destoon开发笔记-JQ+JS实现倒计时功能

页面代码

<div class="time "  class=""  id="onBidtime125" pid="125">
    <div class="timeicon" ></div>
        距离结束：<span class="day">-</span> 天 <span class="hour">-</span> 小时 <span class="minute">-</span> 分 <span class="second">-</span> 秒
        <script type="text/javascript">
            $(function(){
                endDown2("1472287680","1470660651","#onBidtime125","#onBidtime125 .day","#onBidtime125 .hour","#onBidtime125 .minute","#onBidtime125 .second");
            });
        </script>
</div>
