我一直试图让计时器在到达00:00时消失,但每当我尝试它时,它就会立即隐藏div。
以下是我正在使用的代码:
$(document).ready(function(e) {
var $worked = $("#worked");
function update() {
var myTime = $worked.html();
var ss = myTime.split(":");
var dt = new Date();
dt.setHours(0);
dt.setMinutes(ss[0]);
dt.setSeconds(ss[1]);
var dt2 = new Date(dt.valueOf() - 1000);
var temp = dt2.toTimeString().split(" ");
var ts = temp[0].split(":");
$worked.html(ts[1] + ":" + ts[2]);
setTimeout(update, 1000);
}
setTimeout(update, 1000);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="worked">00:10</div>

我为你创造了一个例子。在本例中,我将计时器的间隔更改为10毫秒,以便您可以更快地查看结果。另外,不要在setTimeout
函数中设置update
以运行update
。您可以使用setInterval
。我还在更新函数中添加了一个检查,检查时间是否为00:00
。如果是,则通过调用clearInterval(timer);
并运行$worked.hide()
$(document).ready(function (e) {
var $worked = $("#worked");
var timer = setInterval(update, 10);
function update() {
var myTime = $worked.html();
var ss = myTime.split(":");
var dt = new Date();
dt.setHours(0);
dt.setMinutes(ss[0]);
dt.setSeconds(ss[1]);
var dt2 = new Date(dt.valueOf() - 1000);
var temp = dt2.toTimeString().split(" ");
var ts = temp[0].split(":");
$worked.html(ts[1]+":"+ts[2]);
$worked.html(ts[1]+":"+ts[2]);
if(ts[1] === '00' && ts[2] === '00') {
clearInterval(timer);
$worked.hide();
}
}
});

这是另一种方法:)
$(document).ready(function(e) {
var $worked = $("#timer");
var startTime = new Date().getTime();
var now, currentDistance;
setInterval(function update() {
now = new Date().getTime();
currentDistance = 10000 - now + startTime;
if (currentDistance > 0) {
$worked.html(parseInt(currentDistance / 1000) + " seconds, " + (currentDistance % 1000) + " ms left!");
} else {
$worked.hide();
}
}, 1);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="timer" style="background-color: rgb(190, 190, 220); width: 200px; text-align: center"></div>
