I forgot to mention I do have a 21 hour course on vanilla JS on Udemy if anyone is interested here is a $10 code.
www.udemy.com/modern-javascript-from-the-beginning/?couponCode=CZcams10
bought it and have been working through it slowly. excellent course, full of easy to follow content.
Are you will make react course i mean react front to back like angular not the course that you explain projects, please we need essential course with projects.
Working through it now - great course Brad! Anyone who wants to _really_ know javascript should take Brad's course ;-)
Definitly a great course I just got past the ajax part and it's great I can finally do some kool apps with my laravel backends, I do have one request for once if you can get a chance to do a tailwind css course that would be great Thanks Brad
Got it and can't wait to go through it.
i was looking for drag n drop! thanks Brad! God bless you and your family
Thank you brother
Traversy Media you deserve it bro!
Hi. Thanks for an amazing tutorial as always! I would do two improvements to this code:
1. requestAnimationFrame() instead of setTimeout()
2. classList.add() & classList.remove() instead of manipulating className string
Thanks again! Keep on doing amazing work!
classList.toggle is pretty neat too
I just used requestAnimationFrame and it works great thank you.
About rAF that function works on similar principles like setTimeout, but there is one thing which change everything. setTimeout based on queues executed codes (rude but it is), every setTimeout in running code is set at the end of such queue, and when queue will come to the next setTimeout, that setTimeout will be execute. rAF practically is same, but it will be invoked also like setTimeout but with one optimization thing, it's synchronization with HZ of your display. So rAF may be called faster than setTimeout or against slower, it all depends on your monitor mostly.
You should see lecture about Event Loop or Jake Archibald: In The Loop.
These new videos can be overwhelming, I am trying to stick to learning just a few web development languages that fit within my schedule but EVERY pop UP notification from Brad, are irresistible.. There is a new thing to learn or a word for motivation to upcoming developers..Thanks Brad, You the best.
I realize that. What I always suggest is having a core set of technologies that you REALLY dig into and learn through various resources BUT it does not hurt to watch and learn other things just to grasp the coding concepts, etc. A lot of time it will help you in just general logic and understanding in programming in general.
Traversy Media Thanks a bunch, you always a source of my Motivation..
Great point Sam C
I gotta say, as far as content, this is one of the best tuts I've watched. You described the topic of the video (drap & drop & their listeners) on a basic level without going into every single other feature you were using (callbacks, timeouts, etc.). A simple thing, but my biggest complaints on other tutorial channels. I came here to learn drag and drop, and I did. Thank you, subbed.
Bruh, I love your teaching style, and how you are so clear and how you show how things work instead of just watching you code. Purchased a bunch of your courses to support and subscribed (yes aiming for a cookie here) but love your lessons and thanks!
Love this channel....I have learnt Laravel, Vue.js, Building REST Service and what not....Best of the best.....
Arpan Mukherjee Go Lavavel and vuejs!
domElement.classList.toggle('hovered'); Way easier to understand and the support is there (for IE), as long as you use just one parameter (the class name string). There are also .add(), .remove(), .contains() and .replace() methods for dealing with CSS classes. Nice video!
Whenever I think of implementing something in project, on the very next day sir Brad have Video on that. Really amazing. Thank you very much for your great efforts.
Thank you for such a complete tutorial for basics and beginners on this. I love how you took the time to show us the consolw events firing off .. really made it so much more understandable!
I wish more people taught like you do. You not only make sure I understand, but you explain things in a way that I can't misunderstand. I love it!
These console messages were really useful. It helped me a lot to understand when what is run.
Your videos don't get more helpful than this. Thank you so much for not only teaching us this but do it in a way that ANYONE can understand. Truly appreciate you, man!
Love your work sir 😠. Now I am 14year old and learned js and done few projects just because of you .You gave me love for coding thanks sir .😊
That is awesome. I wish I got started that young. Keep that up and you'll run circles around other devs when you're older
you swapped your age numbers ... it's 21
Male Man what to say ..haters come every where .You do your work I will do mine.Thanks 😊😊😊😊
Traversy Media thanks for this advice sir 😊 love for code😋
The one and only Brad, who can explain JS so well anyone can understand. Thank you very much :)
Basics of Kanban board 😅 Amazing work Brad! I am really glad there are developers like you who exist to contribute genuinely to teach people! Great tutorial 😊ðŸ‘
14:08 You can mark the lines you want to copy and then shift+alt+arrow key to instantly copy&paste.
Nice Guide on Drag & Drop! You helped me implenting this on my Dungeon & Dragons Browser Game :)
Thanks, yeah I learned that a bit after this video :)
man, javascript has advanced over the years. It's really intuitive and easy to do all these complex things now. Hooray for progress! And thanks for your tutorial btw, making it look effortless is not easy, you're doing it good man.
Thanks for the free drag and drop tutorial. Whenever I need something related to programming language , first thing comes to my mind is this channel(traversy media). Your channel is in top of my list. I appreciate your work..
This video is very helpful. I just want to mention that I used a different solution to see only 1 picture while being dragged, under the cursor and not on the original place. I simply added to the . hold in the CSS an opacity: 0% attribute. This way while the picture is being dragged, the original picture in the original place becomes invisible. This might not be the most elegant solution but you do not have to use setTimeout().
Anyway, you just shortened my home assignment a lot so thank you! :)
Brad is a Javascript Rockstar in the youtube earth
Issue on Firefox: it requires the `dataTransfer.setData` function in the dragStart event. Something like this:
function dragStart(e) {
this.className += ' hold';
e.dataTransfer.setData('text', '');
setTimeout(() => (this.className = 'invisible'), 0);
}
thanks !
I work on Firefox too and knew was going to run into same thing
People like you are absolutely awesome @Vitaly thankg you
Short video and straight to the point. Excellent!
Thank you for doing these sorts of videos. It makes it easy for me to learn at my own speed.
This was also not nearly as complex as I thought it would be. I have a new understanding for how to structure such things in vanilla.
As someone who hasn't started learning frameworks yet, this helps me a lot, will implement it in my js game, thanks brad.
You know I was on the train home yesterday dead tired and I went on CZcams to watch some chill videos and I saw that one and I got sooo excited that even after a whole day of work I had to watch this :D thanks Brad :)))
thanks brad, I've studied javascript in your channel for a while and recently at my first task end up in here again! hahaha. thanks for the knowledge, happy new year.
The way Brad delivers content is next level. After having watched his videos for some time, I became a picky learner.
Didn't you create a great course "modern js ..." if it was you, you are super teacher!
i love the way you try to make us understand whats going on really :)
You struggle searching how to do something with your app... Brads got you.
Thanks man!!!
your tutorial style is excellent. thank you so much man. clear and easy to follow
Sir, your tutorials are so awesome..
Thanks :)
You never fail to amaze Brad, splendid tutorial, god bless you and your family, keep up the hard work ðŸ‘.
im doing my first js applicationa and you have some great content. not the first time this week im ending up with a video of yours. Cheers!
Worth mentioning that it's usually faster to grab an element with specific class by using .getElementsByClassName() instead of .querySelector().
This is a great tutorial. I would traditionally implement this with a library but now I am definitely going to be doing pure Vanilla for these. Thanks Brad
I don't know if anyone else ran into this, but if you click on the background on accident instead of the image and drag, you are actually highlighting the div or divs.
If you then grab the image while more than one div is highlighted, you will make the image disappear. Upon searching for the div in the inspector, you will find that it's invisible.
To fix this, add "user-select: none;" to the "empty" class in your css and it will prevent this from happening!
this is the best video i have ever seen, i mean, the way you explain it is really amazing; sorry about my english.
Many thanks brad this is what I was trying to do this week
nice, might change this into a drag and drop game
Terrific tutorial as usual. The only one comment I felt was missing was the fact that the .append() method removes the element from its prior container automatically (which is clear as you watch the elements in the Developer Tool window), but I remember wondering why there wasn't a remove() method to detach an element from the original container.
Brad I cannot tell you how much I appreciate your videos. Please keep making this amazing content. Love your channel and love your Udemy courses.
2 questions:
1. How did it work with setTimeout()
2. Why is it good to use const empty in the for loop?
Excellent tutorial without unnecessary and complicated details.
You may even use the "add(string[])" and "remove(string[])" methods of the property "classList" of an HTML element to add or remove CSS classes from it. The code will be a little more readable at first glance doing so.
Please Brad can you do more this kind of short and very useful courses !ðŸ™
And Thanks a lot! We love you💕
Man come on!!! you make everything look extremely easy, you are the one, God bless you
Awesome tutorials for drag events in front-end design! Thank you Brad!
Thank you, sir.
because of you, I was able to learn HTML, CSS, js and bootstrap in my summer vacations.
god bless you and your family.
I've been looking for this for the past few days
I'll be using this for my final project at my internship. Thank you!
Wish I could've had this video some months back when I had to do this at my first job... In the end had to settle using jQuery. Really nice video, thank you!
Great tutorial, as always, Brad. Could you do a part 2 where all the divs are filled but if you pick up an image from one div, and drop it on another filled div, the image from the first div replaces that from the second div. On drop, the image from the second div, would move to the now empty first div. I hope this make sense.
Your pronounciation and expression is very clear, I can easily understand you. Thanks bro
Oh Brad you do make my day, thank you so much for all your hard work!
Love you Brad. You're a nice guy!
You are the best Brad! Thank you very much. Every time I watch your videos, I learn something new, simple and (that is important) very interesting
Really Huge THANKS!!! You made something, what is really useful with this video! Thank You so much again!
I followed this tutorial and took it forward by adding swap, add and delete functionality along with drag and drop. Have a look if you are interested
czcams.com/video/AAmx-WWKCKM/video.html
I saw this on my CZcams dash and said "Yeeeeeees". Love the tutorials, Brad!
Select code and press Alt + Shift + Arrow Down. :) Would like to see the same stuff but with some table rows. Like re-ordering tasks by their number of priority (with actually changing number of priority/or order).
Thank you very much for sharing, exact video I was looking for.
Just buy your Vanilla JavaScript course, I hope I will learn lots of new things from that udemy course. Thank you, Brad.
Excellent video Brad, just what I was after! Could you explain the invisible and doubling box again where you used setTimeout? I couldnt see any visual difference?
Im a python guy but with your videos i have learnt a lot thanks for the time youbput on this man
Hey Brad! I can't thank you enough for sharing your knowledge & helping others achieve their goals.. thank you so much. I wanna be one of your Patron in a near future!!
Great video! Figured since this is JavaScript, I’d throw out a suggestion for a future video. I’m interested in a video showing the use of lazy loading images on a site with many of them, so that images below and even above of the viewport are temporarily removed to reduce browser strain
Interesting and helpful, It works in Chrome, almost works in Edge and in Firefox the image disappears as soon as I begin to drag on it. Javascript is enabled in Firefox but Edge I can't find the supposed place to check it.
Firefox does support HTML5 draggable. But it does not automatically figure out what´s the data to be moved. As chrome does. If you don´t tell it anything.
You have to add
let img = new Image();
img.src = "source.unsplash.com/random/150x150";
e.dataTransfer.setData("image", img);
into dragStart(e)
@@shioli3927 I was struggling with this, thanks for sharing this information!
I love this channel
Another high quality video!!! I learned so much updated JS from you, thank u, sir^_^
very good video and explanation, i found what i searched for
Great video. It's incredible how you keep doing videos explaining things I would need to look up in near future.
Seeing this in es5 would be cool.
Hard to tell what I have to do to use this in production.
Have re written most of it in es5 but,
12:00 *this* keyword binds to something different in es5 vs es6
Great job explaining everything, very much appreciated!
Really, really great video and in-depth explanation. Thanks for sharing Brad!
to be honest amazing tuts, i was looking for something like it..., and the console.log explanation was top notch.
Awesome tutorial :). I was thinking of doing it yesterday and you made it easier! Thanks:)
Very instructive and useful. Thanks!
Fantastic, this is what I was looking for
@travery media - thanks for that. super fun lunch project
Exactly what I was looking for. Thanks, Brad, for save me one more time!
Appreciate the explanation of what is going on - good stuff!
You are awesome Brad, and i really missed your facecam, hope you are now all set up with your new office,expecting a new setup tour soon:)
Ash Klmepton Seems like he had to drag and drop so much stuff in real life that the idea of this tut was born 😂
Best programming channel🙌
Amazing explanation and very simple and direct! Thank you!
great tutorial. it worked on Google chrome, opera browser and Internet explorer 11. it didn't work on Firefox quantum. it just didn't work. please try it and tell me how to fix it. Another thing is, i got warnings from Vs Code that const can only be used in ES6...
Thank you, man. A very good introduction to drag&drop event.
I can not thank you enough man. You are saving my day almost everyday!
Thank you. People might not be familiar with 'this' method during beginner stages, so could've been better if this was accomplished without 'this'. The video was good. You're good at explaining things. Keep it up.
Nice video very clear and simple and strait to the point, keep up the good work
Hey Brad... Another great tutorial, thank! Only thing I noticed that this doesn't work on a touchscreen or mobile... I tried to look for solutions but I just found lots of questions and no good answers so far... Do you know how to do this?
have u found out yet
*Awesome!* I was struggling to do good drag&drop on es5 but it's so much easier on es6
You are the best man, simply the best. Your tutorials have so much helped me especially for Vanilla js. Thanks and
God bless You
Brad Traversy !! I love you brother from the bottom of my heart, you really changed my life :)
If you're struggling to drag multiple images on multiple div boxes, it's better to use dataTransfer. Here is how it can be done:
Assuming you have multiple images, you can use for(img of images){//dragStart event & dragEnd event}.
You can then go on to write the event functions
function dragStart(e){
e.preventDefault();
//set the id of the target image
e.dataTransfer.setData('text', e.target.id);
}
function dragDrop(){
//Your codes
}
In your dragDrop function for the empty boxes, you can write
function dragDrop(e){
e.preventDefault();
//get the id of the dragged image
id = e.dataTransfer.getData('text');
//append the dragged image
this.append(document.getElementById(id));
}
It took me sometime to figure this out until I learned about how to use dataTransfer.
Hope this is helpful.
Your tutorials are awesome!
This is awesome. If I wanted to add another picture, would I, for example just repeat this process?
very simple and neat
Hi, could you explain to me why in that particular instance a for loop doesn't work?
Amazing work once again.
