Javascript implements promotion countdown fixed at the bottom_javascript skills

复制代码 代码如下:

<script> <br><br>var djs = function(d,o) <br>{ <br>var f = { <br>zero: function(n){ <br>var n = parseInt(n, 10); <br>if(n > 0) { <br>if(n <= 9) n = '0' n; <BR>return String(n); <BR>} else { <BR>return '00'; <BR>} <BR>}, <BR>run: function(){ <BR>var ts = Math.round((new Date(d).getTime() - new Date().getTime()) / 1000); <BR>if(o && ts > 0) <br>{ <br>var yy = Math.floor(ts / 31556926); <br>var mm = Math.floor(ts / 2629744); mm = mm > 0 ? mm : '00'; <br>var dd = Math.floor(ts / 86400); dd = dd > 0 ? dd0 : '00'; <br>var hh = Math.floor(ts / 3600); hh = hh > 0 ? hh$ : '00'; <br>var ii = Math.floor(ts / 60); ii = ii > 0 ? ii` : '00'; <br>var ss = Math.floor(ts % 60); <br><br>if(o.y) o.y.innerHTML = f.zero(yy); <br>if(o.m) o.m.innerHTML = f.zero(mm); <br>if(o.d) o.d.innerHTML = f.zero(dd); <br>if(o.h) o.h.innerHTML = f.zero(hh); <br>if(o.i) o.i.innerHTML = f.zero(ii); <br>if(o.s) o.s.innerHTML = f.zero(ss); <br>} <br><br>window.setTimeout(f.run,1000); <br>} <br>} <br><br>f.run(); <br>} <br><br>function ieFixed(id) <br>{ <br>var isIE = (document.all) ? true : false; <br>var isIE6 = isIE && ([/MSIE (d).0/i.exec(navigator.userAgent)][0][1] == 6); <br>var obj = document.getElementById(id).style; <br>if (isIE6 && obj) <br>{ <br>obj.position = "absolute"; <br>obj.bottom = "0px"; <br>obj.right = "0px"; <br>var tm = window.setInterval(function(){ <br>obj.marginBottom = "0px"; <br>obj.left = ( document.documentElement.scrollLeft document.documentElement.clientWidth - 312) "px"; <br>}, 80); <br>} <br>} <br></script>

<script> <br>var d = new Date().getTime() 3600*24*1000; <br>var d = 1379572933131; <br>var o = { <br>d: document.getElementById('day'), <br>h: document.getElementById('hour'), <br>i: document.getElementById('min'), <br>s: document.getElementById('sec') <br>} <br>djs(d,o);//倒计时 <br><br>ieFixed('lefttime3'); //固定在底部 <br></script>

1）兼容IE6
2）自动倒计时，输入的数字必须是时间，单位毫秒。
