@andrewchar

ive been following from this site https://dev.twitter.com/web/overview

@salman-shahid

Ok, I know how to do it with your method.

In your HTML give a href id="twitter-btn"

Andrew Charlebois

@andrewchar

<a href="https://twitter.com/share" id=" twiterbtn" class="twitter-share-button" data-text="hey" data-via="Andrew_Char">Tweet</a>

Salman Shahid

@salman-shahid

Ok, one sec. I'll try to write this in one line then I will explain what it does.

Brb, two minutes.

$("#twitter-btn").data-text = getRandom(); }

paste that after generateBtn.onclick = function() { in your js section

Salman Shahid

@salman-shahid

I just updated it, so if you copied it before redo it.

I think that should work.

So when your button is clicked it changes the data-text type of your twitter button.

the data-text type is the text that is displayed in the field when you click on the tweet button

@andrewchar

Invalid left-hand side in assignment

Salman Shahid

@salman-shahid

Oh, $("#twiterbtn").data-text = getRandom(); }

Salman Shahid

@salman-shahid

It's because I spelt the id differently than what you had. If you copy paste that it should work.

How's that @andrewchar ?

Andrew Charlebois

@andrewchar

still saying invalid left hand side

Salman Shahid

@salman-shahid

Omg, it's too early, sorry I forgot!

See if removing the curly braces makes a difference (the one at the end of the line that I gave you

@gr4vy

I am trying to figure out why my onkeydown event handler function doesn't seem to work right... I am trying to get the little green square to move using the green arrows (works) and stop at the walls (doesn't work)... if you get to the wall you can keep pressing in the same direction as wall (the green square won't move, but the value of its position moves in logic creating console errors... http://codepen.io/gr4vy/pen/ZQqmBx

Andrew Charlebois

@andrewchar

@mynameissal what language code is that

Salman Shahid

@salman-shahid

JS but I don't know what's wrong with my code. I think there is also something wrong with your JS twitter code. I get an error when I try to run your codepen..

Salman Shahid

@salman-shahid

@andrewchar Yeah I'm getting no where with this..It's 4am here so I'm heading to bed. I'll see what I can do to help tomorrow.. I am all over the place right now..

Anyone know of any way to keep animations from all happening at once in a for loop?

I have it set up so it'll animate one of 4 divs depending on a value I got from i in for loop like this: for(i=0;i<arr.length;i++)

Problem is it just animates all 4 at once.

Or whichever ones the value corresponds with for the entire loop

Eran Finkle

@finklez

@keccakec don't do animation this way, CSS has 2 ways of animating, using transition and animation

you set a class with animation, you can set duration and delay, and even loops, then you can add/remove the class

Kevin Elser

@CoffeeCodeKevin

@finklez Thanks, jQuery animation is just easier syntax-wise for what I want to do, but that does seem like it would work a lot better.

Eran Finkle

@finklez

@keccakec you can also do it with jQuery, but for loop is a bad way for applying animations, if i'm not mistaken animation are applied async which means you'll have to use closures for it to work, but anyways it's a bad way, you can still use jQuery using delays for each div

Kevin Elser

@CoffeeCodeKevin

@finklez Yeah, I'm now using it to make sure the animations have about a 100ms delay between them. Unfortunately changing my animation functions to be css animations somehow broke my code? Either that, or codepen doesn't like me. Everything in my JS is now undefined.

I'm beyond confused considering I only changed the animation functions.

Even global variables are undefined

I forgot a semicolon.. fml.

Eran Finkle

@finklez

i guess it's ok then

css animation are much better, smoother, faster, even tho recent jQuery animation are prob using css animations as well, instead of the old position style

i'm working on my weather app and and the icons provided by OpenWeather seem really small... i've found better icons online that use font awesome but it says I have to put them in a Font folder... how would I do that in CodePen?

Jonathan Coleman

@jondcoleman

@ninja-ml you won't be able to put them into a folder on codepen. You'll have to store the images on an online service. Some people use imgur. I put them in my public dropbox folder and use the urls for them from there

Mark Lawrence

@ninja-ml

@jondcoleman thanks, that's what I thought, but I wasn't sure... I've used my public dropbox folder for images for other projects. I"m looking into using the Dark Sky API instead of OpenWeather API
