Access applet variable from HTML page

[Rodie]

Hi

I created a java applet that is loaded in a HTML page containing Javascript (to interact with the applet).

I would like to initialize the variables of my applet and use the <PARAM> tag to customize the applet variables from the side of the HTML page.

For example : on the java class

public class Test extends Applet {
public int var;
}

in HTML page :

<APPLET name="Test" width="1" height="1" code="Test.class" codebase="." mayscript="mayscript">
<PARAM name="var" value="js_var">
</APPLET>
<SCRIPT LANGUAGE="javascript">
document.Test.js_var = 3;
</SCRIPT>

But this does not work .. thanks if you know how to do

This link explains how to pass parameters to your applet :

What you are trying to do will fail for two reasons :

1) The javascript block is executed after the applet tag.
2) "js_var" is a value - not a tag name or id. If it were to work, it would be like accessing a form I guess - eg : "document.Test.var.value = 3" - but this does not work either. Not sure how you would get it to work. Probably easier to do with server-side scripting.

You are right : js_var is a value!
I finally do something like this :

public class Test extends Applet {
public int var = getParameter("js_var");
}

<APPLET ...>
<PARAM name="var" value="49.56.21.255">
</APPLET>

Thanks to you !
