@3.2.0 can't call webkit.messageHandlers.cordova_iab.postMessage

[cowboy1967]

when I want to call webkit.messageHandlers.cordova_iab.postMessage on my webpage.htm, window.webkit is undefined, but it can work on @3.1.0 inappbrowser.....

so, I try to find reason, if I want to use post message, I have to do ... var ref=window.open ('http://xxxx/mypage.htm') // I must call this, so my page.htm can use webkit.messageHandlers.... ref.addEventListener('loadstone', function (){ ref.execJavaScript(';')});

You have to check below

1. Are you using wkwebview instead of uiwebview In my opinion, wkwebview can handle message but uiwebview isn't
2. At webpage javascript, use this code window.webkit.messageHandlers.cordova_iab_postMessage("message");

After I write 'window.webkit' instaed of just 'webkit', my code was worked

loadstone isn't a valid event, too.

@LouiMinister I am using the same code as you posted but receiving "TypeError: window.webkit.messageHandlers.cordova_iab_postMessage is not a function" on both iOS and Android. Previously this code used to work fine: "webkit.messageHandlers.cordova_iab.postMessage(message)", but with latest preferences set on wkwebview its not working. Do you have any solutions/workaround for this?

any updates here? iab.postMessage is undefined, executeScript also not working in iOS
