JavaScript进度条（datalist/repeater等多个进度条）

JS代码：

function SingleProgressBar() {
    var iload = document.getElementById("iLoading");
    var ibox = document.getElementById("iBox");
    var nowtime = new Date(getNowFormatDate());
    var deadtime = new Date($("[id$='txtDead']").val());
    var inserttime = new Date($("[id$='txtInsert']").val());
    var insert_now = Number(DateDiff("s", inserttime, nowtime).toString()); //发布日期 至 现在 的秒数
    var insert_dead = Number(DateDiff("s", inserttime, deadtime).toString()); //发布日期 至 截止日期 的秒数
    var rt = Math.round(insert_now / insert_dead * 100);
    rt = (rt <= 100) ? rt : 100;
    mySetInterval(iload, ibox, rt);
}


function ProgressBar() { //进度条
    var iload, ibox, nowtime, deadtime, inserttime, insert_now, insert_dead, rt;
    var iloads = document.getElementsByName("iLoading");
    var iboxs = document.getElementsByName("iBox");
    //ie7用document.getElementsByName不能用

        rt = (rt <= 100) ? rt : 100;
        mySetInterval(iload, ibox, rt);
    }
}

//for循环内直接使用setInterval()时，由于setInterval()执行时间有延迟
//当setInterval()执行时，for循环已经运行完毕，setInterval()只执行了一次
/*如下：在循环的时候直接调用mySetInterval()，传入参数，再进行for循环
这样就保证了每次传入的值不会在延迟time（这里即1毫秒）后而变化*/

其实当初进度条只要设个宽就行了，不需要增长效果，刚入门不知道怎么实现
