comparing times in javascript???

I need to be able to only allow my clients to enter data into a part
of a form between specific hours of the day. i can find tons of
articles on comparing dates, but not times. does anyone know how to
do this?

this is what i came up with, but its obviously not right. thanks in
advance

var a_p = "";
var d = new Date();

var curr_hour = d.getHours();

if (curr_hour < 12)
{
a_p = "AM";
}
else
{
a_p = "PM";
}
if (curr_hour == 0)
{
curr_hour = 12;
}
if (curr_hour 12)
{
curr_hour = curr_hour - 12;
}

var curr_min = d.getMinutes();

curr_min = curr_min + "";

if (curr_min.length == 1)
{
curr_min = "0" + curr_min;
}

var curr_time = curr_hour +":"+curr_min+" "+a_p;
alert(curr_time);




if (curr_time '8:59 AM' ) && (curr_time < '1:01 PM' ) {


alert("ok");
} else {


alert("nope");
}

re: comparing times in javascript???

All that is much too complex. What does the comparison operator know about
AM and PM?

Get the current hour and minute (as you said) and calculate
60*hour+minutes. Compare that to the start and end times in minutes past
previous midnight (=0).

Be sure to account for local/GMT time with the time function.

There is no need for the limitation to 60 minutes in every hour! This
form allows times to be entered as normal un-separated 24-hour clock
figures. It assumes that the OP's "between" means "between"; possibly
one or other bound should really be inclusive.

Perhaps the OP did not try a search for javascript "time comparison" .

On the Web, users are not necessarily local, and it may be better to
work in UTC.

Using AM & PM in data processing is sheer folly.

It's a good idea to read the newsgroup c.l.j and its FAQ. See below.

That is nice.
You get first few hits. ;)
That up to the OP -- the requirement might be local or otherewise.
Definitely
