In my project, I need to make a default month and year which the user can't change. He should change only the date in December months. How can I do it?
<input id="input_date" type="date" maxlength="2" min="1" max="31">
min and max should be dates, not numbers. maxlength="2" is not appropriate, since dates have 10 characters.
<input id="input_date" type="date" min="2022-12-01" max="2022-12-31">
Or you could use type="number" if you just want the day of the month.
<input id="input_date" type="number" maxlength="2" min="1" max="31">

How can I force HTML time input to render hours only? I do not need to have minutes and seconds in the input.
<label for="appt">Choose a time for your meeting:</label>
<input type="time" id="appt" name="appt"
min="07:00" max="18:00" value="07:00" required>
<small>Office hours are 9am to 6pm</small>
you can use step=3600

I am creating a form that will allow a user to enter a birthday with month, day and year. For year, I am trying to write the html code such that it will only allow positive number and also limit it to 4 digits. Here is the code in question:
<input type="number" name="year" maxlength="4" max="9999" min="0" step="1" placeholder="YYYY" p="[0-9]{4}" style="color:#888;" required/>
I've scoured the web for a solution to what I am trying to do but every time I try it, it will allow me to enter a number that is greater than 4 digits... basically I am trying to limit the user to enter a valid birth year:
Any advice?? thanks in advance!!
Birth year greater than 4 digits input
thank you kennytm, your link has answered by question. I just needed to add this
onKeyPress="if(this.value.length==10) return false;
Two changes are required:
Change input type=number to type=text. This will start accepting text input without constraints.
BUT your regular expression pattern will bound text input to numbers only.
Also edit p=[0-9]{4} to pattern="[0-9]{4}".
<input type="text" name="year" maxlength="4" min="0" max="9999" step="1" placeholder="YYYY" pattern="[0-9]{4}" style="color:#888;" required/>
I'm creating a sign-up form and one of the tags require you to enter your age. You can only create an account if you're older than 18 years old. So I thought I could achieve this by adding "pattern='18-65'". But that isn't working out. Right now, you can choose any number, even negative numbers. What am I doing wrong?
<input class="required" type="number" name="age" placeholder="Age (e.g. 25)" data-type="number" pattern="18-65">
You can set min and max attributes.
<input type="number" name="age" min="18" max="65">
Use min and max attribute to define the desired range.
<input class="required" type="number" name="age" placeholder="Age (e.g. 25)" min="18" max="65" />
I have the following problem I need to exclude 0 as starting digit from number input I have the following code:
<input required type="number" min="1" value="1" id="number" name="number" pattern="[^0]d+">
but it doesn't work if the user decides to manually enter number like 01234.
To make it work change the type of the input to text and use ^[1-9]\d*$ as pattern
<input required type="text" value="1" min="1" id="number" name="number" pattern="^[1-9]\d*$">
this regex won't allow any number of starting zeros ('01', '001') nor any non-numeric characters ('1b') and accepts one digit number such as 1.
example for complete working form:
<!DOCTYPE html>
<html>
<body>
<form>
<input required type="text" value="1" min="1" id="number" name="number" pattern="^[1-9]\d*$">
<input type="submit">
</form>
</body>
</html>
<input type="number" pattern="(?!0+)\d+">
Explanation
(?!0+) # not followed by any number of zeros (negative look-ahead)
\d+ # at least one digit (by implication the first one is different from zero)
Alternative
<input type="number" pattern="[1-9]\d*">
<input type="number" maxlength="2" />
Its working in other browsers like Firefox,IE and not working in google chrome.Can any one suggest how to fix issue in chrome?
because it's a number, you can use max, not maxlength.
You need to allow only two digit number then you can use following code
<input type="number" min="1" max="99" />
Use the max attribute for inputs of type="number".
It will specify the highest possible number that you may insert
<input type="number" max="999" />
if you add both a max and a min value you can specify the range of allowed values:
<input type="number" min="1" max="999" />
For user experience, you would prefer the user not to be able to enter more than a certain number, use Javascript/jQuery.
EG: <input type="number" max="99" min="9" id="myInput"/>
$('#myinput').on('keydown', function () {
if($(this).val().length>2)
return false;
});
use max="" and there is has to be a form element for it to work otherwise it won't work.

Try this
<input type="tel" maxlength="2" />
