Hello,all,

>From NS javascript tutorial  :

Example n°4

<HTML>
<HEAD>
<SCRIPT LANGUAGE="JavaScript">
  function compute(form)
  {
    if (confirm("Are you sure?"))
      form.result.value = eval(form.expr.value)
    else alert("Please come back again.") }
</SCRIPT>

</HEAD>
<BODY>
 <FORM>
Enter an expression:
<INPUT TYPE="text" NAME="expr" SIZE=15 >
<INPUT TYPE="button" VALUE="Calculate" ONCLICK="compute(this.form)"> <BR>
 Result:
<INPUT TYPE="text" NAME="result" SIZE=15 > <BR>
</FORM>
</BODY>
</HTML>

When you send the value on a form to a function from INSIDE the form you use:

Eventhandler="CalledFunction(this.form)"

How is this done when the sended form is another form that is NOT this.form
in this example, instead of

<FORM>
Enter an expression: <INPUT TYPE="text" NAME="expr" SIZE=15 >
<INPUT TYPE="button" VALUE="Calculate" ONCLICK="compute(this.form)"> <BR>
 Result: <INPUT TYPE="text" NAME="result" SIZE=15 > <BR>
</FORM>

if we had :

first form
<FORM>
Enter an expression: <INPUT TYPE="text" NAME="expr" SIZE=15 >
</form>

..
second form
<form>
<INPUT TYPE="button" VALUE="Calculate" ONCLICK="compute(how.is.the.form.sent)">
</form>                                                 ^^^^^^^^^^^^^^^^^^^^^^
..

third form
<form>
 Result: <INPUT TYPE="text" NAME="result" SIZE=15 > <BR>
</FORM>

the goal is to say to the second form :
                          ^^^^^^^^^^^^
'hey ! when the user whose name is in the first form click on this button, send the
                                          ^^^^^^^^^^^         ^^^^^^^^^^^^
result to the third form (the third form beeing in the same window or in a
              ^^^^^^^^^^
javascript-created other window).
