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
