var jhny = "";
var ayear = new Date().getFullYear();
var amonth = new Date().getMonth() + 1;
var adate = new Date((ayear + "-" + amonth + "-01").replace("-", "/"));
for (var z = 0; z < trs.length; z++) {
    if (trs[z].cells[7].getElementsByTagName("INPUT")[0].value != "") {
        var aadate = new Date((trs[z].cells[7].getElementsByTagName("INPUT")[0].value + "-01").replace("-", "/"));
        if (aadate < adate) {
            if (jhny == "") {
                jhny = 1;
            } else {
                jhny = jhny+","+(z+1);
            }
        }
