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.

<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() {
    		console.log(this.num1)
    	}
    }
  };
</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.

<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.

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