Angular/Ionic not updating an image src when ng-src is empty

The Angular ngSrc directive serves to properly set an image src via Angular. As anything in Angular, it updates the image as soon as the contained Angular expression changes. However, when the ng-src attribute is empty, Angular will not empty the src attribute. To overcome this, use the trick below.

<img ng-src="{{ element.image || '//:0' }}" />

Background

The ngSrc directive explicitly returns when the attribute value is false. As a workaround, set a "blank" image src when the image is empty. As somebody on Stackoverflow writes, //:0 serves this purpose: It adopts the current protocol, omits the hostname and sets the port to zero, which is invalid and should be killed by the network layer.

As a result, Angular should now correctly empty the src attribute when ng-src empties.

Self Signed SSL Certificates in PhoneGap

Code to allow self signed certs on PhoneGap 

Android:

• If you are doing development: android:debuggable="true" in the manifest, you should allow the browser to request data from servers with a self-signed or bad SSL cert 
• If you are releasing an application, you should remove the android:debuggable="true" (Android Market won't let you release with this on anyway) and you will NOT be able to send data to a server with a bad SSL cert 
• If you don't have this flag set, the default will be what the default is now, which is that you won't be able to send data to servers with a self-signed cert 

iOS: 

Just Add below code at the end of you AppDelegate.m file

@implementation NSURLRequest(DataController)
+ (BOOL)allowsAnyHTTPSCertificateForHost:(NSString *)host
{
    return YES; 
}
@end
