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!

I'm implementing a text box in HTML with the MaxLength attribute. I want it to be 4 digits only but ignoring decimals. So a user should only be able to write a number from 0 to 9999. however, I want them to be able to add decimals like 9011.22. What would be the best way to go about implementing this? Will it need some kind of javascript?
here is my HTML tag:
<input type="text" name="lastname" value="Mouse">
Use the number type, it will allow you to set a min and a max. You can then use the step attribute to control the number of decimals.
You can add the required property to make this field required.
You can use this.checkValidity() in the onblur event to validate before submitting.
<form>
<input type="number" name="lastname" value="Mouse" min="0" max="9999" step="0.01">
<p><input type="submit" value="Submit"></p>
</form>
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 have one textbox which is of number type. I want it to accept maximum of 16 digits, not more than that. For that I have tried with "maxlength" attribue and "max" attribute both. But its not working. Can anyone provide me solution?
<input type="number" id="dummy" max="16" />
Edit: I need to enter only whole number since it is used for account number of bank.
There are a few of these "how do I further control type="number" fields" questions here on SO. It boils down to:
You make it a type="number" and accept that you can't further mask the input vs. what the browser does to implement a numeric input, or
You make it type="text" and use pattern and/or maxlength to enforce the specific pattern you want, and accept that the browser won't add a specific UI for numbers.
Input type number doesn't support "maxlength" attribute. You can specify "max" attribute (HTML5), which is the highest number user can input. Something like this: <input type="number" max="999999999999" id="dummy" step="1" min="0">.
Edit: Also specify step attribute to 1.
I made a HTML input which accepts decimal only.
<input type="text" class="form-control" id="price" name="price" placeholder="Price"
onkeyup="this.value=this.value.replace(/[^0-9\.]/g,'')">
This is working. However I need to modify the regex to accept only one period
Correct: 9.999
Wrong: 9.9.99.99
Is there a way? please don't use jquery validate and html type="number" (Users doesn't want the up and down arrow when you set the input to type number) Thanks
Sharing this answer to limit one period on decimal input
replace
this.value=this.value.replace(/[^0-9\.]/g,'')
with
this.value=this.value.replace(/[^0-9.]/g, '').replace(/(\..*)\./g, '$1')
I want to allow the user to only enter postive numbers and numbers less then 100.
How can i modify this input markup to get my required validation.
<input data-bind="value : $root.rootData.Page" class="form-control">
Edit: I know i can validate in JS, but for my particular case i want to do it solely in the makrup.
You can use regular expressions with HTML5 using the pattern attribute.
How can I validate number between 1 and 99 using regular expression? - Will give you some information about different ways to check if a number is between 1 and 99
From your example, you could use the following
<input data-bind="value : $root.rootData.Page" class="form-control" pattern="^[1-9][0-9]?$">
instead of using regex to match a number field, why not just use the number type and provide min/max?
<input type="number" min="1" max="99" step="1" data-bind="value : $root.rootData.Page" class="form-control" />
Regex could be used in combination with number type as a fallback, since FF support for the number type is lacking:
<input type="number" min="1" max="99" step="1" pattern="^[1-9][0-9]?$" data-bind="value : $root.rootData.Page" class="form-control" />
