Element-React Input 输入框

通过鼠标或键盘输入字符

基础用法

render() {
  return <Input placeholder="请输入内容" />
}

禁用状态

通过 disabled 属性指定是否禁用 input 组件

render() {
  return <Input disabled placeholder="请输入内容" />
}

带 icon 的输入框

带有图标标记输入类型

可以通过 icon 属性在 input 组件尾部增加显示图标。

handleIconClick(ev) {
}
render() {
  return (
    <Input
      icon="time"
      placeholder="请选择日期"
      onIconClick={this.handleIconClick.bind(this)}
    />
  )
}

文本域

可调整大小,用于输入多行文本信息

通过将 type 属性的值指定为 textarea。

render() {
  return (
    <Input
      type="textarea"
      autosize={{ minRows: 2, maxRows: 4}}
      placeholder="请输入内容"
    />
  )
}

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。

render() {
  return (
    <div>
      <Input
        type="textarea"
        autosize={true}
        placeholder="请输入内容"
      />
      <div style={{ margin: '20px 0' }}></div>
      <Input
        type="textarea"
        autosize={{ minRows: 2, maxRows: 4}}
        placeholder="请输入内容"
      />
    </div>
  )
}

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 prepend 和 append 来指定在 input 中前置或者后置内容。

render() {
  return (
    <div>
      <Input placeholder="请输入内容" prepend="Http://" />
      <Input placeholder="请输入内容" append=".com" />
      <Input placeholder="请输入内容" prepend={
        <Select value="">
          {
            ['餐厅名', '订单号', '用户电话'].map((item, index) => <Select.Option key={index} label={item} value={index} />)
          }
        </Select>
      } append={<Button type="primary" icon="search">搜索</Button>} />
    </div>
  )
}

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。

render() {
  return (
    <div className="inline-input">
      <Input placeholder="请输入内容" size="large" />
      <Input placeholder="请输入内容" />
      <Input placeholder="请输入内容" size="small" />
      <Input placeholder="请输入内容" size="mini" />
    </div>
  )
}

带输入建议

根据输入内容提供对应的输入建议, 依赖autoComplete

Autocomplete 是一个可带输入建议的输入框组件,

constructor(props) {
  super(props);
