我有一个material-ui-time-picker,我想控制此输入,它很好用,但是我想编辑从键盘输入的时间,而不是单击时钟上的输入。

我的代码是:

import React, { Component } from "react";
import { TimePicker } from "material-ui-time-picker";
import { Input as Time, Dialog as Clock } from "@material-ui/core";

openDialog = () => this.setState({ isOpen: true });
  closeDialog = () => this.setState({ isOpen: false });
  handleDialogTimeChange = newValue => {
    const hours = newValue
      .getHours()
      .toString()
      .padStart(2, "0");
    const minutes = newValue
      .getMinutes()
      .toString()
      .padStart(2, "0");
    const textValue = hours + ":" + minutes;
    this.setState({ time: textValue });
  };
  handleKeyboardTimeChange = time => this.setState({ time });
  createDateFromTextValue = value => {
    const splitParts = value.split(":");
    return new Date(1970, 1, 1, splitParts[0], splitParts[1]);
  };
render() {

    return (

      <div>
        <Time
          value={this.state.time}
          onChange={this.handleKeyboardTimeChange}
          endAdornment={
            <InputAdornment position="end">
              <IconButton onClick={this.openDialog}>
                <AccessTime />
              </IconButton>
            </InputAdornment>
          }
          //}
        />
        <Clock maxWidth="xs" open={this.state.isOpen}>
          <TimePicker
            mode="24h"
            value={this.createDateFromTextValue(this.state.time)}
            onChange={this.handleDialogTimeChange}
            autoOk={true}
            cancelLabel=""
            okLabel=""
            placeholder=""
            disableUnderline={true}
          />
        </Clock>
      </div>
    );
  }

我的沙盒:https://codesandbox.io/s/vm9wm19p27

运行它时,我会得到此输入,但是当我编辑他的值时,该输入将消失。

我该如何解决?

我已经分叉了您的沙箱,并做了一些调整。尽管我尚未解决问题,但我只会向您展示当前的问题。

我修改了两行
在您的构造函数中,我添加了

this.handleKeyboardTimeChange = this.handleKeyboardTimeChange.bind(this)

和您的handleKeyboardTimeChange:

handleKeyboardTimeChange(event) {
  this.setState({ time: event.target.value });
}

这只是将状态设置为从您在那里看到的值传入的确切值。没有其他验证。
