问题描述：
我现在想做个倒计时。单独一个拍品，我做的出来，可是一个页面多个调用同一个javascript，就不显示时间了？我现在很烦，我把代码贴出来
<script language="javascript">
var _t;
var _h = <%=h%>;
var _m =<%=m%>;
var _s = <%=t%>;
var _v = formatTime(_h + ':' + _m + ':' + _s);
function doTime() {
_s --;
if (_s == -1) {
_m --;
_s = 59;
}
if (_m == -1) {
_h --;
_m = 59;
}
var _b = ((_h == 0) && (_m == 0) && (_s == 0));
if (_b) {
_v = 'Welcome';
clearTimeout(_t);
} else {
_v = formatTime(_h + ':' + _m + ':' + _s);
_t = setTimeout('doTime()', 1000);
}
document.all['oTime'].innerHTML = _v;
}
function formatTime(_time) {
return _time.replace(/(w)/g, '0$1');
}
onload = function() {
document.all['oTime'].innerHTML = _v;
_t = setTimeout('doTime()', 1000);
}
</script>
显示的时候调用<span id="oTime"></span>
我用的rs.movenext多个显示的，就没有用了！~单独就可以
