system.hasDataCoverage no longer supported in BB10?

According to the WebWorks API docs, when we moved to BB10 we lost the blackberry.system.hasDataCoverage() function.  The console seems to confirm this:


Uncaught TypeError: Object [object Object] has no method 'hasDataCoverage'


Is there a BB10 alternative to checking for coverage before issuing a request?

Re: system.hasDataCoverage no longer supported in BB10?

There is an HTML5 standard for this, so a platform-specific API is no longer required:



if (navigator.onLine) {
} else {


Background: hasDataCoverage() originated on the BlackBerry 5.0 OS, before the days of HTML5

Thank you for the information.  Have you seen this work in the Ripple Emulator?  I tried setting my connection type to NONE in the "Device & Network Settings" area and the onLine property still returns true...


Perhaps the property is unaware of the Ripple configuration and is reporting the status of Chrome's internet connection.
