检查svg元素是否在视图框内

Question

having a SVG inline an HTML document , with a viewbox "xywh". How can I check if an element is inside the view box?

by saying element it could be a nested child path inside a group and so on ...

so I think I'm looking for a build in function of SVG ,or a quick fast why to check it.

I've tried saving the viewbox cords ,and the element I want to check if it's inside the viewbox I did something like :

while (parent ! the svg element ...)
{
   parent = get elem parent 
} 

// now I have the most top parent of this element ,inside the svg doc now check if parent inside viewbox , if true then child also , otherwise false

也许你可以尝试SVGSVGElement的checkEnclosure方法。
