基础用法
<el-input v-model="input" placeholder="请输入内容"></el-input>
<script>
export default {
data() {
return {
input: ''
}
}
}
</script>禁用状态
通过 disabled 属性指定是否禁用 input 组件
<el-input
placeholder="请输入内容"
v-model="input1"
:disabled="true">
</el-input>
<script>
export default {
data() {
return {
input1: ''
}
}
}
</script>可清空
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="input10"
clearable>
</el-input>
<script>
export default {
data() {
return {
input10: ''
}
}
}
</script>带 icon 的输入框
带有图标标记输入类型
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="input2">
</el-input>
<el-input
placeholder="请输入内容"
prefix-icon="el-icon-search"
v-model="input21">
</el-input>
</div>
<div class="demo-input-suffix">
slot 方式：
<el-input
placeholder="请选择日期"
v-model="input22">
<i slot="suffix" class="el-input__icon el-icon-date"></i>
</el-input>
<el-input
placeholder="请输入内容"
v-model="input23">
<i slot="prefix" class="el-input__icon el-icon-search"></i>
</el-input>
</div>
<script>
export default {
data() {
return {
input2: '',
input21: '',
input22: '',
input23: ''
}
}
}
</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。
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。
<el-input
type="textarea"
autosize
placeholder="请输入内容"
v-model="textarea2">
</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="textarea3">
</el-input>
<script>
export default {
data() {
return {
textarea2: '',
textarea3: ''
}
}
}
</script>复合型输入框
可前置或后置元素，一般为标签或按钮
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="input3">
<template slot="prepend">Http://</template>
</el-input>
</div>
<div style="margin-top: 15px;">
<el-input placeholder="请输入内容" v-model="input4">
<template slot="append">.com</template>
</el-input>

<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() {

</script>带输入建议
根据输入内容提供对应的输入建议
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">
