Re: JsInterop Question regarding execution in index.html

Thanks that worked! Given that this flag was off by default,  what are the main ramifications of leaving it on?

.....

The below code is successfully exported globally when the flag is on:

@JsMethod(namespace = JsPackage.GLOBAL, name = "handleOpenUrl")

public static void runMe(String url) {

  Window.alert("Success");

}

Thanks for the quick reply.  This was my first inclination, which does not work.

@JsMethod(namespace = JsPackage.GLOBAL, name = "handleOpenUrl")

public void runMe(String url) {

    Window.alert("Success");

}

Perhaps, I am doing it wrong, but I had always thought the JsInterop wraps existing javascript. I am trying to declare a new javascript function in the global namespace so that a cordova plugin can call it.  handleOpenUrl does NOT exist, but I am responsible for creating it.

Below js code does work inside my index.html.  I need to emulate that is GWT.

function handleOpenURL(url) {

     alert("received url: " + url);

}

You can use jsinterop.

I need to create a javascript function called "handleOpenUrl(url)" that will be called from a Cordova plugin (https://github.com/EddyVerbruggen/Custom-URL-scheme)  for a hand off from a mobile browser.  If I create the function inside my index.html, it is called successfully. The challenge is how do I move the execution into my GWT module?  

My ideas are...

1:  Somehow create a GWT method that is recognized in the global js namespace as "handleOpenUrl"?  I know method names get compiled out, so I am not sure how I would accomplish this.  

2.  Leave the handleOpenUrl inside the index.html, but somehow call a GWT method from that?

Any thoughts/ideas would be much appreciated.
