I cannot scale the image when moving the scale controller. It shows the following error:
Uncaught TypeError: canvas.requestRenderAll is not a function
Can please anyone help to solve this problem? I want the functionality to be implemented for image please refer to this. Here is my code:

Here is the result. You need to change the scale of the object on onchange event callback.

What is the correct way (to this date) to use JQuery Mobile and Phonegap together?
Both frameworks need to load before they can be used. How can I be sure that both are loaded before I can use them?
You can use deferred feature of JQuery.
var deviceReadyDeferred = $.Deferred();
var jqmReadyDeferred = $.Deferred();
document.addEventListener("deviceReady", deviceReady, false);
function deviceReady() {
deviceReadyDeferred.resolve();
}
$(document).one("mobileinit", function () {
jqmReadyDeferred.resolve();
});
$.when(deviceReadyDeferred, jqmReadyDeferred).then(doWhenBothFrameworksLoaded);
function doWhenBothFrameworksLoaded() {
// TBD
}
Here's how it worked for me, based on the example above

In order to use phonegap along with jquery mobile, you need to use it like this

<script type="text/javascript">

$.support.cors = true;
$.mobile.allowCrossDomainPages = true;
});
</script>

<link rel="stylesheet" href="jquerymobile/jquery.mobile-1.1.0.min.css" />
<script type="text/javascript"
src="jquerymobile/jquery.mobile-1.1.0.min.js"></script>
</head>
<script type="text/javascript">
// Listener that will invoke the onDeviceReady() function as soon as phonegap has loaded properly
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
navigator.splashscreen.hide();
document.addEventListener("backbutton", onBackClickEvent, false); // Adding the back button listener
}
</script>
<body>
<div data-role="page" id="something" data-ajax="false">
<script type="text/javascript">
$("#something").on("pageinit", function(e) {
});
$("#something").on("pageshow", function(e) {
});
$("#something").on("pagebeforeshow", function(e) {
});
</script>
<div data-role="header">
</div>
<div data-role="content">
</div>
</div>
</body>
As many people suggested using a deferred is an okay option as long as you don't care what order deviceready and mobileinit happe in. But in my case, I needed a few pageshow events when the application first loaded and mobileinit and by extension those pageshow/pagebeforeshow/etc events were all firing before deviceready finished, so I couldn't bind to them properly using a deferred on them. This race condition was not a good thing.
What I needed to do was make sure 'mobileinit' didn't take place until after 'deviceready' was already fired. Because mobileinit fires immediately when you load JQM I chose to use jQuery.getScript to load it AFTER deviceready was already finished.
<script src="cordova-2.2.0.js"></script>
<script src="js/jquery-1.8.2.min.js"></script>
<script src="js/async.min.js"></script>
<script src="js/app.js"></script>
<script>
document.addEventListener(
'deviceready',
function () {
$('body').css('visibility', 'hidden');
$(document).one("mobileinit", function () {
app.init();
$('body').css('visibility', '');
});
$.getScript('js/jquery.mobile-1.2.0.min.js');
},
false
);
</script>
The reason I'm hiding the body is that a side effect of this method is a half second of visibility of the original HTML document before jquery.mobile loads. In this case hiding it an extra half second of empty space is preferred to seeing the unstyled document.
I believe that it isn't necessary to use the deferred feature. (Maybe this isn't necessary with newer versions of phonegap?) I have this in the head of my index.html file and everything works fine. I do think that the order of including jquery, phonegap and jquery mobile are important.

To build on #Jeffrey's answer, I found a much cleaner way which hides the HTML markup until JQM has finished processing the page and renders the first Page element, since I've noticed that 1/2 second flicker of bare markup before JQM renders.
You only need to hide all the markup with css...PageShow() by JQM will toggle the visibility for you.
//snip
<style type="text/css">
.hide {
display:none;
}
</style>
//snip - now the markup notice the hide class
<div id="page1" data-role="page" class="hide">
//all your regular JQM / html form markup
</div>
//snip -- down to the end of /body

Loading of PhoneGap is slightly different than loading of jQuery. jQuery works more as a utility library so you include that and it is available for use immediately. On the other hand PhoneGap requires support from native code for proper initialization so it is not ready to use soon after included in the page.
Phonegap suggests to register and wait for deviceready event executing any native specific code.

Thank you .
Import the Font in pdfMake.
Afterwards update the vfs_fonts.js as described on github
assign pdfMake.fonts in your javascript
$(document).ready(function () {
pdfMake.fonts = {
'SolaimanLipi': {
normal: 'SolaimanLipi-Regular.ttf',
bold: 'SolaimanLipi-Medium.ttf'
}
};
var docDefinition = {
content: 'হ্যালো',
defaultStyle:{
font: 'SolaimanLipi'
}
};
$('.buttin_click_1').click(function () {
console.log('btn 1 clicked');
pdfMake.createPdf(docDefinition).open();
});
$('.button_click_2').click(function () {
console.log('btn 2 clicked');
});
});
I'm just trying to prove the concept of displaying a modal dialog in my SharePoint-hosted app page. I believe I've included the required js libraries and I give it more than enough time to load the libraries before I execute my function. The error I receive is:
Cannot read property 'hiddenButtonValueBeforeDialog' of undefined
I believe I have the libraries I need::
<script type="text/javascript" src="/_layouts/15/init.js"></script>
<script type="text/javascript" src="/_layouts/15/sp.runtime.js"></script>
<script type="text/javascript" src="/_layouts/15/sp.js"></script>
<script type="text/javascript" src="/_layouts/15/SP.UserProfiles.js"></script>
<script type="text/javascript" src="/_layouts/15/sp.core.js"></script>
<script type="text/javascript" src="/_layouts/15/sp.ui.dialog.js"></script>
Javascript:
function showDialog() {
var optDict = {
width: 800,
height: 500,
url: 'http://www.google.com',
title: "Upload your file"
};
try {
SP.UI.ModalDialog.showModalDialog(optDict);
}
catch (err) {
alert(err.message);
}
return false;
}
The error Cannot read property 'hiddenButtonValueBeforeDialog' of undefined occurs since the sp.ui.dialog.js is globalized JavaScript library and the required resource file SP.Res.resx has not been loaded on the client side (SP.Res.hiddenButtonValueBeforeDialog is generated from this file).
Solution
ScriptResx HTTP Handler is used to load the content of resource
files on the client side, the following line has to added:
<script type="text/javascript" src="/_layouts/15/ScriptResx.ashx?name=sp.res&culture=en-us"></script>
In addition, since there is a dependency for SP.UI.UIUtility
namespace in sp.ui.dialog.js library, the sp.init.js JavaScript
library has to be referenced:
<script type="text/javascript" src="/_layouts/15/sp.init.js"></script>
I added all these references in PlaceHolderMain
<script src="/_layouts/15/1033/init.js" type="text/javascript"></script>

Here's the fiddle link to it, works fine on Fiddle, but not from VS
I suspect the code you are using from VS is not the same as the fiddle version.
The fiddle code looks perfectly fine, but the code you posted here has a syntax error. You must use square brackets to create an array, not parentheses:
var availableTags = ["ActionScript", "AppleScript", "Asp", ... ];
