JS倒计时——天时分秒

HTML代码：

<div id="times_wrap"
class="time_num">

距离结束时间：

<div class="time_w">

<b id="times_d" class="time">
</b>天

<b id="times_h" class="time">
</b>时

<b id="times_m" class="time">
</b>分

<b id="times_s" class="time">
</b>秒

</div>

</div>

JavaScript代码：

<script type="text/javascript">

setTimeout("show_time()",1000);

var time_wrap = document.getElementByIdx_x("times_wrap");

var time_d = document.getElementByIdx_x("times_d");

var time_h = document.getElementByIdx_x("times_h");

// 设定结束时间
