JS计时器未重置

Question

Stopwatch resets, since clicking start again stop watch begins the counting at zero. However, I would like to show zero out as well, similar to when the page is first refreshed. Any ideas?

https://jsfiddle.net/xmp5fq50/

var Stopwatch = function(elem, options) {
var timer = createTimer(),
startButton = createButton("Start", start, "start"),
stopButton = createButton("Stop", stop, "stop"),
resetButton = createButton("Reset", reset, "reset"),
offset,
clock,
interval;

If you are looking for it to go back to it's original state then you can simply remove render(0) from the reset function and replace with timer.innerHTML = ''; This is possible since you are simply just needing to reset to starting state which would be an empty span.

If you wanted to reset to 0 and display that then you could do timer.innerHTML = '0.0'; instead so that the span resets to a 0 state rather than hiding it.

The resulting function would look something like:

function reset() {
    clock = 0;
    timer.innerHTML = '0.0';
}

I have adjusted the JSFiddle to show you.
