# Input Number
|
|
|
|
Input numerical values with a customizable range.
|
|
|
|
## Basic usage
|
|
|
|
:::demo Bind a variable to `v-model` in `<el-input-number>` element and you are set.
|
|
|
|
input-number/basic
|
|
|
|
:::
|
|
|
|
:::tip
|
|
|
|
When inputting invalid string to the input box, input value will emit `NaN` to the upper layer as result of error
|
|
|
|
:::
|
|
|
|
## Disabled
|
|
|
|
:::demo The `disabled` attribute accepts a `boolean`, and if the value is `true`, the component is disabled. If you just need to control the value within a range, you can add `min` attribute to set the minimum value and `max` to set the maximum value. By default, the minimum value is `0`.
|
|
|
|
input-number/disabled
|
|
|
|
:::
|
|
|
|
## Steps
|
|
|
|
Allows you to define incremental steps.
|
|
|
|
:::demo Add `step` attribute to set the step.
|
|
|
|
input-number/steps
|
|
|
|
:::
|
|
|
|
## Step strictly
|
|
|
|
:::demo The `step-strictly` attribute accepts a `boolean`. if this attribute is `true`, input value can only be multiple of step.
|
|
|
|
input-number/step-strictly
|
|
|
|
:::
|
|
|
|
## Precision
|
|
|
|
:::demo Add `precision` attribute to set the precision of input value.
|
|
|
|
input-number/precision
|
|
|
|
:::
|
|
|
|
:::tip
|
|
|
|
The value of `precision` must be a non negative integer and should not be less than the decimal places of `step`.
|
|
|
|
:::
|
|
|
|
## Size
|
|
|
|
Use attribute `size` to set additional sizes with `large` or `small`.
|
|
|
|
:::demo
|
|
|
|
input-number/size
|
|
|
|
:::
|
|
|
|
## Controls Position
|
|
|
|
:::demo Set `controls-position` to decide the position of control buttons.
|
|
|
|
input-number/controlled
|
|
|
|
:::
