Set Applet PARAM VALUE from javascript |
|
|
PARAM VALUE can't be changed ar run-time but during layout time, javascript "entities" can be used to set calculated VALUES.
In this How-to, VALUES are coming from a javascript variable, a javascript function and a javascript expression.
<HTML><HEAD></HEAD><BODY>
<SCRIPT>
var jsVar = "Hello World from jsVar";
function jsFnct() {
return "Hello World from jsFnct";
}
</SCRIPT></HEAD><BODY>
<<APPLET CODE ="MyApplet.class" HEIGHT=100 WIDTH=400>
<PARAM NAME="first" VALUE="&{jsVar};">
<param name="second" value="&{jsFnct()};">
<param name="third" value="&{'hello world'.toUpperCase() + ' from js Expression'};">
</APPLET>
</BODY></HTML>
|
For demonstration purpose, the MyApplet class:
import java.applet.*;
import java.awt.*;
public class MyApplet extends Applet {
public void init() {
add(new Label(getParameter("first")));
add(new Label(getParameter("second")));
add(new Label(getParameter("third")));
}
}
