Subject [jira] [Commented] (CB-9445) executeScript callbacks not working for iOS
Date Thu, 19 Nov 2015 10:56:11 GMT


Sergey Grebnov commented on CB-9445:

Sounds good, will try this approach right now...

Will introduce `ensureCdvIframeBridge`, something like


    if (!_injectedIframeBridge) {
        _injectedIframeBridge = YES;
        // Create an iframe bridge in the new document to communicate with the CDVInAppBrowserViewController
        [self.inAppBrowserViewController.webView stringByEvaluatingJavaScriptFromString:@"(function
_ensureCdvIframeBridge(d){_cdvIframeBridge = document.getElementById('_cdvIframeBridge');
if(_cdvIframeBridge) return;var e = _cdvIframeBridge = d.createElement('iframe');'none';'_cdvIframeBridge';d.body.appendChild(e);})(document)"];




jsWrapper = [NSString stringWithFormat:@"_ensureCdvIframeBridge();_cdvIframeBridge.src='gap-iab%@://%@/'+encodeURIComponent(JSON.stringify([eval(%%@)]))",
command.callbackId, command.callbackId];

>          Components: Plugin InAppBrowser
>    Affects Versions: 5.1.1
>         Environment: Cordova 5.1.1 (CLI), ios 3.8.0, android 4.0.2, cordova-plugin-inappbrowser
1.0.1 (NPM)

> Can someone please check to see if they are encountering the same problem I am in the
environment I've listed? (latest released builds of everything I think)
> I open an inappbrowser window and then run an executeScript command using "code:" (not
"file:").  Everything works fine on Android, but on iOS, it simply will NOT fire the callback
function after executing the injected code.  Make the "code:" as simple as you like to test
it and see if you can get a callback to fire.  I've dumbed it down as much as possible and
can't get one to fire.  I know that all instances of code I've injected have run fine in the
iab by using the console (against the iab) to check for the variables I was creating in the
code.  I can't even get a callback to fire that doesn't expect a parameter to be passed back...
> Many thanks,
