Quick Start

import { TimePickerComponent } from '@syncfusion/ej2-react-calendars';
import * as React from 'react';
import '@syncfusion/ej2-base/styles/material3.css';
import '@syncfusion/ej2-calendars/styles/material3.css';

function App() {
  const [selectedTime, setSelectedTime] = React.useState(new Date('1/1/2018 9:00 AM'));

  const handleChange = (e: any) => {
    setSelectedTime(e.value);
  };

  return (
    <div style={{ padding: '20px' }}>
      <h2>Select Time</h2>
      <TimePickerComponent
        value={selectedTime}
        change={handleChange}
        placeholder="Select a time"
      />
      <p>Selected: {selectedTime ? selectedTime.toLocaleTimeString() : 'None'}</p>
    </div>
  );
}

export default App;

Common Patterns

Pattern 1: Time Picker with Min/Max Constraints

import { TimePickerComponent } from '@syncfusion/ej2-react-calendars';
import * as React from 'react';

function AppointmentScheduler() {
  const [appointmentTime, setAppointmentTime] = React.useState(new Date('1/1/2018 9:00 AM'));

  const minTime = new Date('1/1/2018 8:00 AM');
  const maxTime = new Date('1/1/2018 5:00 PM');

  return (
    <div>
      <h3>Select Appointment Time (8 AM - 5 PM)</h3>
      <TimePickerComponent
        value={appointmentTime}
        min={minTime}
        max={maxTime}
        step={30}
        change={(e: any) => setAppointmentTime(e.value)}
        placeholder="Choose time"
      />
    </div>
  );
}

export default AppointmentScheduler;

Pattern 2: Form with Time Picker Submission

import { TimePickerComponent } from '@syncfusion/ej2-react-calendars';
import { ButtonComponent } from '@syncfusion/ej2-react-buttons';
import * as React from 'react';

function ScheduleForm() {
  const [formData, setFormData] = React.useState({
    startTime: new Date('1/1/2018 9:00 AM'),
    endTime: new Date('1/1/2018 5:00 PM'),
  });

  const handleSubmit = (e: React.FormEvent) => {
    e.preventDefault();
    console.log('Schedule data:', {
      startTime: formData.startTime?.toLocaleTimeString(),
      endTime: formData.endTime?.toLocaleTimeString(),
    });
  };

  return (
    <form onSubmit={handleSubmit}>
      <h3>Schedule Meeting</h3>
      
      <label>Start Time:</label>
      <TimePickerComponent
        value={formData.startTime}
        change={(e: any) => setFormData(prev => ({ ...prev, startTime: e.value }))}
      />

      <label style={{ marginTop: '10px' }}>End Time:</label>
      <TimePickerComponent
        value={formData.endTime}
        min={formData.startTime}
        change={(e: any) => setFormData(prev => ({ ...prev, endTime: e.value }))}
      />

      <ButtonComponent type="submit" isPrimary={true} style={{ marginTop: '15px' }}>
        Schedule
      </ButtonComponent>
    </form>
  );
}

export default ScheduleForm;

Pattern 3: Time Picker with Custom Format

import { TimePickerComponent } from '@syncfusion/ej2-react-calendars';
import * as React from 'react';

function TimeFormatDemo() {
  const [time12hr, setTime12hr] = React.useState(new Date('1/1/2018 2:30 PM'));
  const [time24hr, setTime24hr] = React.useState(new Date('1/1/2018 14:30'));

  return (
    <div style={{ padding: '20px' }}>
      <div>
        <h4>12-Hour Format (hh:mm a)</h4>
        <TimePickerComponent
          value={time12hr}
          format="hh:mm a"
          change={(e: any) => setTime12hr(e.value)}
        />
        <p>Value: {time12hr?.toLocaleTimeString('en-US', { hour12: true })}</p>
      </div>

      <div style={{ marginTop: '20px' }}>
        <h4>24-Hour Format (HH:mm)</h4>
        <TimePickerComponent
          value={time24hr}
          format="HH:mm"
          change={(e: any) => setTime24hr(e.value)}
        />
        <p>Value: {time24hr?.toLocaleTimeString('en-US', { hour12: false })}</p>
      </div>
    </div>
  );
}

export default TimeFormatDemo;

Pattern 4: Event Handling and State Management

import { TimePickerComponent } from '@syncfusion/ej2-react-calendars';
import * as React from 'react';

function EventTrackingExample() {
  const [selectedTime, setSelectedTime] = React.useState<Date | null>(null);
  const [eventLog, setEventLog] = React.useState<string[]>([]);

  const handleChange = (e: any) => {
    setSelectedTime(e.value);
    setEventLog(prev => [...prev, `Changed: ${e.value?.toLocaleTimeString()}`]);
  };

  const handleOpen = (e: any) => {
    setEventLog(prev => [...prev, 'Popup opened']);
  };

  const handleClose = (e: any) => {
    setEventLog(prev => [...prev, 'Popup closed']);
  };

  return (
    <div style={{ padding: '20px' }}>
      <h3>Time Picker with Event Tracking</h3>
      <TimePickerComponent
        value={selectedTime}
        change={handleChange}
        open={handleOpen}
        close={handleClose}
        placeholder="Select time to track events"
      />

      <div style={{ marginTop: '20px', padding: '10px', border: '1px solid #ccc' }}>
        <h4>Event Log:</h4>
        <ul>
          {eventLog.map((event, idx) => (
            <li key={idx}>{event}</li>
          ))}
        </ul>
      </div>
    </div>
  );
}

export default EventTrackingExample;

Pattern 5: Masked Time Input

import { TimePickerComponent } from '@syncfusion/ej2-react-calendars';
import * as React from 'react';

function MaskedTimePickerExample() {
  const [maskedTime, setMaskedTime] = React.useState(new Date('1/1/2018 10:30 AM'));

  return (
    <div style={{ padding: '20px' }}>
      <h3>Masked Time Input</h3>
      <TimePickerComponent
        value={maskedTime}
        enableMask={true}
        format="hh:mm a"
        maskPlaceholder={{
          hour: 'HH',
          minute: 'MM',
          second: 'SS',
        }}
        change={(e: any) => setMaskedTime(e.value)}
        placeholder="Enter time (HH:MM AM/PM)"
      />
      <p>Masked input helps users enter time in correct format</p>
    </div>
  );
}

export default MaskedTimePickerExample;
