I have simple input box of type number with step='0.01'. I'd like to increase the current input value by the pre-defined step value using the up and down buttons situated on the very right side.
Now everything seems to work just fine while the number is less than or equals 13 digits. If it's greater it won't neither decrease nor increase the number by the step value. It just freezes the value not letting the user change the value using the up/down buttons.
<input id="test" type="number" min="0.00" value="" placeholder="" step="0.01" />

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 am only having this issue on firefox, it works as expected on chrome.
If I have a number input with a value of "20.00" or 20.00 (as a string or number) it always shows 20 without the decimal spaces inside the input box.
I need the type="number" so avoid other inputs that aren't numbers because of internal calculations that are done after the input.
For example:
<label>Input with number value as string</label>
<input type="number" value="20.00" step="0.01">
<br>
Input with number value as number
<input type="number" value=20.00 step="0.01">
How can I have the value inside the input show with the 2 decimal values in firefox?
I have two different number-type input fields, both with a declared min, max, and step. On one, the step works just fine with the arrows/spinner, and throws an error when someone manually enters a number that isn't divisible by the step value. The second number input field, set up exactly the same way, the step works fine with the arrows/spinner, but will allow someone to manually enter whatever value they want, and even submit the form with the "incorrect" number. (Example: step="2", and they entered and were able to submit a 5.)
the two boxes are on different pages, and the one that's giving me fits looks like this
<input style="width:75px;" type="number" id="updates_23705616199" max="120" name="updates[]" class="txtbox" value="2" min="2" data-id="23705616199" step="2">
I even extracted just this line to an html file by itself, and it still doesn't work then. The data-id field is a required bit for the page that it's in.
Please advise
Did you make sure your IDs are unique? I created a JSFiddle showing your example working. I also gave them unique names.
https://jsfiddle.net/pa9rodfL/
<input type="number" id="idName" class="className" name="nameName" min="11" max="15" step="2" >
<input type="number" id="idName2" class="className" name="nameName2" min="5" max="10" step="3" >
I have created an input box using <input type="text" name="username"> for user to input username, then i have fixed the length to 5 for some calculation.
<input type="text" name="username" maxlength="5">. but when i given the input as static text then it will accept any number of characters.
Setting max length to 5 means that the input box will hold only 5, then why it holds more than 5 letters when given like this?
<input type="text" name="username" maxlength="5" value="12345678910">
According to w3schools,
Maxlength eflects the maxlength HTML attribute, containing the maximum length
of text (in Unicode code points) that the value can be changed to. The
constraint is evaluated only when the value is changed
The key here is that it is only evaluated when the value is changed. You can set the value to anything when you're creating the element. The effect will take place after you change it. Try changing the input from your example, and you'll see that it does cap it at 5 characters.
I have some HTML that allows users to input a number like so:
<input type="number" min="1" name="aNumber" value="1" />
I noticed that at a certain point, the form data will change how it expresses the input -- i.e. it will change from "1000000" to "9.1e 32" when submitting the data to the server. But then I noticed at a certain point, it will simply be null.
What is the maximum value the input will still be able to send to the server?
After doing a bit of research in this jsfiddle: http://jsfiddle.net/43gW7/. It turns out that the its a 32 bit float with a range of float +/-3.4028234663e+38. When it exceeds that range, the value of the input returns null.
