How To Send Javascript Variables To Java Applet

I have a JavaScript function which is: function printreceipt(tax,subtotal,total) { subtotalElem=document.getElementById('total'); var taxElem=document.getElementById('tax'); produc

Solution 1:

Your applet should have a public method , for example receiveData() :

publicvoidreceiveData(String dataFromJS)
{
   //Do what you need with your data
}

Let's say you have something like that in your web page :

<applet id ="appletID" name="myApplet" ... ></applet>

In your javascript you just have to call the applet public method like this :

var myApp = document.applets['myApplet'];
myApp.receiveData(taxElem.innerHTML + subtotalElem.innerHTML);

The previous example will send the taxElem and subtotalElem content to the applet.

To send data from Applet to JS you sould use JSObject in your applet

Solution 2:

You can use netscape.javascript.JSObject for Java-to-JS direction or reference the applet by its id for JS-to-Java.

See here for detailed example : http://rostislav-matl.blogspot.com/2011/10/java-applets-building-with-maven.html

Solution 3:

The most reliable way to do this is to open a new page with the parameters encoded in the URL, then write those parameters as into an applet element as param elements. (Though +1 to each of the other answers.)
