Please find 2 set of code blocks below and let me know which one is to follow and why?
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Set 1</title>
<link rel="stylesheet" href="css/jquery.mobile-1.2.0.min.css" />
<link rel="stylesheet" href="css/customStyle.css" />
</head>
<body>
<div data-role="page">
<div data-role="header" data-position="fixed"></div>
<div data-role="content"></div>
<div data-role="footer" data-position="fixed"></div>
</div>
<script src="js/jquery-1.8.2.min.js"></script>
<script src="js/customScript.js"></script>
<script src="js/jquery.mobile-1.2.0.js"></script>
</body>
</html>
and set 2 is....
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Set 1</title>
<link rel="stylesheet" href="css/jquery.mobile-1.2.0.min.css" />
<link rel="stylesheet" href="css/customStyle.css" />
<script src="js/jquery-1.8.2.min.js"></script>
<script src="js/customScript.js"></script>
<script src="js/jquery.mobile-1.2.0.js"></script>
</head>
(ie) which one is right, putting all the scripts at the top or at bottom?
Both of them are correct, only difference is how are you going to bind events.
In the first case, because HTML is already loaded into the DOM events can be bound directly like this:
$('#buttonID').on('click', function(){
});
Because button is already into the DOM, click event can be bound directly to it.
In the second case, because jQuery Mobile is loaded before page content all event binding must be done like delegation:
$(document).on('click', '#buttonID',function(){
});
This is a safer but slower solution. It don't require for object to exist to bind an event to it.
To make a story short, solution 1 is slightly faster.
First case to improve performance .... this is said to be general practise to keep javascript down the page ...so that content is loaded faster .... though no facts or analysis personally I have on same. Check this nice post sameelegantcode.com/2010/03/30/your-javascript-goes-where/
It will good to place all javascript at the bottom of the page. Never forget that page rendering can be delayed by javascript parsing/execution. Well, I believe you love to read http://developer.yahoo.com/performance/rules.html#js_bottom

Object blending is ON by default and you have to tap the button to turn off.
Most of the people using my AR will be first time users and won't know how to turn it off.
Is there a way to turn this off by default? I am not seeing a solution in the documentation.

I commented-out all the dialogs prompting for this and tested it on a phone that does not support it, because their code just automatically turns it off anyway. Same goes for that instant placement stuff which I think is just future-proofing by them for when the lidar devices (like Apple's) come out...
Here is the solution - add "&disable_occlusion=true" in the intent, e.g.:
Avocado;
I am having trouble getting flipbox to work. It displays, but I can't get the day/month/year to roll or move at all. It's frozen.
Same if I change the mode to timeflipbox, or durationflipbox -- they display when I click them but don't respond to any mouse or keyboard activity.

What's wrong with this code for the flipbox to be frozen? The only thing I can think of is that the js references are off, but I just downloaded them and I'm pretty sure they are current.
Any ideas?
figured it out... I just copied/pasted the css/js references from JT Sage's Datebox page source: http://dev.jtsage.com/jQM-DateBox/
Trying to learn webix (and javascript at all). Usually the common practice is loading javascript libraries at the end of the body.
The webix quick start doc says:
<!DOCTYPE HTML>// specifies document type
<html>
<head>
<link rel="stylesheet" href="../../codebase/webix.css" type="text/css">
<script src="../../codebase/webix.js" type="text/javascript"></script>
</head>
<body>
e.g. it loads the library in the head.
Questions:
the webix lib should be loaded in the <head>?
if yes, where should be loaded jQuery and twitter bootstrap?
and in what order?
You can place webix.js anywhere on the page. Just be sure that JS code that uses Webix API is used after webix.js loading
Normally scripts are placed at the end of HTML file as they only add some interactivity to the page. In case of Webix UI, without webix.js you will not see any content on page at all, so there is no benefits from putting webix.js at the end of page.
As for jQuery - if you plan to use webix-jquery integration you need to load webix.js AFTER loading the jQuery ( at the head, or at the end of file, doesn't matter )
You need to follow the below syntax or process for using the webix.
<!doctype html>
<html lang="en">

<script type="text/javascript" charset="utf-8" >
webix.ui({

})
</script>
</body>
</html>
Any dependencies must load on top webix.js, so that you can use them in your JS file.
I decided that I wanted to learn Jquery Mobile so I set up a test site and instantly came across a weird bug, from what I've read and seen data-theme="a" should be the white theme and data-theme="b" should be the black/grey one. However, for me it's the other way around.. Have I perhaps done something wrong when downloading the library onto my site? And does this matter or should I just ignore it?
The markup:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Testing</title>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.1/jquery.mobile-1.2.1.min.css">
<link rel="stylesheet" href="styles/style.css">
</head>
<body>
<div data-role="page" data-theme="a">
<h1>Testing</h1>
</div>
<script src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
<script src="http://code.jquery.com/mobile/1.2.1/jquery.mobile-1.2.1.min.js"></script>
<script src="scripts/main.js"></script>
</body>
</html>
This is what I get with data-theme="a":
I think it might be because your using a pretty old version of jquery mobile, I see you're referencing version 1.2.1, try version 1.4.5.
so basically I've been making a jQuery Mobile site, I've hit a lot of speed bumps but as soon as I start making progress, this happens!
The culprit: http://www.ehustudent.co.uk/cis21318140/cis3104/cw2/find-your-nearest-jospice.html
Whenever you click on a link, it just keeps spinning forever. It started happening when I actually got the map to work! The map was inline, so I put it in its own file and it's still happening.
IT STOPS HAPPENING WHEN I REMOVE THIS LINE OF CODE
<script src="map-kensington.js"></script>
Please help me :(. I need to put that line of code in the body or the map won't load, but when I do put it in there the page won't load!

Your script is failing with a 'google is not defined' error.
You need to add google script references to the individual map pages
Something like this:
<script type="text/javascript"
src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&sensor=SET_TO_TRUE_OR_FALSE">
</script>
