@all It appears I may not be down there for class tonight. I’m dealing with a plumbing leak in my apartment that is seriously no bueno. If I can get this resolved by 4, I’ll try to make it. If not, then I’ll see everyone tomorrow during lab time.

@wifelette

The front door is locked, FYI.

There's something jammed in there for now, but if it gets moved you may need to catch someone's attention...

matt

@mechlo

Door got closed. Let us in?

@JoeyHayden

The Ross Island is a parking lot, I'm gonna be about 10 minutes late.

@chiclechew

yeah I heard the Sellwood bridge is closed for the next 3 days, hence doubling Ross Island traffice

traffic.

Ivan Storck

@ivanoats

matt

@mechlo

hey @tsongas could you post up that example of the cards? preferable with the shuffle from the data structures last night

@preetdha

@tsongas Would you be mind posting slides for this week on Canvas? Thank you!

Benjamin Hrach

@bhrach

@all I'm in the middle of cleaning up a huge mess and moving to a different apartment. I'd be a serious jerk if I left my girlfriend to do this herself. I won't be down there for lab tonight. I will see all you guys next Wednesday for the final class. I'm very sorry.

Hey all, I just got this notice from tuts+ about their upcoming cyber Monday deal. I really liked their sublime text videos, so I was going to look into some of their others. @tsongas or @ivanoats, do you have any others you'd recommend? http://tutsplus.com/cyber_monday

@PolishZeus

I find myself circling the same two errors in my code. Is it bad to ask someone else to take a peek to offer insight? I'd consider myself a fairly big newb & the code is a mess---I'm just trying to get something that runs before enhancing it with textboxes or CSS

It is either "Unexpected end of input" on line 1 or "Unexpected token" of a semicolon on the very last line of my code

Mike (Mikey) Bedney

@PolishZeus

FIXED IT!!!WOOOOOOOT!

It doesn't do anything...but at least I'm not returning errors happy dance

@tsongas

@sfasano you might check out the courses in their javascript bundle http://tutsplus.com/bundles/javascript-web-app-launchpad.

Chris Tsongas

@tsongas

@preetdha and everyone else class 4 and 6 slide decks are now up in Canvas under Files (no class 5 slides).

Chris Tsongas

@tsongas

@OhYeahPortland you'll find that in the class 6 slide deck. I also posted links to examples from class in the Canvas discussions about class 4 and 6.

@bhrach

I’m grading assignments today and have suggested a free Code School course to a few of you. I found it really helpful in learning jQuery https://www.codeschool.com/courses/try-jquery

@bhrach

Here’s another handy resource that diagrams which HTML5 elements to use, if you get confused. http://html5doctor.com/downloads/h5d-sectioning-flowchart.png

@sfasano

@bhrach or another TA, I'm having trouble with some code. Could you take a look and either provide some feedback now or during class? I've included my issue in the comment on the gist. Thanks. https://gist.github.com/sfasano/82a3701b70e86478cc19

Ivan Storck

@ivanoats

@sfasano I am looking into it. I am getting a syntax error when you load the page, is that happening for you and is that the issue you are experiencing?

Stephen Fasano

@sfasano

@ivanoats That's likely my fault. I tried merging 3 files into 1 html file inorder to consolidate, and never tested it to make sure it ran.

Ivan Storck

@ivanoats

looks like you’re missing an opening html tag too

what error or behavior are you trying to fix?

paste your js into jshint.com - you’ll see some warnings about unmatched {

that’s probably the syntax error

Ivan Storck

@ivanoats

then look at your data types comparisons in line 67 https://gist.github.com/sfasano/82a3701b70e86478cc19#file-buttonclassissue-html-L67

there’s a reason jshint says always to use “!==“ instead of “!=“

Stephen Fasano

@sfasano

My issue is mainly summarized by this....

$('.first').click(function() {
alert("made it to 1");
$(this).addClass("second").removeClass("first");

});

$('.second').click(function() {
alert("made it to 2");

} );

I want to get two different alerts each time the button is clicked, but instead it runs the first alert twice.

Ivan Storck

@ivanoats

right - it comes down to line 67

Stephen Fasano

@sfasano

@ivanoats , I rewrote this issue in it's stripped down form without the "!=" syntax. Hopefully we can take a look during class. https://gist.github.com/sfasano/82a3701b70e86478cc19
