<template>
<div class="el_input_root">
<h2>Input 输入框</h2>
<h5>通过鼠标或键盘输入字符</h5>
<p>
Input 为受控组件，它总会显示 Vue 绑定值。<br/>
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。<br/>
不支持 v-model 修饰符
</p>
<div style="width: 300px;">
<h3>一、基础用法</h3>
<el-input v-model="input" placeholder="请输入内容"></el-input>
<h3>二、禁用状态</h3>
<h5>通过 disabled 属性指定是否禁用 input 组件</h5>
<el-input
placeholder="请输入内容"
v-model="input"
:disabled="true">
</el-input>
<h3>三、可清空</h3>
<h5>使用clearable属性即可得到一个可清空的输入框</h5>
<el-input
placeholder="请输入内容"
v-model="input"
clearable>
</el-input>
<h3>四、密码框</h3>
<h5>使用show-password属性即可得到一个可切换显示隐藏的密码框</h5>
<el-input placeholder="请输入密码" v-model="input" show-password></el-input>
</div>
<div style="width: 600px;">
<h3>五、带 icon 的输入框</h3>
<h5>带有图标标记输入类型</h5>
<h5>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。</h5>
<el-row :gutter="4" type="flex" justify="left" align="middle">
<el-col :span="3">
属性方式:
</el-col>
<el-col :span="8">
<el-input
placeholder="请选择日期"
suffix-icon="el-icon-date"
v-model="input1">
</el-input>
</el-col>
<el-col :span="8">
<el-input
placeholder="请输入内容"
prefix-icon="el-icon-search"
v-model="input2">
</el-input>
</el-col>
</el-row>
<el-row :gutter="4" type="flex" justify="left" align="middle">
<el-col :span="3">
slot 方式:
</el-col>
<el-col :span="8">
<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-col>
<el-col :span="8">
<el-input
placeholder="请输入内容"
v-model="input4">
<i slot="prefix" class="el-input__icon el-icon-search"></i>
</el-input>
</el-col>
</el-row>
<h3>六、文本域</h3>
<h5>用于输入多行文本信息，通过将 type 属性的值指定为 textarea。</h5>
<h5>文本域高度可通过 rows 属性控制</h5>
<div style="width: 300px">
<el-input
type="textarea"
:rows="2"
placeholder="请输入内容"
v-model="textarea">
</el-input>
</div>
<h3>七、可自适应文本高度的文本域</h3>
<h5>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。</h5>
<div style="width: 400px">
<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>
</div>
<h3>八、复合型输入框</h3>
<h5>可前置或后置元素，一般为标签或按钮</h5>
<h5>可通过 slot 来指定在 input 中前置或者后置内容。</h5>
<div>
<el-input placeholder="请输入内容" v-model="input5">
<template slot="prepend">Http://</template>
</el-input>
</div>
<div style="margin-top: 15px;">
<el-input placeholder="请输入内容" v-model="input6">
<template slot="append">.com</template>
</el-input>
</div>
<div style="margin-top: 15px;">
<el-input placeholder="请输入内容" v-model="input7" 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>
</div>
<div style="width: 1000px">
<h3>九、尺寸</h3>
<h5>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 medium、small 和 mini 三种尺寸。</h5>
<el-row :gutter="4">
<el-col :span="6">
<el-input
placeholder="请输入内容"
suffix-icon="el-icon-date"
v-model="input1">
</el-input>
</el-col>
<el-col :span="6">
<el-input
size="medium"
placeholder="请输入内容"
suffix-icon="el-icon-date"
v-model="input2">
</el-input>
</el-col>
<el-col :span="6">
<el-input
size="small"
placeholder="请输入内容"
suffix-icon="el-icon-date"
v-model="input3">
</el-input>
</el-col>
<el-col :span="6">
<el-input
size="mini"
placeholder="请输入内容"
suffix-icon="el-icon-date"
v-model="input4">
</el-input>
</el-col>
</el-row>
<h3>十、带输入建议</h3>
<h5>根据输入内容提供对应的输入建议</h5>
<p>
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。
</p>
<el-row>
<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"
:fetch-suggestions="querySearch"
placeholder="请输入内容"
@select="handleSelect"
></el-autocomplete>
</el-col>
<el-col :span="12">
<div class="sub-title">输入后匹配输入建议</div>
<el-autocomplete
class="inline-input"
v-model="state2"
:fetch-suggestions="querySearch"
placeholder="请输入内容"
:trigger-on-focus="false"
@select="handleSelect"
></el-autocomplete>
</el-col>
</el-row>
</div>
<h3>十一、自定义模板</h3>
<h5>可自定义输入建议的显示</h5>
<p>
使用scoped slot自定义输入建议的模板。该 scope 的参数为item，表示当前输入建议对象。
</p>
<el-autocomplete
popper-class="my-autocomplete"
v-model="state"
:fetch-suggestions="querySearch"
placeholder="请输入内容"
@select="handleSelect">
<i
class="el-icon-edit el-input__icon"
slot="suffix"
@click="handleIconClick">
</i>
<template slot-scope="{ item }">
<div class="name">{{ item.value }}</div>
<span class="addr">{{ item.address }}</span>
</template>
</el-autocomplete>
<h3>十二、远程搜索</h3>
<h5>从服务端搜索数据</h5>
<el-autocomplete
v-model="state"
:fetch-suggestions="querySearchAsync"
placeholder="请输入内容"
@select="handleSelect"
></el-autocomplete>
<h3>十三、输入长度限制</h3>
<h5>
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。
</h5>
<div style="width: 600px">
<el-row :gutter="4">
<el-col :span="12">
<el-input
type="text"
placeholder="请输入内容"
v-model="text"
maxlength="10"
show-word-limit
>
</el-input>
</el-col>
</el-row>
<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>
</div>
</div>
</template>
<style>
.el_input_root {
margin-left: 300px;
margin-right: 300px;
text-align: left;
}
.el-select .el-input {
width: 130px;
}
.input-with-select .el-input-group__prepend {
background-color: #fff;
}
.sub-title{
font-size: 14px;
text-align: left;
}
.my-autocomplete {
li {
line-height: normal;
padding: 7px;
.name {
text-overflow: ellipsis;
overflow: hidden;
}
.addr {
font-size: 12px;
color: #b4b4b4;
}
.highlighted .addr {
color: #ddd;
}
}
}
</style>
