As far as i know, using BrowserFunction() to register function is gone in new versions of jxbrowser. There is a new way in 6.1 version described here. Putting the new way in your code :
import com.teamdev.jxbrowser.chromium.Browser;
import com.teamdev.jxbrowser.chromium.BrowserFunction;
import com.teamdev.jxbrowser.chromium.JSValue;
import com.teamdev.jxbrowser.chromium.LoggerProvider;
import com.teamdev.jxbrowser.chromium.swing.BrowserView;
import javax.swing.*;
import java.awt.*;
import java.util.logging.Level;
import java.util.logging.Logger;
public class JavaScriptJavaSample {
public static void main(String[] args) {
LoggerProvider.setLevel(Level.OFF);
Browser browser = new Browser();
BrowserView browserView = new BrowserView(browser);
browser.addLoadListener(new LoadAdapter() {
@Override
public void onFinishLoadingFrame(FinishLoadingEvent event) {
if (event.isMainFrame()) {
Browser browser = event.getBrowser();
JSValue value = browser.executeJavaScriptAndReturnValue("window");
value.asObject().setProperty("java", new Events());
}
}
});
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
frame.add(browserView, BorderLayout.CENTER);
frame.setSize(700, 500);
frame.setLocationRelativeTo(null);
frame.setVisible(true);
browser.loadHTML("<html><body><a href='#' onclick='alert(java.MyFunction());return false;'>Call Java method</a></body></html>");
}
}
Create another file to hold Events class :
public class Events {
public String MyFunction() {
System.out.println("MyFunction is invoked!");
return new String("Hello");
}
}
* Added return false to the end of onclick attribute of a tag, preventing browser from following the link href on click.
BTW, I suggest you to use main documentation codes, as they are up-to-date.
