If you're setting up a calendar of future events you would check that the year is the current year or greater.When setting options via HTML attributes, remember to enable the validator by setting data-fv-date="true".The time field will allow input starting with 'hh:mm' following by an optional 'am' or 'pm'. The code behind the form is as follows: For each field in the form (first the dates, then the time field), a check is made as to whether the input is blank.If not, the input is compared to the regular expression.You don't need to do that when using HTML 5 type="date" attribute (the format then will be forced to be YYYY-MM-DD).
In this example, employees will fill in a Vacation Request Form for the year 2017.
It is very important to validate the data supplied by the user through a form before you process it. In the following examples, a Java Script function is used to check a valid date format against a regular expression.
Among various kind of data validation, validation of date is one. Later we take each part of the string supplied by user (i.e.
“31/9/2010”, “31/09/2010” – September has 30 days only 10.
“31/6/2010”, “31/06/2010” -June has 30 days only 9.
