var pattern =/^ (((1[6-9]|[ 2-9]\d) \d{2})-(0?[ 13578]|1[02])-(0?[ 1-9]| [12]\d|3[01]) | (((1[6-9]| [2-9]\d) \d{2})-(0?[ 13456789]|1[012])-(0?[ 1-9]| [12]\d|30)] | (((1[6-9]| [2-9]\d) \d{2}) -0?2-(0?[ 1-9]|1\D|2[0-8]) | (((1[6-9]| [2-9]\d) (0[48]|[ 2468][048]| [13579] [26]) | ((16| [2468] [048]| [3579] [26]) 00)) $/ -0?2-29-))
if (!pattern.test (Document.form1.pro_date.value)) {
Alert (the "date format is not correct, please re-enter!");
Document.form1.pro_date.focus ();
Document.form1.pro_date.select ();
return (false);
Put this code in your function and you can use it directly.
