I know we can restrict the user to enter numbers less than specific max number by below code.
<input id="txt" max="9999" type="number">
If user enters anything more than 9999 a tooltip will appear above textbox asking user to enter number less than 9999. Is there way to restrict user to enter only max 4 numbers in textbox. System will not allow numbers enter any thing in text box after 4 digits are entered.
This is working with normal texbox using below code but for numeric textbox, system allows to enter n digits.
<input id="txt" maxlength="4" type="text">
P.S. I have already done validation using Jquery, if user enters more than 4 digits, system will notify users. My requirement is user should not be allowed to enter 5th digit at all.
You can use Jquery
$("#txt").blur(function() {
if ($('#txt').length > 4) {
$('#txt').before('your notice');
}
});

For a number input, is there a way to have step=1 yet allow the user to enter decimal numbers?
The reason is I want the arrows on the input box to increase/decrease the value by 1, but allow the user to enter decimals if they want to be more specific.
At the moment I have:
<input type="number" name="price" placeholder="£" step="1" id="id_price">
The arrows work as intended, but I get a validation error if 2.99 is entered, for example. Removing the step allows decimals to be entered, but the arrows now only increase/decrease by 0.01.
I am leaning towards a Javascript solution, but I was just wondering what the best solution was. Is there another option or an existing library?
<input type="number" step="any"> step any allow user to enter decimal too and increase by 1.
I'm working with angular 4.3, I have an input field with input type number. I'm trying to restrict the user from entering any characters/letters. However, input type number is not fully supported and allows me to enter characters such as "ABCDEFG" within the input field. What would be the best approach to restrict letters?
<input type="number"/>
If number doesn't work, I usually suggest to go for <input type="text" pattern="\d+"/>.
You can of course change your pattern to anything number-related (like (\d|[1-5]\d|60) to set min to 0 and max to 60)
I have an application whereby a user has to input a minimum of 15 digits in a number type textbox.
If a user enters a longer number, sometimes >= 19 digits, and then either uses the arrows on the right or the arrow keys on their keyboard, it autoformats the number to a float with e+ at the end which, obviously, isn't ideal.
<input min="0" type="number" value="7897894561234567898">
What's the best way to either remove or counteract this behaviour? Is there anything to be done, or will I have to use a text type input? (I'd rather not).
The HTML5 <input type=number> specifically uses the same Number type as JavaScript. The maximum integer value before precision is lost is 9007199254740991, which has 16 digits.
You can't handle larger integers than that as a Number in JavaScript, you have to treat it as a string.
You should use <input type=text>, along with a pattern attribute for validation, and an inputmode attribute for touchscreens. The default validation message is not useful, so the 'invalid' event should also be handled.
(Just kidding, inputmode isn't supported anywhere. You should use <input type=tel> to show a numeric keyboard on touchscreen devices.)
<form>
<input name=num type=tel
required pattern="\d+"
oninvalid="setCustomValidity('A number is required')"
oninput="setCustomValidity('')">
<input type=submit>
</form>
There's a note in the spec about credit card numbers:
The type=number state is not appropriate for input that happens to only consist of numbers but isn't strictly speaking a number. For example, it would be inappropriate for credit card numbers or US postal codes. A simple way of determining whether to use type=number is to consider whether it would make sense for the input control to have a spinbox interface (e.g. with "up" and "down" arrows).
See: https://html.spec.whatwg.org/multipage/input.html#number-state-(type=number)
I've few doubts/huddles for my page
1). I've a input control. It should only allow user to enter between 1 to 5. If user tries to enter maximum of 5, error should be thrown.
will ng-pattern="/^[1-5]*$/" correct?
<input type="text" ng-model="MovieRating" class="form-control" name="MovRate" ng-pattern="/^[1-5]*$/" required />
<span ng-show="adduserform.MovClafictn.$error.pattern" class="spnmsg">Rating should be 1 to 5</span>
2)Have one more input control which should be entered 4 digits only. Less than that/More of it should trigger validation. (Actually this control for entering year value)
ng-pattern="/^\d{5}$/"
This will allow user to enter only 5 digit number.
You can also make use of ng-maxlength as well for specifying the length and input type="number" for allowing only numbers.
Similarly if you want to allow only between 1 to 5, then set min="1" max="5" in your input type="number"
Regarding valid year:
ng-pattern = "/19[789]\d|20[01]\d/g"
This will allow from 1979 to to 2019
Else even simple ng-pattern = "^(19|20)\d{2}$" will match from 1900 to 2099
I want to prevent the user from entering non-numeric characters in a textfield for telephone number in HTML5. I tried this, but it doesn't forbid non-numeric characters:
<input type="tel" name="usrtel"><br>
I tried using type=number as well, but that gives me a up and a down arrow to increase or decrease the value, which is not useful for telephone numbers. How can I accomplish this?
You can use pattern attribute with a regex \d*
<input type="tel" name="usrtel" pattern="\d*" />
Demo (After typing in the box, just click anywhere outside the box, if you type in anything except the integers, it will show a red box, else it will stay normal)
Demo 2 (With custom message and submit button)
As you commented, you can change your pattern value to ^[0-9]{3,45}$ where user will have to input minimal of 3 digits to maximum of 45 in length.
Demo
<input
type="tel"
name="usrtel"
pattern="^[0-9]{3,45}$"
title="You can only enter numbers, with a minimal of 3 characters
upto 45 characters are accepted."
required="required"
/>
In the above markup, am using a title which will throw a custom error to your user.
