如何以类似的方式从javascript调用android和iOS swift中的函数

Question

I am trying to call functions in android and iOS Swift (WKWebview)from javascript .

For Android:

public class WebAppInterface {

    WebAppInterface(Context c) {
        mContext = c;
    }

    @JavascriptInterface
    public void postMessage(String message) {
        Log.v(TAG, "message ----"+message);
        Toast.makeText(mContext, message, Toast.LENGTH_SHORT).show();

    }
}

webView.addJavascriptInterface(new WebAppInterface(mContext), "appInterface");

JavaScript call For Android:

window.appInterface.postMessage("Hello);

Javascript call for iOS:

window.webkit.messageHandlers.appInterafce.postMeesage("Hello");

So, here we are making different calls from javascript for android and iOS . Is it possible to call functions in both android and iOS in one single way?

Thanks.

Wrap them both up in a single function?

function postAppMessage(msg) {
    if (window.webkit != undefined) {
        if (window.webkit.messageHandlers.appInterface != undefined) {
            window.webkit.messageHandlers.appInterface.postMessage(msg)
        }
    }
    if (window.appInterface != undefined) {
        window.appInterface.postMessage(msg)
    }
}
