If the node parent has .children
property, then the current node is expanded, otherwise if the node parent has _children
property then current node is collapsed
You're right that I can get that info from the handlers implemented by the library like onNodeClick
and onExpandOrCollapse
.
Since I was seeing the _expanded
property being modified in the original data object I had hoped that I could have access to the same data from outside the methods of OrgChart
.
This seems to be an unintended side effect and the data object itself is (correctly) cloned for internal use.
I need to read which nodes are expanded when I click a button in the page that is rendering my orgchart.
To do so I pass a reference to the same data object I pass to d3 and check if the
_expanded
flag is set, this gives me a value oftrue
if the node is expanded and a value ofundefined
otherwise.My issue is that for the nodes that are already visibile when the tree first renders the value is always
undefined
.If I hide all the nodes exepct the root the values are then set to
false
for all the nodes.After that if I expand again the tree the value for all nodes except the root are set to
true
when I would exepect them to, but the value for the root alwys stays onfalse
.I also tried checking the
expanded
,_children
,children
,_centered
andcentered
flags for all nodes and they always are undefined. In fact, the only property that is set when interacting with the tree is_expanded
.Is there a way that I can check with nodes are open on the orgchart at any given time?
