Updates
- support touch screen events (touchstart, touchend)
- fixed the repeater button getting stuck
- making a button blink (CSS) (by adding/removing a class via a node-red msg)
- disabling/enabling a button (CSS) (by adding/removing a class via a node-red msg)
- repeater buttons that can send an event on release.
- adding a maximum limit "send count" for repeater buttons (i.e. limit the number of repeat events)
Demo 1 - making a button disabled or blink by sending a msg
Demo 2 - limiting a repeat button and firing on release (pay attention to the .event propetry in the debug - you can use msg.event this to understand if a msg is an "down" or "up"
notes...
-
two new attributes added
-
data-max(optional) - set this to a number to limit how many times a repeater can repeat (see the vol+ button) -
data-fireonup(optional) - set this to="true"to have an "up" event fired when you release a "repeater" button
-
-
I had to add some classes for
blinkinganddisabling(checkout the CSS template node) -
you are NOT limited to "blinking" or "disabled"
- Now that you have the ability to
addclass,removeClass,toggleClass- the sky is your limit. - want to make a button spin on demand? add a class to your CSS that spins a button, then use
toggleClassto turn it on or off - want to make a button disappear on demand? add a class to your CSS that sets
display:none, then usetoggleClassto turn it on or off
- Now that you have the ability to
updated flow...
