09:33:36 PDT

Question: Can you short the js script by using onClick in HTML?

Answer: JavaScript w as created a long time ago and is w idely used by all brow sers today, like Chrome, Firefox and IE. WinJS is a JavaScript UI library created by Microsoft for Window s 8 apps. It is built on top of JavaScript like

jQuery UI and Tw itter Bootstrap

09:37:43 PDT

Question: If he does another "onclick" assignment in his example, w ould it replace the current "onclick" event or

09:40:25 PDT

Question: What is the difference betw een JS and Java?

Answer: Java is an object-oriented language that runs on a Java virtual machine - it is not typically used in the

brow ser. It is similar to C# in technology. JavaScript is a prototypal scripting language that is used mostly in

brow sers, but is starting to be adopted in places outside of the brow ser like in NodeJS.

09:43:29 PDT Question: I thought the name tag is depreciated/not used in HTML5, only the id tag is supported

Question: Hi guys, as you are talking about HTML + CSS + JavaScript should w e assume that it is better to have

Javascript as server side code vs. C# ? Answer: I'd say it depends heavily on your needs. NodeJS can run JavaScript on the server -side, but in some cases

ASP.net w ould better suit your needs

09:49:32 PDT

Question: i think C# has its ow n lot of benif its. C# can do all those, w hich simple JS like Node.js can't do.

Answer: It really depends on style and w hat your needs are. Sometimes C# has a lot of boilerplate for something

simple you can do quickly in NodeJS.

09:49:53 PDT

Question: Can someoe please link the codepen that Mr. Foster is using right now ?

Answer: http://codepen.io/codefoster

09:52:09 PDT

Question: Tw o part question: 1) Are there any good resources on packaging a w eb app for off line delivery? My

clients customers are ship-board w ith limited or no bandw idth. 2) Does it even make sense to think about deploying a

w eb app in such a constrained scenario? Answer: Customers can side-load packaged WWA apps (HTML5 apps for Window s 8/8.1) for off line use in low -

bandw idth scenarios. With Window s 8, w e really w ant to make things f it your developer skills and not force you dow n

one API or another.

09:52:52 PDT

Question: I had to pop out for a second, so maybe I missed it, but are you going to talk at all about gracefully

handling html 5 in older brow sers that don't support it? I know there are some framew orks that help w ith this.

Answer: We're not going to be addressing that.

09:53:40 PDT

Question: Do you record the class?

Answer: yes. it w ill be available for dow nload as a full course in tw o w eeks

09:54:09 PDT

Question: Thanks Rob. Unfortunately a small percentage of my client's customers are running Win8. We (ugh) even

continue to support WinXP sites... Answer: That's going to be tough for the long-term to support a real packaged, off line app experience dow n to XP.

You might consider shipping a Node.js server/local w eb client app in that case, although that seems like overkill in

many w ays.

09:56:01 PDT

Question: In the f loating box example thing by codefoster, w hen you change the number of boxes, the size returns to

the default 100px until you move the f irst slider to update it. Is that because I'm using chrome or it w as intentional?

Answer: Not sure. I'll have to check it out. Feel free to fork and f ix it.

09:56:22 PDT

Question: I'm guessing that I am the dinosaur here since I earlier posted I speak DOS. Does anyone but me

remember FORTRA N? I actually see great similarities

10:15:27 PDT

Question: how to use the external css script in html

Answer: CSS: <link type="text/css" href="{URL to external CSS file" rel="stylesheet" />

10:19:00 PDT

Question: Rob, can you do phone on the low er SKU's or does it need Hyper-V for the WP emulator?

Answer: Good catch, you're right - Phone 8 development requires Win8 Pro because of the Hyper-V requirement.

Just looked it up on MSDN.

10:21:58 PDT

Question: What should I do w hen my PC doesn't support Hyper-V? Which part needs a upgrade?

Answer: It's generally either a BIOS or processor issue. Many of the low -end processors don't physically include

some of the required features. Other times, BIOSes disable Hardw are Virtualization features as w ell. Check your

boot-time setup for such Hardw are Virtualization settings.

10:24:16 PDT

Question: I'm currently learning C# but not sure w hat console app can really do for me lol.

Answer: You could try to make a Window s app instead of a Console app?

10:24:31 PDT

Question: @Rob speaking about the WP emulator - can I use it to test how my w ebsite w ould look on phone? Or is it

limited to loading apps?

Answer: For sure! And actually, w ith Visual Studio 2013 Update 2 + Window s Phone 8.1, you can directly debug

your w eb site for things like responsive design and see your DOM explorer / JavaScript debugger. You can also build

things like ASP.NET applications that your phone can access via localhost, and have them being accessed from a

client app (for example, if you build a WWA or XAML app, it can access that service via localhost as if the service

w ere running on the phone).

10:25:08 PDT

learn w ith him. Here's the question: building w eb apps using responsive layout is good, but it w ould be better to have

this as a native App. Is this possible? (make a WebApp a Native App using HTML+CSS+JS)?

10:46:07 PDT

Question: @Rob, back on the Window s 7 question...tw o people asked questions, so I don't know if your answ er applied to my question. On the Window s store, codeShow is not available for Window s 7. So I'm assuming that only

part of the answ er applied to Window s 7, namely, "...or get the solution at codeshow .codeplex.com".

Answer: codeShow is a Win8/8.1 app. You can't run it on Win7.

10:47:28 PDT

10:54:16 PDT

Question: Hey Sean, so for f lexbox, Jeremy scrolled through div w ith text in them. I am guessing those w ere loaded

w hen the page w as loaded. But could those div be loaded via ajax w hen the div comes into focus? Does f lexbox

support ajax?

Answer: f lexbox does not have anything to do w ith ajax. That is, if you designed your ow n UI control to render those

boxes, you probably need to know at least how many to render before you draw them on the screen. Whether or not

you need to w ait for a netw ork response has to do w ith your design.

10:54:17 PDT Question: so html5 replaces xhtml

Answer: Yes.

10:55:15 PDT

Question: So the takeaw ay is, w hen in doubt "f lexbox"?

w ith f lexible box models and such

10:55:37 PDT

Question: I meant to help it w ork correctly in older brow sers? Answer: One of the great parts about CSS is the cascading nature. You can start w ith older brow sers style rules f irst,

and then override them w ith new er style rules. New rules w on't be understood by older brow sers. You don't need to

duplicate, just order them correctly.

10:56:49 PDT

Question: I've heard that some w eb brow sers are still not compatible w ith HTML5. Is this correct and w hat w ould be

your recommendations for cross-brow ser compatibility?

Answer: HTML5 is mostly supported in all modern brow sers. There are limited HTML5 features that are not yet

w idely supported. In general, if you use a popular w eb framew ork, these issues are solved for you. Google Polymer is

a good example. WinJS is also w orking on this issue.

10:57:18 PDT

Question: So order them older to new er?

Answer: http://w ww.w3.org/TR/css3-transitions/#animatable-css

11:14:24 PDT

Question: What propreties can be changed by animation? Can a text change it's color? Can I make element to fade

out by animating hidden property?

Answer: Almost all color/size/position properties can be animated. Some properties are better performing, though. I

recommend using opacity for hide/show animations. See: http://msdn.microsoft.com/en-

us/library/jj680148(v=vs.85).aspx

11:22:10 PDT

Question: if you search for red text for example, w ill it recognise the text as red as soon as the transition begins, or

only at the end?

Answer: If you mean "search for red text" by using a CSS style selector of .redtext or doing a querySelector in

JavaScript... then the answ er is that it w ill f ind it right aw ay... the class is applied to the element and THEN the

transition runs, but the class is available right aw ay

11:22:43 PDT

Question: I missed Jeremy's answ er on how he w ould apply those transformations prior to the current css w ay

Question: Thank you for that info (transform origin)

Answer: transform-origin is the actual CSS property

11:30:10 PDT

Question: Can transform also do mirror affects?

Answer: Good question. I feel like perhaps it does, but I can't remember. Can you search it and report back?

11:30:42 PDT

Question: So, 'transforms' handle changes in space, like rotation and scale, and 'transitions' handle time, the

duration of change?

Answer: Mostly correct, I'd like to clarify: transforms are the actual transformations to position, size or color. the

transition is the timing function and duration.

11:30:59 PDT Question: isn't orientation related to north being 0?

Answer: Sort of, but I believe the question w e attempted to answ er w as more about an origin... a rotation point or a

skew point or w hatever

11:31:14 PDT

Question: Can't w ork. Skew X and Skew Y are just one-factor versions of Skew (X, Y) if I recall directly. Sadly, no Z

axis there...

Answer: Dang. Thanks.

11:32:00 PDT

Question: Is rotation & transform fully supported in IE w ithout requiring w ebkit

Answer: Yes. You can check out caniuse.com to see w hat w orks w here

11:32:34 PDT

Question: Can w e do a transition in tw o stages, for example Skew X positive for 1 second then negative for 1 second

Answer: That w ould be an animation, and the answ er is yes. You can animate by as many keyframes as you need

11:32:59 PDT

Question: Can't w ork. Skew X and Skew Y are just one-factor versions of Skew (X, Y) if I recall directly. Sadly, no Z

11:35:46 PDT

Question: differnece betw een developing app in html,css,javascritp and C#.Xaml

Answer: XAML is like HTML, it's still markup but the elements and attributes have different names. There is no CSS

equivalent in XAML. C# is heavily object oriented w here as javascript is prototypal and highly dynamic

11:37:22 PDT

Question: so scale(1) nothing w ill be changed ? Thanks

Answer: Correct

11:37:56 PDT

Question: scale an image to simulate a click

Answer: Perfect example

11:38:52 PDT Question: .trans is a class right but i dont remember w hat # is called... is it just ID? Or some other name in CSS?

Answer: # is the symbol for an ID selector

11:39:02 PDT

Answer: Make sure you're using the correct vendor-prefixes in the CSS

11:39:51 PDT

Question: Can you use the transform on a ID selector as w ell? or does it have to be a class?

Answer: An ID selector w ould w ork f ine... any selector w orks

11:40:18 PDT

Question: Wouldn't scaling up a group of elements see them overlap each other?

Answer: No, it w ouldn't. It takes the group of elements AS RENDERED and scales it up. Great question.

11:40:20 PDT Question: Wouldn't scaling up a group of elements see them overlap each other?

Answer: really only if they w ere position absolute

11:41:08 PDT

11:43:01 PDT

Question: Can I use hover or onclick of one element to apply - or start - the animation or transformation of another

element? ie. create zoom in / zoom out buttons for some other element? Or can I do so w ith JavaScript?

Answer: Yes - you could use :hover pseudo-selector, or if you w ant to respond to click you need to add a click

handler. In the javascript case, you can toggle a class on the element you w ant to toggle betw een states

11:43:42 PDT

Question: How do you rotate images?

Answer: Like he's saying now ... w ith a transform property (i.e. transform: rotateX(10deg))


Q&A Log


11:44:06 PDT

Question: how can w e beam and scale at the same time? Answer: The transform property can take multiple transform statements separated by spaces.

11:44:20 PDT

Question: can you use translate w ith a transition to get a slow movement effect or is that done better in JS?

Answer: Depends if you need to know the position or interrupt the animation. If it is a simple animation that should

alw ays play, then CSS transition w ould have better performance

11:44:58 PDT

Question: Will "translation" takes elements our of f low ?

Answer: No. If you translate a w ord out of its place a hole w ill be left.

11:46:54 PDT

Question: If you scale a w ord and make it small, it sets in the middle vertically. How do you get it to set on the

bottom like the other w ords?

Answer: change the transform-origin. I believe the value of 100% w ill w ork.

11:47:35 PDT

Question: if you have a translate on a hover w ill the element untranslate if the hover is broken on translate?

Answer: Yes, if you use the :hover pseudo class to apply the transform, it w ill reset w hen you unhover

11:48:31 PDT

Answer: transform-origin: 0

11:48:56 PDT

Question: DonP: Would jQuerry do the same action to an object as Transform as Michael is illustrating.

11:51:05 PDT

Question: There screen show a scrollbar at the bottom of code show but my w indow s 8.1 enterprise has no scroll

bar

Answer: It depends on w hether you're using a mouse or not. If you use a mouse it show s the scrollbar. The solution

to the issue you raise is to lead the user's eye off the screen by clipping the content, but it's tough to alw ays clip the

content in the demo section of codeShow because it's of variable w idth.

11:52:18 PDT

Question: is it like mathematics that w hatever inside parenthesis is done f irst

Answer: There is an implied order of operations in JavaScript and order of evaluation in CSS. I don't think you can

generalize "parenthesis are f irst"

13:26:10 PDT

Question: Is the WinJS object a part of IE? Or is it from a javascript library? Answer: WinJS is its ow n JavaScript library. It started as a WWA framew ork, but has now moved to be cross -

platform: http://try.buildw injs.com/

13:27:12 PDT

Question: Can I access WinJS library inside w ebsite or is it Win8 only library?

Answer: You can use the open-sourced WinJS project for w eb pages. It is currently under development to go cross -

brow ser. Many of the brow sers are already supported: http://try.buildw injs.com/

13:29:38 PDT

Question: So promise is actually a w rapped subroutine that interrupts itself to return intermediate status to main line

of code and allow the main line to process the sub's status and then return control to the subroutine - w hich picks up

w here it left off before reporting status?

Answer: This is a usual side-effect of using promises, but it is not its primary purpose. A promise is a w ay to

coordinate several async/sync tasks, so that they evaluate in a certain order or w ith specif ic timing.

13:31:11 PDT Question: I missed a tip around using promises outside the WinJS w orld. on http://w ww.caniuse.com i saw that

native promise is not supported in IE so far at all. You mentioned JQuery deffered method.

Answer: I believe ECMAScript 6 is proposing native Promises as part of JavaScript. WinJS has a promise

implementation that is built using pure JavaScript. I've heard jQuery promises are even faster than some native

brow ser implementations. The point is many framew orks have their ow n implementation of promises or futures.

13:33:05 PDT

Question: How is the variable "localstorage" defined to make it w ork like that? Or is 'localstorage" a key w ord?

Answer: There are a few reserved objects on w indow : http://msdn.microsoft.com/en-

us/library/ie/bg142799(v=vs.85).aspx

13:35:56 PDT

Question: Can you retrieve data from local storage if you go back to the page using a different brow ser? Ie, go to the

page in ie and go back later in chrome?

Answer: No, localStorage is managed by each individual brow ser, not the OS

13:36:11 PDT

Question: Where is local storage located on the client machine? Will an app need permission to use it?

Answer: This depends on the brow ser. The permissions are set in the brow ser.

13:36:34 PDT

Question: Is the previous data erased?

Answer: Yes, it is overw ritten. You can see some more info here about clearing data: http://msdn.microsoft.com/en-

us/library/ie/bg142799(v=vs.85).aspx

13:37:01 PDT

Question: w hat if I have multiple tabs opening different w eb sites, w ill the storage be corrupted by each other?

Answer: Please refer to this page, it talks about how the objects are shared betw een tabs

13:37:47 PDT

Question: can you know how much you can store on the machine?

Answer: It varies by brow ser and user settings. Please refer to this page: http://msdn.microsoft.com/en-us/library/ie/bg142799(v=vs.85).aspx

Question: Can local storage be disabled by a client? Answer: Yes, it's important to check if there is storage available

13:45:29 PDT

Question: SeanLee, Actually there's a w ay to use CSS only to achieve such effect w here you hover over one div and

another div changes. You just need to have nested divs and refer via CSS to them in such a w ay: div1:hover #div2 {

... } Anyw ay, the solution is rather specif ic than general and not so "elegant"

Answer: I believe you're referring to a solution w here you style div1:hover in a w ay that affects div2, but that's hardly

a useful solution

13:48:24 PDT

Question: Regarding the indexedDB - is there any persistency at all? Can I make a database, store it in local storage

Answer: This is abstracted by the brow ser

13:53:13 PDT

Question: Can I know w hat is Fiddler Web Debugger? There w as an hour-long netw ork outage from my side.

Thanks.

Answer: Fiddler is a tool to help you debug netw ork traff ic. It is especially useful if your app/w ebsite makes several

w eb requests and you need to debug the packets/responses

13:56:26 PDT

Question: Does the w ebsocked lead to JS file? Or can I open a w ebsocket to, say, perl CGI script or ASP.NET dll?

Answer: The WebSocket uses TCP, so as long as you can handle TCP requests, you can communicate w ith the

socket

13:57:00 PDT

Question: @SeanLee: Fiddler seems to be similar to Wireshark, but w hich one is recommended?

Answer: I like Fiddler or even the one built in to IE F12. I guess it's personal preference. Fiddler w orks w ell w ith

Window s Store apps too.

13:57:21 PDT

Question: What project type in VS2013 relates to the w eb development topic today?

Answer: Window s Store JavaScript apps!

13:58:06 PDT Question: How does Geolocation w ork w ith a desktop?

Answer: The OS usually has a location provider that uses available info. In the case of Window s, using IP address

and available w ireless netw orks can get a pretty good location of the user

14:09:34 PDT

Question: Stores = Window s Store JavaScript apps (sorry)

w eb server in the app, but you do have access to the app package files via the ms-appx:// f ile protocol

14:11:19 PDT

Question: Are there limits to how many sockets can be opened at the same time? Answer: There are limits to the number of HTTP connections that can be open. The default on Window s I believe is
