Why can't play youtube chromeless player in chrome extension? [duplicate] - google-chrome-extension

I'm newbie at chrome extension. I'm making chrome extension that play youtube chromeless player.
It worked on chrome web browser. But, it isn't working on chrome extension.
I tested local .swf file. That is worked on chrome extension.
I think, chrome extension can't call onYouTubePlayerReady().
So I called window.onYouTubePlayerReady() after swfobject.embedSWF(). But, it isn't worked at ytplayer.loadVideoById("xa8TBfPw3u0", 0); with error message.
The error message was Uncaught TypeError: Object #<HTMLObjectElement> has no method 'loadVideoById'.
Is there a problem in manifest.json? Or in YouTube API? I don't know why isn't working on chrome extension.

Please help me.

Recently I've encountered the same issue when working on a Chrome extension. When testing, the calls are simply not triggered. Until I've read this:
To test any of these calls, you must have your file running on a webserver, as the Flash player restricts calls between local files and the internet.

I suspect the problem is with the way I coded chrome.storage.get(), but I couldn't find the API reference, only an example of how to call it. I'm pretty sure I coded the call to chrome.storage.get() correctly, though. What am I missing?
It turns out that I needed to clear the errors after correcting a missing UI element. I don't understand why Google requires users to clear the errors before reloading the extension; the reload should clear them.

Is there a way to play background music using Google Apps Script?

I am creating an add-on which would ask the user to select music from a list and it would play it as background music. But previous posts show a sidebar with the user manually pressing the play button. I am wondering if there is a way to play it with Google Apps Script only. Also what would be helpful is if there was a volume property to set the volume?
My Code:
function onOpen(){
DocumentApp.getUi()
.createMenu("Background Music Add-On")
.addItem("Select Music","music")
.addItem("Set Volume","musicVol")
.addToUi();
}
//music selection
function music(){
var musicName = DocumentApp.getUi()
.prompt("Please select one of the music names:\n\nElevator Music,\nLeaf Rag.\nso on...")
switch(musicName){
case "Elevator":
//code to play music Elevator
break;
//So On
}
}
Playing music from a Playlist stored on your Google Drive
This script allows you to store mp3's on your Google Drive. It allows you to select which files you wish to listen too via a playlist. You must start the playlist the first time manually but then the rest of the selections play automatically. The script converts the mp3 files into dataURI's and loads them into the audio element. You can skip over the current selection and you can restart the playlist when it completes.

Please read through the code. You need to add a music folder id and a couple of default.mp3's. The createMusicList() function reads your Music Folder and Loads them into a sheet named 'MusicList' with columns of "Item", "File Name", "File Type" ,"File Id", and PlayList. The last column is just a column of unchecked checkboxes for you to make your current playlist selection. Only one playlist for now, so you can enjoy building your own.
Here's what the dialog looks like:
And here's an image of my MusicList Sheet:
This is where you make your playlist selections.
Audio Properties and Methods
Apps Script Documentation
Latest Script Code
I used the answer to this question as a starting point: playing sound with google script
You would need to open a html sidebar and use an audio tag, to do this you can use the HtmlService class [1].
As a total background you can't, the sidebar must be always open to play the music. But you could still play the audio while editing the document.
To add the audio setting you can add the controls attribute to the audio tag [2]. For playing the audio automatically you can add the autoplay attibute [3].
Here is the code I implemented to achieve your goal. The code gets the selected value and uses it to change the autoplay value to true and to display the audio as well. Also, when the select element is on focus, it gets the previous selected value so later (when a new value is selected) it can be used to stop the previous audio selection and not display it anymore. For these purposes I used the onchange [4] and the onfocus [5] events.

YUI3 Datatable loaded with JSON displays only no results to display (Scala/Play 2.1)

I am new to YUI but I veteran of JQuery UI. So this one has me stumped. I cannot get my Datatable to render with the Rest service. I have two version of the code. One that I use the captured JSON object from the service as just a data object and a local datasource. That one works fine. When I attempt to switch to the GET plugin and get it from the service. It just never renders.
My local example:

** edited because the original submission lost my second code block.
The problem wasn't with my javascript code. The issue was with how I was sending the response. The YUI framework expects that the response will be wrapped in a callback function. When I changed my response to give a JSONP response with the callback it all started working.
YUI.Env.DataSource.callbacks.yui_3_11_0_1_1379097239018_187([
{"script":{"id":34534,
"scriptText":"234523452345234",
"modifiedDate":1367525647000,
"status":"Reviewed",
"qcDate":1367526006000,
"location":{"id":1},
"orderInfo":{"id":1,
"orderName":"Order Name",
"dealerName":"Dealer Name"}
}},
{"script":{"id":656435,
"scriptText":"36536543636365",
"modifiedDate":1367525646000,
"status":"Reviewed",
"qcDate":1367526017000,
"location":{"id":1},
"orderInfo":{"id":43534534,
"orderName":"Order Name",
"dealerName":"Dealer Name"}
}}
])
I did this by using a JSONP call in the method response from Scala/Play 2.1
def reviewRecords(q: String, callback: String) = Action {
val reviewRecords = reviewRecordsService.currentReviewRecords
Ok(new Jsonp(callback, Json.toJson(DataTablesReturnObject(reviewRecords.size, reviewRecords.toArray)))).as("application/json")
}
I am going to edit the title of my original question to include the keywords for Play 2.1 and Scala because this ends up being a little different than a Java response.

How to open a new tab based on data taken from a FORM in "popup.html"?

I want to create a chrome extension which takes input from a "form" in popup.html and uses popup.js to open the website selected in a new tab.
**manifest.json**
{
"manifest_version": 2,
"name": "Question Searcher",
"description": "This extension displays the problem from popular online judges like UVA, SPOJ, Topcoder and Codeforces on serching the keyword. It also searches for a list of problems based on problem type.",
"version": "1.0",
"browser_action": {
"default_icon": "icon.png",
"default_popup": "popup.html"
},
"permissions": [
"tabs"
]
}
popup.html:
<!DOCTYPE html>
<html>
<head>
<script src = "popup.js" > </script>
<link rel = "stylesheet" type = "text/css" href = "theme.css" >
</head>
<body>
<h1> Search </h1>
<form name = "input">
<p>
Judge:
<select name = "judge">
<option value = "uva" selected> UVA </option>
<option value = "spoj" > SPOJ </option>
<option value = "tc" > Topcoder </option>
<option value = "tcat" > Topcoder Category </option>
<option value = "cf" > Codeforces Category </option>
</select>
<input type = "text" name = "keyword"<br>
<button type="button" onclick="return validate_register()">Go!</button>
</p>
</form>
</body>
</html>
**popup.js**
function validate_register()
{
alert("beep");
var str=document.forms["input"]["keyword"].value;
//alert(str);
switch(document.forms["input"]["judge"].value)
{
case "uva":
return chrome.tabs.create({url: 'http://www.uva.onlinejudge.org/external/'+str.substring(0,str.length-2)+'/'+str+'.html'});
break;
case "spoj":
return chrome.tabs.create({url: 'https://www.spoj.pl/problems/'+str.toUpperCase()+'/'});
break;
case "tc":
return chrome.tabs.create({url: 'http://www.topcoder.com/tc?module=ProblemArchive&class='+str});
break;
case "tcat":
return chrome.tabs.create({url: 'http://www.topcoder.com/tc?module=ProblemArchive&cat='+str});
break;
case "cf":
return chrome.tabs.create({url: 'http://www.codeforces.com/problemset/tags/'+str});
break;
}
}
This code is not working. I think the problem might be in the JS file, in chrome.tabs.create but i am not able to figure it out. Could someone point to the problem.
The problem is about Content Security Policy. When you're using manifest v2 for your chrome extension it doesn't allow to execute inline JavaScript in HTML code. (You can inspect popup with DevTools by right clicking on BrowserAction icon).
So that's why your onclick attribute isn't working. To fix this, you'll need to remove this attribute from HTML, and add code like this inside popup.js:
window.onload = function() {
document.querySelector('button').onclick = function(e) {
e.preventDefault();
validate_register();
};
};

Geolocation JSF

Does anyone have an example of sending a geolocation from a mobile phone to a JSF backing bean?
Would like to get the customers address using geolocation? (Will need to convert from geolocation co-ordinates to a drop down list of nearby roads).
Thanks,
D
Not sure if this will help u get started...
This pulls GPS Geolocation Data from Mobile Devices into a Form...
Then do whatever with it from there...
<script type="text/javascript">
function getLocationConstant()
{
if(navigator.geolocation)
{
navigator.geolocation.getCurrentPosition(onGeoSuccess,onGeoError);
} else {
alert("Your browser or device doesn't support Geolocation");
}
}
// If we have a successful location update
function onGeoSuccess(event)
{
document.getElementById("Latitude").value = event.coords.latitude;
document.getElementById("Longitude").value = event.coords.longitude;
}
// If something has gone wrong with the geolocation request
function onGeoError(event)
{
alert("Error code " + event.code + ". " + event.message);
}
</script>
<cfform action="gps2.cfm" method="post">
Latitude: <input type="text" id="Latitude" name="Latitude" value="">
<br><br>
Longitude: <input type="text" id="Longitude" name="Longitude" value="">
<br><br>
<input type="button" value="Get Location" onclick="getLocationConstant()"/>
<br><br>
<input type="submit" value="Add GPS Location" class=small>
</cfform>

JS:
// Note: This example requires that you consent to location sharing when
// prompted by your browser. If you see the error "The Geolocation service
// failed.", it means you probably did not give permission for the browser to
// locate you.
function initMap() {
var map = new google.maps.Map(document.getElementById('map'), {
center: {lat: -34.397, lng: 150.644},
zoom: 6
});
var infoWindow = new google.maps.InfoWindow({map: map});
// Try HTML5 geolocation.
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
var pos = {
lat: position.coords.latitude,
lng: position.coords.longitude
};
infoWindow.setPosition(pos);
infoWindow.setContent('Location found.');
map.setCenter(pos);
}, function() {
handleLocationError(true, infoWindow, map.getCenter());
});
} else {
// Browser doesn't support Geolocation
handleLocationError(false, infoWindow, map.getCenter());
}
}
function handleLocationError(browserHasGeolocation, infoWindow, pos) {
infoWindow.setPosition(pos);
infoWindow.setContent(browserHasGeolocation ?
'Error: The Geolocation service failed.' :
'Error: Your browser doesn\'t support geolocation.');
}
Using the Javascript you can get the co-ordinates and you can set the backend variable using document.getElementById("id")) in javascript.
Example:
<h:inputText value="{myBean.latitude}" id="latitudeID" />
<!DOCTYPE html>
<html>
<body>
<p>Click the button to get your coordinates.</p>
<button onclick="getLocation()">Try It</button>
<p id="demo"></p>
<script>
var x = document.getElementById("demo");
function getLocation() {
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(showPosition);
} else {
x.innerHTML = "Geolocation is not supported by this browser.";
}
}
function showPosition(position) {
x.innerHTML = "Latitude: " + position.coords.latitude +
"<br>Longitude: " + position.coords.longitude;
document.getElementById("formName:latitudeID").value=position.coords.latitude; /* this will set the value in variable */
}
</script>
</body>
</html>
