Is it possible to add an action in response to a double click (distinct from single click) to a plain ui-button?

I also have the same question about a ui-list element.

Thanks for any help, pointers ...

It might be able to work with an input from a `ui_button` as well?? Test and see.

Hi @Gunner,  
I wrote that node for physical buttons, e.g. read via a GPIO pin. Seems that this question is about double clicks on a ui-button in the dashboard.  
I assume double clicks events are not handled at the moment? Have to leave for work (first day in 1,5 year not working from home) so cannot quickly test...

Not that I have implemented [recently](https://discourse.nodered.org/t/node-red-contrib-ui-svg-click-and-dblclick-in-same-element/50203) something similar in svg.

Yes, I did see that, but figured an input trigger is an input trigger.... but then later realized, as I was testing, that a `ui_button`, while visually acting like it would, doesn't seem to have an option for triggering on a "release"... which, belatedly, seems _ **a very strange omission** _ as it could otherwise easily be used as a "proper" multi-click button.

I have experimented with faked a release using a timed 0 inject, and that works for some of your node options, but getting the timing just right for a click or double click is a bit more difficult.

Actually, it doesn't trigger on the "press", rather it _ **triggers on the "release"** _... strange that I never noted that before. It clearly detects the press visually, so why not trigger on both?

I did some searching before posting but almost everything that turned up seemed aimed at physical buttons. The only one related to a dashboard button (which you linked above earlier) seemed a bit flakey - author still working on detecting a single press vs the 4 he had achieved already.

If a double click isn't built into the ui-button (from replies so far I'm assuming it's not) I was hoping it could be done fairly easily with perhaps a function node following the ui-button and doing some sort of timing of successive clicks passed to it. I had a quick go at that myself but my node-red skills are still quite young so unsuccessful so far. I was hoping this was such an obvious need that someone had already implemented something or other.

I thought there was a multi-press dashboard node that someone had contributed, but I can't find it on the flows site. It did single, double, long press. Possibly more.

Here is something I got working using @BartButenaers `contrib-button-events` with `ui_button`

Since the button only triggers a **1** on release, the delay and function send a **0** 50ms after, thus the button event node just gets the expected 1/0 pulse. I turned off debounce in that node.

And right after that... I saw a post by @UnborN that simply creates a dashboard button with proper press and release 👍

I have added that to my flow... no need for the timer for that button 😃

Thanks for that [Gunner](https://discourse.nodered.org/u/Gunner)- easily modified to detect click & dblclick events.

Also a good demo for node-red noob like me on how to use template node with javascript for ui elements.

Thanks for the example [E1cid](https://discourse.nodered.org/u/E1cid). It's good in that it detects double click just fine; however it doesn't signal single click. Simply modifying the function node to generate a second output for single clicks (anything not a double click) doesn't work because (I guess) the first click of a double is also interpreted as a single click on its own.

Great! Works with trigger node added. I'll mark this one as the solution because it works using the ui-button node as originally requested.

Hmmm... After a few failed attempts of my own, I had actually tried the flow from @E1cid before I had made the one I posted above. But couldn't get anything but a **"1"** out of it.

Same with this last one... What gives? I am clicking fast, clicking slow, clicking with and without looking, I think I tried once with my forehead... but that might have been counter-productive 😛

**EDIT**... ahhh forget it... I was looking at the payload, not the payload's node of source.

I fixed that 😉

Just for info

I found that it was slightly unstable with repeated operations in quick sucsession, So I did the context storage with a change node, this seems more stable. Seems the change node is faster at context storage than the function node.

Able to lower the delay to 300 ms with the change node.  
[edit]  
here it is in series so no cloning msg

First time used will set context, then functions as normal
