简单的jquery计数器

Question

大家好，我有一个非常简单的 jquery 计数器，

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

我怎样才能让它在达到 0 后重置而不是进入负数？？？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

试试这个

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

}, 1000);

Answer 3

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 4

就像这样：

if (count == 0)
  count = 11
