link.source()
Return a shallow copy of the source
property of the link.
If the beginning of the link is connected to an element, an object in the format { id: elementID }
is returned. If the beginning of the link is specified as a point instead (the link is pinned
to the paper at that point), an object in the format { x: sourceX, y: sourceY }
is returned. Furthermore, any additional arguments of the source are returned alongside those properties.
If you need to be sure that an Element is returned (and not a Point), use the link.getSourceElement
function instead.
link.source(source [, opt])
Set the source
of the link.
If the link is to be connected to an element, send an object in the format { id: element.id }
(or a joint.dia.Element
object). If the link is to be pinned to the paper, send an object in the format { x: sourceX, y: sourceY }
(or a g.Point
object).
link.source(rect);
link.source({ id: rect.id });
link.source(new g.Point(100, 100));
link.source({ x: 100, y: 100 });
Additional options may by provided to further specify the behavior of link at the source:
link.source(rect, {
selector: 'body',
anchor: {
name: 'bottomLeft',
args: {
dx: 20,
dy: -10
}
}
});

documentation.
