Something's wrong with the display of my app when I tried to build it in cordova. Here's the code:
<html>
<head>
<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; media-src *">
<meta name="format-detection" content="telephone=no">
<meta name="msapplication-tap-highlight" content="no">
<meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width">
<link rel="stylesheet" type="text/css" href="css/index.css">
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.css" />
<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
<script src="http://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js"></script>
<title>Swaggity swag swag</title>
</head>
<body>
<form action="res/link2.html">
<input type="text" placeholder="Name" name="name">
<input type="text" placeholder="Text" name="comment">
<button type="submit">Leggo!</button>
</form>
<script type="text/javascript" src="cordova.js"></script>
<script type="text/javascript" src="js/index.js"></script>
</body>
</html>
When I built it, text field displayed ended up displaying like this:

I hope you can help me out on this one, thanks!
I put your code in a fresh cordova application (CLI Version 5.1.1; Visual Studio 2015) and got some security errors in the output console, because you are referencing to http://code.jquery.com. Anyway your provided screenshot looks like, the styles loaded somehow, but giving strange results.
In my case I got the folowing errors in the JavaScript Console in Visual Studio:
Refused to load the stylesheet 'http://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.css' because it violates the following Content Security Policy directive: "style-src 'self' 'unsafe-inline'".
index.html (15,0)
Refused to load the script 'http://code.jquery.com/jquery-1.11.1.min.js' because it violates the following Content Security Policy directive: "default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'". Note that 'script-src' was not explicitly set, so 'default-src' is used as a fallback.
index.html (0,0)
Refused to load the script 'http://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js' because it violates the following Content Security Policy directive: "default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'". Note that 'script-src' was not explicitly set, so 'default-src' is used as a fallback.
index.html (0,0)
To avoid these errors, I changed the meta tag for Content-Security-Policy and added http://code.jquery.com:
<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com http://code.jquery.com; style-src 'self' 'unsafe-inline' http://code.jquery.com; media-src *">
With these changes all looks fine in ripple:
The above solution won't work directly on the platforms iOS, Windows 8.1/10 and Android because of security policies.
There are two solutions I think:
I would recommend to download the scripts and style sheets and access them localy under the www folder.
Another way is to allow access to external resources. For that you need the whitelist plugin:
https://github.com/apache/cordova-plugin-whitelist
... and you have to edit the config.xml under Common->Domain Access->URI and add http://code.jquery.com
This will produce an XML entry in this file:
<!-- Allow images, xhrs, etc. to http://code.jquery.com -->
<access origin="http://code.jquery.com" />
After that all looks fine under Windows 10 for example:
Hope that helps!

Please could I ask for help with the following:
I have cloned the Electron starter app like so:
git clone https://github.com/electron/electron-quick-start
And have it running.
I have added one line:
<button id="doitButton" onclick="alert('t')">DoIt</button>
Here it is in the context of the main.js file:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<!-- https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP -->
<meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'">
<link href="./styles.css" rel="stylesheet">
<title>Hello World!</title>
</head>
<body>
<h1>Hello World!</h1>
<button id="doitButton" onclick="alert('t')">DoIt</button>
We are using Node.js <span id="node-version"></span>,
Chromium <span id="chrome-version"></span>,
and Electron <span id="electron-version"></span>.
<!-- You can also require other files to run in this process -->
<script src="./renderer.js"></script>
</body>
</html>
I am working in VSCode. I am sure to save the file and then I run "npm start".
I see the button, but no alert when I click it. What have I done wrong?
Thanks for any help.
I have found a solution.
If I comment out the line:
<meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'">
Then I see the alert appearing.
I am trying to load in the necessary libraries from firebase into an electron project, currently the header looks like this:

<meta http-equiv="X-Content-Security-Policy" content="default-src 'self'; script-src 'self'">

However, when I try and run and test if they're working, I get the following error messages:
I'm quite new to Electron, JavaScript, and Firebase, so I'm not sure where I'm going wrong here. Thank you in advance for your help.
You have two content-security-policy meta tags. Initially you should remove one of them unless you have some specific reason for having a duplicate content-security-policy, as any content must pass all CSPs. Then you need to add www.gstatic.com into the script-src directive.
Also watch out for content-security-policy inserted as a response header as some frameworks may insert CSP as a header. You may also want to move your meta tag to response headers as meta tags don't support all directives of CSP.
When I upload an image into my web application, it is showing the below error
Refused to load the image ' <URL> because it violates the following Content Security Policy directive: "default-src * data: 'unsafe-eval' 'unsafe-inline'". Note that 'img-src' was not explicitly set, so 'default-src' is used as a fallback.
I try to solve this error by using the following code
<meta http-equiv="Content-Security-Policy" content="default-src *; img-src * 'self' data: https:; script-src 'self' 'unsafe-inline' 'unsafe-eval' *; style-src 'self' 'unsafe-inline' *">
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
But it is not working. How can I fix this problem?
I am not sure why you are using an "*". I am using a similar kind of stuff, but my meta tag looks something like this and it works fine for me:
<meta http-equiv="Content-Security-Policy" content="default-src 'none'; connect-src 'self';font-src 'self'; img-src 'self' data: https:; style-src 'self' ; script-src 'self'">
I created a cordova project, added the iOS platform and built the project. After that I opened the .xcodeproj in Xcode, built it and the homepage showed the sample app homescreen. I then created another js file with the following content in the Staging/js folder
function testLoad(){
alert("Loaded!");
}
In index.html, I added
<script type="text/javascript" src="js/myScript.js"></script>
and called the function
<body onload="testLoad()">
However no alert appears! How to fix? I am using xCode 7.2.1 and Cordova 5.4.1.
The issue is due to the Content Security Policy set in index.html. As told on https://issues.apache.org/jira/browse/CB-10598, the tag should be set to
<meta http-equiv="Content-Security-Policy" content="default-src 'unsafe-inline' 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; media-src *">
If your js is in Staging/js, then your script should be
<script type="text/javascript" src="Staging/js/myScript.js"></script>
Anyway, you can debug with safari to look for errors, check this.
https://developer.apple.com/safari/tools/
I have run your project and found error. After solving error, I can able get alert.
Please chage your below code
<script type="text/javascript" src="Staging/js/myScipt.js"></script>
with
<script type="text/javascript" src="js/myScript.js"></script>
And if still error/problem is there, let me know.
I am building an app with Meteor for a couple of weeks now, without any problems. Yesterday I didn't had any problems either.
Today I wanted to continue building my app, and the terminal gives me this error every 10 seconds:
I20151208-11:19:04.463(1) (android:file:///android_asset/www/plugins/cordova-plugin-whitelist/whitelist.js:25) No Content-Security-Policy meta tag found. Please add one when using the cordova-plugin-whitelist plugin.
So I tried running another Meteor project, and got the same error.
I have googled this error, and it says I have to change the config.xml in my project. I dont know where config.xml is located in a Meteor project, but since the error is showing to ALL projects I'm trying to run, I dont think that's the solution.
Can anyone help me solve this problem?
EDIT:
I added this line in the <head> tag of my Meteor project, and in the <head> tag of my .meteor/local/cordova-build/www/index.html file:
<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; media-src *">
Also, I added this to my .meteor/local/cordova-build/config.xml:
<allow-navigation href="*" />
And this to my mobile-config.js file:
App.accessRule('*');
Without success :(
Please add this code to your index.html header
<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; media-src *">
Solved! Restarted my phone, and that solved the problem!
