# Input
|
|
|
|
Input data using mouse or keyboard.
|
|
|
|
:::warning
|
|
|
|
Input is a controlled component, it **always shows Vue binding value**.
|
|
|
|
Under normal circumstances, `input` event should be handled. Its handler should update component's binding value (or use `v-model`). Otherwise, input box's value will not change.
|
|
|
|
Do not support `v-model` modifiers.

The "number of characters" is measured using JavaScript string length.Setting the `maxlength` prop for a text or textarea type of Input can limit the length of input value, allows you to show word count by setting `show-word-limit` to `true` at the same time.
