for anybody trying to learn JavaScript. i've found most helpful is following along with Quentin, writing it out and making the mistakes. then writing it out from scratch again without the vid and actually telling yourself what it is you're doing. it became internalized that way for me because now i know the functions, variables, methods etc. and what they're doing/mean/ etc. as opposed to just blindly copying and moving onto to the next vid, which is what i originally was doing and realized i wasn't internalizing everything. ne ways, thx again Quentin! you're a great teacher with wonderful teaching skills and good luck all.

No better man for this job Quentin.. I really think there is nobody that explains it that well pal. Perfect rythm, everything very clear.. Keep it up:)

Great Tutorial... been looking for this info for months for one of my sites. Tried it and it worked like a charm. Thanks Again! Subscribed and Great Tutorial!

You are the man Quentin Whatt ,seriously!!!!, I hope your not wasting your talent teaching for free, you defiantly need to be getting paid for this.

Your tutorials are so helpful, I used them to study for my final Exam you make them so easy to understand.#ContinueTheGoodWork

Bravo!!!! your teaching way is marvelous+ comprehensible!!! Thanks a lot.

Thanks Quentin, your clips are brilliant!

Thank you for this. I can't wait for the next ones to come out.

Your videos are so good! Makes me understand things I did not understand from my course! 🙏🙏🙏

Thanks for this series. Great JumpStart!

Thanks Quentin for amazing video tutorial!

Thanks a lot! I started coding HTML/Java/CSS and this helps alot!

Thanks Quentin. Clear and precise instructions and it's all working well. Thanks a lot. May I make a small suggestion? I'm new to Javascript and needed to follow the coding exactly as you wrote it. It would have been good if you could had displayed the final and completed code in one screen shot at the end of the tutorial as I had made a typing error which I'd missed and this would avoid keep going through the tutorial over and over again. Thanks again. Alexandra.

Thanks Quentin. It's awesome video.

I owe you a big Thanks Man! God bless ya!

Thank you again! GOD bless you and keep you.

Thank you!

very helpful

Nic teaching sir thankyou

thanks for this tutorial. I learnt a lot. Do you also plan tutorials for server side scripting e.g. PHP, MySQL? I am interesting to understand how to build a web application with client, server and database. I know....many requirements :-)....good luck for the exams!

Thex Quentin...:)

Hey Quentin! I have a question. For inputs such as username and password why do we even need a name parameter? I mean how do we use it later on?

Great....👍🏾

thank you,

Nice teaching sir

it is good! do for another

hello quentein i wanna ask you that can explain if there any way get value other than get element by id

thanks a lot!

u don't need database or server-side, just make a sample variable for each input. var username = "quentin" and u can make a validation username === usernameFromInput

Hey Quentin, is it better practice to handle events in our scripts rather than HTML?

Best!!

Super!!

thank you! :)

How about if its more than one field? Do we type out all the variables inside the if else statement? Isn't their an easier way instead of typing 10+ var inside the if else statement?

How do make it so when a user types in the wrong patter (like not using the @ symbol in an email) that a message appears? I want different messages to appear based on the field with the error.

amazing wow thanks

hi what code we use to refresh login page if user enters wrong details.jquery or javascr

thanks.

in onsubmit attribute where and what it is returning ?pl clarify

what is the difference between name and id of form elements.

Not work for me... for now, I can't find what is problem I made same thing

I tried to put space in both the password and username field and unfortunately it still submitting the form

Hi Quentin Why doesn't my password input area show black dots ?? because i am running in google chrome ? ive gone over my code and compared it with yours

i am not able to perform validation on ma form i am doing excatly how you told to do so but on clicking on submit button it is still redirecting to next html page

What is the use of

how can we use normal empty message instead of alertbox?

Awesome

when you will start your php tutorials.

do you have with lockal storage?

bro how to validate whether an authenticated user has entered if not after registering how to validate using javascript?

but what if user submitted incorrect data ?

I don't get it. I get the error message with the form method "post", but it works when I change the method to "get". "post" won't direct me to submission.html, but "get" does. :( Username: Password:

how javascript add with php

Hello...... I am looking for tutorial 31 onwards.... but unfortunately i could not find in KZfaq so please can you send me the complete tutorial link?? This tutorial is really very nice!! Thanks!!!

when i click login, with blank fields, nothing happens!

I have one doubt that is how to display the user name in the action = "submission.html" page and iam searching for this for long time

interesting Easter egg, biatch arrives at 7:29 (closed caption only)

I used the same code but instead of .value I used .length to test if the document.getElementById('username') is greater than 0. However, the code didn't work as both times it returned the submission.html page even when I had set return false for .length = 0. Can anyone explain what's wrong with it. I kept everything else the same.

Shouldn't the condition be & only then its right to evaluate...Also i have a doubt..By this we check only if the string is empty right..In case we give spaces only then the data is still validated..So is there anything like trimming or something that we could add ??

i work in adobe dreamweaver...but at "else" it give me an error ..why?if u can help me... function check_info(){ var username = document.getElementById('username').value; var password = document.getElementById('password').value; if(username=="" || password=="");{ alert('please fill in all fields'); return false;} else { return true;} }

why do you have to give the forms a name and a type?

I'm about to post a webpage. It's an Italian tutorial. I want to charge people to get into advanced lessons. This webpage will have a password feature. I will send my customers passwords to access advanced lessons. How can I prevent people from selling the passwords I issue them? In other words, how can I make sure the person using the password is the person who purchased the password?

The if condition has to be && not || so that both conditions are checked..

Can you upload the code for this tutorial? For some reason, although I followed your every step more than once, it stilled sent me to the next page when I clicked "login" without writhing any password or username...

If I enter a username and password is left blank, I can still send the data. :o

Now make a tutorial on how to pronounce "data".

I have used the same code but it is redirecting to next page😒

If it doesn't work put three = in if statement. if(username==="" || password==="") { alert('Please fill in all fields'); return false; } else { return true; }

I think that this Stack Overflow post underlines the difficult point of this vid: stackoverflow.com/questions/5195933/with-form-validation-why-onsubmit-return-functionname-instead-of-onsubmit

Are you Zimbabwean?? Random question I know but I can hear a slight bit of African in there for sure!!

data sounded daughter :D

I Want To Create Excellent Codes....

Thanks for the tutorial. I want to validate form using Level2 DOM like using addEventListener('submit',function,false) andnodeValue, textContent etc. How to do this? Just have a look at the bottom of the JS section of my codepen (codepen.io/ksharifbd/pen/vEyydm). You'll have an idea. Please help me out in this regard. Quentin Watt

thank you for submitting your daughter

Damn South Africans :D

Wont work :|

i too hear daughter lol

1:46 - thank you for submitting your daughter. creepy.

Thanks for this great tutorial, I changed the subject with same way to do it ,but it's not work, Can someone help?? Age Gender function requireInfo(){ var condition = document.getElementById("condition"); var age = document.getElementById('age').value; var gender = document.getElementById('gender').value; if ( age >= 65 && gender =="M" ){ condition.innerHTML = "* Please fill out From A"; } else if( age >= 65 && gender == "F" ){ condition.innerHTML = "* Please fill out From B"; } else condition.innerHTML = "* Please fill out From D"; }

2:00 "Thank you for submitting your daughter" soo what if the user submit their son?

why he need to talk so long before writing the code? Kinda boring but i think i like what he taught in this video.

why did't you use this && instead of this || , ,you are checking the two fields of value not one, if any of the field is unfield just return false, lolllllllllllllllllllllllll coding, keep studying along with teaching
