How to avoid Decimal values from input of Number in HTML5. Currently it allows user to type decimal value.

To prevent e and dot in an input type number with React, we can validate the input value in the onChange prop function. const C = () => { //... const [val, setVal] = useState(""); return ( <div className="App"> <input type="text" value={val} onChange={(e) => setVal(e. target.
The C++ setprecision can also be used to format only the decimal places instead of the whole floating-point or double value. This can be done using the fixed keyword before the setprecision() method.
An alternative to the supplied answers is to monitor the keypress while in the input. I personally like leaving the type="number" as an attribute. Here's a JSFiddle
<form action="#" method="post"> Numbers: <input name="num" type="number" min="1" step="1" onkeypress="return event.charCode >= 48 && event.charCode <= 57" title="Numbers only"> <input type="submit"> </form> If you love us?
