[Ostepopsex]

WHO THE FRU! Say it like fruit without "it"

[JKTCGMV13]

if your doing the first "if" statement, then the ( ) can be right against the "if" without spaces. if your doing the "else if" statement, you need a space after the "if"

[90cdowns]

[wweFantasticHHH]

I could see "who the f are you" coming lmao

[bondservant4Him]

so you can compare strings in javascript unlike C?

[qazwsx0987654312]

dude this is getting pretty cool, i keep testing my own codes like branched off your own, i made this so its a prompt lol=)))))) im soo happy ttytytytytyty

[mikethedj4]

How would I do this if I was using OnClick and OnMouseOver, Out, etc: for onclick effects as well as hover rollover effects???

[neuromeditation]

Who the f are u - lol

[SuperMani2020]

Gr8 job dude

[PATRICKKASIE]

LOL when i open google chrome i always get the last pages back where i was on. i lost my focus for this clip (i clicked an other tab instead of this one) and it said: '150'later'bob'later'tina. what happened here?

[kurrethegs]

@thenewboston what kind of recording program are you using?

[IgnacioSantobar]

Please disregard previous stupid question. Got a little ahead of myself.

[Xenocide007]

random question, has nothing to do with the vid really, but i tryed to make a calculator type program, where you just enter two numbers and it adds them together, but when i do the plus sign it just puts the two numbers right next to eachother, the exact same code works when i replace the adition sign with any other math sign, but why wont it work with addition, and is there another way i can do addition?

[MrLiakuras]

@Xenocide007 in order do add the numbers you have to add this: *1 its the only way to work

[edmondxmosoon]

@Xenocide007 it is because javascript is doing a string concatenation on them. use parseInt( );

ex:

var num1, num2;

document.write(parseInt(num1 = prompt("num1?")) + parseInt(num2 = prompt("num2?")));

hope that helps

[mylifeis2coolcmc2]

so a question, if you want to have a name how do you make it correct like:

var name=prompt("name?");

so how do you get it true if you type in GREG but it is set to greg, how can you make it true without the use of else if???

[edmondxmosoon]

@mylifeis2coolcmc2 use the toUpperCase() or toLowerCase() method.

ex:

var name = prompt("name?");

document.write(name.toUpperCas­e());

[InspiredByColor28]

lol @ "who the f r u" lol. Great tutorials!

[rangeispow]

@gugglewuggle Silly, that just means you haven't saved it.

[gugglewuggle]

hey heres a tip if your using ++: if the tab icon goes red youy script has a fault in it

[123456789kamran]

how do you make it so if the condition is false, you get redirected to another page?

[zeificaiOn]

Just figured out why my script were not working I put elseif not else if.

[BrianMNDBPH]

stupid comment >> if I can only use else if 1 or 100 times, If I want to do it 2 times, I have to do it 98 more times "oh sob... oh cry."

[oliverjamescarr]

Did a plane fly over your house at the end?

[abhilabdas]

thanku

[carolinekershaw24]

none of your code works for me

[DualKong]

the hard part is functions, be prepared

[lordofthemonths]

who the f r u jeje

[spiceuvlife]

Thanks for your tutorials! Using only the first 10 I've created a "Guess the number" game! I just need to loop it and add a little randomness and it's done!

[JustaFreak15]

It seems like I can only do a single if and an else.

If I make an if/else if/else the action will not run. Nothing will happen.

I am using Internet Explorer. Is that the problem?

[sekulr]

probably not but i wouldn't use IE either way.

[101m4p]

You should always use === instead of ==. Because, for example:

""==false // return true!!!

""===false // returns false!

That is because === and !== do also compare the data type. Hope I helped, my english is not that good!

[ExtremeCardControl]

Thanks! :D

[ruffstylez]

"who the f r u" - nice :)

[logi37]

mozilla firefox?

[richgilb]

lol, "writing rhetorical questions with javascript"

[unlscrv2]

is it necesary to put { } before and after de alert....??

espero tu respuesta wee ajjaj

[omega9o]

yes that is the container for the code.

[patrick99e99]

no, if you have a single simple condition, you can have it on a single line:

if (blah) alert("blah!!");

... Also, there is a shortcut turnary syntax for if/else:

blah ? "blah!" : "no blah!"

That means, if blah is true (or exists), output blah!, otherwise output no blah!.

[bmxmd2]

Dude, I did the same exact thing, on Notepad++ but it still didn't work.

[QuantumAnomaly]

I wrote this piece of script and can't figure out why it's not working. (Not sure if YouTube will display code, but here goes...)

var password=prompt('Please enter your password.');

if password=='123' { alert('Thank you!');

}

else { alert('Your password was incorrect.');

}

[vbrshi]

hi you did not use braces () to the if condition so it is not working .

[BajanCreation]

dude put you brackets before like this:

If (password==123)

[QuantumAnomaly]

Thanks for the clarification!

[isaykatsman]

You are awesome!

[vvurx]

thank you man

 now i learned some basic of javascript

[solarlight361]

hey stevo

[CoolKidinTown07]

lmfao at "who the f r u" so funny LOL

[ifthruim]

I don't understand what program you're writing that in that colors the text. Tell me, please?

[thenewboston]

its called "notepad++"

type that in google and download it, its free! and its the best editor out there! i think i show how to download it in my first XHTML tutorial too if u need help

[iceemberpro]

@thenewboston yeah i have a linux console and if you save it as a java file it will flip colors onto your text editor as well lol i have no choice but to look at it change clolors

[retromelon123]

@ifthruim Hey, also, for anyone else having bother with this too. By default you probably won't get colours in your script. to get them you need to go to language>J>JSP. NOT javascript or java. Don't ask me why, i just figured it out.... hope it helps.

[thenewboston]

haha nevermind i just watched the tutorial again, i gotcha now

[frodo3332]

hello bobny

[thenewboston]

bobny? i dont get it

[frodo3332]

[TheSexyCeleb]

[Chrisevil]

[CMOODO]
