问题
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?
回答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="" />

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 />
回答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.

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

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">
