Hi : )
I have finished the programming of my clock and it seems to work the same as the example provided by Peter Weinberg:
https://gabehaus.github.io/Pomodoro1a/
I am still failing some tests so have not styled my clock yet. The main failure seems to be:
8. I can see an element with corresponding id=“time-left”. NOTE: Paused or running, the value in this field should always be displayed in mm:ss format (i.e. 25:00).
- time-left is not formatted correctly: expected ‘59’ to equal ‘60’
I think the problem is related to this condition:
} else if (seconds == 0 && minutes != 0) {
setSeconds(59);
I’m frustrated because if you test my clock, it seems to behave the same as the clock provided by Peter Weinberg. If I change setSeconds(59) to 60, it messes up the whole program. I’m looking for a way out without having to start from scratch. This is very demoralizing.
Thanks again for your help…
Here is the code:
App.js
import React, { useState, useEffect, useRef } from "react";
import "./App.css";
function App() {
const [seconds, setSeconds] = useState(0);
// active set to true means clock is running
const [active, setActive] = useState(false);
const [sessionLength, setSessionLength] = useState(25);
const [reduceSession, setReduceSession] = useState(false);
const [increaseSession, setIncreaseSession] = useState(false);
const [breakLength, setBreakLength] = useState(5);
const [reduceBreak, setReduceBreak] = useState(false);
const [increaseBreak, setIncreaseBreak] = useState(false);
const [minutes, setMinutes] = useState(sessionLength);
// blockType can be set to "Session" or "Break" and is displayed by id="timer-label"
const [blockType, setBlockType] = useState("Session");
//ref referring to audio element
let qRef = useRef();
//initial call of setInterval
useEffect(() => {
var myVar = null;
if (active) {
myVar = setInterval(myTimer, 1000);
} else if (active == false) {
clearInterval(myVar);
}
return () => clearInterval(myVar);
});
//condition that audio plays when clock hits 00:00
useEffect(() => {
if (minutes == 0 && seconds == 0) {
qRef.current.play();
qRef.current.currentTime = 0;
}
});
//function called by setInterval - Problem here in that I set seconds to 59???
function myTimer() {
if (seconds > 0) {
setSeconds(seconds => seconds - 1);
} else if (seconds == 0 && minutes != 0) {
setSeconds(59);
setMinutes(minutes => minutes - 1);

setSeconds(0);
setBlockType("Break");
} else if (minutes == 0 && seconds == 0 && blockType == "Break") {
setMinutes(sessionLength);
setBlockType("Session");
}
}
//function called onClick of reset button
function resetting() {
setActive(false);
setSeconds(0);
setSessionLength(25);
setMinutes(25);
setBreakLength(5);
}
//conditions for dealing with the click of buttons that change session and break times
