Deprecated since SVG 2
This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the 兼容性表格 at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

SVGPathElement.pathLength property reflects the pathLength attribute and returns the total length of the path, in user units.

注意： In SVG 2 this property was moved to the SVGGeometryElement interface, from which the SVGPathElement inherits it.

句法

var pathLength = someElement.pathLength;
