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 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.
So, I have an input field of type number:
https://www.w3schools.com/html/tryit.asp?filename=tryhtml_input_number
<input type="number" name="quantity" min="1" max="5" step = "0.01">
I would like "3." to be accepted as a valid number there. Is there a way to achieve that?
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" />
how to write pattern for input type="text" (it can't be number and the validation can't be with JS) that allow me to enter only numbers, min:1 and max:5000?
<input type="text" name="someName" id="someId" required pattern=""/>
Here you go - not an input with type="number" and no JS:
<input type="text" name="someName" id="someId" required="required"
pattern="(5000|([1-4][0-9][0-9][0-9])|([1-9][0-9][0-9])|([1-9][0-9])|[1-9])"/>
The basic pattern is to match 5000 or 4-digit number or 3-digit number or 2-digit number or non-zero 1-digit number.
If you can accept 0, the pattern can be even simpler:
(5000|([1-4]?[0-9]?[0-9]?[0-9]?))
You can use the predefined min and max attribute for input type="number" as follows,
<input type="number" min=0 max=10>
<input type="submit">
Here is an example
The error for incorrect input will be displayed when you try to submit the form
Let me know if this works :)
<input type="number">
HTML Version above!
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" />
