:href="https://developer.mozilla.org/wiki/en-US/docs/Web/API/Element" target="_top"><rect x="266" y="1" width="75" height="50" fill="#fff" stroke="#D4DDE4" stroke-width="2px" /><text  x="303.5" y="30" font-size="12px" font-family="Consolas,Monaco,Andale Mono,monospace" fill="#4D4E53" text-anchor="middle" alignment-baseline="middle">Element</text></a><polyline points="341,25  351,20  351,30  341,25" stroke="#D4DDE4" fill="none"/><line x1="351" y1="25" x2="381" y2="25" stroke="#D4DDE4"/><a xlink:href="https://developer.mozilla.org/wiki/en-US/docs/Web/API/SVGElement" target="_top"><rect x="381" y="1" width="100" height="50" fill="#F4F7F8" stroke="#D4DDE4" stroke-width="2px" /><text  x="431" y="30" font-size="12px" font-family="Consolas,Monaco,Andale Mono,monospace" fill="#4D4E53" text-anchor="middle" alignment-baseline="middle">SVGElement</text></a></svg></div>

Properties

Also inherits properties from: DocumentAndElementEventHandlers, Element, ElementCSSInlineStyle, GlobalEventHandlers, HTMLOrForeignElement, SVGElementInstance

SVGElement.datasetRead only

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.className Read only

An SVGAnimatedString that reflects the value of the class attribute on the given element, or the empty string if class is not present. This attribute is deprecated and may be removed in a future version of this specification. Authors are advised to use Element.classList instead.

SVGElement.ownerSVGElementRead only

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

SVGElement.viewportElementRead only

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

Methods

This interface has no methods, but inherits methods from: DocumentAndElementEventHandlers, Element, ElementCSSInlineStyle, GlobalEventHandlers, HTMLOrForeignElement, SVGElementInstance

Events

Listen to these events using addEventListener() or by assigning an event listener to the equivalent on... handler property defined on GlobalEventHandlers or WindowEventHandlers.

abort

Fired when page loading is stopped before an SVG element has been allowed to load completely.
Also available via the onabort property.

error

Fired when an SVG element does not load properly or when an error occurs during script execution.
Also available via the onerror property.

load

Fires on an SVGElement when it is loaded in the browser.
