How to catch when a user releases a bbUI slider?

I'm a bit stumped on how I can catch when a user releases a slider control.  What I'm trying to do is call a webservice and update the resultset only when the user moves the slider to the desired value and releases the control.  I'm trying to avoid having a go button (the UI/UX guy at my day job would smack me).  I'm handling the onclick event to update the number to the right, but it doesn't seem like any other events are supported; I've tried ontouchend, onmouseup and a few others, but they don't seem to be handled.  Any ideas?

Re: How to catch when a user releases a bbUI slider?

Right now there isn't an "onendinteraction" event that you would be able to subscribe to on a slider.  We implemented just the standard HTML5 slider events into the control

 

What you could do is in the onchange of the control start a timer with a threshold to see if the user is still interacting with the control.

 

Pseudo code would look something like the following (CODE MAY NOT EXECUTE, EXAMPLE ONLY)

 

var myTimer;

function myonchange() {
    if (myTimer) {
      window.clearTimeout(myTimer);
    } 
    myTimer = window.setTimeout(myTimerResult, 1500); // Wait 1.5sec since last change
}

function myTimerResult() {
myTimer = undefined;
// Do what you need, user is done interacting }

That works.  I had actually tried doing a setTimout, but I didn't do a clearTimeout, which is what I was missing.

 

Thanks Tim!
