## 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.
|
||
:::
|
||
|
||
|
||
### Basic usage

<el-input placeholder="Please input" v-model="input"></el-input>
|
||
|
||
<script>
|
||
import { defineComponent, ref } from 'vue'
|
||
export default defineComponent ({
|
||
setup() {
|
||
return {
|
||
input: ref('')
|
||
}
|
||
}
|
||
})
|

### Input with icon
|
||
|

Add an icon to indicate input type.
|
||

:::demo To add icons in Input, you can simply use `prefix-icon` and `suffix-icon` attributes. Also, the `prefix` and `suffix` named slots works as well.
|
||
```html
|
||
<div class="demo-input-suffix">
|
||
<span class="demo-input-label">Using attributes</span>
|
||
<el-input
|
||
placeholder="Pick a date"
|
||
suffix-icon="el-icon-date"
|
||
v-model="input1">
|
||
</el-input>
|
||
<el-input
|
||
placeholder="Type something"
|
||
prefix-icon="el-icon-search"
|
||
v-model="input2">
|
||
</el-input>
|
||
</div>
|
||
<div class="demo-input-suffix">
|
||
<span class="demo-input-label">Using slots</span>
|
||
<el-input
|
||
placeholder="Pick a date"
|
||
v-model="input3">
|
||
<template #suffix>
|
||
<i class="el-input__icon el-icon-date"></i>
|
||
</template>
|
||
</el-input>
|
||
<el-input
|
||
placeholder="Type something"
|
||
v-model="input4">
|
||
<template #prefix>
|
||
<i class="el-input__icon el-icon-search"></i>
|
||
</template>
|
||
</el-input>
|
||
</div>
|
||
|
||
<style>
|
||
.demo-input-label {
|
||
display: inline-block;
|
||
width: 130px;
|
||
}
|
||
</style>
|
||
|
||
<script>
|
||
import { defineComponent, ref } from 'vue'
|
||
export default defineComponent ({
|
||
setup() {
|
||
return {
|
||
input1: ref(''),
|
||
input2: ref(''),
|
||
input3: ref(''),
|
||
input4: ref('')
|
||
}
|
||
}
|
||
})
|
||
</script>
|
||
```
|
||
:::
|
||
|
||
### Textarea
|
||
|
||
Resizable for entering multiple lines of text information. Add attribute `type="textarea"` to change `input` into native `textarea`.
|
||
|
||
:::demo Control the height by setting the `rows` prop.
|
||
|
||
```html
|
||
<el-input
|
||
type="textarea"
|
||
:rows="2"
|
||
placeholder="Please input"
|
||
v-model="textarea">
|
||
</el-input>
|
||
|
||
<script>
|
||
import { defineComponent, ref } from 'vue'
|
||
export default defineComponent ({
|
||
setup() {
|
||
return {
|
||
textarea: ref('')
|
||
}
|
||
}
|
||
})
|
||
</script>
|
||
```
|
||
:::
|
||
|
||
### Autosize Textarea
|
||
|
||
Setting the `autosize` prop for a textarea type of Input makes the height to automatically adjust based on the content. An options object can be provided to `autosize` to specify the minimum and maximum number of lines the textarea can automatically adjust.
|
||
|
||
:::demo
|
||
|
||
```html
|
||
<el-input
|
||
type="textarea"
|
||
autosize
|
||
placeholder="Please input"
|
||
v-model="textarea1">
|
||
</el-input>
|
||
<div style="margin: 20px 0;"></div>
|
||
<el-input
|
||
type="textarea"
|
||
:autosize="{ minRows: 2, maxRows: 4}"
|
||
placeholder="Please input"
|
||
v-model="textarea2">
|
||
</el-input>
|
||
|
||
<script>
|
||
import { defineComponent, ref } from 'vue'
|
||
export default defineComponent ({
|
||
setup() {
|
||
return {
|
||
textarea1: ref(''),
|
||
textarea2: ref('')
|
||
}
|
||
}
|
||
})
|
||
</script>
|
||
```

|
||
|
||
### Mixed input

### Autocomplete
|
||
|
||
You can get some recommended tips based on the current input.
|
||
|
||
:::demo Autocomplete component provides input suggestions. The `fetch-suggestions` attribute is a method that returns suggested input. In this example, `querySearch(queryString, cb)` returns suggestions to Autocomplete via `cb(data)` when suggestions are ready.
|
||
```html
|
||
<el-row class="demo-autocomplete">
|
||
<el-col :span="12">
|
||
<div class="sub-title">list suggestions when activated</div>

### Limit length
|
||
|
||
:::demo `maxlength` and `minlength` attributes of input, they declare a limit on the number of characters a user can input. 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.
