I can't load the JQuery in phoneGap in ios uiwebview - ios

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
Try this!!!

using Polymer with jQuery Mobile, works in Chrome, JQM events not firing elsewhere

In this example,
http://jsfiddle.net/7Ev43/2/ the inclusion of the first <script> line (<script src="http://www.polymer-project.org/platform.js"></script>) causes the jQueryMobile events pagebeforecreate and pageinit events not to fire, in Safari and Firefox. However, it works in Chrome.
Any ideas on how to amend this?
Further investigation:
It appears that on Firefox and Safari, platform.js is overriding addEventListener
At this point I'm not sure how to proceed further, any suggestions would be most welcome.
full example:
<!DOCTYPE >
<html>
<head>
<script src="http://www.polymer-project.org/platform.js"></script>
<link rel="import" href="http://www.polymer-project.org/components/polymer/polymer.html">
<script type="text/javascript" src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
<script type="text/javascript" src="http://code.jquery.com/mobile/1.4.3/jquery.mobile-1.4.3.min.js" type="text/javascript"></script>
<script>
$(document).on('mobileinit', '#mainpage', function(){
console.log("mobileinit");
})
$(document).delegate("#mainpage", "pagebeforecreate", function(){
console.log("pagebeforecreate")
})
$(document).on("pageinit", '#mainpage', function()
{
console.log("pageinit")
});
console.log('end of script')
</script>
</head>

<div id="mainpage" data-role="page" data-theme="b">

EmberJS and Jquery Mobile gives blank grey page

I am trying to build a small mobile app with JQuery Mobile and EmberJS.
This is actually a Rhodes Application (Rhomobile).
This is my Layout.erb:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Todo</title>
<!-- Ember Libraries -->
<script src="/public/js/libs/handlebars-1.0.0.js"></script>
<script src="/public/js/libs/ember.js"></script>
<script src="/public/js/libs/ember-data.js"></script>
<!-- Ember Application -->
<script src="/public/js/application.js"></script>
<script src="/public/js/router.js"></script>
<script src="/public/js/models/todo.js"></script>
<script src="/public/js/controllers/todos_controller.js"></script>
<script type="text/javascript">
$(document).bind("mobileinit", function(){
$.mobile.loadingMessage = false;
$.mobile.loadingMessageDelay = 300; // in ms
$.mobile.defaultPageTransition = 'none';
$.mobile.defaultDialogTransition = 'none';
$.mobile.ajaxEnabled = false;
$.mobile.pushStateEnabled = false;
$.mobile.loadingMessageDelay = 50; // in ms
});
</script>
<link rel="stylesheet" href="/public/jqmobile/jquery.mobile-1.3.1.min.css">
<link rel="stylesheet" href="/public/css/jqmobile-patch.css">
<script src="/public/jqmobile/jquery.mobile-1.3.1.min.js"></script>
<script src="/public/js/jqmobile-patch.js"></script>
</head>
<body data-platform="<%= Rho::System.getProperty('platform') %>">
<%= #content %>
</body>
</html>
As you can see I have disabled Ajax and PushState and stuff. This is my index.erb:
<script type="text/x-handlebars" data-template-name="todos">
<div data-role="page">
//My Template
</div>
</script>
Now when I try it, I just get a blank grey page. But no error in console or in Ember-Console (extension of Chrome). It even detects my views and controllers properly.
Then I try commenting the JqueryMobile CSS files and what I get is a page's height worth of blank space with "Loading" message and then I see my application below and it works fine. And if I remove JqueryMobile JS, I get the stuff but its not styled.
What is the problem?
It's kind of hard to say without seeing some more code of your app. If you only have the one template defined ('todos') it may be the case that Ember doesn't know how to kickstart the rendering of your app. You may need to define an 'application' template. It might be as simple as:
<script type="text/x-handlebars" data-template-name="application">
{{outlet}}
</script>

JqueryMobile loading external script in body does not solve my ajax navigation issue

I see some others (e.g. this post) have had trouble using external javascript scripts in JQuery Mobile - as of today I have joined their ranks.
I have a single external js script (controllers.js) which contains code that affects several pages on the site. It is loaded on every page of the site. I put the js file just before the tag it works fine on the initial page load. However when I navigate thereafter (using the JQM Ajax methods) all functions in the script stop working. I would have thought the script would remain in cache - but heyho. Anyhow there's an FAQ which answers this question and I've implemented their suggestion which is: "...to reference the same set of stylesheets and scripts in the head of every page." I have done this but when I do even on the first page load the js doesn't fire. There aren't page specific scripts - so the remainder of that FAQ does not apply.
My cut down html looks like this:
<!doctype html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<meta name="viewport" content="width=device-width,initial-scale=1.0">
<link rel="stylesheet" href="/static/jquery-ui-1.10.3.custom.min.css">
<link rel="stylesheet" href="/static/jquery-mobile/css/themes/default/jquery.mobile-1.3.2.min.css">
<script src="/static/jquery-1.9.1.min.js"></script>
<script src="/static/jquery-ui/jquery-ui-1.10.3.custom/js/jquery-ui-1.10.3.custom.min.js"></script>
<script src="/static/jquery-mobile/js/jquery.mobile-1.3.2.min.js"></script>
<!-- CSS: implied media="all" -->
</head>
<body>
<div data-role="page" id = "main-page">
<div data-role="header" style="overflow:hidden;">
</div>
<div id = "home" data-role="content">
<input type ='button' id = "some_btn" value="press me">
</div>
</div>
<script type="text/javascript" src="/static/js/controllers.js"></script>
</body>
</html>
and within the javascript file
controllers.js
$('#some_btn').click(function()
{
alert('button pressed');
});
Any ideas on what I may be doing wrong here?
Since the content in the #page is loaded dynamically via ajax, click will not work, since it only works on elements that are on the page when the script is called.
You need to use the .on() method:
$('body').on('click','#some_btn',function()
{
alert('button pressed');
});

jQueryMobile script runs twice on each pageload

I've been trying to get a script that inserts a div of text after the first and second paragraph of an article to work in jQueryMobile. It works on the first pageload, but on the second it loads the content twice, and the third time it's loaded three times, and so on.
The jQueryMobile libraries and my script is loaded in the head:
<script src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
<script src="myscript.js">
<script src="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.js"></script>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.css" />
Then I have
<body id="mobile">
<div id="wrapper" data-role="page">
And then the content of the page
My script is executed as documented on jquerymobile.com
$("#wrapper").live('pageinit', function() {
Am I missing something? Any help will be deeply appreciated.
try adding data-dom-cache="false" it should look like this
<body id="mobile">
<div id="wrapper" data-role="page" data-dom-cache="false">
As Clarence commented, a better solution is to move the <script> tag outside of the <div> with data-role="page"
<body id="mobile">
<div id="wrapper" data-role="page">
<!-- stuff -->
</div>
<script>
$("#wrapper").live('pageinit', function() {
// more stuff
});
</script>
</body>

Disabling Ajax in JQueryMobile

I'm trying to use JQueryMobile for an POC and it seems even though I use #using (Html.BeginForm()) instead of #using (Ajax.BeginForm()), ajax is enabled by default. It is being injected from one of the script files [ ~/Scripts/jquery.mobile-1.0a2.js ].
So what I want is to simply disable the Ajax for certain forms and do full form posts. This might be pretty abvious, but i simply cant get my head around it.
Any help is appreciated.

You have to set up the jquery mobile framework correctly to disable its auto - ajax
Here it's documented:
http://jquerymobile.com/demos/1.0a3/#docs/api/globalconfig.html
You could do something like this.
<html lang="en-us">
<head>
<title>#ViewBag.Title</title>
<link href="http://code.jquery.com/mobile/1.0a3/jquery.mobile-1.0a3.min.css" rel="stylesheet" type="text/css" />
<link href="#Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" />
<script src="#Url.Content("~/Scripts/jquery-1.5.min.js")" type="text/javascript"></script>
<script language="javascript" type="text/javascript">
$(document).bind("mobileinit", function () {
$.mobile.ajaxFormsEnabled = #ViewBag.EnableAjax;
});
</script>
<script src="http://code.jquery.com/mobile/1.0a3/jquery.mobile-1.0a3.min.js" type="text/javascript"></script>
</head>
<body>
<div data-role="page" data-cache="never">
<div data-role="header">
<h1>#ViewBag.HeaderString</h1>
</div>
<div data-role="content">
#RenderBody()
</div>
<div data-role="footer">
<h1>HTDE</h1>
</div>
</div>
</body>
</html>
Just add the following line to your page, obviously you have too add this under the document.Ready() function:
$.mobile.ajaxEnabled = false;
Note: If you are using Jquery Mobile beta, the configuration parameter for disabling ajax has changed.
http://jquerymobile.com/blog/2011/06/20/jquery-mobile-beta-1-released/
"Use ajaxEnabled to globally set auto-ajax handling."
Here's a link to the documentation for beta configs:
http://jquerymobile.com/demos/1.0b2/#/demos/1.0b2/docs/api/globalconfig.html
It took me way to long to figure this one out.
there is an easier way.. just figured it out from JqueryMobile documentation
http://jquerymobile.com/demos/1.0a3/#docs/api/globalconfig.html
all you have to do is,
ajaxFormsEnabled :false
