我有一个基本日历，我从这里获得http://www.dynamicdrive.com/dynamicindex7/basiccalendar_dev.htm
我想通过添加一个svg图像来仅修改其中包含日期的单元格来修改日历。日历操作只有具有日期的单元格
我评论了JavaScript中我认为需要操作的行。它是从底部开始的第五条线。我尝试在该行的'td'中添加一个Id，但是这影响了它们中没有日期的单元格。
需要做些什么来隔离其中包含日期的单元格？有任何想法吗？感谢任何帮助。
的JavaScript
var todaydate = new Date()
var curmonth = todaydate.getMonth() + 1 //get current month (1-12)
var prevmonth = todaydate.getMonth() - 1 //get current month (1-12)
var curyear = todaydate.getFullYear() //get current year
document.write(buildCal(curmonth, curyear, "main", "month", "daysofweek", "days", 1));
function buildCal(m, y, cM, cH, cDW, cD, brdr) {
var mn = ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'];
var dim = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31];
var oD = new Date(y, m - 1, 1); //DD replaced line to fix date bug when current day is 31st
oD.od = oD.getDay() + 1; //DD replaced line to fix date bug when current day is 31st
var todaydate = new Date() //DD added
var scanfortoday = (y == todaydate.getFullYear() && m == todaydate.getMonth() + 1) ? todaydate.getDate() : 0 //DD added
dim[1] = (((oD.getFullYear() % 100 != 0) && (oD.getFullYear() % 4 == 0)) || (oD.getFullYear() % 400 == 0)) ? 29 : 28;
var t = '<div class="' + cM + '"><table class="' + cM + '" cols="7" cellpadding="0" border="' + brdr + '" cellspacing="0"><tr align="center">';
t += '<td colspan="7" align="center" class="' + cH + '">' + mn[m - 1] + ' - ' + y + '</td></tr><tr align="center">';
for (s = 0; s < 7; s++) t += '<td class="' + cDW + '">' + "SMTWTFS".substr(s, 1) + '</td>';
t += '</tr><tr align="center">';
for (i = 1; i <= 42; i++) {
var x = ((i - oD.od >= 0) && (i - oD.od < dim[m - 1])) ? i - oD.od + 1 : ' ';
if (x == scanfortoday) //DD added
x = '<span id="today">' + x + '</span>' //DD added
t += '<td id="CellDate" class="' + cD + '" >' + x + '</td>';//// this is where the date values appear in the cells, this is where we need to insert the svg
if (((i) % 7 == 0) && (i < 36)) t += '</tr><tr align="center" >';
}
return t += '</tr></table></div>';
