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:
<!DOCTYPE HTML> <html> <head></head> <body> <!-- Create an SVG object --> <svg width="400" height="400"> <!-- Create a link. --> <a xlink:href="http://msdn.microsoft.com/en-us/ie/"> <!-- Create a circle. --> <circle cx="100" cy="100" r="50" fill="chocolate"/> </circle> </a> </svg> </body> </html>
Note: In addition to the attributes, properties, events, methods, and styles listed above, SVG elements also inherent 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 [http://go.microsoft.com/fwlink/p/?linkid=203507 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.
- Scalable Vector Graphics: Linking, Section 17.4.1
The SVGAElement object has these events:
- onload: Occurs when the browser has fully parsed the element and all of its descendants.
The SVGAElement object has these methods:
- 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.
The SVGAElement object has these properties:
- 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: Determines if an element can acquire keyboard focus (that is, receive keyboard events) and be a target for field-to-field navigation actions (such as when a user presses the Tab key).
- href: Gets an xlink:href attribute of an element.
- nearestViewportElement: Gets a value that indicates which element established the current viewport.
- ownerSVGElement: Gets the nearest ancestor svg element.
- requiredExtensions: Gets a white space-delimited list of required language extensions.
- requiredFeatures: Gets or sets a white space-delimited list of feature strings.
- style: Gets a style object.
- 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.
- xmllang: Gets or sets a value that specifies the language that is used in the contents and attribute values of an element.
- xmlspace: Gets or sets a value that indicates whether white space is preserved in character data.
