Timer history

Surprisingly, the first timer appeared in Ancient China more than 2.5 thousand years ago. It was a stick made of resin and sawdust, which was set on fire at one end; at the other end there was a weight - when the fastening thread burned out, it fell with a ringing sound. At the same time, Plato in Greece invented an analogue for inviting students to lessons; Leonardo da Vinci also worked on similar developments.

First mechanical timer appeared in the mid-1800s, it was the traditional alarm clock used today that set its hands to the desired time. By the end of the 20th century, an electronic timer appeared - the most accurate device now used in smartphones.

Step-by-step instructions: how to use the timer?

It happens that you need something countdown timer, there are many solutions on the Internet, but they are either very cumbersome or have dependencies on other libraries. Today we will look at how to make a countdown timer in javascript in 18 lines of code.

Plan

• Calculate the remaining time

Set the correct end date

Firstly, you need to install correct date graduation. This will be a string in any of the formats that it understands Date.parse() method. Eg:

Var deadline = "2015-12-31";

Short format

Var deadline = "31/12/2015";

Or long format

Var deadline = "December 31 2015";

Each of these formats allows you to set the exact time (in hours, minutes, seconds) and time zone. For example:

Var deadline = "December 31 2015 23:59:59 GMT+02:00";

Calculate the remaining time

Function getTimeRemaining(endtime)(
var t = Date.parse(endtime) - Date.parse(new Date());
var seconds = Math.floor((t/1000) % 60);
var minutes = Math.floor((t/1000/60) % 60);
var hours = Math.floor((t/(1000*60*60)) % 24);
var days = Math.floor(t/(1000*60*60*24));
return (
"total": t,
"days": days,
"hours": hours,
"minutes": minutes,
"seconds": seconds
};
}

First we create a variable t to store the remaining time. Date.parse() the method is built in javascript and allows you to convert a string with time into a value in milliseconds. This will allow us to subtract one time from another and get the difference between them.

Var t = Date.parse(endtime) - Date.parse(new Date());

Convert the date to a convenient format

Now we want to convert milliseconds to days, hours, minutes and seconds. Let's use seconds as an example:

Var seconds = Math.floor((t/1000) % 60);

Let's figure out what's going on here.

• Divide milliseconds by 1000 to convert them to seconds
• Divide the total number of seconds by 60 and keep the remainder - you don't need all the seconds, just the ones left after the minutes have been counted
• Round down to the nearest whole number because you need full seconds, not fractions of them

Repeat this logic to convert milliseconds to minutes, hours, and days.

Output timer data as a reusable object

Once the hours, minutes and seconds are ready, we need to return them as a reusable object.

Return (
"total": t,
"days": days,
"hours": hours,
"minutes": minutes,
"seconds": seconds
};

This object allows you to call your function and get any of the calculated values. Here's an example of how you can get the remaining minutes:

GetTimeRemaining(deadline).minutes

Convenient, right?

Display a clock on the page and stop it when it reaches zero

Now we have a function that returns us the remaining days, hours, minutes and seconds. We can build our timer. First, create the following html structure for clock:

Then write a function that will display the data inside our div"a:

Function initializeClock(id, endtime)(
var clock = document.getElementById(id);
var timeinterval = setInterval(function())(


" +
"hours: "+ t.hours + "
" +
"minutes: " + t.minutes + "
" +
"seconds: " + t.seconds;

}
},1000);
}

This function takes two parameters: id element that will contain our clock, and the end time of the counter. Inside the function we will declare a variable clock and we'll use it to store a link to our clock block, so we don't have to ask DOM.

• Calculate remaining time
• Display the remaining time in our div
• If remaining time = 0, stop clock

The only thing left is to start the clock like this:

InitializeClock("clockdiv", deadline);

Congratulations! Now you have simple countdown timer in just 18 lines of javascript code.

Prepare your watch for display

Before styling we will need to refine a few things a bit.

• Remove the initial delay so that the timer appears immediately
• Make the clock script more efficient so that you don't have to constantly rebuild all the clocks
• Add zeros as desired

Removing the initial delay

In watches we use setInterval to refresh the display every second. Most often this is normal, except at the beginning, where there is a 1s delay. To fix this we need to update the clock once before setInterval starts.

To do this, let's move the anonymous function we pass to setInterval(the one that updates the clock every second) into its own separate function, which we'll call updateClock. Call this function once outside setInterval and then call her again inside setInterval. This way the clock will be shown without delay.

In your javascript replace this:

Var timeinterval = setInterval(function())( ... ),1000);

Function updateClock())(
var t = getTimeRemaining(endtime);
clock.innerHTML = "days: " + t.days + "
" +
"hours: "+ t.hours + "
" +
"minutes: " + t.minutes + "
" +
"seconds: " + t.seconds;
if(t.total clearInterval(timeinterval);
}
}

UpdateClock(); // run the function once to avoid delay
var timeinterval = setInterval(updateClock,1000);

Making the script more efficient

To make the script more efficient, we need to update not all the clocks, but only the numbers. To do this, put each number in a tag span and we will update only this content.

Here html:

Var daysSpan = clock.querySelector(".days");
var hoursSpan = clock.querySelector(".hours");
var minutesSpan = clock.querySelector(".minutes");
var secondsSpan = clock.querySelector(".seconds");

Function updateClock())(
var t = getTimeRemaining(endtime);

DaysSpan.innerHTML = t.days;
hoursSpan.innerHTML = t.hours;
minutesSpan.innerHTML = t.minutes;
secondsSpan.innerHTML = t.seconds;

...
}

Adding leading zeros

If you need leading zeros, you can replace code like this:

SecondsSpan.innerHTML = t.seconds;

Like this:

SecondsSpan.innerHTML = ("0" + t.seconds).slice(-2);

Conclusion

We have considered how to make a simple countdown timer in javascript. All that's left for you to do is add styles. Thank you for your attention!

Hello dear friends. In one of the previous articles, I discussed whether it is worth using (also called a countdown timer) on your landing page. So, if you think that you need it, then today I will tell you how to connect it to your landing page.

We will talk about several options, in one case it will be a countdown counter script that will loop every 24 hours. That is, you will be able to make a promotion. For example: “until the end of the day -” and the timer will show how much time is left until the end of the day. After a day, the timer will restart and start counting again

And in another version, I’ll tell you about online service, which allows you to connect a countdown counter. But here it is assumed that the meter is designed for a long period of time. For example, you plan to open a website in a month, and for now you have made a stub of the form:

It can be used in different ways, for example, if the promotion is one-time and designed for a long period of time, then online connection more profitable, since you only need to add one line of code in the right place. In general, depending on the purpose, choose the appropriate option for you. Let's get started...

Countdown counter with restart

So, a countdown counter that will restart after a day. It was developed by a craftsman who has a blog mywpnote.ru. I came across the blog about six months ago, and it really helped me out at that time. Today I want to tell you about one of the meters that he developed and describe how to connect it.

The timers look like this:

Download the sources and in the archive you will see 4 folders with the names vid1, vid2, vid3, vid4 - in them different types design of timers. You can see everything and choose the one you like. The connection method is the same for everyone.

I will show on 4, since it seems to me to be the most universal. We open vid4 and we see a standard set of folders for most sources on the network. (index file, folder with style sheets, folder with pictures, and folder with the script). I slightly changed the file structure to make it easier for beginners to connect the meter. That is, I moved the timer script into a separate file, but before it was in the index file.

How to connect a countdown counter script to your landing page?

Open index.html with any editor (I use sublime3) and see the following code.

From here you need to copy the connection of the style sheet and script (line 7 and 8) into your project.

And also, in the place where you would like to place the timer, you need to add a div tag with the “countbox” class – line 13. The code specifically places multiple timer connections to make it clear that they can be used multiple times on a page. Many scripts have problems with this, and the second time they do not want to be displayed on the screen.

Now you just need to copy the img, css and js folders, as well as their contents, into your project - and that's it! The countdown counter will work! As you can see, it takes a maximum of 5 minutes, and such an important element will be present on your site. If you have any questions, write in the comments, I will definitely help you connect the meter!

Countdown counter online

For those who need a different type of countdown counter, which was mentioned at the beginning of the article, there is a service with an incredibly simple connection method. All you need to do is go to the website www.timegenerator.ru and select one of the proposed timers.
