EventDescription
onload

Occurs when the browser has fully parsed the element and all of its descendants.

 

Methods

The SVGAElement object has these methods.

MethodDescription
getBBox

Gets the bounding box, in current user space, of the geometry of all contained graphics elements.

getCTM

Gets the transformation matrix that transforms from the current user units to the viewport coordinate system for the nearestViewportElement object.

getScreenCTM

Gets the transformation matrix from the current user units to the screen coordinate system.

getTransformToElement

Gets the transformation matrix that transforms from the user coordinate system on the current element to the user coordinate system on the specified target element.

hasExtension

Determines if the specified extension is supported.

 

Properties

The SVGAElement object has these properties.

PropertyDescription

className

Gets the names of the classes that are assigned to this object.

externalResourcesRequired

Gets a value that indicates whether referenced resources that are not in the current document are required to correctly render a given element.

farthestViewportElement

Gets a value that represents the farthest ancestor svg element.

focusable

systemLanguage

Gets or sets a comma-separated list of language names.

target

Specifies where to open a linked document.

transform

Gets the value of a transform attribute.

viewportElement

Gets the element that established the current viewport.

xmlbase

Gets or sets the base attribute on the element.

Standards information

Remarks

Note  In addition to the attributes, properties, events, methods, and styles listed above, SVG elements also inherit core HTML attributes, properties, events, methods, and styles.

SVG provides an a element to indicate links (also known as hyperlinks or web links). The a element may contain any element that its parent may contain, except itself.

SVG uses XLink for all link definitions (that is, xmlns:xlink="http://www.w3.org/1999/xlink" must be present in the containing svg element). Each link associates exactly two resources, one local and one remote, going from the former to the latter.

A link is defined for each separate rendered element contained within the a element; thus, if the a element contains three circle elements, a link is created for each circle. For each rendered element within an a element, the given rendered element is the local resource (the source anchor for the link).

The remote resource (the destination for the link) is defined by a URL (technically a W3C IRI) specified by the XLink (that is, xlink:href attribute) on the a element. The remote resource may be any web resource (for example, an image, a video clip, a sound bite, a program, another SVG document, an HTML document, an element within the current document, an element within a different document, etc.). By activating these links (by clicking with the mouse, through keyboard input, by voice commands, etc.), users may visit these resources.

Examples

In the following code example, the a element is used to create a hyperlink using the xlink namespace. The link is attached to the circle element inside an inline SVG element. Copy this sample to a text file and save it with the .html file extension. Run it in Internet Explorer 9 and click on the chocolate circle.

It should look like this:
