Subject: JavaScript vs Java Date - msg#00147

Hello,

I have this test program which I exepcted to return true. I construct a Java date to be 10/30/2004 and an equivalent JS date. However, when I compare them by calling getTime(), the result is always false.

Thanks for any pointers.

import java.util.Date;

import org.mozilla.javascript.Context;
import org.mozilla.javascript.Function;
import org.mozilla.javascript.Scriptable;
import org.mozilla.javascript.ScriptableObject;
import org.mozilla.javascript.WrapFactory;

public class JavaDate {
public void runJavaScriptTest(int n) {
Context cx = Context.enter();
try { ScriptableObject scope = cx.initStandardObjects();
cx.setWrapFactory(new MyWrapFactory());
String s = "function foo(javaConvertedDate) {return new Date(2004, 10, 30).getTime() == javaConvertedDate.getTime()} ";
Function f = cx.compileFunction(scope, s, "<cmd>", 1, null);
Object args[] = {new Date("10/30/2004")}; Object rc = f.call(cx, scope, f, args); <================================= It is always false.
System.out.println("Test1 Call result " + rc + " :" +
rc.getClass());

} catch (Exception e) {
e.printStackTrace();
}
finally {
// Exit from the context.
Context.exit();
} }

public Scriptable wrapAsJavaObject(Context cx,
Scriptable scope,
java.lang.Object javaObject,

if (javaObject instanceof java.util.Date) {
long time=((java.util.Date) javaObject).getTime();
return cx.newObject(scope, "Date", new Object[] { new
Double(time) });
} return super.wrapAsJavaObject(cx, scope, javaObject, staticType); }
}

public static void main(String[] args) {
JavaDate myTest = new JavaDate();
myTest.runJavaScriptTest(1);
}
