I have implemented a basic example with phonegap for android in eclipse. Than i went with ios environment. I have downloaded the cordova plugin and created a new project. Then i replaced www folder with the www folder that i have created for android. The index html file looks like this:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv=content-type content=text/html charset="utf-8">
<title>navigator.network.connection.type Example</title>
<script type="text/javascript" charset="utf-8" src="cordova-2.1.0.js"></script>
<script type="text/javascript" charset="utf-8">
// Wait for Cordova to load
//
// document.addEventListener("deviceready", onDeviceReady, false);
// Cordova is loaded and it is now safe to make calls Cordova methods
//
function helloworld() {
console.log('phone gap log...');
alert('Hello World');
}
</script>
<script src="http://debug.phonegap.com/target/target-script-min.js#anonymous"></script>
</head>
<body background="login.png">
<img alt="" src="login_logo.png" STYLE="position:absolute;LEFT:25px">

Kullanıcı Adı:<br> <input type="text" id="uname" ><br>

</form>
<button type="submit" onclick="helloworld()" STYLE="position:absolute;TOP:295px; LEFT:110px; WIDTH:100px; HEIGHT:50px" >GİRİŞ</button>
</body>
</html>
the style of the screen is same as with android. But when i pressed the submit button, i have got no action or no log in xcode or ios simulator. But it works on android and on eclipse. Why my simple code does not work on ios environment?
The onclick event isn't reliable in the Web View. You need to use ontouchstart or another event listener instead. The Apple Documentation lists the supported touch events.
So in your case you would have to change the button to something like this:
<button type="submit" ontouchstart="helloworld()" STYLE="position:absolute;TOP:295px; LEFT:110px; WIDTH:100px; HEIGHT:50px" >GİRİŞ</button>

This error disappears only when I remove the jquery mobile stuff...
Thanks in advance.
I would avoid JQuery Mobile in PhoneGap applications. I got to meet Andrew Trice, Adobe PhoneGap Evangelist, at a DC Droid Meet and listened to him present in a few Webinars. I've heard him say more than once that JQuery Mobile has huge performance issues. He recommended using other frameworks if possible. There are many other frameworks out there with good design, widgets, and samples that make them easy to learn. I think he even created his own called AppUI. Just look around and you'll find some really cool ones.
That error is definitely what it says: your cordova.js file is not being included correctly. Fix that first.
To answer your larger question: Angular, jQuery Mobile, and PhoneGap will play together but it comes with some big caveats.
The biggest issue is that the jQuery Angular Mobile adapter is currently abandoned while they invest time in building a better solution: angular-jqm. That means that the adapter only works with outdated versions of the libraries.
Second: those outdated library versions have some issues working with Windows Phone. These are fixable, too, but lock you into an even less maintainable version of them.
So here is the setup:
<script src="javascripts/vendor/jquery-mobile-1.3.1.js"></script>
<!-- this angular-1.0.6 includes a patch to support WP8 URLs: https://github.com/angular/angular.js/issues/2303 -->
<script src="javascripts/vendor/angular-1.0.6.js"></script>
<script src="javascripts/vendor/jquery-angular-mobile-adapter-1.3.2.js"></script>
Unfortunately I was never able to get partials to load via XHR so I included all pages in index.html document.
<body ng-controller="AppController">
<div data-role="page" id="first" ng-controller="FirstController">
<h1>First Page</h1>
<p>{{foo}}</p>
<p>Second Page</p>
</div>
<div data-role="page" id="second" ng-controller="SecondController">
<h2>Second Page</h2>
</div>
</body>
Then you need to switch off a few niceties in the JavaScript and set up your routes:
<script>
var so_example = angular.module('so_example', []).
config(function ($routeProvider, $locationProvider, $compileProvider) {
// turn off html5 mode so that we just navigate around using hashes
$locationProvider.html5Mode(false).hashPrefix("");
// allow for the odd URLs included in Windows Mobile PhoneGap
$compileProvider.urlSanitizationWhitelist(/^\s*(https?|ftp|mailto|file|tel|x-wmapp0):/);
$routeProvider.
when('/second', {
templateUrl: '#second',
jqmOptions: { transition: 'slide' }
}).
when('/', {
templateUrl: "#first"
});
}).
controller("FirstController", function ($scope) {
$scope.foo = "Hello, World!";
}).
controller("SecondController", function ($scope) {
});
</script>
Now you need to leverage the Cordova library before you bootstrap Angular to your HTML:
var app = (function () {
function onDeviceReady() {
angular.bootstrap(document, ['so_example']);
$.mobile.phonegapNavigationEnabled = true;
}
return {
initialize: function() {
document.addEventListener('deviceready', onDeviceReady, false);
}
};
})();
app.initialize();
I have an issue with vclick (or click) events when fired.
This is my html code:
<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no">
<title>Document</title>
<link rel="stylesheet" href="css/jquery.mobile-1.3.1.css">
<link rel="stylesheet" href="css/estilo.css">
<script src="js/cordova-2.6.0.js"></script>
<script src="js/jquery-2.0.0.js"></script>
<script src="js/functions.js"></script>
<script src="js/jquery.mobile-1.3.1.js"></script>
</head>
<body>
<div data-role="page" id="page">
<div data-role="header" position="fixed">
<h1>Data</h1>
</div>
<div data-role="content">
<div id="btn_comentar">
</div>
</div>
</div>
</body>
</html>
And this is my functions.js
$(document ).bind("mobileinit", function(){
$(document).bind("pageinit",function(){
$("#btn_comentar").bind("vclick",function(e){
console.log(e.isDefaultPrevented());
console.log(e.result);
console.log(e.relatedTarget);
alert("buttooon");
list_comments();
});
});
}
When I click my #btn_comentar, the data that I want to retrieve from function list_comments (sending via ajax) is duplicated; I realized that it was sending twice, and finally that it was something about when I clicked on my button.
This is the output from the console (twice):
false
undefined
null
and also the alert message box (twice) "buttoon";
I have tried some solutions like:
jQuery Mobile : replace click event by vclick event
but without success, please need some help
This is my new code and how it is now working, but it seems that without jQuery Mobile's default configuration

$(document ).bind("mobileinit", function(){
//$.mobile.allowCrossDomainPages = true;
});
functions.js
$(document).on("ready",function(){
$("#btn_comentar").bind("vclick",function(){
list_comments();
});
});
According to docs,
These enhancements are applied based on jQuery Mobile's default configuration, which is designed to work with common scenarios, but may or may not match your particular needs. Fortunately, these settings are easy to configure using the mobileinit event.
So that's what you need to use mobileinit for. For setting defaults like this :
$(document).bind('mobileinit', function(){
$.mobile.defaultTransition = 'slideup';
});
If my understanding is right, mobileinit is included/fired before jQuery Mobile's js is included. Assuming you done that, your script order must look like this :
<script src="jquery.js"></script>
<script src="custom-scripting.js"></script> <!-- This script must have mobileinit -->
<script src="jquery-mobile.js"></script>
At this point of time (when custom-scripting.js is loaded), pageinit wouldnt be defined.
It would be wise to add your pageinit event AFTER jQM script.
<script src="jquery.js"></script>
<script src="custom-scripting.js"></script> <!-- This script must have mobileinit -->
<script src="jquery-mobile.js"></script>
<script>
$(document).bind("pageinit", function(){
$(document).bind("vclick", "#btn_comentar" ,function(e){
console.log(e.isDefaultPrevented());
console.log(e.result);
console.log(e.relatedTarget);
alert("buttooon");
list_comments();
});
});
</script>
use once on pageinit:
$(document).on('pageinit') {
$("#btn_comentar").on("vclick",function(e){
console.log(e.isDefaultPrevented());
console.log(e.result);
console.log(e.relatedTarget);
alert("buttooon");
list_comments();
});
}
this should work
Another cause of double-vclicks I've encountered is due to Chromium synthesizing both touch events in addition to mouse events. I confirmed this cause by running the app in desktop Chrome's developer "device mode" (where the mouse cursor changes into a circle), confirming the problem exists, then toggling off device mode, and confirming the problem is "fixed".
jblas discusses it, partial excerpt:
Note that vclick does NOT suppress the synthesized mouse/click events that are generated by the browser because it does not know what context it is being used in, AND form input elements require the mouse/click events to function normally.
If you use a joystick or mouse (desktop), the alert will fire on the normal mouse click event.
If you want to suppress the click event while using touch, you have to call event.preventDefault() in your vclick handler. This will queue the request to kill the click event that follows but due to the differences in the way device vendors implement their events, and some bugs within different android OS versions, this turns out to be very hard to do. We try a couple of methods to figure out whether or not to kill a click event ... one is based on the element the touch event was triggered, on, and another is the position of the touch event. This is necessary because The browser does not necessarily dispatch the mouse events to the same element that it used for the touch event.
I embedded phoneGap in my UIWebView, referenced to this doc:
http://docs.phonegap.com/en/2.2.0/guide_cordova-webview_ios.md.html#Embedding%20Cordova%20WebView%20on%20iOS
And in the index.html, I write this sample code:
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
$(document).ready(function() {
alert(“jquery loaded”);
});
</script>
</head>
<body>
<h2>This is a heading</h2>
<p>This is a paragraph.</p>
<p>This is another paragraph.</p>
<button>Click me</button>
</body>
after the webview loaded, the "body" can be shown, but the alert can't be pop out. So the jquery.js is not loaded? Or something else is wrong?
Edit:
I added "http:" to the src, but not work.
Thanks!
change
alert(“jquery loaded”);
to
alert("jquery loaded");
or
alert('jquery loaded');
Add http or https to your code
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
The above should work for you.
Did you add the Cordova file?
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/javascript" src="./cordova-2.3.0.js"></script>
<script>
$(document).ready(function() {
alert(“jquery loaded”);
});
</script>
</head>
<body>
<h2>This is a heading</h2>
<p>This is a paragraph.</p>
<p>This is another paragraph.</p>
<button>Click me</button>
</body>
</html>
Also as much as phonegap uses HTML 5 it still requires a bit different style of writing your code. Everypage you make should all be in the same index page because Cordova loads at startup in your project. If you navigate away from the page Cordova needs to reload.
Did you copy jquery file at www forder (www/jquery.js). I use jquery too, mine is www/js/jquery.js

i want to try processing.js on an iOS application,
i have checked the projects on
http://procoding.audiocommander.de/ and
http://luckybite.com/iprocessing/
but none of them have an actual working example, so i went to create one...
SO... I have created a project and uploaded in
https://github.com/mako34/processing_iOS
my understanding is that all I need is just a wrapper for html5 canvas and js, for the
processing-1.4.1.js
to work??
my index.html works fine in a browser, not on the device!
my canvas works fine drawing a line on this test template
my js works fine on this test template
but doesnt work on the iphone actual web view,
So what is missing to make the sketch work?
thanks a lot!
here my index.html
<!doctype html>

<img id="testImage" src="iphonebattery.jpeg" />
<canvas id="myCanvas" width="320" height="200"></canvas>
<script>
var canvas = document.getElementById('myCanvas');
var context = canvas.getContext('2d');
context.beginPath();
context.moveTo(100, 150);
context.lineTo(450, 50);
context.stroke();
</script>
</div><!-- #container -->
</body>
</html>
First off-- you don't want to have two canvas tags. I recommend checking out the actual ProcessingJS website for better implementation: http://processingjs.org/
I have some tutorials on setting up Processing to compile to iOS and preparing your iDevice:

Hope this helps!
I have an application developed on iOS & Android using phonegap 1.6.0 & JQM 1.1.0.
Now i have used the same code for blackberry. I am having many pages within a single HTML. I just keep on changing the pages. But the issue which i am facing is that, Device ready is fired everytime i perform a changePage(). This doesn't happen in iOS and Android... Why is it happening?
Below is my code
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">

}
// register Cordova event listeners when DOM content loaded
function init() {

document.addEventListener("deviceready", onDeviceReady, true);
}
</script>
<title>Cordova API Sample</title>
</head>
<body onload="init()">
<div data-role="page" id="home">
<div data-role="header">
<h1>Here is the index page.</h1>
</div>
<div data-role="content">
<p><center>Below you may transition to our other pages.</center></p>

</div>
</div>
<div data-role="page" id="about">
<div data-role="header">

</div>
<div data-role="content">

</div>
</body>
</html>
In this you have to create one more js file for the on device ready.
To call your function in to this file
for new js file code i below.
//---------------------------------------------------------------------
// Cordova event listeners
//---------------------------------------------------------------------
function onDeviceReady() {
alert("Inside Device Ready");
}
// register Cordova event listeners when DOM content loaded
function init() {
console.log('init()');
document.addEventListener("deviceready", onDeviceReady, true);
}
call this script when you require.
