Input 输入框
通过鼠标或键盘输入字符
:::warning Input 为受控组件,它总会显示 Vue 绑定值。
通常情况下,应当处理 input
事件,并更新组件的绑定值(或使用v-model
)。否则,输入框内显示的值将不会改变。
不支持 v-model
修饰符。
:::
基础用法
:::demo
<el-input v-model="input" placeholder="请输入内容"></el-input>
<script>
export default {
data() {
return {
input: ''
}
}
}
</script>
:::
禁用状态
:::demo 通过 disabled
属性指定是否禁用 input 组件
<el-input
placeholder="请输入内容"
v-model="input"
:disabled="true">
</el-input>
<script>
export default {
data() {
return {
input: ''
}
}
}
</script>
:::
可清空
:::demo 使用clearable
属性即可得到一个可清空的输入框
<el-input
placeholder="请输入内容"
v-model="input"
clearable>
</el-input>
<script>
export default {
data() {
return {
input: ''
}
}
}
</script>
:::
密码框
:::demo 使用show-password
属性即可得到一个可切换显示隐藏的密码框
<el-input placeholder="请输入密码" v-model="input" show-password></el-input>
<script>
export default {
data() {
return {
input: ''
}
}
}
</script>
:::
带 icon 的输入框
带有图标标记输入类型
:::demo 可以通过 prefix-icon
和 suffix-icon
属性在 input 组件首部和尾部增加显示图标,也可以通过 slot 来放置图标。
<div class="demo-input-suffix">
属性方式:
<el-input
placeholder="请选择日期"
suffix-icon="el-icon-date"
v-model="input1">
</el-input>
<el-input
placeholder="请输入内容"
prefix-icon="el-icon-search"
v-model="input2">
</el-input>
</div>
<div class="demo-input-suffix">
slot 方式:
<el-input
placeholder="请选择日期"
v-model="input3">
<i slot="suffix" class="el-input__icon el-icon-date"></i>
</el-input>
<el-input
placeholder="请输入内容"
v-model="input4">
<i slot="prefix" class="el-input__icon el-icon-search"></i>
</el-input>
</div>
<script>
export default {
data() {
return {
input1: '',
input2: '',
input3: '',
input4: ''
}
}
}
</script>
:::
文本域
用于输入多行文本信息,通过将 type
属性的值指定为 textarea。
:::demo 文本域高度可通过 rows
属性控制
<el-input
type="textarea"
:rows="2"
placeholder="请输入内容"
v-model="textarea">
</el-input>
<script>
export default {
data() {
return {
textarea: ''
}
}
}
</script>
:::
可自适应文本高度的文本域
通过设置 autosize
属性可以使得文本域的高度能够根据文本内容自动进行调整,并且 autosize
还可以设定为一个对象,指定最小行数和最大行数。
:::demo
<el-input
type="textarea"
autosize
placeholder="请输入内容"
v-model="textarea1">
</el-input>
<div style="margin: 20px 0;"></div>
<el-input
type="textarea"
:autosize="{ minRows: 2, maxRows: 4}"
placeholder="请输入内容"
v-model="textarea2">
</el-input>
<script>
export default {
data() {
return {
textarea1: '',
textarea2: ''
}
}
}
</script>
:::
复合型输入框
可前置或后置元素,一般为标签或按钮
:::demo 可通过 slot 来指定在 input 中前置或者后置内容。
<div>
<el-input placeholder="请输入内容" v-model="input1">
<template slot="prepend">Http://</template>
</el-input>
</div>
<div style="margin-top: 15px;">
<el-input placeholder="请输入内容" v-model="input2">
<template slot="append">.com</template>
</el-input>
</div>
<div style="margin-top: 15px;">
<el-input placeholder="请输入内容" v-model="input3" class="input-with-select">
<el-select v-model="select" slot="prepend" placeholder="请选择">
<el-option label="餐厅名" value="1"></el-option>
<el-option label="订单号" value="2"></el-option>
<el-option label="用户电话" value="3"></el-option>
</el-select>
<el-button slot="append" icon="el-icon-search"></el-button>
</el-input>
</div>
<style>
.el-select .el-input {
width: 130px;
}
.input-with-select .el-input-group__prepend {
background-color: #fff;
}
</style>
<script>
export default {
data() {
return {
input1: '',
input2: '',
input3: '',
select: ''
}
}
}
</script>
:::
尺寸
:::demo 可通过 size
属性指定输入框的尺寸,除了默认的大小外,还提供了 large、small 和 mini 三种尺寸。
<div class="demo-input-size">
<el-input
placeholder="请输入内容"
suffix-icon="el-icon-date"
v-model="input1">
</el-input>
<el-input
size="medium"
placeholder="请输入内容"
suffix-icon="el-icon-date"
v-model="input2">
</el-input>
<el-input
size="small"
placeholder="请输入内容"
suffix-icon="el-icon-date"
v-model="input3">
</el-input>
<el-input
size="mini"
placeholder="请输入内容"
suffix-icon="el-icon-date"
v-model="input4">
</el-input>
</div>
<script>
export default {
data() {
return {
input1: '',
input2: '',
input3: '',
input4: ''
}
}
}
</script>
:::
带输入建议
根据输入内容提供对应的输入建议
:::demo autocomplete 是一个可带输入建议的输入框组件,fetch-suggestions
是一个返回输入建议的方法属性,如 querySearch(queryString, cb),在该方法中你可以在你的输入建议数据准备好时通过 cb(data) 返回到 autocomplete 组件中。
<el-row class="demo-autocomplete">
<el-col :span="12">
<div class="sub-title">激活即列出输入建议</div>
<el-autocomplete
class="inline-input"
v-model="state1"

<el-col :span="12">
<div class="sub-title">输入后匹配输入建议</div>
<el-autocomplete

输入长度限制
:::demo maxlength
和 minlength
是原生属性,用来限制输入框的字符长度,其中字符长度是用 Javascript 的字符串长度统计的。对于类型为 text
或 textarea
的输入框,在使用 maxlength
属性限制最大输入长度的同时,可通过设置 show-word-limit
属性来展示字数统计。
<el-input
type="text"
placeholder="请输入内容"
v-model="text"
maxlength="10"
show-word-limit
>
</el-input>
<div style="margin: 20px 0;"></div>
<el-input
type="textarea"
placeholder="请输入内容"
v-model="textarea"
maxlength="30"
show-word-limit
>
</el-input>
<script>
export default {
data() {
return {
text: '',
textarea: ''
}
}
}
</script>
