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" />.

<input type="number" placeholder="Can be a value like 4.23" step="0.01">
This accepts decimal numbers, but makes the + / - controls increment by 0.01... not very user friendly. I thought perhaps something like this might work...
<input type="number" placeholder="Doesn't allow a value like 4.23" step="1.00">
However my browser (Chrome 85) just rounds this back to 1 and rejects 4.23 as invalid.
Some have suggested that using any is the solution... I disagree as I want the field to only allow a maximum of 2 decimal places.
<input type="number" placeholder="Allows 4.2333333333333" step="any">
It seems to me that the increase/decrease step function should not be coupled with the validity of the number, it should just change the way that the + and - buttons work.
I searched around and found others asking the same question, but I haven't found a resolution.
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 need to add "0" as an allowable value which is outside the max/min range:
<input type="number" min="70" max="94" value="0" required>
I'm trying to avoid using JavaScript if possible.
It appears that the solution for input of this type is to use the pattern attribute instead of min/max.

I don't have the exact regex off the top off my head for your case, but it should be pretty easy. (and I presume yours is only an example anyhow.)
I have a similar issue, where I have number inputs for 0-100 but also need to allow a few values with special meaning like 996-999.
I have noticed that Firefox (unlike any other browser) is treating the min=".1" tag as the required decimal rather than the minimum number that can be accepted in a input type="number" box like this one:
<input id="numberInput" type="number" min=".1" value="1">
If I set it to 1 or any other whole number, a red box will appear around the input (implying the input is invalid). But if the input is changed to 1.1 or any other number ending in .1 (such as 2.1 or 10.1) it removes the red box, implying that this value checks out.
Here is a fiddle
Anyone know what is going on here?
Before you tell me, I do know that I can add step="any" to fix this "problem", but that seems like it should be unnecessary to do given that MIN is just supposed to set the floor on the input based on the HTML5 standard as described here
I have a field for phone number but i dont want users to put like +1 but instead to write the local number .
How can i make the number to start with 6?
this is the input : how can i disable the +1 nor
If I've understod this correctly then you just might wanna add a placeholder as an element to the input, stating the user to type the local number. Another solution might be to add a value to the input. Both very simple things to add if it's the desired outcome.
<input type="text" placeholder="Write local number"/>
<input type="text" value="6"/>
Example to the two solutions:
JSfiddle
I used a minimum and maximum to make sure the phone number is correct. thanks.
so practically is kinnda the same as what i was wanting
This is what i used:
