I have this code to produce a date/time picker but I only need to use the date picker element of this code.

How would do I remove the time picker element from this code and stilll have it work?

function show_calendar(str_target, str_datetime) {
var arr_months = ["January", "February", "March", "April", "May", "June",
    "July", "August", "September", "October", "November", "December"];
var week_days = ["Su", "Mo", "Tu", "We", "Th", "Fr", "Sa"];
var n_weekstart = 1; // day week starts from (normally 0 or 1)

var dt_datetime = (str_datetime == null || str_datetime =="" ?  new Date() : str2dt(str_datetime));
var dt_prev_month = new Date(dt_datetime);
dt_prev_month.setMonth(dt_datetime.getMonth()-1);
var dt_next_month = new Date(dt_datetime);
dt_next_month.setMonth(dt_datetime.getMonth()+1);
var dt_firstday = new Date(dt_datetime);
dt_firstday.setDate(1);
dt_firstday.setDate(1-(7+dt_firstday.getDay()-n_weekstart)%7);
var dt_lastday = new Date(dt_next_month);
dt_lastday.setDate(0);

var str_buffer = new String (
    "<html>\n"+
    "<head>\n"+
    "   <title>Calendar</title>\n"+
    "</head>\n"+
    "<body bgcolor=\"White\">\n"+

var dt_current_day = new Date(dt_firstday);

    dt_current_day.getMonth() == dt_firstday.getMonth()) {

    str_buffer += "<tr>\n";
    for (var n_current_wday=0; n_current_wday<7; n_current_wday++) {

This section bilds the forms but when I remover the time element out of the form it doesn’t work properly? The date picker will appear but won’t close after I remover the time picker element! How do I fix this?

str_buffer +=
    "<form name=\"cal\">\n<tr><td colspan=\"7\" bgcolor=\"#87CEFA\">"+
    "<font color=\"White\" face=\"tahoma, verdana\" size=\"2\">"+
    "Time: <input type=\"text\" name=\"time\" value=\""+dt2tmstr(dt_datetime)+
    "\" size=\"8\" maxlength=\"8\"></font></td></tr>\n</form>\n" +
    "</table>\n" +
    "</tr>\n</td>\n</table>\n" +
    "</body>\n" +
    "</html>\n";

var vWinCal = window.open("", "Calendar", 
    "width=200,height=250,status=no,resizable=yes,top=200,left=200");
vWinCal.opener = self;
var calc_doc = vWinCal.document;
calc_doc.write (str_buffer);
calc_doc.close();
}


    function str2dt (str_datetime) {     
var re_date = /^(\d+)\-(\d+)\-(\d+)\s+(\d+)\:(\d+)\:(\d+)$/;
if (!re_date.exec(str_datetime))
    return alert("Invalid Datetime format: "+ str_datetime);
return (new Date (RegExp.$3, RegExp.$2-1, RegExp.$1, RegExp.$4, RegExp.$5,    RegExp.$6));
}
function dt2dtstr (dt_datetime) {
return (new String (
    dt_datetime.getFullYear()+"/"+(dt_datetime.getMonth()+1)+"/"+dt_datetime.getDate()));
 }
 function dt2tmstr (dt_datetime) {
return (new String (
dt_datetime.getHours()+":"+dt_datetime.getMinutes()+":"+dt_datetime.getSeconds()));
