>                 URL: https://issues.apache.org/jira/browse/CB-8661
>             Project: Apache Cordova
>          Issue Type: Bug
>          Components: Plugin InAppBrowser, Windows
>         Environment: Windows 8
> Latest version of Cordova 4.3.0
> Latest version of Plugin InAppBrowser 0.6.0
>            Reporter: John Little

> executeScript is supposed to provide a variable to the function called when the script
is completed as per this clip from the documentation :-
> If the injected script is of type code, the callback executes with a single parameter,
which is the return value of the script, wrapped in an Array. For multi-line scripts, this
is the return value of the last statement, or the last expression evaluated.
> When running as a Windows app the array is empty.
> Looking in the Windows InAppBrowserProxy.js file, line 230 looks like this
>    op.oncomplete = function () { hasCallback && win([]); };
> So clearly no data is being passed ([]) is an empty array.
> According to the documentation from Microsoft :-
> https://msdn.microsoft.com/en-us/library/windows.ui.xaml.controls.webview.invokescriptasync.aspx
> The invokeScriptAsync function can return a string.
> So if I modify line 230 to look like this
>   op.oncomplete = function (e) { hasCallback && win([e.target.result]); };
> I get a string returned to my callback function.
> You could also modify the similar line in the injectScriptFile function, as it also calls
invokeScriptAsync.
> I need the return value because the only way to comunicate between the page in the IAB
and the app is to poll some sessionStorage and wait for the page to set some data.
