Onclicking the node change its class #147

Namaste, Is there any simple way to change the class of the node on clicking on it, maybe for highlighting the clicked node.

Thanks in advance!

Hi,

You can make your own callback for when the user clicks the node (using nodeClick). In the javascript you can for example add / change the class of the node to enable highlighting.

Best

Understood. I should use something like document.getElementById(nodeid).className = "classname"; inside nodeClick callback.

Thank you for the suggestion @ErikGartner!
