## InputNumber

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.

```html
<template>
  <el-input-number v-model="num1" @change="handleChange" :min="1" :max="10"></el-input-number>
</template>
<script>
  export default {
    data() {
      return {
        num1: 1
      };
    },
    methods: {
      handleChange(value) {
        console.log(value)
      }
    }
  };
</script>
```
:::

### 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`.

```html
<template>
  <el-input-number v-model="num2" :disabled="true"></el-input-number>
</template>
<script>
  export default {
    data() {
      return {
        num2: 1
      }
    }
  };
</script>
```
:::

### Steps

Allows you to define incremental steps.

:::demo Add `step` attribute to set the step.

```html
<template>
  <el-input-number v-model="num3" :step="2"></el-input-number>
</template>
<script>
  export default {
    data() {
      return {
        num3: 5
      }
    }
  };
</script>
```
:::

### Size

Use attribute `size` to set additional sizes with `medium`, `small` or `mini`.

:::demo

```html
<template>
  <el-input-number v-model="num4"></el-input-number>
    <el-input-number size="medium" v-model="num5"></el-input-number>
    <el-input-number size="small" v-model="num6"></el-input-number>
    <el-input-number size="mini" v-model="num7"></el-input-number>
</template>
<script>
  export default {
    data() {
      return {
        num4: 1,
        num5: 1,
        num6: 1,
        num7: 1
      }
    }
  };
</script>
```
:::

### Controls Position

:::demo Set `controls-position` to decide the position of control buttons.
```html
<template>
  <el-input-number v-model="num8" controls-position="right" @change="handleChange" :min="1" :max="10"></el-input-number>
</template>
<script>
  export default {
    data() {
      return {
        num8: 1
      };
    },
    methods: {
      handleChange(value) {
        console.log(value);
      }
    }
  };
</script>
```
