Thanks for theses interesting examples, though it seems that
- as far as I understand it - these are not classes that are
guaranteed to be part of Java SE.
Not very clear.
The documentation is here:
http://docs.oracle.com/javase/7/docs/jre/api/plugin/dom/index.html
http://docs.oracle.com/javase/tutorial/deployment/applet/invokingJavaScriptFromApplet.html
http://www.oracle.com/technetwork/java/javase/plugin2-142482.html
In:
http://docs.oracle.com/javase/7/docs/
it is in JRE but not in SE API.
I would interpret it as that it is supported with Oracle Java,
but no guarantee for IBM Java etc..
Looking at my own link, then it looks as if the NewStyle should
be done as:
package htmldemo;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
import javax.swing.JApplet;
import org.w3c.dom.html.HTMLDocument;
import org.w3c.dom.html.HTMLInputElement;
public class NewStyle extends JApplet {
public void calc() {
try {
Class<?> c = Class.forName("com.sun.java.browser.plugin2.DOM");
Method m = c.getMethod("getDocument", new Class[] {
java.applet.Applet.class });
HTMLDocument doc = (HTMLDocument)m.invoke(null, new Object[] { this });
HTMLInputElement myfield1 =
(HTMLInputElement)doc.getElementById("myfield1");
HTMLInputElement myfield2 =
(HTMLInputElement)doc.getElementById("myfield2");
HTMLInputElement myfield3 =
(HTMLInputElement)doc.getElementById("myfield3");
int val1 = Integer.parseInt(myfield1.getValue());
int val2 = Integer.parseInt(myfield2.getValue());
int val3 = val1 + val2;
myfield3.setValue(Integer.toString(val3));
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (NoSuchMethodException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
}
}
