Question

我有一个段落,希望把第二段放在这个时间上:

传真:

<p>xx seconds remaining</p>

Java:

window.setInterval(retrieveLog, 20000);

我如何能够这样做?

Answer 1

当你打电话时,储存时间:

var end = (new Date).getTime() + 20000 * 1000; // current time in ms since 1/1/1970, plus the interval time
window.setInterval(retrieveLog, 20000);

并添加一个更新案文的间隔:

var interval = setInterval(function() {
    var now = (new Date).getTime();
    $("p").text(Math.floor(( end - now ) / 1000));
    if(now > end) clearInterval(interval);
}, 1000);
