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="num" @change="handleChange" :min="1" :max="10"></el-input-number>
</template>
<script>
export default {
data() {
return {
num: 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="num" :disabled="true"></el-input-number>
</template>
<script>
export default {
data() {
return {
num: 1
}
}
};
</script>
:::
Steps
Allows you to define incremental steps.
:::demo Add step attribute to set the step.
<template>
<el-input-number v-model="num" :step="2"></el-input-number>
</template>
<script>
export default {
data() {
return {
num: 5
}
}
};
</script>
:::
Step strictly
:::demo The step-strictly attribute accepts a boolean. if this attribute is true, input value can only be multiple of step.
<template>
<el-input-number v-model="num" :step="2" step-strictly></el-input-number>
</template>
<script>
export default {
data() {
return {
num: 2
}
}
};
</script>
:::
Precision
:::demo Add precision attribute to set the precision of input value.
<template>
<el-input-number v-model="num" :precision="2" :step="0.1" :max="10"></el-input-number>
</template>
<script>
export default {
data() {
return {
num: 1
}
}
};
</script>
:::
:::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 medium, small or mini.
:::demo
<template>
<el-input-number v-model="num1"></el-input-number>
<el-input-number size="medium" v-model="num2"></el-input-number>
<el-input-number size="small" v-model="num3"></el-input-number>
<el-input-number size="mini" v-model="num4"></el-input-number>
</template>
<script>
export default {
data() {
return {
num1: 1,
num2: 1,
num3: 1,
num4: 1
}
}
};
</script>
:::
Controls Position
:::demo Set controls-position to decide the position of control buttons.
<template>
<el-input-number v-model="num" controls-position="right" @change="handleChange" :min="1" :max="10"></el-input-number>
</template>
<script>
export default {
data() {
return {
num: 1
};
},
methods: {
handleChange(value) {
console.log(value);
}
}
};
</script>
