Causes the database to run the task to have the error (the task calculates the state according to the date, because the data quantity is bigger, all makes the task to run at night), in order to avoid this kind of mistake again, therefore added a verification date validity the JavaScript method.
This method can effectively validate leap years, supported date formats are: 2009-01-01, 2009/01/01 two formats.

Determine whether the date is legal
function IsDate (otextbox) {
var regex = new RegExp ("^ (?:(?:( [0-9] {4} (-|\/) (?:(?: 0? [1,3-9]|1[0-2]) (-|\/) (?: 29|30) | ((?: 0? [13578]|1[02]) (-|\/) 31)) | ([0-9]{4} (-|\/) (?: 0?) [1-9]|1[0-2]) (-|\/) (?: 0? [1-9]|1\\d|2[0-8]) | (((?:( \\d\\d (?: 0 [48]| [2468] [048]| [13579] [26]) | (?: 0 [48]00| [2468] [048]00| [13579] [26]00)) (-|\/) 0?2 (-|\/) 29))));
var dateValue = Otextbox.value;
if (!regex.test (DateValue)) {
Alert ("Date is wrong!") ");
DateValue = "";
This.focus ();
Return
}
}
