onFocus 和 onBlur 不会在反应中呈现

onFocus and onBlur does not render in react

我有以下代码

<ElementsBasket
  name="nextActionDate"
  data={this.props.newLead.get("actions").get("nextActionDate")}
>
  <div className="form-group">
    <span className="glyphicon glyphicon-calendar">Calendar </span>
    <span className="glyphicon glyphicon-triangle-bottom"></span>

    <input
      type="text"
      className="form-control"
      onFocus={(this.type = "date")}
      onBlur={(this.type = "text")}
      placeholder="Enter your date here."
      value={this.props.newLead.get("actions").get("nextActionDate")}
      onChange={onFieldChanged.bind(this, "actions.nextActionDate")}
    />
  </div>
</ElementsBasket>;

在输入标签中,我试图让一个占位符文本默认出现在输入字段中,当点击时我希望将类型更改为日期。问题似乎出在单击 Chrome 上的检查元素时。它不会显示 onFocusonBlur.

P/S: 甚至 onClick 似乎也有同样的问题

这是您要找的吗?

var Foo = React.createClass({
  getInitialState: function () {

    return {
      type: 'text'
    };
  },
  onFocus: function () {

    this.setState({
      type: 'date'
    });
  },
  onBlur: function () {

    this.setState({
      type: 'text'
    });
  },
  render: function () {

    return(
      <input 
        type={ this.state.type } 
        onFocus={ this.onFocus } 
        onBlur={ this.onBlur } 
        placeholder="Enter your date here."
      />
    )
  }
});

React.render(<Foo/>, document.body);

正如我在上面评论的那样,render 方法第一次触发,之后在每次状态更改时触发(如果 shouldComponentRender returns true 如果它已实现):
