Count Down Or Count Up With TimeLeft
What are you looking forward to? See the seconds tick down to your vacation, wedding, or retirement. Share your countdown by copying the web address (URL). The countdown automatically adjusts for DST changes in the selected location.
Count down or count up with TimeLeft
How do I achieve that? Also, for the List of dates, is there a way to make sure the countdown is to every Thurs - Sun (6pm), instead of hard-coding the dates as seen. There's no package used. I'm stuck at the code below.
The amp-date-countdown provides countdown time data that you can render in your AMP page. By providing specific attributes in the amp-date-countdown tag, the amp-date-countdown extension returns a list of time parameters, which you can pass to an amp-mustache template for rendering. Refer to the list below for each returned time parameter.
The experimental 1.0 version of amp-date-countdown uses the attribute name count-up instead of data-count-up as in 0.1 to support the "count up" feature. See the count-up section under Attributes below for more details.
Allows the amp-date-countdown component to calculate the time difference basedon the specified biggest-unit value. For example, assume there are 50 days 10 hours left, if the biggest-unit is set to hours, the result displays1210 hours left.
Include this attribute to reverse the direction of the countdown to count up instead. This is useful to display the time elapsed since a target date in the past. To continue the countdown when the target date is in the past, be sure to include the when-ended attribute with the continue value. If the target date is in the future, amp-date-countdown will display a decrementing (toward 0) negative value.
class Example extends React.Component constructor() super(); this.state = time: , seconds: 5 ; this.timer = 0; this.startTimer = this.startTimer.bind(this); this.countDown = this.countDown.bind(this); secondsToTime(secs) let hours = Math.floor(secs / (60 * 60)); let divisor_for_minutes = secs % (60 * 60); let minutes = Math.floor(divisor_for_minutes / 60); let divisor_for_seconds = divisor_for_minutes % 60; let seconds = Math.ceil(divisor_for_seconds); let obj = "h": hours, "m": minutes, "s": seconds ; return obj; componentDidMount() let timeLeftVar = this.secondsToTime(this.state.seconds); this.setState( time: timeLeftVar ); startTimer() if (this.timer == 0 && this.state.seconds > 0) this.timer = setInterval(this.countDown, 1000); countDown() // Remove one second, set state so a re-render happens. let seconds = this.state.seconds - 1; this.setState( time: this.secondsToTime(seconds), seconds: seconds, ); // Check if we're at zero. if (seconds == 0) clearInterval(this.timer); render() return( Start m: this.state.time.m s: this.state.time.s ); ReactDOM.render(, document.getElementById('View'));
class Example extends React.Component constructor() super(); this.state = time: hours: 0, minutes: 0, seconds: 0, milliseconds: 0, , duration: 2 * 60 * 1000, timer: null ; this.startTimer = this.start.bind(this); msToTime(duration) let milliseconds = parseInt((duration % 1000)); let seconds = Math.floor((duration / 1000) % 60); let minutes = Math.floor((duration / (1000 * 60)) % 60); let hours = Math.floor((duration / (1000 * 60 * 60)) % 24); hours = hours.toString().padStart(2, '0'); minutes = minutes.toString().padStart(2, '0'); seconds = seconds.toString().padStart(2, '0'); milliseconds = milliseconds.toString().padStart(3, '0'); return hours, minutes, seconds, milliseconds ; componentDidMount() start() if (!this.state.timer) this.state.startTime = Date.now(); this.timer = window.setInterval(() => this.run(), 10); run() const diff = Date.now() - this.state.startTime; // If you want to count up // this.setState(() => ( // time: this.msToTime(diff) // )); // count down let remaining = this.state.duration - diff; if (remaining ( time: this.msToTime(remaining) )); if (remaining === 0) window.clearTimeout(this.timer); this.timer = null; render() return ( Start this.state.time.hours : this.state.time.minutes : this.state.time.seconds . this.state.time.milliseconds : ); ReactDOM.render( , document.getElementById('View'));
The one downside with setInterval is that it can slow down the main thread. You can do a countdown timer using requestAnimationFrame instead to prevent this. For example, this is my generic countdown timer component:
I have noticed my says ON the entire time now (it never used to do this). It used to take roughly 20 minutes to come to pressure and then begin counting down. I started just timing the 20 minutes and then just adding whatever my cook time would be. The food always turned out cooked. Recently I started cancelling the cook and releasing the pressure as soon as the pin pops up. I take the lid off and start it again, and magically it comes to pressure in approx 2 minutes and then starts the count down. annoying that I have to keep doing this, but oh well lol
My instapot never counts down. I cooked ribs in it and set the timer for 25 minutes, high pressure. It says ON and it pressurizes because the pin comes up, and I can smell the food cooking. It said ON for an hour, until I cancelled it. The ribs were cooked. So, I guess mine is broken?
For example, to pressure cook for 10 minutes, select Pressure Cook and set the pressure cooking time to 00:10. (On some models, you may need to press Start.) The Instant Pot will say On, and once the float valve comes up it will eventually begin counting down from 00:10 to 00:00.
Hey John, followed your tutorial and got a working timer settled but I have a question. I have an audio que play every second after counting down 10 and because it is using update, it frequently plays the audio for every frame, is there a way to set the audio apart from the update but still reads from the text display? Thank you for the tutorial.
We also need to take appropriate action when the countdown is over. The following code clears the values of days, hours, minutes, and seconds and displays a heading when the timer is up. It also stops executing myfunc using the clearInterval method.
Soccer games have a clock that is constantly ticking, called the game clock. The game clock is the official device for keeping time in a soccer match. It is operated by the head referee and is often displayed in the stadium and on television broadcasts. In a standard soccer match, the game clock will start at zero and count up, stopping at halftime once 45 minutes are on the clock and resuming at the start of the second half. The clock continues to run throughout the second half until it reaches 90 minutes. Additional stoppage time is normally added at the end of each half. Stoppage time is added to the game clock to make up for time wasted during the half due to injuries, excessively long penalties, and substitutions.
The game clock counts up instead of down because it allows extra time to be added at the end to account for stoppages in play. This enables soccer to be supervised by the head referee, who keeps track of time while making calls on the field. It is easier for a referee to keep track of the time in a game if the clock counts up without pausing every time an event happens.
At the end of each half, the referees can determine added stoppage time at their discretion. If the clock counted down instead of up, extra time in the second half would cause the clock to go into negative numbers.
In soccer, the clock starts at zero and counts upward without stopping until the half is over. The clock stops at 45 minutes for a halftime break. After halftime, the clock counts upward continuously again until it reaches 90 minutes. At the end of each half, stoppage time is added for pauses in gameplay caused by injuries, substitution, and other delays.
At a party, teenager Courtney is convinced by her friends to download Countdown, an app that seemingly predicts how long a user has left to live. Courtney is startled to see it says she only has 3 hours left to live. After avoiding getting into a car with her drunk boyfriend Evan, Courtney receives a notification stating she has broken the "user agreement". Returning home, she is attacked by an unseen entity and killed as her timer reaches zero. At the same time, Evan crashes his car and a tree branch impales the seat where Courtney would have been sitting.
When Quinn finds out that Evan has died, she checks his phone, which indicates no time left in the app. Concerned that she will die in the next day, Quinn declines to go out with her family. The app informs her that she has violated the user agreement. Shortly afterward, her boss Dr. Sullivan sexually harasses her and thwarts her attempt to report his offense to her supervisor. When Quinn researches the app, she finds that similar deaths have supposedly occurred involving other users, but the public generally considers them to be fake. She attempts to buy a new phone, but finds that Countdown has downloaded itself onto it.
After being attacked by a demonic figure, Quinn meets a young man named Matt, whose Countdown states he will die in 18 hours. They learn that the user agreement is broken if the user tries changing their fate: Quinn's trip with her family and Matt taking a train ride, which they both canceled, should have resulted in their original deaths. At work, Quinn learns Sullivan has tricked the staff into thinking she sexually harassed him, resulting in her suspension. She and Matt consult a priest named Father John, who informs them that the app is linked to a demon named Ozhin who was originally summoned by a Roma woman who told a prince when he would die. Cell phone salesman Derek hacks into the app code and identifies that Quinn's younger sister, Jordan, was meant to die shortly before Quinn, then adds several decades to Quinn, Jordan's, and Matt's lives. However, while Matt and Quinn spend the night together, the entity takes the form of Matt and attacks Quinn. To their shock, their countdowns, including Jordan's, reset to their original lifespans.
