You can alter the number of decimal places by varying the value passed into the toFixed method. See MDN docs. Learn more. Asked 4 years, 4 months ago. Active 2 months ago. Viewed k times. Basically, I am asking for a price input.
It should be noted that, while the user may type any number of digits after the decimal place, most browsers will not allow the submission of the form with an invalid value and the CSS selectors :valid and :invalid are applied as expected.
Nathan, it is also trivial to test browser validation. Try submitting a value with more than 2 decimal places: jsfiddle.

Derek I can only assume the setTimeout is to wait for the keydown event to complete before setting the newVal otherwise it'll be the same as the oldVal. However, with a timeout of 0, it's pointless and doesn't work as both values are often the same in Firefox.

An alternative to the supplied answers is to monitor the keypress while in the input. Here's a JSFiddle. I ended up checking to see if a user types in a period then preventing the event from propagating. Edit : A better approach. The key press event has been deprecated. Also added in a regex to strip out everything but numbers  on paste. Caution Experimental. Only partially works on chrome: Wanted to look at a great way to grab the pasted value strip everything out then have it placed in input as normal.
With the above method you are relying on the event order to correct the input, then any event listeners will ideally fire after. The onpaste method will fire before the input event fires so you keep the flow of events correct. However when replacing the string with only numbers the decimal point would still sneak in.

I tried the pattern method, But i would like to have behaviour same as number field. Just like a number field doesn't allow user to type alphabets, is there any way i could stop period value too.
Active Oldest Votes. This solution works great to avoid inputs other than numbers . It looks like this also disables backspace and delete keys in FireFox which isnt ideal when editing the input field. This not works if we open site in mobile browser.

Just a note: This seems to only validate on submit of the form that the input is in; it doesn't prevent decimal input, nor does it indicate that the field is in error before the form is submitted.

I'm making a form where the user can enter a dollar amount using an html number input tag. Is there a way to have the input box always display 2 decimal places? By changing the '2' in toFixed you can get more or less decimal places if you so prefer.
What other folks posted here mainly worked, but using onchange doesn't work when I change the number using arrows in the same direction more than once. What did work was oninput.
HTML5 Input: Numbers with Decimals
My code mainly borrowing from MC :. An even simpler solution would be this IF you are targeting ALL number inputs in a particular form :.
Groot Groot Unfortunately doesn't seem to be working in Firefox This is not working, becouse if you have a placeholder it will take by default that value and you can't change it in input. Actually, even with the placeholder, this works on Google Chrome and Microsoft Edge, tested. Nice solution, anyway, that doesn't work with Firefox version Ivaylo Strandjev Ivaylo Strandjev I'm saving it with a backbone model that uses a float for this data, so thats not the problem.
I just want to have the number displayed in the text box have two decimal places. Nevermind, I misunderstood what you were saying I like to use jQuery's. This is just a minimalist solution, but yes using jQuery could make the OPs life easier.
There is a similar question which limits the number of characters for allowed in a form input. In my case I want to limit the number of digits that can be added after the decimal point to 2 digits.
Note that I used the keyup event here, so that you can see the automatic deletion. But it works great with input too! We could generalize this method to work with multiple inputs, using a custom attribute like decimals : I'm using input event here, so you see the difference. I think best option is to resovle this with jQuery validator, where you can add requirments for each field that you are using. If you are trying to resovle this with HTML5 it might happen that in some browsers it will not work in a way you want.
The following solution works with number inputs and therefor defends against alphabetical characters unlike the currently accepted answer :.

With my method you can type text 2. As your question didn't explicitly mention that the decimals must be at the end of the inputI prefer to stick with my method.They include built-in validation to reject non-numerical entries. The browser may opt to provide stepper arrows to let the user increase and decrease the value using their mouse or by simply tapping with a fingertip.
On browsers that don't support inputs of type numbera number input falls back to type text. Any floating-point number, or empty. You can set a default value for the input by including a number inside the value attribute, like so:.
In addition to the attributes commonly supported by all element is used to create interactive controls for web-based forms in order to accept data from the user; a wide variety of types of input data and control widgets are available, depending on the device and user agent. Any values in the list that are not compatible with the type are not included in the suggested options.
The values provided are suggestions, not requirements: users can select from this predefined list or provide a different value. The maximum value to accept for this input. If the value entered into the element exceeds this, the element fails constraint validation. If the value of the max attribute isn't a number, then the element has no maximum value. The minimum value to accept for this input. If the value of the element is less than this, the element fails constraint validation.
If a value is specified for min that isn't a valid number, the input has no minimum value. The placeholder attribute is a string that provides a brief hint to the user as to what kind of information is expected in the field.
It should be a word or short phrase that demonstrates the expected type of data, rather than an explanatory message. The text must not include carriage returns or line feeds. If the control's content has one directionality LTR or RTL but needs to present the placeholder in the opposite directionality, you can use Unicode bidirectional algorithm formatting characters to override directionality within the placeholder; see Overriding BiDi using Unicode control characters in The Unicode Bidirectional Text Algorithm for those characters.
Note: Avoid using the placeholder attribute if you can. It is not as semantically useful as other ways to explain your form, and can cause unexpected technical issues with your content. See element is used to create interactive controls for web-based forms in order to accept data from the user; a wide variety of types of input data and control widgets are available, depending on the device and user agent.
A Boolean attribute which, if present, means this field cannot be edited by the user. Note: Because a read-only field cannot have a value, required does not have any effect on inputs with the readonly attribute also specified. The step attribute is a number that specifies the granularity that the value must adhere to, or the special value anywhich is described below.
Only values which are equal to the basis for stepping min if specified, value otherwise, and an appropriate default value if neither of those is provided are valid. A string value of any means that no stepping is implied, and any value is allowed barring other constraints, such as min and max.
Note: When the data entered by the user doesn't adhere to the stepping configuration, the user agent may round to the nearest valid value, preferring numbers in the positive direction when there are two equally close options. The default stepping value for number inputs is 1allowing only integers to be entered— unless the stepping base is not an integer.
When you create a number input with the proper type value, numberyou get automatic validation that the entered text is a number, and usually a set of up and down buttons to step the value up and down. Important : Bear in mind that, logically, you should not be able to enter characters inside a number input other than numbers.If you change the input values and then click the "Reset" button, the form-data will be reset to the default values.
You can also use the min and max attributes to add restrictions to dates:. Some smartphones recognize the email type, and add ". The following example displays a numeric input field, where you can enter a value from 0 toin steps of The default value is Default range is 0 to However, you can set restrictions on what numbers are accepted with the minmaxand step attributes:.

When user uses dot sign from numeric keyboard, there is emitted 'Decimal' key event and directive not work properly. You should remember, that is still possible to paste some wrong data into input.
That's why, you probably need one more validation, maybe on Input event to prevent pasting wrong data. Easiest way to achieve that would be binding to the "keypress" event and validate with a regex expression whether that's a valid input or not. Maybe you should also look the Form Validation in the Angular guide. It can be useful depending of your form type. I am using ng2-currency-maskit is pretty useful. Below coding is to make textbox to allow numeric field with two decimal places above two decimal places will give warning ,without using regex:.

Active Oldest Votes. String next. Your answer is working fine but when we try to edit value before decimal, then it is not allowing me to input any number. GobindGupta thanx for sharing issue. Now it's fixed! Yes it is fixed. You can also rename position as startPosition to keep everything consistent.
