Pier Bover created CB-11885: ------------------------------- Summary: iframe message error Key: CB-11885 URL: https://issues.apache.org/jira/browse/CB-11885 Project: Apache Cordova Issue Type: Bug Components: Plugin WKWebViewEngine Affects Versions: 4.2.1 Environment: iOS 9 Reporter: Pier Bover Assignee: Shazron Abdullah
When trying to communicate between an iframe and the main window using Window.postMessage() I get the error: `Blocked a frame with origin "null" from accessing a frame with origin "null".` This only happens from the iframe to the main window, when communicating the other way around it works fine. Both files are run locally. The error only happens after adding the plugin `cordova-plugin-wkwebview-engine`. When using UIWebView the error does not happen. The weird thing is that this error is shown exactly 11 times, but the message goes through anyway. See this screenshot taken from Safari while using the simulator: http://i.imgur.com/JJkIEy5.jpg You can the Messageevent happening at the end. I have added `sandbox="allow-same-origin allow-scripts allow-popups allow-forms"` to the iframe tag and it fix it. This is the code that listens to the message: `window.addEventListener("message", eventHandler, false);` And this is the code that emits the message from the iframe: `parent.postMessage(something,"*")` -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@cordova.apache.org For additional commands, e-mail: issues-h...@cordova.apache.org
