  style="max-width: 200px;"
></quiet-number-input>

Examples Jump to heading

Labels and descriptions Jump to heading

You can use the label and description attributes to provide plain text labels and descriptions for the number input. If you want to provide HTML, use the label and description slots instead.

How to determine age 
<quiet-number-input name="name" label="Kitten age (months)" style="max-width: 200px;">
  <span slot="description">
    <a href="https://example.com/" target="_blank">How to determine age</a>
  </span>
</quiet-number-input>

Providing an initial value Jump to heading

Use the value attribute to provide an initial value for the number input.

<quiet-number-input 
  name="name" 
  label="Treats given today"
  value="2"
  style="max-width: 200px;"
>
</quiet-number-input>

Setting min, max, and step Jump to heading

Use the min and max attributes to set a minimum and maximum value for the number input. Use the step attribute to change the granularity the value must adhere to. 

<quiet-number-input 
  name="donation" 
  label="Monthly shelter donation"
  description="Amount in dollars (5-100)"
  min="5"
  max="100"
  step="5"
  value="25"
  style="max-width: 200px;"
></quiet-number-input>

Adding a placeholder Jump to heading

Use the placeholder attribute to show a placeholder in the number input when it's empty.

<quiet-number-input 
  type="number"
  label="Weight"
  description="Measured in pounds"
  min="0"
  step="0.5"
  placeholder="10.5"
  style="max-width: 200px;"
></quiet-number-input>

Start and end content Jump to heading

Use the start and end slots to add presentational icons or text. Avoid interactive elements such as buttons, links, etc. Works well with <quiet-icon> and <svg> elements.

$ 

<div style="max-width: 200px;">
  <quiet-number-input type="number" value="100" name="adoption" label="Adoption fee">
    <span slot="start">$</span>
  </quiet-number-input>  

  <br>

  <quiet-number-input type="number" value="30" name="playtime" label="Playtime minutes">
    <quiet-icon slot="end" name="clock"></quiet-icon>
  </quiet-number-input>

  <br>

  <quiet-number-input name="treats" value="2" label="Daily treats">
    <quiet-icon slot="start" name="cat"></quiet-icon>
    <quiet-icon slot="end" name="cookie"></quiet-icon>
  </quiet-number-input>
</quiet-number-input>

Changing the appearance Jump to heading

Set the appearance attribute to normal, filled, or unstyled to change the number input's appearance. 



<div style="max-width: 200px;">
  <quiet-number-input appearance="normal" label="Normal number input" placeholder="Enter number" style="max-width: 200px;"></quiet-number-input><br>
  <quiet-number-input appearance="filled" label="Filled number input" placeholder="Enter number" style="max-width: 200px;"></quiet-number-input><br>
  <quiet-number-input appearance="unstyled" label="Unstyled number input" placeholder="Enter number" style="max-width: 200px;"></quiet-number-input>
</div>

Pill-shaped number inputs Jump to heading

Number inputs can be rendered with pill-shaped edges by adding the pill attribute.

<quiet-number-input pill label="Whiskers count" style="max-width: 200px;"></quiet-number-input>

Without steppers Jump to heading

Add the without-steppers attribute to remove the stepper buttons.

<quiet-number-input 
  name="name" 
  label="Purrs per minute" 
  value="25"
  without-steppers
  style="max-width: 200px;"
></quiet-number-input>

<div style="max-width: 200px;">
  <quiet-number-input size="xs" label="Hairball count (xs)"></quiet-number-input><br>

Showing labels on the side Jump to heading

With the quiet-side-label utility, you can show labels on the side instead of on top of the number input. You can control the width of the label by setting the --label-width custom property. 


<div style="max-width: 300px;">
  <quiet-number-input
    class="quiet-side-label"
    style="--label-width: 12ch;"
    name="name" 
    label="Age" 
    description="How old is your feline friend?"
  ></quiet-number-input>
  <br>
  <quiet-number-input
    class="quiet-side-label"
    style="--label-width: 12ch;"
    type="number" 
    name="email" 
    label="Weight" 
    description="In pounds, please be honest!"
  ></quiet-number-input>
</div>

Validation Jump to heading

A number of attributes can be used to enable validation using the Constraint Validation API . These include required, pattern, minlength, maxlength, min, max, and step. They work exactly like their native counterparts.




Submit Reset 
<form action="about:blank" method="get" target="_blank" style="max-width: 200px;">
  <quiet-number-input name="required" label="Number of cats" required></quiet-number-input><br>
  <quiet-number-input name="min" label="Minimum cats (min 3)" required min="3"></quiet-number-input><br>
  <quiet-number-input name="max" label="Maximum cats (max 10)" required max="10"></quiet-number-input><br>
  <quiet-button type="submit" variant="primary">Submit</quiet-button>
  <quiet-button type="reset">Reset</quiet-button>
</form>

Using custom validation Jump to heading

Use the setCustomValidity() method to make the number input invalid and show a custom error message on submit. This will override all other validation parameters. To clear the error, remove the attribute or set it to an empty string.


Submit 
<form action="about:blank" method="get" target="_blank" id="number-input__custom-validation">
  <quiet-number-input 
    name="name"
    label="Happiness level (1-10)"
    description="This field will be invalid until custom validation is removed"
    style="max-width: 200px;"
  ></quiet-number-input>
  <br>
  <quiet-button type="submit" variant="primary">Submit</quiet-button>
</form>

<script type="module">
  import { allDefined } from '/dist/quiet.js';

  await allDefined();

  const form = document.getElementById('number-input__custom-validation');
  const textField = form.querySelector('quiet-number-input');

  textField.setCustomValidity('Not so fast, bubba!');
</script>

Styling validation Jump to heading

You can style valid and invalid number inputs using the user-valid and user-invalid custom states. These styles are only shown after the user interacts with the form control or when the form is submitted. The :valid and :invalid pseudo classes are also available, but they match even before the user has had a chance to fill out the form.


Submit Reset 
<form action="about:blank" method="get" target="_blank" class="number-input__validation-custom">
  <quiet-number-input 
    name="name"
    label="Cat videos watched"
    description="Be honest…"
    required
    style="max-width: 200px;"
    value="1000"
  ></quiet-number-input>
  <br>
  <quiet-button type="submit" variant="primary">Submit</quiet-button>
  <quiet-button type="reset">Reset</quiet-button>
</form>

<style>
  .number-input__validation-custom {
    quiet-number-input:state(user-valid) {
      outline: solid 2px var(--quiet-constructive-stroke-mid);
      outline-offset: .5rem;
    }

    quiet-number-input:state(user-invalid) {
      outline: solid 2px var(--quiet-destructive-stroke-mid);
      outline-offset: .5rem;
    }
  }
</style>

If you're using the CSS utilities, add the quiet-user-valid and quiet-user-invalid classes to any form control for automatic validation styling.

Methods Jump to heading

Number Input supports the following methods. You can obtain a reference to the element and call them like functions in JavaScript. Learn more about methods

Name Description Arguments
focus() Sets focus to the number input.
blur() Removes focus from the number input.
select() Selects all text in the number input.
stepDown() When a supported type is used, this method will decrease the number input's value by step. This is a programmatic change, so input and change events will not be emitted when this is called.
stepUp() When a supported type is used, this method will increase the number input's value by step. This is a programmatic change, so input and change events will not be emitted when this is called.
checkValidity() Checks if the form control has any restraints and whether it satisfies them. If invalid, false will be returned and the invalid event will be dispatched. If valid, true will be returned.
reportValidity() Checks if the form control has any restraints and whether it satisfies them. If invalid, false will be returned and the invalid event will be dispatched. In addition, the problem will be reported to the user. If valid, true will be returned.
setCustomValidity() Sets a custom validation message for the form control. If this message is not an empty string, then the form control is considered invalid and the specified message will be displayed to the user when reporting validity. Setting an empty string clears the custom validity state. message: string
