Re: How To Catch Network Disconnection In Ajax Buttons

Hi,

You can use browser's online and offline events to be notified when
the network is down for some reason. See

 Hi,

 How do we catch network disconnection ?

 For example, I'm submitting using an indicatingajaxbutton, when the
 network is disconnected, the loading indicator disappears and the
 button is available again. Is there anyway that I can catch network
 disconnections in indicatingajaxbutton or any ajax button for that
 matter.

 I would like to post an alert warning to the client that he/she has
 been disconnected from the server.

 Is there anyway that I could insert something into this method?

 this is in wicket-ajax.js

 failure: function(message) {
        if (message != null)
            Wicket.Log.error(Wicket.Ajax.Call.failure: Error while
 parsing response:  + message);
        this.request.done();
        this.failureHandler();
           Wicket.Ajax.invokePostCallHandlers();
           Wicket.Ajax.invokeFailureHandlers();

You can register 'postCallHandler' and/or 'failureHandler' and this
method will call it/them for you.

    }

 Thanks!
 Carlo
