I am new to node red, and I am trying to determine the mechanism (if any) for applying client-side javascript to run with/against the form. I have seen places with examples of jquery with a custom nodes forms, but have been unable to figure out how to apply this through the html piece of the node or some other place. Thanks guys

Hi @justin
The docs cover the node's html file: [https://nodered.org/docs/creating-nodes/node-html](https://nodered.org/docs/creating-nodes/node-html)
You can use the `oneditprepare` and `oneditsave` functions in the node's definition to trigger any custom behaviour you want in the edit dialog.
