---------------------------------
Summary: The deviceReady event may not be received because of
asynchronous JavaScript loading
Key: CB-2166
URL: https://issues.apache.org/jira/browse/CB-2166
Project: Apache Cordova
Issue Type: Bug
Components: CordovaJS, Docs
Affects Versions: 2.2.0
Environment: Cordova 2.2, Android 2.3.4
Reporter: Thomas Dinger
Assignee: Filip Maj
HTML page includes Cordova script first, then my Cordova-dependent script. My
script registers a listener for the deviceReady event. Occasionally the
listener is not called. I've determined the problem is due to the timing of the
asynchronous loading of the script files. Because of the way cordova "hijacks"
the document.addEventListener function, my event handler may be registered with
the document object instead of Cordova, depending on whether the Cordova script
is executed before my script.
Would it be possible for Cordova to look at the document object and determine
whether there are existing event listeners for the deviceReady event? And if
there are, to "hijack" these event handlers so they are called correctly when
Cordova sends the deviceReady event?
I have changed my code to wait for the DOMContentLoaded event before
registering my deviceReady event handler. This has been successful for me, and
might be an approach that could be used in the Cordova documentation.
