QUESTION

JS Alarmclock needs adjustment

Asked 2022-Mar-29 at 10:24

I'm trying to set an alarmclock for the webapp I'm creating with Django. To do so, I followed some tutorials and adjusted the code for my needs and all. It works. My problem is, I want to set the time and date, manually, with the variables I get from Django views (I passed the hour and min variables into my HTML file). Here is my alarm.html file:

{% extends 'mainapp_hf/base.html' %}
{% block content %}

 {{ js_hour  }}


      <div style="width: 100%; display: flex; justify-content: center; ">

          <div id="clock"></div>


    <script> 
        const display = document.getElementById('clock');
        
        
        const audio = new Audio('https://assets.mixkit.co/sfx/preview/mixkit-alarm-digital-clock-beep-989.mp3');
        audio.loop = true;
        let alarmTime = null;
        let alarmTimeout = null;
        
        
        function updateTime() {
            const date = new Date();
        
            const hour = formatTime(date.getHours());
            const minutes = formatTime(date.getMinutes());
            const seconds = formatTime(date.getSeconds());
        
        
        
            display.innerText=`${hour} : ${minutes} : ${seconds}`
        }
        
        function formatTime(time) {
            if ( time < 10 ) {
                return '0' + time;
            }
            return time;
        }
        
        function setAlarmTime(value) {
        
            alarmTime = value;
        }
        
        function setAlarm() {
            if(alarmTime) {
                const current = new Date();
                const timeToAlarm = new Date(alarmTime);
        
                if (timeToAlarm > current) {
                    const timeout = timeToAlarm.getTime() - current.getTime();
                    alarmTimeout = setTimeout(() => audio.play(), timeout);
                    setTimeout(clearAlarm, timeout + 5000);
                    alert( value );
                }
            }
        }
        
        function clearAlarm() {
            audio.pause();
            if (alarmTimeout) {
                clearTimeout(alarmTimeout);
                alert("value");
            }

I'm newborn JS learner. I have no clue how to go further at this point, just to understand and adjust this current code took me hours. For starter, I'm okay to ignore all other variables (like date, minute, second). Can anyone guide me to just to get the realtime hour and then compare it with my django variable {{ js_hour }} (data type is number, and lets say its equal to 15) and if they match, ring the sound (regardless of date or minute).

The variable "value" in setAlarmTime, is the user input that is being submitted via a form, but since I dont want that form anymore, (instead, I want to use my django variables), I didnt include that part of the code here.

The form user normally submits, has HTML input field that has type of "datetime-local". I tried to write my js_hour python variable in this format, like following

views.py

js_hour = "2022-03-29T11:00"

and then adjusted following part:

alarm.html

        function setAlarmTime(value) {
        
            alarmTime = {{ js_hour  }};
        }

Thought this should do the trick. When I dont play around and just get the user input, type of alarmTime is [object HTMLInputElement], and when I replace it with {{ js_hour }}, data type turns into an object. And no alarm rings, code stop working.

Any suggestions?

Just do

setAlarmTime("{{ js_time }}");
setAlarm()

and remove the alerts - you do not have a var called value

const display = document.getElementById('clock');
const audio = new Audio('https://assets.mixkit.co/sfx/preview/mixkit-alarm-digital-clock-beep-989.mp3');
audio.loop = true;
let alarmTime = null;
let alarmTimeout = null;


function updateTime() {
  const date = new Date();

  const hour = formatTime(date.getHours());
  const minutes = formatTime(date.getMinutes());
  const seconds = formatTime(date.getSeconds());
  display.innerText = `${hour} : ${minutes} : ${seconds}`
}

function formatTime(time) {
  if (time < 10) {
    return '0' + time;
  }
  return time;
}

function setAlarmTime(value) {
  alarmTime = value;
}

function setAlarm() {
  if (alarmTime) {
    const current = new Date();
    const timeToAlarm = new Date(alarmTime);
console.log(timeToAlarm)
    if (timeToAlarm > current) {
      const timeout = timeToAlarm.getTime() - current.getTime();
      alarmTimeout = setTimeout(() => audio.play(), timeout);
      setTimeout(clearAlarm, timeout + 5000);
    }
    else { console.log("time has passed") }
  }
}

function clearAlarm() {
  audio.pause();
  if (alarmTimeout) {
    clearTimeout(alarmTimeout);
    console.log("Cleared");
  }
}
setAlarmTime("2022-03-29T12:23"); // "{{ js_time }}";
// debug
let d = new Date()
d.setSeconds(d.getSeconds() + 10)
setAlarmTime(d.toString())
// end debug

setAlarm()
setInterval(updateTime, 1000);

QUESTION

how to pass uncertain parameter to method flutter

Asked 2022-Jan-29 at 10:49

I have a method like following:

  void reverseWeekdayStatus({alarmClock,sundayIsSelected}){
    alarmClock.sundayIsSelected = !alarmClock.sundayIsSelected ?? false;
    update();
  }

alarmClock is a model:

class AlarmClock {
  bool sundayIsSelected;
  bool mondayIsSelected;
  bool tuesdaySelected;
  bool wednesdayIsSelected;
  bool thursdayIsSelected;
  bool fridayIsSelected;
  bool saturdayIsSelected;

  AlarmClock({
    this.sundayIsSelected = false,
    this.mondayIsSelected = false,
    this.tuesdaySelected = false,
    this.wednesdayIsSelected = false,
    this.thursdayIsSelected = false,
    this.fridayIsSelected = false,
    this.saturdayIsSelected = false,
  });
}

so for this method I want to not just sundayIsSelected also the rest like mondayIsSelected could be reversed if I implement this method, what I did is following:

  void reverseWeekdayStatus({alarmClock,whichDay}){
    alarmClock.whichDay = !alarmClock.whichDay ?? false;
    update();
  }

And pass mondayIsSelected for example to whichDay, and then I got an error since whichDay does not exist in alarmClock, another way I thought is to create separate methods like from monday to sunday, is there a smarter way to do this job? thanks!

ANSWER

Answered 2022-Jan-28 at 10:02

class AlarmClock {
  bool sundayIsSelected;

  AlarmClock({
    this.sundayIsSelected = false,
  });
}

On current mode, you are providing default for each field. If you don't pass any value for sundayIsSelected it will get default value false. But sundayIsSelected is not nullable. It can't be null.

Therefore, alarmClock.sundayIsSelected ?? false will never get false.

To reverse, you just like to change the value then do

 void reverseWeekdayStatus({
    alarmClock,
  }) {
    alarmClock.sundayIsSelected = !alarmClock.sundayIsSelected;
   ...
  }

It will switch the bool when ever gets call. You can do conditional state on update case, and it is an optional parameter with default value.

void reverseWeekdayStatus({alarmClock, bool switchSundayState = false}) {
  if (switchSundayState) {
    alarmClock.sundayIsSelected = !alarmClock.sundayIsSelected;
  }
}

Another technic is using copyWith constructor, it is nullable (optional) named constructor, use current value if we don't pass value for field.

class AlarmClock {
  final bool sundayIsSelected;

  AlarmClock({
    this.sundayIsSelected = false,
  });

  AlarmClock copyWith({
    bool? sundayIsSelected,
  }) {
    return AlarmClock(
      sundayIsSelected: sundayIsSelected ?? this.sundayIsSelected,
    );
  }
}

And use cases

alarmClock = alarmClock.copyWith(sundayIsSelected: true);

QUESTION

The getter 'sundayIsSelected' was called on null. Receiver: null Tried calling: sundayIsSelected

Asked 2022-Jan-25 at 17:24

here I created a model, and try to use the model in the page, but I get an error:

The getter 'sundayIsSelected' was called on null.
Receiver: null
Tried calling: sundayIsSelected

I set the sundayIsSelected in AlarmClock default value is false, why in the TimePickerPage there is still null? thanks!

Here is model code:

class AlarmClock {
  bool sundayIsSelected;

//I also tried followings:
//bool sundayIsSelected = false;

  AlarmClock({
    this.sundayIsSelected = false,
  });
}

here is my page code.

class TimePickerPage extends StatefulWidget {
  final AlarmClock alarmClock;

  const TimePickerPage({Key key, this.alarmClock}) : super(key: key);

  @override
  _TimePickerPageState createState() => _TimePickerPageState();
}

class _TimePickerPageState extends State<TimePickerPage> {

  bool sundayIsSelected;

@override
  void initState() {
    sundayIsSelected = widget.alarmClock.sundayIsSelected;
}
  Widget build(BuildContext context) {
    Text(sundayIsSelected),
 }
}

ANSWER

Answered 2022-Jan-25 at 17:24

It is possible for alarmClock to be null, I will recommend adding required parameter on constructor and properly add others annotations.


class TimePickerPage extends StatefulWidget {
  final AlarmClock alarmClock;

  const TimePickerPage({Key? key, required this.alarmClock}) : super(key: key);

  @override
  _TimePickerPageState createState() => _TimePickerPageState();
}

class _TimePickerPageState extends State<TimePickerPage> {
  late bool sundayIsSelected;

  @override
  void initState() {
    sundayIsSelected = widget.alarmClock.sundayIsSelected;
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return Text(sundayIsSelected.toString());
  }
}

And use it like

final alarmClock = AlarmClock(),
....
TimePickerPage(
  alarmClock: alarmClock, 
),
// or 
TimePickerPage(
  alarmClock: AlarmClock(),
)
...

QUESTION

Attempt to make a timer in python, where is the error?

Asked 2021-Jun-17 at 17:44

I'm quite new to python programming and I was attempting to create a countdown timer. I wrote down the following code for the timer but it's not working. Can you help in figuring out where the error is? (I did a bit of research on this site and found a few questions relating to timers. In fact most of this code is written based on another answer but I did some changes to it because that code was for a clock and I'm trying to make a timer.)

from tkinter import *
from tkinter import messagebox

class alarmclock():
    
    def __init__(self):
        self.alarm = Tk()
        self.l0 = Label(self.alarm, text = '----------- Alarm clock 1 -----------')
        self.l1 = Label(self.alarm, text = 'Please type in the time:')
        self.e0 = Entry(self.alarm)
        self.l2 = Label(self.alarm)
        self.b0 = Button(self.alarm, text = 'Start countdown', command = lambda: self.timer)
        self.l0.grid(row = 0, column = 0, columnspan = 2)
        self.l1.grid(row = 1, column = 0, padx = 10, pady =5)
        self.e0.grid(row = 1, column = 1, padx = 10)
        self.l2.grid(row = 2, column = 1, padx = 10)
        self.b0.grid(row = 3, column = 0, columnspan = 2, pady = 5)
        self.alarm.mainloop()
    
    def timer(self):
        self.b = float(self.e0.get())
        self.l2.configure(text = str(self.b))
        self.b-=1
        if self.b != 0:
            self.alarm.after(1000, self.timer)
        if self.b == 0:
            self.l2.configure(text = str(self.b))
            self.messagebox.showwarning('Alarm Clock', 'Time\'s up!')

ANSWER

Answered 2021-Jun-17 at 15:55

Firstly to answer your main question: tkinter requires a function that it can call if you press the button, so you have to supply the function so tkinter can call it, here you are are supplying a function with lambda that returns the function, you can want to call. So when you press the button the lambda function is called and the function(you wanted to call) is returned, but not called. TL;DR, use:

command = lambda: self.timer()

Secondly, the logic is flawed because you are setting the time to self.b each time the function is ran, instead pass in an argument:

self.b0 = Button(self.alarm,....,command=lambda: self.timer(self.e0.get()))

def timer(self, time):
    time = float(time)
    self.l2.configure(text=time)

    if time > 0:
        time -= 1
        self.alarm.after(1000, self.timer, time)
    else:
        self.l2.configure(text=time)
        messagebox.showwarning('Alarm Clock', 'Time\'s up!')

Android with Kotlin recyclerView with checkboxes randomly checked after delete list item

apologies for my limited knowledge of programming and any sloppiness. I have a reyclerview with alarm objects that I can add and it creates them. When I add say 4 alarms, and delete three of them. The last alarms checkbox is checked by itself.

The answer is quite simple, RecyclerView items are reused, so be sure that you set the all the values onBindViewHolder, because after your item is deleted, the actual view is not, so previously set values might be preset although they are not correct according to your data.

The easiest way would be to have isChecked Boolean value store in the Alarm object, onBindViewHolder always set the isChecked param on the Checkbox according to the value returned from the Alarm and when you change the isChecked inside the Checkbox listener - make sure you also update the value inside the Alarm object.

Another solution would be calling notifyDatasetChanged() on the RecyclerView, but it's definitely not the best solution especially if you have dynamic row deletion (and possibly a neat animation).

P.S. consider using viewBinding in your project, it will save you time writing all that ugly findViewById code :)))

I found the answer. I formatted the Dockerfile like this and it didn't show any errors. Also I have removed the JOptionMessageDialog parts and changed it into Scanner instead. It seems like it doesn't support GUI features:

FROM openjdk:9

COPY . /usr/src/myjava

WORKDIR /usr/src/myjava

RUN javac Program.java AlarmClock.java Clock.java

CMD ["java", "Program", "AlarmClock", "Clock"]

                                calendar.set(0,0,0,A1Stunde,A1Minute);

                                Alarm1.setText(DateFormat.format("hh:mm aa",calendar));

                            } 
                        },24,0,true

 //this part is to update the timepicker

timePickerDialog.updateTime(A1Stunde,A1Minute);
                timePickerDialog.show();

//comparison between currentTime and TimePickerDialog

Timer t = new Timer();

You can convert the current time and your TimePickerDialog into UNIX timestamp first and then compare them.
