Build A Clock With JavaScript

Black Sabbath - Iron Man. Just the song alone would have been enough for the like and sub, but the class too was very good and greatly helpful. Great Job!

[@zawadahmed5484]

honestly speaking, among all the javascript devs, Kyle is the most talented. That's my opinion

[@TheWorldlife83]

Thanks for this, all your videos are very useful, short and precise. 🙂 we can add this JavaScript to rotate numbers without writing 12 different css - let allNum = document.querySelectorAll('.number'); for(let num of allNum){ num.style.transform = `rotate(${30*num.innerText}deg)`; }

[@harunjonuzi]

it doesnt seem to work though? we need to transform the innerText to number, because 30 * "1", it uses strings to multiply...

Thank you. I like using CSS when I can for designs since it is so fun to work with.

[@mandihaase2744]

Awesome simple, straight-forward tutorial. Did this with my daughter and she loved it!

[@levezinet]

Thank you so much for an incredibly great video. I have been struggling to make clocks and gauges and this provides a superb implementation of the design patterns I need. Bravo. But my clock would not move, and debugging showed null values for the hands. Toward the end of the comments here a large number of people appear to have the same issue. It seems to me that the call to document.querySelector is using search by attribute (['date-hour-hand'] etc) but these attributes do not exist in the sample HTML given for the hands. I simply added an id to the hand divs and used document.getElementById instead and all works perfectly. I thought others may like to know. It would seem that this is an inconsistency in the code in the video, and I suppose videos are hard to go back and edit corrections in. I'll be adapting this to make clocks and compasses for use in Node-RED. I owe you much gratitude. All the best from Down Under in Australia!

[@medilies]

"Absolute children indise an relative container" changed my life I used to make a JS scirpt that follows the container position to update children positions

[@andrei9115]

So basically, in your javascript program you call the current Date every time and then you just display that date accordingly. I think, a more practical way would be if you get the currentDate() once and then from second to second increment all the hands accordingly and then check the currentTime from the Internet and your clock and see if they are the same...I mean, your way is much simpler than trying to calculate how many degrees does the minute and hour move in 1 second and increment it every second :) Keep up the good work!

[@code_south]

I made a tiny improvement where the numbers are not upside down/rotated themselves, so they look straight (just wrap every number and then use the wrapper to correctly position the number around the circle, and then rotate the number inside the wrapper by compensating the angle just with a - before) and also added a tick tock sound to each movement lol.

[@jaishrikrishna5755]

how you added the sound can you please share .Thanks

@@jaishrikrishna5755 Of course buddy. //It plays 2 different audio clips depending on if it's even or not, to have more variety haha... It's an old code and haven't revised it but here it is. This goes inside the same setClock function: let factorX = currentDate.getSeconds(); if (factorX % 2 == 0) { let audio = new Audio('snds/clock1.mp3'); } else { let audio = new Audio('snds/clock2.mp3'); } audio.play();

Finally finished this project after like a week of on-and-off effort. Tips/a vid on sustaining effort perhaps? I can only concentrate on this stuff for like 2-4 hours before my mind refuses to absorb anything more.

That is a good idea. 4 hours of focused concentration pretty good if you ask me. My best advice would be to take a break when you start to lose focus and come back after 30 minutes or so. That will freshen your mind up.

[@toyosisalami6453]

Thank you very much for this great tutorial! I understand the code but I couldn't have figured out the math of it... I just don't know how to figure out how many degrees the minute and hour hands turn each second

[@andrei9115]

Because that formula that he used is not that easy! I made it by myself using just angles. Think about every second runs through 6 degrees, every minute and every hour 30 degrees(6*5). Then you just increment the angle for each of those and that's it. If you want the minute and hour hand to move gradually with every second that passes, then you will have to make a simple math calculation, is not difficult! That ratio thing that he used literally blew my mind. Css part was incredible, congrats but the javascript side was so difficult to understand!! I dont understand why my minute and hour elements translate on X very little, like 1 degree after I load the page...

To do this, I put the numbers in their own div and reversed the angle of rotation like so: 1 2 etc

to automate it just do transform: rotate(calc(var(-rotation)*-1)); that should work as im pretty sure it inherits the variable An example: HTML:
