How To Fix: "null has been blocked by CORS policy" Error in JavaScript AJAX

[@antoniofuller2331]

I hate when they say "a very simple fix" lol

[@mounir101]

Pretty awesome! I think every programmer had faced this problem before. Even I faced it as well and fixed it by using live server extension. Thanks so much bro for helping people to solve this issue.

[@chembetikarunakar814]

Without liveserver can we do this

[@NoobDeveloper_123]

thanks brother, i were suffering from a lot and seeing many tutorials from different channels. most of them created garbage tutorial and finally from your side i get the original solution.

[@cloudzero2049]

I'm over here training neural networks and getting ready to pull my hair out because CORS wouldn't let me load my trained models (ML5.js library). I let out a huge sigh of relief when you said VS Code has a server extension, I was worried I was going to have to design a Node.js overlay. Every things working, thank you so much.

[@RIGARR]

woah! what a coincidence! I was just searchin' to fix this problem and got your video just uploaded

[@pavelromanov8833]

You man are a live safer. I've been banging my head for the past 3 hours and I feel relieved to have finally solved my problem. Thank you very much sir!

[@userg23]

Excellent explanation. Simple and short.. Easy to understand. Thnx man 👍🏻

[@ScreenPrintR]

Do I have to re-save my file in VS code? When I hit enter after doing the f1 I get a message on the bottom of vs that says open workspace.

[@christianrivera1568]

This video is the response to my 2 weeks problem. Thank you sooo much!

[@Olalekan.Ekundayo]

So, I found someone like me that was stuck with this error message for weeks 😂

[@juliuspaige5173]

How do you fix it if downloading a webserver is not an option?

[@MarkKathrynVegera]

Excellent and thank you for saving me another two hours of checking my code!

[@Olalekan.Ekundayo]

Wow! You just gave me a solution to the error message I have been encountering for weeks now, and has slow down my learning... Thank you very much, you deserved a like and a subscribe from me 😄

[@my.b707]

The same, that slow my learning an I was sad. Now I can continue

[@smoothbeak]

When running that live server option in Visual Studio Code what's the keyboard shortcut for macOS to open up that panel? (he uses F1 on windows)

[@einsteinwallah2]

ok so file on hard drive with extension html or htm or any other cannot access pages from (say) a news or literature site but what if i am writing an android app using cordova platform ... once i finish writing app following your work arounds and i upload app will it work on any android which has "bought" from app store? ... remember person who "buys" just gets app ... will ajax or fetch still work because no server is running on android device of buyer afaik ... my code is not for a client's website but for a device like android ... when it is game like wordle hosted on nytimes website's games page it is still an access from server to server but when an app is running on an android device it is running exactly like a file from storage just like your error giving file ... please correct me if i am wrong

[@KinTsume]

I'm having the same error but i'm using fetch(). I tried to load the page with live server but still doesn't work. Any advise?

[@clutchmasterman]

problem is this only works for the .html alone. no other .js or .css file in the folder, which ofc breaks the project

[@Felix-vu9tz]

thanks man, helped with starting my journey learning react, I was getting pretty frustrated as I wasnt even able to print hello world but now i should be able to actually get going, thanks!

[@ankitkumar-zx9mq]

Didnt worked for me

[@HonduranHunk]

Saved me what would have been hours of scouring the internet. Thank you so much

[@Harry-gc8kb]

but then whuy do you get the error if you fetch it from your own harddrive?

[@chatebillychilima6762]

Perfectly summed up.... Easy and great fix. Thanks bruv

[@alin-alexandru-peter]

maaaaaaaaaaaaan your the best !!! I need your tutorial for the timer and i was getting this error you fixed it for me!1 great job ! you and coding train:))) are my favorite developers ever.

[@baqsinternacional975]

Hi, thank you for the video, my problem is a bit diferent, my cliente need the site to run offline in a company, and he can´t install the server in machines, because security compliance, how can i fix that? i´ve been trying this for more then 24 hours. I´ve created a bat file to open navigators without security in anonimous mode, however that´s not the ideal

[@alexthewebdesigner1856]

Thanx for posting this Bro. It was a great help!

[@DJMIKE20]

Can you show how to solve this issue with the fetch method ?

[@imaansarwar2314]

[@aviuvaydov5690]

[@JHAM29]

How do i fix "because the scheme does not have a registered handler."

[@JHAM29]

"Cookies marked with SameSite=None must also be marked with Secure to allow setting them in a cross-site context. This behavior protects user data from being sent over an insecure connection."

[@michaelwhite278]

Did you do the voice for the whale in the beached whale / chips bru video?

[@almohaiminfarabi9181]

Is there any way to do it without live server extention?

[@jossuer7124]

If I dont want to use a web server?

[@changleding4296]

[@WaheedRafiq]

[@vicerogi]

I'm used to active live server, but this time I didn't cause I thought there will be some problem with scss ( it is the first time with this preprocessor) And I was searching different solutions. I did not expect it at all jajaj my gosh, thanks indeed!!

[@davidpadron8329]

Thanks man for the explanation. This helped me to solve the problem 🙂👍

[@bhoopendrafagna8535]

[@short_facts_entertaining]

[@blazi_0]

Is live server like local host ?or they're different stuff ?

[@thenarfer]

Fantastic video! I hope this will solve my problem. Will try to upload my files to my server and see if the problem still occurs.

[@karlee8608]

Thank you dCode. You just solved it issue

[@catz6457]

What about in GeoServer

[@davestorm6718]

You need Browser Preview Extension installed as well to get this to work, however, it's been deprecated in favor of Live Preview (you have to uninstall Live Server, first).

[@soufianetaku3137]

thanks man it's really working

[@umangupadhyay4335]

[@marhlenz6476]

Thanks man, excellent explanation.

[@danielroman1484]

I opened mine with live server but the error is still there

[@aviuvaydov5690]

were you able to figure it out? I'm getting the same error.

[@comentarioscomentar]

i know that is too late but try this : you Don't make double click in the index.html archive to execute in the navigator. Instead, power on the server, open the navigator, enter in the address "localhost" and search manually the file to execute in the list.

[@AhmedMohamed-sn1rp]

Thank you so much It really helped me

[@tentorias8344]

Oh man, thank you so much, you save my life.

[@freddecker7652]

Well, something changed in our code, because it works in previous versions. We can't have people have to have a web server, that's ridiculous. Our app is designed so that anyone can download a zip file, unzip it, and run a web based tool. There must be another way.

[@ScreenPrintR]

Thank you. This was extremely helpful Kudos to you.

[@lindaoktavianty2688]

Thank youu so much.. your video is so helping 😭

[@anthonysanchez119]

te lo agradezco mucho estaba pariendo y pujando por ese error, pero gracias a ti lo he corregido. Awesome, thanks

[@sarahz319]

[@isoftenterprise]

On the money my boy!

[@sarahz319]

how did u get into 03:36

[@alfonsoramirezelorriaga1153]

Go to settings and then go to online service settings.

[@seayellow5834]

Not solved. I got this even on a server. I used an XMLHttpRequest object and I got this.
