Question

I added another JS file to my project : test.js

and I have the code in test.js:

var testObj = {
  hello : function(){
    alert("hello world");
  }
}

and I added this line to the main HTML file in my project:

the script is under the same folder as HTML file.

In the Java code, I call this function by:

public static native void helloWorld()/*-{
    testObj.hello();
}-*/;

But when I run it, it tells me testObj is undefined. But in the browser console, when I do: testObj.hello() and it is working (so the JS file is loaded).

How can I make it work?

Answer 1

Solved by myself.

change the call to:

public static native void helloWorld()/*-{
    $wnd.testObj.hello();
}-*/;

$wnd must be $wnd, window, document, this or $doc will not work.
