Javascript Tutorial - 7 - Changing and Adding Array Elements

[futureprogrammer27]

love all your tutorial!!!! thanks a lot :)

[imaverick07]

hey.. i can't display name[3]..while running the script it says undefined. it works fine upto name[2].

[DeDean16]

@imaverick07 an array starts counting at 0, so if your array is called myarray and has 5 elements, myarray[4] is the last element of that array

[iAckeh]

so much like lua :)

[JKTCGMV13]

How do you change the look of alert and prompt boxes?

[xzycan]

@rapblack2 You are wrong. THAT'S ALL I CAN SAY! BUCKY creates some of the best tuts you can ever have.

[Gizmotrold]

wow you teach better then my teacher witch have been a teacher for 15 years ..

probebly cause hes way faster to explain , and its hard for an ADHD guy like me :P hehe i thank you with all my heart ,

i was thinking to pay you online for skype teaching , what ya say?

[2yung4grey]

@Gizmotrold dont thik thats right. Your getting it for free. Right Now and 4ever.

[LordShiding]

So you use the array so you can use names[0-infinite]?

so if you enter

var names=new Array

names [0]="You";

names [1]="mike";

names [2]="and Greg";

alert (+names "Are all douchebags");

you get

You Mike and Greg are all douchebags

[RASHTG]

@LordShiding I haven't tried it but I don't think you gonna get anything. You may get an output if you use: alert(names + " are all douchebags");

Excellent!

Easy to follow, easy to understand, informative, and exceptionally planned.

Thanks a million.



[razban01]

These tutorials is very easy to understand, you're a retard if you don'y learn javascript with these videos. I wonder who is the one person that dislikes this vid? A retard perhaps?

[chad362wiley]

[gamersgonebad]

@chad362wiley We are so proud.

[Pleeb22]

@chad362wiley No you're 28...just stop...

[chad362wiley]

@Pleeb22 really? i just wrote that for youtube watch my x1 vid i did comentary, if you cant tell m 12, youre a fuckin retard

[T1melimit]

@chad362wiley I can tell you're 12 by seeing that you couldn't take that obvious (despite not funny) joke.

[chad362wiley]

All your videos are awesome your a life saver thank you

[mylifeis2coolcmc2]

Hey if you have a user and he gets to get the varriable but to make it 1,2,3,... you just make ...[0]="null" and then you just forget to put 0 in the line, works every time but calling the whole array

[kiychane01]

dont worry man... your one thumbs down was just some drunk dude... he must have seen two thumbs up :D

[dragonfighterz123]

Remindz me alot of C and C++

By the way I'm ten and I already know the basics of C C++ HTML and doing JavaScript.

Later I will learn LUA RUBY java python and maybe more.

[k32323]

@dragonfighterz123 who cares?

[HawxTeamDelta]

@dragonfighterz123 that makes you special?

[WhanaSeeWhatYouGot]

@dragonfighterz123 i know c/c++/c# html php and now doin' javascript + i can work with darkGDK and studying XNA but it doesn't make me any special couze i know that with basics u wont go far. It's anything special ^^ only hard works job. Think again what're u talking about.

[d1995a3]

I'd rather just use the normal Notepad.

[karlosoe]

ok good

[Scripter4ever]

Your tutorials are very helpful and awesome. ;) Thank you for teaching us JS.

[swordenium]

[redhotchilipepperize]

[ConsolidateDesign]

[YourMistakes]

what is the program you are typing in ??

[mane95]

[Valy18]

@mane95 try MSVS

[ashadow0309]

@mane95 Notepad==

[emperusDS]

Notepad++, you can find it easily on google.

[carlesju1]

Notepad++

[WAJMhome]

wild question: what if you want to add an element into the middle of your array but you don't want to overwrite something already there, you just want to shift all of the other ones over?

[DreamBiggy]

perhaps, you may just need to hold the existing value into a temporal variable, then append it back to the top array, i.e:

names[0]="tony"

names[1]="mike"

names[2]="greg"

var temp=names[2]

names[2]="new person"

names[3]=temp

*Correct me if i'm wrong.

[existenceisrelative]

Why not just re-order your numbers while adding one?

[PCGAMER42]

great lesson

[SamDGoodrick]

die.

[Wowccraft]

awesome...but where are you from? mild accent.

[cdipaolo1996]

lol lets think, the title of his channel is thenewBOSTON, leta think about that...

maybe it might be BOSTON?

lol

[canucksfan94]

lol lets think, the channel says Hometown: RALEIGH, leta think about that...

maybe it might be RALEIGH?

lol

[fireguy1919]

that definitly a boston accent cuz i know another youtube who is from boston and he's got the same accent

and ya, his website kinda gives it away too, just like cdipaolo1996 kindly pointed out...

[ro33han]

i belive a true question, not all this "wheres this guy from" would be as follows:

what would you do if batman smashed down your front door screaming:

" I LEIK CHOCOLAT MEELK!!!!"

[ilikechess1]

crystal clear quality awesome

[cdipaolo1996]
