Input输入框

通过鼠标和键盘输入字符。

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

<el-input v-model="input" placeholder="请输入内容"></el-input>

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

效果图如下所示:

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="input"
  :disabled="true">
</el-input>

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

效果图如下图所示:

可清空

使用clearable属性即可得到一个可清空的输入框,输入框的右侧出现一个叉的标志,通过点击叉的标志实现清空输入框的功能。

<el-input
  placeholder="请输入内容"
  v-model="input"
  clearable>
</el-input>

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

效果图如下图所示:

密码框

使用show-password属性即可得到一个可切换显示隐藏的密码框。密码框的右侧出现一个眼睛的标识,点击这个标识会展示你输入的密码。

<el-input placeholder="请输入密码" v-model="input" show-password></el-input>

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

效果图如下所示:

带有icon的输入框

可以通过 prefix-icon和 suffix-icon属性来在input组件头部和尾部来显示图标,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>

效果图如下图所示:

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。文本域的高度可以通过rows属性来控制。

<el-input
  type="textarea"
  :rows="2"
  placeholder="请输入内容"
  v-model="textarea">
</el-input>

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

效果图如下图所示:

可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还可以指定为一个对象,指定最小行数和最大行数。

<el-input
  type="textarea"
  autosize
  placeholder="请输入内容"
  v-model="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>

效果图如下图所示:

复合型输入框

可前置后或后置元素,一般为标签和按钮。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="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>

效果图如下图所示:

尺寸

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

autocomplete是一个可带输入建议的输入框组件,fetch-suggestion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"
      :fetch-suggestions="querySearch"

输入长度限制

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>
