This leads to errors in database running tasks (tasks are computed based on dates, and tasks run at night due to a large amount of data). To avoid such errors, therefore, a javascript method is added to verify the validity of the date.
This method can effectively verify the leap year. Supported date formats include 2009-01-01 and 2009/01/01.
Javascript code
Copy codeThe Code is as follows:
// Determine whether the date is valid
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 (? : 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 error! ");
DateValue = "";
This. focus ();
Return;
}
}
