HTML input[type=number] : override arrow behaviour - html

Is it possible to have an input element with type equal to number, whose arrow buttons would change the value not by step attribute, but by other given number?
I need to have a field with step equal to .001, buy I'd like to make +-1 jumps by clicking arrows. (I ask aboout native arrow buttons, of course I can simulate them anyhow, but that's not the question.)

googling turned this up first
<input type="number" name="points" min="0" max="100" step="0.001" value="30">
Other than that, I guess you'll need to use JS to manipulate the behaviour. Maybe sth like:
<input id="example" type="number" name="points" step="0.001" onchange="checkChangedInput();">
<script>
function checkChangedInput() {
// check if number got lower or higher
...
document.getElementById("example").value += OldValuePlusZeroPointNineNineNine;
</script>
Though I guess using onchange might give unexpected results when sth is being typed in the field. So you should also check if in/decrement was more than your step(0.001).
This might yield some useful information as well: HTML5 input type=number change step behavior

HTML number input: how to allow decimal numbers with step=1

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.

Changed value doesn't detect by up and down arrow of type="number"

I didn't do too much but up and down arrow doesn't detect the changes when we type number manually it bind with totalQuantity but if we tries to use down or up arrow which is inside input box, it doesn't detect that value is changed. It shows me previous value
<input type="number" name="quantity" [(ngModel)]="totalQuantity" />
Can you check this in stackblitz.

HTML Input remove last char letter spacing

I have a HTML input with maxlength=4 attribute on it and it works well.
The thing is when I type the last character - it hides the first one while i'm focused on the input. when I lose focus (blur) the inputs looks ok.
Here's a visual explanation:
While typing:
When I get to 4 it looks like this (1 is hidden):
When I lose focus:
Here is my HTML input:
<input name="input[input-1]" type="text" maxlength="4" style="letter-spacing:15px;" class="numeric">
How can I fix this?
provide your html css code here. if you are using type="number" and a fixed width it might be for the reserved place in type number for the increment and decrement arrows.
i can't see any problem here :
<input type="number" min="1" max="9999" value="1">

Change the Increment Value of HTML Number Input - Decimals

Is there any way to change how much a number is incremented when using the up/down arrows on a HTML number input form?
<input type="number" step="any" value="0.00000000"></input>
I'm working with tiny numbers, it would be nice if the up/down arrows incremented just 0.00000001 at a time, instead of a whole number.
0.00000000
0.00000001
0.00000002
0.00000003
Instead of
0.00000000
1
2
3
I doubt very much if there is an easy way to do this, just though I'd ask and see if anyone else has a workaround or method as I'm sure many people experience a similar issue.
Thanks,
The step attribute is for this. Your code now has the value any, which means that any values are accepted and the step size is the default, 1. Replace it by a specific number to set the granularity and the step size. Example:
<input type="number" step="0.00000001" value="0.00000000">
Note: The end tag </input> is invalid in HTML syntax for HTML5. In XHTML syntax it is allowed, but “self-closing tags” are recommended instead of it, e.g. <input type="number" step="0.00000001" value="0.00000000" />.

HTML5 Input type check user enterted information

I've had a quick look and couldn't find what I needed. I expect it to be something simple. I have an input text box whose type is set to a number with range between 1 to 20. This works perfectly.
However, the user can just type in abc or 21, which defeats the point. How can I set it so that the text box doesn't allow that?
maybe you can use "pattern"
<input type="text" pattern="[0-9]+" />
input type="number" and "range" not supported in Firefox.
You might want to solve using javascript, or, if it is only a matter of 20 numbers (ie 1-20), why not use a drop down?
such as:
<select>
<option>1</option>
</option>
etc...
HTML5 has a 'number' type input element. It looks like this:
<input type="number" name="quantity" min="1" max="5">
You can see it in action here: http://www.w3schools.com/html/tryit.asp?filename=tryhtml5_input_type_number
However, not every browser supports this, so you you may need to validate the input given by the user. This page will tell you which browsers support this feature:
