或许你还记得google邮箱不停增加的MB数量吧。

下面的代码可以实现类似功能，实现很简单（或许应该去掉abs重写一下，只有增长没有减少的数值感觉有点假了。）

代码结构如下：

    <div class="value"><span id="dispnum6">8,344,618</span></div>
  </li>
</ul>

</html>

JS脚本如下：

function formatNumber(number, decimals, dec_point, thousands_sep ) {
 var n = number, c = isNaN(decimals = Math.abs(decimals)) ? 2 : decimals;
 var d = dec_point == undefined ? "," : dec_point;
 var t = thousands_sep == undefined ? "." : thousands_sep, s = n < 0 ? "-" : "";
 var i = parseInt(n = Math.abs(+n || 0).toFixed(c)) + "", j = (j = i.length) > 3 ? j % 3 : 0;
 return s + (j ? i.substr(0, j) + t : "") + i.substr(j).replace(/(\d{3})(?=\d)/g, "$1" + t) + (c ? d + Math.abs(n - i).toFixed(c).slice(2) : "");
}

var ttnum=3567066;var tt;function dis_num() { document.getElementById ("dispnum").innerHTML=formatNumber(ttnum, 0, '.', ','); ttnum	= ttnum+2; tt = setTimeout ("dis_num()",800);	} dis_num();
