InputNumber

InputNumber is an input component to provide numerical input.


import InputNumber from 'primevue/inputnumber';

InputNumber is used as a controlled input with v-model property.



<InputNumber v-model="value1" inputId="integeronly" />
<InputNumber v-model="value2" inputId="withoutgrouping" :useGrouping="false" />
<InputNumber v-model="value3" inputId="minmaxfraction" :minFractionDigits="2" :maxFractionDigits="5" />
<InputNumber v-model="value4" inputId="minmax" :min="0" :max="100" />

Localization information such as grouping and decimal symbols are defined with the locale property which defaults to the user locale.



<InputNumber v-model="value1" inputId="locale-user" :minFractionDigits="2" />
<InputNumber v-model="value2" inputId="locale-us" locale="en-US" :minFractionDigits="2" />
<InputNumber v-model="value3" inputId="locale-german" locale="de-DE" :minFractionDigits="2" />
<InputNumber v-model="value4" inputId="locale-indian" locale="en-IN" :minFractionDigits="2" />

Monetary values are enabled by setting mode property as currency. In this setting, currency property also needs to be defined using ISO 4217 standard such as "USD" for the US dollar.



<InputNumber v-model="value1" inputId="currency-us" mode="currency" currency="USD" locale="en-US" />
<InputNumber v-model="value2" inputId="currency-germany" mode="currency" currency="EUR" locale="de-DE" />
<InputNumber v-model="value3" inputId="currency-india" mode="currency" currency="INR" currencyDisplay="code" locale="en-IN" />
<InputNumber v-model="value4" inputId="currency-japan" mode="currency" currency="JPY" locale="jp-JP" />

Custom texts e.g. units can be placed before or after the input section with the prefix and suffix properties.



<InputNumber v-model="value1" inputId="mile" suffix=" mi" />
<InputNumber v-model="value2" inputId="percent" prefix="%" />
<InputNumber v-model="value3" inputId="expiry" prefix="Expires in " suffix=" days" />
<InputNumber v-model="value4" inputId="temperature" prefix="&uarr; " suffix="℃" :min="0" :max="40" />

Spinner buttons are enabled using the showButtons property and layout is defined with the buttonLayout.



<InputNumber v-model="value1" inputId="stacked-buttons" showButtons mode="currency" currency="USD" />
<InputNumber v-model="value2" inputId="minmax-buttons" mode="decimal" showButtons :min="0" :max="100" />
<InputNumber v-model="value3" inputId="horizontal-buttons" showButtons buttonLayout="horizontal" :step="0.25"
    decrementButtonClass="p-button-danger" incrementButtonClass="p-button-success" incrementButtonIcon="pi pi-plus" decrementButtonIcon="pi pi-minus"
    mode="currency" currency="EUR" />

Buttons can also placed vertically by setting buttonLayout as vertical.



<InputNumber v-model="value" showButtons buttonLayout="vertical" style="width: 4rem"
    decrementButtonClassName="p-button-secondary" incrementButtonClassName="p-button-secondary" incrementButtonIcon="pi pi-plus" decrementButtonIcon="pi pi-minus" />

A floating label appears on top of the input field when focused.



<span class="p-float-label">
    <InputNumber id="number-input" v-model="value" />
    <label for="number-input">Number</label>
</span>

Invalid state style is added using the p-invalid class to indicate a failed validation.



<InputNumber v-model="value" class="p-invalid" mode="decimal" :minFractionDigits="2" />

            <InputNumber id="year" v-model="value" :class="{ 'p-invalid': errorMessage }" :useGrouping="false" aria-describedby="number-error" />
            <small class="p-error" id="number-error">{{ errorMessage || (errors.length > 0 ? errors : '&nbsp;') }}</small>
            <Button type="submit" label="Submit" />
        </form>
