One event listener to rule them all

This is similar to @Simon Perepelitsa's answer in pure js, but a bit simpler, as it puts one event listener on the document element for all inputs and checks if the focused element is a number input type:

document.addEventListener("wheel", function(event){
    if(document.activeElement.type === "number"){
        document.activeElement.blur();
    }
});

If you want to turn off the value scrolling behaviour on some fields by class/id, but not others just add && and the corresponding document selector instead:

document.addEventListener("wheel", function(event){
    if(document.activeElement.type === "number" &&
       document.activeElement.classList.contains("noscroll"))
    {
        document.activeElement.blur();
    }
});

with this:

<input type="number" class="noscroll"/>

If an input has the noscroll class it wont change on scroll, otherwise everything stays the same.

Test here with JSFiddle

$(document).on("wheel", "input[type=number]", function (e) {
    $(this).blur();
});

You can simply use the HTML onwheel attribute.

This option have no effects on scrolling over other elements of the page.

And add a listener for all inputs don't work in inputs dynamically created posteriorly.

Aditionaly, you can remove the input arrows with CSS.

input[type="number"]::-webkit-outer-spin-button, 
input[type="number"]::-webkit-inner-spin-button {
    -webkit-appearance: none;
    margin: 0;
}
input[type="number"] {
    -moz-appearance: textfield;
}

<input type="number" onwheel="this.blur()" />

I have an alternative suggestion. The problem I see with most of the common recommendation of firing a blur event is that it has unexpected side-effects. It's not always a good thing to remove a focus state unexpectedly.

Why not this instead?

<input type="number" onwheel="return false;" />

It's very simple and straight-forward, easy to implement, and no side-effects that I can think of.

ReactJS Solution

For those needing a React solution, here's an onWheel handler for your type="number" input to prevent the number from changing and prevent the page from scrolling while the user tries to wheel over the input. Finally, it'll refocus on the input so the user can keep editing as intended:

const numberInputOnWheelPreventChange = (e) => {
  // Prevent the input value change
  e.target.blur()

  // Prevent the page/container scrolling
  e.stopPropagation()

  // Refocus immediately, on the next tick (after the current function is done)
  setTimeout(() => {
    e.target.focus()
  }, 0)
}

return <input type="number" onWheel={numberInputOnWheelPreventChange}/>

For anyone working with React and looking for solution. I’ve found out that easiest way is to use onWheelCapture prop in Input component like this:

onWheelCapture={e => {
  e.target.blur()
}}

input = document.getElementById("the_number_input")
input.addEventListener("mousewheel", function(event){ this.blur() })

For jQuery example and a cross-browser solution see related question:

HTML5 event listener for number input scroll - Chrome only

@Semyon Perepelitsa

There is a better solution for this. Blur removes the focus from the input and that is a side affect that you do not want. You should use evt.preventDefault instead. This prevents the default behavior of the input when the user scrolls. Here is the code:

input = document.getElementById("the_number_input")
input.addEventListener("mousewheel", function(evt){ evt.preventDefault(); })

First you must stop the mousewheel event by either:

1. Disabling it with mousewheel.disableScroll
2. Intercepting it with e.preventDefault();
3. By removing focus from the element el.blur();

The first two approaches both stop the window from scrolling and the last removes focus from the element; both of which are undesirable outcomes.

One workaround is to use el.blur() and refocus the element after a delay:

$('input[type=number]').on('mousewheel', function(){
  var el = $(this);
  el.blur();
  setTimeout(function(){
    el.focus();
  }, 10);
});

Easiest solution is to add onWheel={ event => event.currentTarget.blur() }} on input itself.

Typescript Variation

Typescript needs to know that you're working with an HTMLElement for type safety, else you'll see lots of Property 'type' does not exist on type 'Element' type of errors.

document.addEventListener("wheel", function(event){
  const numberInput = (<HTMLInputElement>document.activeElement);
  if (numberInput.type === "number") {
    numberInput.blur();
  }
});

In my case, I needed to maintain focus and still apply the scroll. None of the solutions above can handle that and doing blur/focus feels a bit hacky to me.

This maintains existing focus and also keeps the scroll. You know... like the browser should. Only minimally tested in chrome and only supports Y-axis.

// you could make this target a specific input instead of document
document.addEventListener('wheel', event => {
  if (!event.target) return;
  const isNumberInput = event.target.nodeName === 'INPUT' && event.target.type === 'number';
  const isFocused = event.target === document.activeElement;
  if (isNumberInput && isFocused) {
    // prevent stupid input change
    event.preventDefault();
    // since we're taking over scrolling, we want to make sure
    // nothing else gets the event
    event.stopPropagation();
    // finally we reapply the scroll
    applyScroll(event);
  }
}, { passive: false });

// this walks up the tree for event.target to find the first
// scrollable parent.  this is probably good enough for most situations.
const applyScroll = event => {
  try {
    // console.debug('attempting to reapply scroll. searching for scrollable container...');
    let scrollContainer = event.target;
    while (scrollContainer && scrollContainer !== document.body && !elementIsScrollable(scrollContainer)) {
      scrollContainer = scrollContainer.parentElement;
      // console.debug('\t-> container was not scrollable. checking parent', scrollContainer);
    }
    if (scrollContainer) {
      // console.debug('scrollContainer container found. applying scroll', scrollContainer, event.deltaY);
      scrollContainer.scrollBy({ top: event.deltaY });
    }
    else {
      // console.debug('no scrollContainer found');
    }
  }
  catch (err) {
    console.info('failed to reapply scroll', err, event);
  }
};

const elementIsScrollable = element => {
  const { scrollHeight = 0, offsetHeight = 0 } = element;
  const scrollable = style.overflowY === 'auto' || style.overflowY === 'scroll';
  return scrollable && scrollHeight > 0 && offsetHeight > 0 && element.scrollHeight > element.offsetHeight;
};

The provided answers do not work in Firefox (Quantum). The event listener needs to be changed from mousewheel to wheel:

$(':input[type=number]').on('wheel',function(e){ $(this).blur(); });

This code works on Firefox Quantum and Chrome.

For those using react, here's a stand-alone hook the worked well for my use case -- prevent the number changing, retain scroll of parent, and retain focus without jumping back to the input.

Just import and use the hook at the index of your app to effect all inputs of type number.

import { useEffect } from 'react';

/**
 * By default, when a user scrolls while focusing and hovering a number input, the input's value will change.
 *
 * This hook disables that behavior while maintaining focus in the input and allowing the user to scroll the page.
 */
function useDisableScrollOnNumberInput() {
  useEffect(() => {
    const disableScroll = () => {
      const el = document?.activeElement;

      if (!(el instanceof HTMLInputElement) || el?.type !== 'number') return;

      el.blur();
      setTimeout(() => el.focus({ preventScroll: true }), 0);
    };

    document.addEventListener('wheel', disableScroll);
    return () => document.removeEventListener('wheel', disableScroll);
  }, []);
}

export default useDisableScrollOnNumberInput;

While trying to solve this for myself, I noticed that it's actually possible to retain the scrolling of the page and focus of the input while disabling number changes by attempting to re-fire the caught event on the parent element of the <input type="number"/> on which it was caught, simply like this:

e.target.parentElement.dispatchEvent(e);

However, this causes an error in browser console, and is probably not guaranteed to work everywhere (I only tested on Firefox), since it is intentionally invalid code.

Another solution which works nicely at least on Firefox and Chromium is to temporarily make the <input> element readOnly, like this:

function handleScroll(e) {
  if (e.target.tagName.toLowerCase() === 'input'
    && (e.target.type === 'number')
    && (e.target === document.activeElement)
    && !e.target.readOnly
  ) {
      e.target.readOnly = true;
      setTimeout(function(el){ el.readOnly = false; }, 0, e.target);
  }
}
document.addEventListener('wheel', function(e){ handleScroll(e); });

One side effect that I've noticed is that it may cause the field to flicker for a split-second if you have different styling for readOnly fields, but for my case at least, this doesn't seem to be an issue.

Similarly, (as explained in James' answer) instead of modifying the readOnly property, you can blur() the field and then focus() it back, but again, depending on styles in use, some flickering might occur.

Alternatively, as mentioned in other comments here, you can just call preventDefault() on the event instead. Assuming that you only handle wheel events on number inputs which are in focus and under the mouse cursor (that's what the three conditions above signify), negative impact on user experience would be close to none.

If you want a solution that doesn’t need JavaScript, combining some HTML functionality with a CSS pseudo-element does the trick:

span {
  position: relative;
  display: inline-block; /* Fit around contents */
}

span::after {
  content: "";
  position: absolute;
  top: 0; right: 0; bottom: 0; left: 0; /* Stretch over containing block */
  cursor: text; /* restore I-beam cursor */
}

/* Restore context menu while editing */
input:focus {
  position: relative;
  z-index: 1;
}

<label>How many javascripts can u fit in u mouth?
  <span><input type="number" min="0" max="99" value="1"></span>
</label>

This works because clicking on the contents of a <label> that’s associated with a form field will focus the field. However, the “windowpane” of the pseudo-element over the field will block mousewheel events from reaching it.

The drawback is that the up/down spinner buttons no longer work, but you said you had removed those anyway.

In theory, one could restore the context menu without requiring the input to be focused first: :hover styles shouldn’t fire when the user scrolls, since browsers avoid recalculating them during scrolling for performance reasons, but I haven’t thoroughly cross-browser/device tested it.

I was struggling with the solution. So, This and other posts help me to do this. We need to change some stuff regarding the best answer here. So in order to disable scrolling, we must add the following:

<script>
$(document).ready(function() {
    $('input[type=number]').on('wheel',function(e){ $(this).blur(); }); 
});
</script>

Instead of using "onwheel" we use "wheel" :)

Non-JS solution

I like using type=number since it brings up a nice keyboard on iOS.

The keyboard is nice indeed. But we can get the same behaviour with:

<input inputmode="numeric" pattern="[0-9]*" />

Taken from gov.uk which was linked in the MUI docs. Works nicely for our product.

Grain of salt

Please check browser support for inputmode. Most mobile browsers are supported, and to me inputmode is mostly about the mobile experience. But YMMV.

I found the ultimate solution for this. I know this thread has like 100 replies but zero of them worked for me. I'm using a low code platform that operates on a cyclone of react code mixed with JSON Schema Forms that are generated on the fly. This tiny but of CSS fixed the problem (Tested in Edge (Chrome based) and Firefox):

input[type="number"]:focus,
input[type="number"]:hover {
    pointer-events: none;
    cursor: text;
}

The only side effect is that the cursor changes to an arrow but it still functions normally. Adding the "cursor: text" line attempts to force the cursor back to the right one but it ends up almost the ghost of two cursors together.

Angular solution. One directive to rule them all!

In contrast to other solutions, with this solution the user

• does not loose focus on the input
• and still able to scroll!

See it on StackBlitz

import { Directive, ElementRef, NgZone, OnDestroy } from '@angular/core';
import { fromEvent, Subscription, takeUntil } from 'rxjs';
import { tap, switchMap } from 'rxjs/operators';

@Directive({
  selector: 'input[type=number]',
})
export class FixNumberInputScrollDirective implements OnDestroy {
  private subs = new Subscription();

  constructor(elRef: ElementRef<HTMLInputElement>, zone: NgZone) {
    const el = elRef.nativeElement;
    const focus$ = fromEvent(el, 'focus');
    const blur$ = fromEvent(el, 'blur');

    // when input is focused, start listening to the scroll of element. On this event blur and
    // re-focus on the next tick. This allows for the page scroll to still happen, but the unwanted
    // input number change is prevented.
    // Stop listening to the scroll when focus is lost
    const preventWheel$ = focus$.pipe(
      switchMap(() => {
        return fromEvent(el, 'wheel', { passive: false }).pipe(
          tap(() => {
            zone.runOutsideAngular(() => {
              el.blur();
              setTimeout(() => {
                el.focus();
              }, 0);
            })
          }),
          takeUntil(blur$)
        );
      })
    );

    this.subs.add(preventWheel$.subscribe());
  }

  ngOnDestroy() {
    this.subs.unsubscribe();
  }
}

import { WheelEvent } from 'react';

const numberInputOnWheelPreventChange = (e: WheelEvent<HTMLInputElement> | undefined) => {
    e?.currentTarget?.blur();
  };

This worked for me!!

function fixNumericScrolling() {
$$( "input[type=number]" ).addEvent( "mousewheel", function(e) {
    stopAll(e);     
} );
}

function stopAll(e) {
if( typeof( e.preventDefault               ) != "undefined" ) e.preventDefault();
if( typeof( e.stopImmediatePropagation     ) != "undefined" ) e.stopImmediatePropagation();
if( typeof( event ) != "undefined" ) {
    if( typeof( event.preventDefault           ) != "undefined" ) event.preventDefault();
    if( typeof( event.stopImmediatePropagation ) != "undefined" ) event.stopImmediatePropagation();
}

return false;
}

Most answers blur the number element even if the cursor isn't hovering over it; the below does not

document.addEventListener("wheel", function(event) {
  if (document.activeElement.type === "number" &&
    document.elementFromPoint(event.x, event.y) == document.activeElement) {
    document.activeElement.blur();
  }
});

Antd / React + Typescript answer

    const myComponent = () => {
      const inputRef: React.RefObject<HTMLInputElement> = createRef();
      
      return <Input

           }
           e.preventDefault();
          }}
      />
    }

const disableNumberInputChangeOnMouseScroll = (): void => {
    let currentFocus: EventTarget | null = null;

    document.addEventListener("focusin", (event) => {
        currentFocus = event.target;
    });

    document.addEventListener("wheel", (_event) => {
        const activeElement = document.activeElement;
        if (activeElement?.tagName === "INPUT" && (activeElement as HTMLInputElement).type === "number") {
            const numberInput = activeElement as HTMLInputElement;
            // blur removes focus from the input, preventing the scroll from changing the value.
            numberInput.blur();
            if (currentFocus === numberInput) {
                // but at the same time, if the caret (https://en.wikipedia.org/wiki/Caret_navigation) was in the input,
                // we want to make sure the focus is restored.
                window.setTimeout(() => numberInput.focus({ preventScroll: true }), 1);
            }
        }
    });
};

Number input does not change on scroll, but at the same time, an user does not lose focus if the caret is in the input.

The best solution for me:

 <input type="number" onwheel="wheelOnNumber(event)" />

 <script>
 const wheelOnNumber = (event) => {
      const target = event.target;
      target.blur();
      setTimeout(() => {
        target.focus();
      });
  };
 </script>
