How to get the data of a node in d3
In my previous article on enter, update and exit selections, I discussed how d3 binds data to nodes using the data()
function. How about the inverse case where you have a reference to a node to which data is supposedly bound and you want to get the value of that data.
Take another case - when you have a reference to a node, but you want to access the data that is bound to a parent node.
Turns out, you can easily get the data bound to a node as follows
d3.select(your_node).datum();
your_node
is a reference to the actual DOM node.
