Custom action of double click on Node

I have one custom node,
when I double click on node ,we have to open one url on oneditprepare event.
I am able to open that url, but problem with edit dialog. we don't want to open edit dialog.

Node-RED doesn't provide any way to customise that behaviour. You cannot prevent the edit dialog from opening.

An alternative would be for you to set the edit pane for the node to just include a single button they click to open the url.
