I want an input that it can only enter exactly N quantity of numbers , no less, no more.
I have tried this:
Example with 4 digits.
<input type="text" name="myinput" pattern="[0-9]{4}" title="Only four (4) digits.">
But it does not work, someone knows how to fix it?
By "it does not work" I assume you mean the pattern isn't checked when the input is empty. Otherwise there doesn't seem to be anything wrong with the pattern.
That is how the pattern attribute works. You'll have to add required as well if you don't want to allow empty input.
<form>
<input type="text" name="myinput" pattern="[0-9]{4}" required>
<button type="submit">Submit</button>
</form>

So I'm trying to make a form for my assignment, and I am using the pattern attribute in html so only certain characters are required to be typed on the text box. But for some reason, the form is saying using that I'm using an incorrect format even though I made my pattern attribute that way.
Here's an example of the code and a picture of the problem.
<form>
<label for="mnumber">Mobile Number:</label>
<input type="text" required id="mnumber" pattern="[0-9]"><br><br>
<input type="submit" value="submit">
</form>
You did write:
pattern="[0-9]"
You are asking for only one number. You just forget to add '+' to accept more than one number. I guess what you are searching for is this:
pattern="[0-9]+"
pattern="[0-9]"
allows for only a single number character to validate (and be submitted). If you want to allow more than one character, here's your options:
One or more numbers:
pattern="[0-9]+"
Zero or more numbers:
pattern="[0-9]*"
One to three numbers:
pattern="[0-9]{1,3}"
you just need to change type="text" to type="number"
I have a field input with type number in my form I would like to allow exact 13 characters to that field no less no more as per the requirement. I wanted to know is there any by default option in HTML using which I can accomplish this? I tried pattern and maxlength but for some reason they are ineffective with the type number. If it is not possible from HTML side then I would like to achieve the same using the angularjs. Any inputs would be really useful.
<input type="number" id="userCode" ng-model="formdata.userCode" title="13 Digit code"></input>
As per the below answer I added the min and max as 13. After adding it when I enter even 13 digits then also I get the error. Can someone please let me know what am I doing wrong here?
<input type="number" min="13" max="13" id="userCode" ng-model="formdata.userCode" placeholder="Enter 13 Digit Code" title="Please Enter the 13 digit code" class="form-control" style="width: 200px;" ng-required="true">
<form action="">
<input type="text" required pattern="[0-9]{13}" maxlength=13 id="userCode" ng-model="formdata.userCode" title="13 Digit code">
<input type="submit">
</form>
You can check here for some other attributes of input to play around with.
If anyone is looking they can also check this answer:
<input type="text" pattern=".{13,13}" oninput="this.value=this.value.replace(/[^0-9]/g,''); title="13 characters length required" ">
With this input field although its text we can make sure that it accepts only the numbers.
Just trying to make a field that only accepts 8-digit numbers and every browser lets it pass with any number of digits.
<form>
<input type="number" pattern="[0-9]{8}" required>
<input type="submit">
</form>
I feel like I'm missing something really obvious here am not seeing the problem with my pattern.

<input type="number"> elements do not support use of the pattern attribute for making entered values conform to a specific regex pattern.

My Html input type number is not accepting 0 as a first input. It only accept 1 to 9 digit as a first input. Here is my code
<input type="number" class="form-control" name="signup_phone" id="signup_phone" placeholder="<?php esc_html_e('Phone', 'service-finder'); ?>">
If i give input 120124214 it accept. But if I give 0124452 it is not taking my input.
Use this simple code
<input type="tel" pattern="[0-9]*">
What browser are you using? Works fine for me. Test it here.
function validate(){
alert(document.forms[0].signup_phone.value);
}
<form onsubmit="return validate()">
<input type="number" class="form-control" name="signup_phone" id="signup_phone" placeholder="something">
<input type="submit">
</form>
This might be an issue with phone number validation. See this SO answer.
NANP numbers take the form NXX NXX XXXX where N is a digit 2-9 and X is a digit 0-9. Additionally, area codes and exchanges may not take the form N11 (end with two ones) to avoid confusion with special services except numbers in a non-geographic area code (800, 888, 877, 866, 855, 900) may have a N11 exchange.
To achieve expected result, use below option
<input type="text" onkeypress="return event.charCode === 0 || /\d/.test(String.fromCharCode(event.charCode));">

I want my input box to only allow 4 numbers (not characters).
I have tried a few different solutions on stackoverflow but none of them seem to work for me.
You can limit the amount entered by characters but not by numbers.
So far i have tried:
maxlength="4" pattern=".{4}"
and
maxlength="4" pattern="([0-9]|[0-9]|[0-9]|[0-9])"
which none of those work for me.
Anyone any idea how to achieve this?
Try input type = "number" and give the min and max value as following:
<input type="number" name="quantity" min="0" max="9999">
HTML-5 Input Type Number
its working for me just re-checked on fiddle.
<input type="text" id="83filename" maxlength="2" />
