Javascript for validating date

posted by | Leave a comment

When capturing information for insertion into a database, or use in other processing, it's important to control what the user can enter.Otherwise you can end up with values in the database that have no relation to reality.Its good practice to validate form date values using client side Java Script validation along with your programming language validation.The following example shows how you can do this for the mm/dd/yyyy format.I found this solution but it is in the wrong format for what I need, as in: (mm/dd/yyyy).Here is the link to that solution: SP/848/ My code is below: I expanded just slightly on the is Valid Date function Thorbin posted above (using a regex).We have also provided the javascript date validation for the dd/mm/yyyy format.If the valid date character is changed please make sure you replace it in the HTML and Javascript code too.

I am attempting to validate a date in this format: (yyyy-mm-dd).We use a regex to check the format (to prevent us from getting another format which would be valid for Date).After this loose check we then actually run it through the Date constructor and return true or false if it is valid within this format.When getting a date, without specifying the time zone, the result is converted to the browser's time zone.In other words: If a date/time is created in GMT (Greenwich Mean Time), the date/time will be converted to CDT (Central US Daylight Time) if a user browses from central US.
