Code snippet to start stopwatch
开始秒表的代码片段
Initially the position of stopwatch is zero. Clicking on the “Start” button fetches the current time and invokes the Counter() method, which counts the difference between the current and the start time. ”setTimeout()” is a callback method used for calling the Counter() in every 10 milliseconds.
秒表的最初位置是0。单击"开始"按钮,获取当前时间并调用Counter()方法,计算当前和开始时间的差异。setTimeout()是一个回调函数,用于每10毫秒调用Counter()函数。
function Start() {
       startTime
= tizen.time.getCurrentDateTime();

Counter();

...}//code snippet for counter

function Counter() {

var duration = tizen.time.getCurrentDateTime().difference(startTime);

Refresh = setTimeout('Counter()',10);

Time_format(duration.length + Diff);

...}

Code snippet to stop stopwatch
停止秒表代码片段
After clicking on the “Stop” button, the counter stops and shows the difference between the stop and the start time. ”clearTimeout()” method is used to clear the interval.
单击"停止"按钮,计数器停止,并显示差异时间。
function Stop() {
       clearTimeout
(Refresh);

var duration = tizen.time.getCurrentDateTime().difference(startTime);

Diff += duration.length;

...}
