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(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.
<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>
:::
Size
Use attribute size to set additional sizes with medium, small or mini.
:::demo
<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 controls position
<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>
