HTML5 pattern for formatting input box to take date mm/dd/yyyy?

Question

I used jQuery datepicker and I want to restrict my input field with a HTML5 pattern if a user, instead of getting the date from jQuery datepicker, types the date.

How can I restrict my users with a HTML5 pattern so that they can just type the date in the form mm/dd/yyyy?

Answer 1

Easiest way is use read only attribute to prevent direct user input:

 <input class="datepicker" type="text" name="date" value="" readonly />

Or you could use HTML5 validation based on pattern attribute. Date input pattern (dd/mm/yyyy or mm/dd/yyyy):

<input type="text" pattern="\d{1,2}/\d{1,2}/\d{4}" class="datepicker" name="date" value="" />

Answer 2

I use this website and this pattern do leap year validation as well.

<input type="text" pattern="(?:19|20)[0-9]{2}-(?:(?:0[1-9]|1[0-2])-(?:0[1-9]|1[0-9]|2[0-9])|(?:(?!02)(?:0[1-9]|1[0-2])-(?:30))|(?:(?:0[13578]|1[02])-31))" required />

Answer 3

pattern="[0-9]{1,2}/[0-9]{1,2}/[0-9]{4}"

This is pattern to enter the date for textbox in HTML5.
The first one[0-9]{1,2} will take only decimal number minimum 1 and maximum 2.
And other similarly.

Answer 4

Try to use:

pattern="(0?[1-9]|[12][0-9]|3[01])/(0?[1-9]|1[012])/\d{4}"

Answer 5

Below pattern perfectly works in case of leap year and as well as with normal dates. The date format is : YYYY-MM-DD

<input type="text"  placeholder="YYYY-MM-DD" pattern="(?:19|20)(?:(?:[13579][26]|[02468][048])-(?:(?:0[1-9]|1[0-2])-(?:0[1-9]|1[0-9]|2[0-9])|(?:(?!02)(?:0[1-9]|1[0-2])-(?:30))|(?:(?:0[13578]|1[02])-31))|(?:[0-9]{2}-(?:0[1-9]|1[0-2])-(?:0[1-9]|1[0-9]|2[0-8])|(?:(?!02)(?:0[1-9]|1[0-2])-(?:29|30))|(?:(?:0[13578]|1[02])-31)))" class="form-control "  name="eventDate" id="" required autofocus autocomplete="nope">
