I wonder to use SC.oEmbed to play sound from SoundCloud.But when I use it, I always get ERR_FILE_NOT_FOUND error.
I put my Source Code in Jsfiddle: http://jsfiddle.net/n2sVk/, it works OK. But when I save it to a HTML file and open it with Chrome, the error would be observed.
The Source Code is shown as below:
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
<meta charset="UTF-8">
</head>
<body>
<script src="http://connect.soundcloud.com/sdk.js"></script>
<div id="wrap"></div>
<script type="text/javascript">
SC.initialize({
client_id: "c202b469a633a7a5b15c9e10b5272b78",
redirect_uri: "http://connect.soundcloud.com/examples/callback.html"
});
SC.connect(function(){
console.log("connect " + "return");
SC.get("/me", function(me){
console.log("me.username:" + me.username);
console.log("me.description:" + me.description);
SC.get("/tracks", {limit: 1}, function(tracks){
console.log("get track return");
track = tracks[0];
console.log("track.uri: " + track.uri);
console.log("track.title: " + track.title);
SC.oEmbed(track.permalink_url,
{auto_play: true},
document.getElementById("wrap"));
});
});
});
</script>
</body>
Here is the error from Chrome:
GET file://soundcloud.com/oembed.json?auto_play=true&url=http%3A%2F%2Fsoundcloud.com%2Fyung-crusty-beats%2Fmystic-juice net::ERR_FILE_NOT_FOUND sdk.js:1
oEmbed response: null
This happens because when you are testing it locally, you are on "file:///" protocol.
The library's source code is using // in place of the protocol – this lets the library work on both http and https. However, when you access your code from a file as opposed to a webserver, the oembed function will probably not work.
The solution will be to run a local web server, such as Python simple server, which you'd run from the root folder of your project:
python -m SimpleHTTPServer

Following coffee-script code:

This sounds like a problem for source maps.
When you compile your CoffeeScript, you can generate a source map by specifying the -m option:
coffee -c -m so.coffee
In browsers that support source maps (e.g. Chrome), the CoffeeScript file will appear in the Sources tab, and errors and log statements will refer to the corresponding line in the CoffeeScript file.
For more information, check out the HTML5 tutorial on source maps, and a short article about using source maps with CoffeeScript.
If you have a source map, you can also use it to parse a stack trace string and refer back to the original uncompiled file as outlined in this question.
I stuck on publishCreate message broadcasting and have no idea what I am doing wrong.
Created a simple model called Sample:
module.exports = {
attributes: {
device: 'string',
value: 'float'
},
afterCreate: function(sample, next) {
console.log("afterCreate called");
Sample.publishCreate({value: sample.value});
console.log("publishCreate sent");
next();
}
};
Didnt find in the documentation if models do publishCreate automatically so I added afterCreate.
Then I created following view:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="/styles/iphone.css">
<!-- Bring in the socket.io client -->
<script type="text/javascript" src="/js/socket.io.js"></script>
<!-- then beef it up with some convenience logic for talking to Sails.js -->
<script type="text/javascript" src="/js/sails.io.js"></script>
<!-- listen on socket.io for incoming messages -->
<script type="text/javascript" src="/js/app.js"></script>
<script type="text/javascript">
socket.on('message', function(msg){
alert('message received');
});
</script>
</head>
<body>
<div class="block" style="height: 320px;">
<div class="centered">
<h1><%= temp %>°</h1>
</div>
</div>
</body>
</html>
Theoretically now if I call the view in the browser and then in the other browser tab I call
http://localhost:1337/sample/create?device=AA&value=10.0
a message should be received on the client side in the above view but nothing happens.
I know from the messages that sockets are connected and publishCreate is called when new Sample is created.
What can be a reason? Do I also have to do something in the controller when calling res.view() ?
Did you explicitly declare your publishCreate in your create action of the controller?
'create': function(req,res,next){
Sample.create(req.params.all(), function sampleCreated(err,sample){
if(err){console.log(err); }
Sample.publishCreate({
id:sample.id,
device: sample.device,
value: sample.value
});
});
},
You should probably explicitly declare the data points that you want to publish. Here I've set the Id, device, and value to be published explicitly. Blueprints and automatic controller mapping is useful, but it might be really unstable and unreliable sometimes, especially with the lack of documentation. Better to be specific.
The likely problem here is that the controller action that contains the subscribe call is being run in response to an HTTP request, not a socket request. req.socket is meaningless when the request is via HTTP; the server has no idea what socket was used. In order for subscribe to work, the request has to be made over a socket connection, e.g. using the socket.get method in the sails.io.js library.
we would need to use Model.watch(req) in order to subscribe to Model class. Then we will receive publishCreate() broadcasts.

I've recently started experimenting with AngularJS. I am building a simple html5 application that updates a MySQL database.
[index.html]
<!DOCTYPE html>
<html ng-app="MyProject">
<head>
<title>My Project</title>
<link rel="stylesheet" href="css/main.css" type="text/css">
<script src="lib/angular-1.0.1.js"></script>
<script src="lib/angular-resource-1.0.1.js"></script>
<script src="js/controllers.js"></script>
<script src="js/services.js"></script>
</head>
<body>
<div id="main-content" ng-view>

I used the Slim framework to create a Rest Interface. My database has currently one table named location_types with two columns id and title. I have tested the Rest service in the browser so under api/locationtypes I get the following JSON:
[{"id":"1","title":"Airport"},{"id":"2","title":"Bus Station"}]
I create the service in AngularJS using the following code:
[services.js]
angular.module('myDB', ['ngResource']).
factory('LocationTypes', function($resource) {
var LocationTypes = $resource('http://localhost/project/api/locationtypes', {}, { query: {method: 'GET', isArray: true}});
return LocationTypes;
});
I also use the following code to create the app module:
[controllers.js]
angular.module('MyProject', ['myDB']).
config(function($routeProvider) {
$routeProvider.
when('/locationtypes', {controller: LocationTypesCtrl, templateUrl:'forms/locationtypes.html'}).
otherwise({redirectTo:'/locationtypes'});
});
function LocationTypesCtrl($scope, LocationTypes)
{
$scope.locationTypes = LocationTypes.query();
}
The problem is that I get no results after querying the service. The locationTypes array is of zero length when I debug. I am using the latest AngularJS release [1.0.1]. What do I miss?
Is your URL really 'http://localhost/project/api/locationtypes' or is it an external server?
If its external, then you have a CORS (cross origin) issue. Unless I'm missing something it looks correct to me.
Probably a CORS issue like Dan said.
You can bypass this by adding the following to your module config.
.config(function($httpProvider){
delete $httpProvider.defaults.headers.common['X-Requested-With'];
})
Deleting the headers set by Angular should resolve the CORS issue.
You should also add a .htaccess file in your api folder. And add this:
Header set Access-Control-Allow-Origin "*"
I don't understand how to use XUI tween. On the xui website, they give the following example code:
x$('#box').tween([{left:'100px', backgroundColor:'green', duration:.2 }, { right:'100px' }]);
What is that supposed to do? I created a <div id="box"></div>, ran the line of js code above, but nothing happened. Here's my complete code:
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<script type="text/javascript" src="xui.min.js"></script>
<script type="text/javascript">
x$('#box').tween([{left:'100px', backgroundColor:'green', duration:.2 }, { right:'100px' }]);
</script>
</head>
<body>
<div id="box"></div>
</body>
</html>
Nothing happens...
So, XUI's tween seems to be a work in process. In fact, in the master branch code on GitHub you find:
// queued animations
/* wtf is this?
if (props instanceof Array) {
// animate each passing the next to the last callback to enqueue
props.forEach(function(a){
});
}
*/
So, in short, the array-based tween properties appear busted at the moment. In addition, XUI's tween seems to be a little flakey when dealing with properties that are not currently set on the DOM element. (For example, setting the background-color on a transparent element turns it black...rather than the intended color.)
That said, the single tween and callback work well on previously set properties. So take a look at the following (and excuse the inline css):
<html>
<head>
<script type="text/javascript" src="http://xuijs.com/downloads/xui-2.3.2.min.js"></script>
<script type="text/javascript">
x$.ready(function(){
setTimeout(function(){
x$('#box').tween({'left':'100px', 'background-color':'#339900', duration:2000}, function(){
x$('#box').tween({'left':'500px', duration:2000});
});
}, 500);
});
</script>
</head>
<body style="position:relative;">
<div id="box" style="position:absolute;top:50px;left:500px;width:100px;height:100px;background-color:#fff;border:1px solid #000;">the box</div>
</body>
</html>
Because #box now has a css background-property and left position explicitly set, it is relatively easy to produce an effect similar to the one desired.
One-half second after the page loads, #box should spend 2 seconds moving from left:500px to left:100px while turning the background color from white to green. Then, using the callback, #box moves back to its original position at left:500px--taking another 2 seconds to get back.
Obviously, this does not answer your exact question but for those (like me) who stumble upon this, it provides a workaround for the time being.
How do you integrate CKFinder with the new CKEditor.
It is very underdocumented on the website, and i am literally getting nowhere.
A step by step guide would be greatly appreciate as, as far as i am aware.. this is the only free/good image upload solution for a wysiwyg editor that is any good. Can someone confirm?
Thanks
You can find a tutorial on integrating CKFinder with CKEditor here:
http://www.webshaolin.com/index.php?page=article&articleid=40
Try doing following steps.
1. Download CKEditor and CKFinder. Integrated code may be available on http://dwij.co.in/ckeditor-ckfinder-integration-using-php/
2. Put extracted code of both in one folder inside xampp as below.
3. Create index file (index.html) which will be containing the editor as below code.
<html>
<head>
<script type="text/javascript" src="ckeditor/ckeditor.js"></script>
<script type="text/javascript" src="ckfinder/ckfinder.js"></script>
</head>
<body>
<h1>CKEditor CKFinder Integration using PHP</h1>
<textarea id="editor1" name="editor1" rows="10" cols="80"></textarea>
<script type="text/javascript">
var editor = CKEDITOR.replace( 'editor1', {
filebrowserBrowseUrl : 'ckfinder/ckfinder.html',
filebrowserImageBrowseUrl : 'ckfinder/ckfinder.html?type=Images',
filebrowserFlashBrowseUrl : 'ckfinder/ckfinder.html?type=Flash',
filebrowserUploadUrl : 'ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Files',
filebrowserImageUploadUrl : 'ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Images',
filebrowserFlashUploadUrl : 'ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Flash'
});
CKFinder.setupCKEditor( editor, '../' );
</script>
</body>
</html>
so your folder structure will be something like this:
htdocs
|_integrated
|_ckeditor
| |_config.js
| |_...
|_ckfinder
| |_config.php
| |_...
|_uploads
|_index.html
Now open file config.php inside ckfinder & make following changes:
function CheckAuthentication() {
// WARNING : DO NOT simply return "true". By doing so, you are allowing
// "anyone" to upload and list the files in your server. You must implement
// some kind of session validation here. Even something very simple as...
// return isset($_SESSION['IsAuthorized']) && $_SESSION['IsAuthorized'];
return true; // not good option though; go for sessions
}
$baseUrl = 'http://localhost/integrated/uploads/';
$enabled = true;
$config['SecureImageUploads'] = false;
$config['ChmodFolders'] = 0777 ;
Now open url http://localhost/integrated/ and try uploading image.
Check the documentation site for your server language: http://docs.cksource.com/CKFinder_2.x
For example this part of the PHP docs: http://docs.cksource.com/CKFinder_2.x/Developers_Guide/PHP/CKEditor_Integration
And btw, CKFinder is not free, you must get a license in order to use it.
First you must have a textbox to convert to CKEditor:
<textarea id="newTextArea">Some text</textarea>
Then all you need is some javascript code for the conversion of this texteditor to a CKEditor instance and the integration of this editor with CKFinder.
<script type="text/javascript">
var newCKEdit = CKEDITOR.replace('newTextArea');
CKFinder.setupCKEditor(newCKEdit, '/ckfinder/');
</script>
The second parameter of the setupCKEditor function must be the folder in your website where you uploaded ckfinder.
