Try to remove this:

If you want utf-8 encoding there is no need for that since you are using:
<meta charset="utf-8">
connect() function was not exist. You forgot to insert it. please recheck again.

I get this error with a Parse.com JS App:
ReferenceError: Parse is not defined.
I really don't know why. Everything looks good to me. The files are linked correctly; I've checked this a few times. Is it not true, that I have to put my own JS right below Parse and it should work? This is what I've read here: Github Project
I use Chrome with the ripple extension. I serve the app via cordova serve
Any help much appreciated!

I'm sorry, I have no experience with Cordova, but in general I've seen problems like these being caused by live reloading of files or by asynchronous loading, which could be caused by cordova/gulp/nodejs.
Maybe you should use a require statement as shown on the Parse quick start guide: var Parse = require('parse');
When I try your html and javascript in jsfiddle it just works, so it should have something to do with the order of loading js files in your local "webserver".
The problem could be that the parse CDN was not found i.e . download the SDK and host it yourself instead
Just run into the same issue. You are most likely missing the reference to parse.min.js.
The reference is typically in your index.html file, inside the header:

I have tried running the javascript in a separate file and using init() onload but still doesnt fire?
Any ideas?
#tau can you check if there is file name called cordova.js in the folder www under <Your Project Name>\platforms\android\assets. If yes than replace that name js/phonegap-1.4.1.js to "cordova.js" in the html file.
Where is cordova.js in your project . Include cordova.js in hTML . remove this phonegap-1.4.1.js
If you have cordova project
I have these 2 html files (simplified to show the problem i'm having):

index.js:
var app = {
initialize: function() {
this.bindEvents()
},
bindEvents: function() {
document.addEventListener('deviceready', this.onDeviceReady, false)
},
onDeviceReady: function() {
app.receivedEvent('deviceready')
},
receivedEvent: function(id){
alert(location.pathname.substring(location.pathname.lastIndexOf("/") + 1))
}
}
Now when the app first starts it alerts with the message "index.html".
But after that, everytime I click the links to bounce between the 2 pages, the content is shown (the respective links to the other page) but I get no alert, meaning the javascript is not beeing loaded again. But if I refresh the page the alert shows up. I want this to load the javascript without needing to refresh the page.
Thanks,
This is happening because the device is already ready by the time you've selected the next page and thus it won't fire the "deviceready" event again.
I'd change the structure of both pages to:
<html>
<head>
<meta charset="utf-8" />
<meta name="format-detection" content="telephone=no" />
<meta name="msapplication-tap-highlight" content="no" />

My Calendar

</html>
Note I've moved index.js underneath jQuery mobile and removed the "onload" event.
Then I'd take advantage of the pagecreate event from jQuery mobile to trigger the alert
$(document).ready(function(){
app.initalize();
});
var app = {
initialize: function() {
this.bindEvents();
},
bindEvents: function() {
document.addEventListener('deviceready', this.onDeviceReady, false);
$(document).on("pagecontainershow", app.onDeviceReady);
},
onDeviceReady: function() {
app.receivedEvent('deviceready')
},
receivedEvent: function(id){
alert($.mobile.pageContainer.pagecontainer('getActivePage').data('url'));
}
}
I have this code, but all that happens when I move my slider is that the functions will restart. I want the function to update with the value of the slider position.
Edit: here is the entire page:

According to the jQuery Simple Slider docs on getting slider values, the event you need to bind to is a custom event called slider:changed, not the standard DOM change event.
If you modify
$('#slider').on('change', function(){
x = $(this).val();
});
to
$('#slider').on('slider:changed', function(evt, data){
x = data.value;
});
you should be able to copy the new value of the slider to your global variable.
I am using Phonegap and i want to use zoom in / out option on pinch using jquery mobile.
I have tried jgesture and hammer plugins for zooming it. Where i am wrong in this code?

Use hammer.js pinch, pinchin, pinchout
Here's the event documentation for their API on github:
https://github.com/EightMedia/hammer.js/wiki/Getting-Started
ALSO you've essentially made it not user scalable...:
initial-scale=1, maximum-scale=1, minimum-scale=1,
This line:
<meta name="viewport" content="user-scalable=yes, initial-scale=1, maximum-scale=1,
minimum-scale=1, width=device-width, height=device-height, target-densitydpi=device-dpi"/>
And then you use jquery to set it again:
$.mobile.metaViewportContent = "width=device-width, minimum-scale=1, maximum-scale=2";
No good, read up on it here:
