Trust me this is the best tutorial channel I ever seen
Best tutorial everr...
thank you so much. may Allah bless you . very useful tutorial.
No worries mate!
Yes found it, sorry mistyping.All work now thank you Dom.
how did you fix it may I ask? I'm having the same issue, It say's it's something to do query selector being null or something and I cannot find the issue.
Just a question, why reader.readAsDataURL(file) needs to be after reader.eventlistener( ) function ???
Thank you so much bro❤️ I just did it in my project 👍👍Thanks a lot
8:14 - Don't use arrow functions, they inherit their "this" from the parent scope
Bro, this helped me a lot, but a friend came with the following solution: img.src = URL.createObjectURL(file). Works like a charm!
awesome tutorial sir
Very good video, you earned one more subscriber!
Thank you soooo muchhh!☺. I just subscribed.
how do i solve the error it shows in the log "previewContainer is undefined"
You just earned one more subscriber!
Nice trick with these null values, didn't know about that. Thanks a lot!
Why not use createObjectURL(file) which will create a blob reference to the file in memory vs creating a base64 string ? which one is more performance. createobjecturl is easier one line no callback needed.
you know i was struggiling to find to preview image when i found you it became
easy
u are the best dude, thank u
what about previewing multiple images? what changes should i do while implementing ur code?
Thank you Brother ! just amazing as the rest of your tutorials
It's great tutorial! I would like you make tutorial about showing preview image with remove button and upload multiple files.

Pure Content . Respect 💛💛
Very good tutorial, I just have a question, do you know how to do that but having 2 input files in the same form without repeating the function 2 times?
Unfortunately for some reason keep giving me error.excel.js:38 Uncaught TypeError: Cannot read properties of null (reading 'style')
at HTMLInputElement. (excel.js:38:24)
previewDefaultText.style.display = "none";
I am doing something wrong but don't know what.Source code would be helpful.

How would one save the image after it was uploaded, ie if we changed the image size?

Nice tutorial sir, but can you help on how to preview multiple selected images before upload? Like airbnb have on their website
awesome! Thank you!
Great Tutorial
Would love to see an image previewer tutorial that handles multiple files. I can find anything anywhere
hey! too late, but you can try making the containers that you need with the same classnames an id's, and in JS just querySelectorAll, like this (more or less):
inpFile.addEventListener('change',function (){
for(let i = 0; i < this.files.length; i++){
const file = this.files[i]
if(file){
const reader = new FileReader()
previewDefaultText[i].style.display = "none"
previewImage[i].style.display = "block"
previewImage[i].style.objectFit = "cover"
reader.addEventListener('load', function(){
console.log(this)
previewImage[i].setAttribute("src", this.result)
})
reader.readAsDataURL(file)
}
}
})
hope help you ! (sorry for my english)
you are the best
Great tutorial, wish you more success.

Thanks, it helped.
Algún día programare así como tu amigo!
Thanks for this will surely watch this tutorial. Do you have any idea on how to make a link previewer?
Ultimately, I think you have to use/create a webscraper. Alternatively, you can use a link previewer API that already have this functionality implemented. I use Facebooks Link Preview API.
Awesome tutorial!
Cheers!!

Hello, How should I modify the code to Preview ".pdf" file before file Upload?
Anyone know how to make it so that the preview image that's larger than the container doesn't overflow it?
I've tried messing around with the height of it in the css but it always squashes the image rather than sizing it down proportionally.
try object-fit: cover
can we use for PFD uploder as well ?
thank u sir....
No worries mate
i can't get .style in my js code help

I get this message "Uncaught TypeError: Cannot read property 'addEventListener' of null". How to solve it
It means you're trying to select an element that doesn't exist (or doesn't YET exist). As a potential solution, try using the DOMContentLoaded event or put the SCRIPT tag at the end of your BODY tag.
