我正在尝试在页面上进行多次倒计时,如下所示:
<table>
<tr id="4236377487">
<td class="remain"></td>
<td>Something</td>
</tr>
<tr id="768769080">
<td class="remain"></td>
<td>Something else</td>
</tr>
</table>
倒计时必须放在:
<td class="remain"><!-- countdown --></td>
每次倒计时都以行ID值开头。这是我的代码,但它不起作用:
$(document).ready(function(){
$('.remain').each(function () {
var count = $(this).attr("id");
countdown = setInterval(function(){
$(this).html(count + " seconds remaining!");
if (count == 0) {
//do something
}
count--;
}, 1000);
});
});
感谢您的帮助:)

$(document).ready(function(){
$('tr[id]').each(function () {
var $this = $(this);
var count = parseInt($this.attr("id"));
countdown = setInterval(function(){
$('.remain', $this).html(count + " seconds remaining!");
if (count-- == 0) {
//do something
clearInterval(countdown);
}
}, 1000);
});
});
