@KJ Good point. Function checkDate can use additional checks for validity of “y” parameter (value being numeric and within specific range). Please feel free to post an updated function here so others could benefit

Thanks Yuriy, but you do not have any year checks? 01/01/9999 or 01/01/mmmm which translates to 01/01/0 pass your edit checks.

@Ciao, unfortunately doesn’t seem to work universally. For example in IE

isFinite(Date.parse(’58/79/2011′))

returns true.

There is a simpler way….

var isDateOrNot = isFinite(Date.parse(myString));

@Chakri Should be pretty straightforward, replace "/" with "-" and month number with string representation.

Thanks.. and now i am getting the locale format by using jQuery.. here i have one query like now i am going to validate the format like dd/mm/yyyy or mm/dd/yyy for this i was done the following changes

if (da == “dd/MM/yyyy”)
iResultCode = checkDate(aD[1], aD[0], aD[2])
else
iResultCode = checkDate(aD[0], aD[1], aD[2])

and i was change the checkDate(y, m, d) to checkDate(d, m, y)

i am getting aD[o]=date, 1=month, 2=year if it is //dd/mm/yyyy

based on this format i was change the aD[] array values..

But it’s not works for correct date also it shows wrong format.. i am not sure where i done the mistake.. can you please help me, how to i resolve this?

@Chakri As far as I know there's no client-side detection of the locale, but if I find out a way I will post it here.

with out any server side code we can’t find the locale date format inside the script? If you have any idea please let me know..
