John Little created CB-8661:
-------------------------------
Summary: executeScript doesn't return the a result on Windows
platform
Key: CB-8661
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.
