[Proto-Scripty] evalScripts

[bill]

The script that loads the div is:

function scriptChain (evt, newDivID, chainToProgram, chainFromFormID) { 
// scriptChain
//alert (scriptChain:  + newDivID +  - + chainToProgram +  with 
+ chainFromFormID +);

stopBubble (evt);
// if chainFromFormID is blank, use a chain without data
if (chainFromFormID == )   { // no data
//alert (with no data);
closeMenu2 () ;  // no harm if it does not need to be closede
document.getElementById (newDivID).style.display = block;
new Ajax.Updater(newDivID, chainToProgram, {
evalScripts:true
});
return false; //inhibit the href
} //no data
else   { // with data
new Ajax.Updater(newDivID, chainToProgram, {
parameters:  $(chainFromFormID).serialize(true),
onFailure: function(response) {
alert (patient.php: failure to submit form:  + 
chainFromFormID);

},
evalScripts:true
});
return false;
} //with data
} // scriptChain
---
and works fine
The page that I am loading has as a fragment:
--
SCRIPT type=text/javascript

window.reformat = function (t,d) {
   var bal  = ( Math.round((t.value * 100) + .4))/100.0;
t.value= FormatNumber(bal,2)
return true
}

window.recalc = function (t,d){
reformat(t,d);
//then recalc amount remaining
var bal = t.form.amount.value
bal -=t.form.amount1.value
bal -=t.form.amount2.value
bal -=t.form.amount3.value
bal -=t.form.amount4.value
bal -=t.form.amount5.value
bal -=t.form.amount6.value

t.form.amount_remaining.value = bal
reformat(t.form.amount_remaining,2)
if (t.form.amount_remaining.value 0.0) { // error
alert (ERROR, you can not distribute MORE than the amount of 
the payment)

}
 }
/script

but when I call recalc, I get the error message: recalc is not defined.

thoughts/suggestions please
where did I go wrong ?

These are old scripts that I am using in the rewrite of an application, 
but should work.

[Proto-Scripty] evalScripts and functions

[Michael]

I understand how Prototype works with regards to the removal of
script tags after evaling the results of an Ajax request.  However,
I was doing some research and am now starting to wonder why the way I
declare functions works.

According to the Prototype documentation, you need to declare the
function and assign it to a global variable:

myFunction = function() {alert('hi');}

That makes sense.  However, in all of my scenarios, I've declared
functions like this:

var myFunction = function myFunction() {alert('hi');}

and the calls to myFunction work just fine.  My question is...why does
my way work?  According to the Prototype documentation, the local
variable myFunction should be thrown away after the eval.  Any insight
anyone can provide would be appreciated.  Thanks in advance!

[Proto-Scripty] evalScripts problem

[Ehsun]

I've create an Object in my pages script tags, something like this:

a = new A();

and when I want to call a method of a in the script which is actually
the ajax content (evaluated with .evalScripts) everything is fine. but
when the creation and the calling code, both are in the ajax contents
(seperate requests) which are evaluated! the second script (calling
script) has no access to the object!!!

What should I do?
