Question

大家好我有这个非常简单的jquery计数器

    var count = 10;
  countdown = setInterval(function(){
    $("p.countdown").html(count + " seconds remaining!");
    if (count == 0) {
     alert('done');
    }
    count--;
}, 1000);

如何在它变为0后重置而不是进入减号????所以它不断迭代。

任何帮助

Answer 1

要重置并重复，请将count = 11;放在alert('done');之后。

要停止，请将clearInterval(countdown);放在alert('done');之后。

Answer 2

var count = 10,
    countdown = setInterval(function () {
        $("p.countdown").html(count + " seconds remaining!");
        if (count == 0) {
            count = 11; //since it will be reduced right after this
            //clearInterval(countdown); <-- use this if you want to stop 
            alert('done');
        }
        count--;
    }, 1000);

Answer 3

试试这个

var count = 10;
  countdown = setInterval(function(){
    $("p.countdown").html(count + " seconds remaining!");
    count--;    
    if (count == 0) {
      count = 10;
    }

}, 1000);

就像这样：

if (count == 0)
  count = 11
