jquery ui timepicker onChange Event

// Define the jQuery UI timepicker event handler function
function timepicker_onChange(event) {
  // Retrieve the selected time value from the timepicker
  var selected_time = $(this).timepicker('getTime');
  
  // Do something with the selected time value (e.g., update an input field or display a message)
  update_time_input(selected_time);
}

// Update the time input field when the timepicker changes
function update_time_input(time) {
  // Get the input field element
  var input_field = $('#time-input');
  
  // Update the input field with the selected time value
  input_field.val(time.format('HH:mm:ss'));
}

This code defines a jQuery UI timepicker event handler function called timepicker_onChange that is called when the timepicker is changed. It retrieves the selected time value from the timepicker and then performs some action, such as updating an input field or displaying a message.

The update_time_input function is called when the timepicker is changed, and it gets the input field element and updates it with the selected time value using the format method of the time object, which returns a string in the format "HH:mm:ss".

Note that this code assumes that the HTML elements for the timepicker and input field already exist on the page. You can modify the code to fit your specific needs, such as by specifying the input field element differently or by using a different format for the time value.
