<el-input
  placeholder="请输入内容"
  v-model="input">
</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="input1"
  :disabled="true">
</el-input>

<script>
export default {
  data() {
    return {
      input1: ''
    }
  }
}
</script>

:::

::: demo 可以通过 icon 属性在 input 组件尾部增加显示图标。

<el-input
  placeholder="请选择日期"
  icon="time"
  v-model="input2"
  @click="handleIconClick">
</el-input>

<script>
export default {
  data() {
    return {
      input2: ''
    }
  },
  methods: {
    handleIconClick(ev) {
      console.log(ev);
    }
  }
}
</script>

:::

文本域

可调整大小,用于输入多行文本信息

::: demo 通过将 type 属性的值指定为 textarea。

<el-input
  type="textarea"
  :autosize="{ minRows: 2, maxRows: 4}"
  placeholder="请输入内容"
  v-model="textarea">
</el-input>

<script>
export default {

    return {
      textarea: ''
    }
  }
}
</script>

:::

复合型输入框

::: demo 可通过 slot 来指定在 input 中前置或者后置内容。

<template>
  <el-input placeholder="请输入内容" v-model="input3">
    <template slot="prepend">Http://</template>
  </el-input>
  <el-input placeholder="请输入内容" v-model="input4">
    <template slot="append">.com</template>
  </el-input>
  <el-input placeholder="请输入内容" v-model="input5" style="width: 300px;">
    <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="search"></el-button>
  </el-input>
</template>

<style>
.el-select .el-input {
  width: 100px;
}
</style>

<script>
export default {
  data() {
    return {
      input3: '',
      input4: '',
      input5: '',
      select: ''
    }
  }
}
</script>

:::

::: 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>
  <el-input
    class="inline-input"
    size="large"
    placeholder="请输入内容"
    v-model="input6">
  </el-input>
  <el-input
    class="inline-input"
    placeholder="请输入内容"
    v-model="input7">
  </el-input>
  <el-input
    class="inline-input"
    size="small"
    placeholder="请输入内容"
    v-model="input8">
  </el-input>
  <el-input
    class="inline-input"
    size="mini"
    placeholder="请输入内容"
    v-model="input9">
  </el-input>
</div>

<script>
export default {
  data() {
    return {
      input6: '',
      input7: '',
      input8: '',
      input9: ''
    }
  }
}
</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="border-grid">
  <el-col :span="12" class="tac">
    <div class="text">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" class="tac">
    <div class="text">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>
<script>
  export default {
    data() {
      return {
        restaurants: [],
        state1: '',
        state2: ''
      };
    },
    methods: {
      querySearch(queryString, cb) {
        var restaurants = this.restaurants;
        var results = queryString ? restaurants.filter(this.createFilter(queryString)) : restaurants;
        // 调用 callback 返回建议列表的数据
        cb(results);
      },
      createFilter(queryString) {
