goBack not working?

[paul3252]

I have searched the forum and their is not too much regarding the navigation controller goBack function. I thought the below code would take me back to the page 'calling' the page on which this internet check occurs. It does not however do that. The page stops, remains blank but does not return to the calling page.

Any suggestions?

Code: Select all

<script type="text/javascript">
            
            var navController = new NKNavigationController();
            navController.setTitle("News Feed");
            navController.setTintColor(0,62,128);
                        
            function onPageShown(caller)
            {
            
            if (NKIsInternetAvailableViaWifi() != "1" && NKIsInternetAvailableViaCellularNetwork() != "1")
            {
                
                NKAlert("Error", "Internet Connection is required");
                navController.goBack();
                
            }
            }
             </script>

This code alone seems ok, but we don´t know if you have more code on that page that could crate a javascript error for instance. Use try /catch and NKLog to check what is happening under the hood

Have you a navigation controller on the parent page. You needs it

Thanks both for looking, I have made no changes to the code, but it is now working, so I can only assume that Xcode was having an off day when I posted.
