Java/jsp Learning Series 14th (JavaScript changes applet status)

The following example shows how to use JavaScript to change the applet status and call the method in the applet in Javascript.

1. Applet source code (tmin_js2.java)

// Import
Import java. AWT. graphics;
Import java. AWT. event;

// Liveconnect... for Javascript
// Not used... (it's more simple)

Public class tmin_js2 extends java. Applet. Applet {
// Variables
String STR; // sample string...
Int I; // Nb change...

// Initialisation de l' Applet
Public void Init () {// methode Init ()
STR = new string ("test ");
I = 0;
}

// Dessiner l' Applet
Public void paint (Graphics g) {// methode paint ()
G. drawstring (STR, 5, 10 );
}

// Setstring: change string value
Public void setstring (string s ){
STR = new string (s );
I ++;

// Force repaint to see change
Repaint ();
Return;
}

// Getstring: Get string value
Public String getstring (){
Return STR;
}

// Getval: get number of change
Public int getval (){
Return I;
}

}

Ii. Notes

(1) In the applet, name it:

<APPLET codebase = "./" code = tmin_js2 width = 80 Height = 25 name = test1>
