I'm using ionic for an iOS app, my issue is that I can't keep trailing zeros in currency values when using an input with type number.
I need input number so the appropriate keyboard opens in iOS. ParseFloat toFixed wont work as it produces a string / exception. If I put the value 25.20 in the input it changes to 25.2, is there any solution to this?
$scope.total = 25.20;
<input type="number" name="total" value="{{total}}" placeholder="total amount" ng-model="total" min="1" max="2500" ng-pattern="/^[0-9]+(\.[0-9]{1,2})?$/" step="0.01">

I would like to know how can I use . to separate decimals in a HTML Input tag type="number" instead of , using Google Chrome (Version 89.0.4389.82) MacOs Catalina.
So far from what I've tried Firefox is the only browser which splits decimal numbers with .
Does anyone faced this issue?
Any ideas how to fix it?
<input type="number" value="1.5" step="0.1" min="0" />
Browser decimal separators differ according to the region. I think your issue is parsing the value for different regions( , and .)
Use valueAsNumber to extract the value
valueAsNumber (MDN Documentation)
double: Returns the value of the element, interpreted as one of the following, in order:
A time value
A number
NaN if conversion is impossible
window.addEventListener('DOMContentLoaded', (event) => {
const ageInput = document.querySelector('#age');
console.log('Age:', ageInput.valueAsNumber);
console.log('Type of Age:', typeof ageInput.valueAsNumber);
});
<input id="age" type="number" value="1.5" step="0.1" min="0" pattern="[0-9]+([,\.][0-9]+)?" />
Also added pattern for sake of completeness.
I create a form, where one field should only be filled with numbers.
I want that field can be filled only with numbers since entering input.
Like this example :
How Can I Use Javascript to Allow Only Numbers to Be Entered in a TextBox?
I've tried using Regex, but when I try to input is still able to enter letters.
<input type="number" min="2" pattern="^[0-9]" class="andi_input required-entry" name="amount" id="amount" required title='Only Number' />
I want it when input to field and not after click the Submit button and the message appear and inform that the field can only be filled with numbers.
I also try to add validate-number, but the result is the same.
How, without javascript, so that the field can only be filled with numbers or letters?
Whether for this kind of case have to use JavaScript or is there another way without JavaScript?
HTML 5 uses the type="number" so make sure that the browser that you are using is compatible. Check it out in action here.
You should check browser compatibility.
You're right with <input type="number" pattern="^[0-9]" />.
Your regex rule is :
^[0-9] :
^ assert position at start of the string
[0-9] match a single character present in the list below
(0-9 a single character in the range between 0 and 9)
You can check your regex here.
I use to use HTML5 Validation and jQuery one because IE is capricious most of the time.
UPDATE :
Without Javascript it's not possible to check pattern on real time. I suggest you to use a jQuery library like : http://www.jqueryscript.net/form/jQuery-Plugin-For-Formatting-User-Input-with-Specified-Pattern-formatter-js.html.
Here is a OneLiner:
<input type="number" onkeypress="return /[0-9]/i.test(event.key)">
or
<input type="text" onkeypress="return /[a-z]/i.test(event.key)">
I just have a simple question after having searched for hours now: Is there any possibility to show the decimal keyboard in webbrowsers input fields? input type="number" only shows numbers but i need a comma or dot instead in the bottom left corner.
I tried anything, pattern, step etc., but nothing brings up the decimal keyboard. I only need the numbers and a dot or comma, no A-Z or a-z or anything else.
<input type="number" id="inputNumbers" pattern="[0-9]*" size="30" min="1" max="5">
This is what i get:
This is what i want:
Checkout inputmode="decimal" starting on iOS 12.2
https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/inputmode
https://caniuse.com/#feat=input-inputmode
https://github.com/mrchandoo/cordova-plugin-decimal-keyboard
Lets you configure the decimal character(instead of . you can change to , )
This works for iPhone and Android:
<input type="text" inputmode="decimal">
Results in this keypad with iPhone 10:
And with Android:
Try this:
EditText myEditText = (EditText)findViewById(R.id.myEditText);
myEditText.setInputType(InputType.TYPE_NUMBER_FLAG_DECIMAL);
Or:
<input type="tel" />
This is a bit of a hack:
<input type="number" step="0.01">
Might work depending on what you are trying to achieve when it comes to input values

Hope you come right!
Check this html code according to your pattern
<input type="text" pattern="[a-z]*">
my code is as follows:
<input type="number" min="4.50" max="9.90" id="cpi" name="cpi" required="required" title="CPI" class="formfield3" />
CPI is a float value. But if I open it in browser and input value which is the float number such as 7.89 then it shows message of 'Invalid Value'. How to solve it?
Set step="any"
<input type="number" min="4.50" max="9.90" step="any" id="cpi" name="cpi" required="required" title="CPI" class="formfield3" />
The number type has a step value controlling which numbers are valid (along with max and min), which defaults to 1. This value is also used by implementations for the stepper buttons (i.e. pressing up increases by step).
Simply change this value to whatever is appropriate. For money, two decimal places are probably expected:
<input type=number step=0.01 />
(I'd also set min=0 if it can only be positive)
As usual, I'll add a quick note: remember that client-side validation is just a convenience to the user. You must also validate on the server-side!
Is it possible to combine a pattern attribute with a maxlength attribute on an input field in jquerymobile?
<input name="aNumber" type="number" pattern="[0-9]{6}" maxlength="6" placeholder="dddddd" value="">
<input name="anotherNumber" type="number" pattern="[0-9]{3,4}" maxlength="4" placeholder="ddd(d)" value="">
I want the big numberpad to appear but that only works using pattern="[0-9]*". Unfortunately the maxlength attribute is not respected in any case.
What I want is a numeric keypad to appear (the big one/dial; the iPhone apparently has two: only numbers/dial and numbers with special chars) letting the user input up to 6 or 3 to 4 numeric chars.
Edit: Applied #raina77ow 's suggestion and that works for the moment, but still it feels not right so I'm open to advice!
<input name="aNumber" type="tel" pattern="[0-9]*" maxlength="6" placeholder="dddddd" value="">
{6} means exactly 6 Digits
{0,6} means minimum 0 digits and maximum 6 digits
type="tel" pattern="{X,6}" maxlength="6"
if you wanna limit input to strictly numbers (as in math numbers not telephone numbers) go with:
pattern="[0-9]{X,6}"
Where x is an integer number between 0 and 6 will get you the minimum of X and maximum of 6 digits for input.
If you type pattern this way, you need maxlength only for browsers that don't support pattern attribute, I would keep it.
