SVGGeometryElement - Web API 接口参考 编辑

The SVGGeometryElement interface represents SVG elements whose rendering is defined by geometry with an equivalent path, and which can be filled and stroked. This includes paths and the basic shapes.

  a:hover text { fill: #0095DD; pointer-events: all;}

Note: The pathLength property and the getTotalLength() and getPointAtLength() methods were originally part of the SVGPathElement interface. In SVG 2 they were moved to this interface.

Properties

This interface also inherits properties from its parent, SVGGraphicsElement.

SVGGeometryElement.pathLength 只读

This property reflects the pathLength attribute.

Methods

This interface also inherits methods from its parent, SVGGraphicsElement.

SVGGeometryElement.isPointInFill()

Determines whether a given point is within the fill shape of an element. Normal hit testing rules apply; the value of the pointer-events property on the element determines whether a point is considered to be within the fill.

SVGGeometryElement.isPointInStroke()

Determines whether a given point is within the stroke shape of an element. Normal hit testing rules apply; the value of the pointer-events property on the element determines whether a point is considered to be within the stroke.

SVGGeometryElement.getTotalLength()

Returns the user agent's computed value for the total length of the path in user units.

SVGGeometryElement.getPointAtLength()

Returns the point at a given distance along the path.
