Hello,  
how can i get the values of a form that has been filled out but was not  
sent to the database.  
i have a collection\_select formfield and i need the selected item to  
fill an DIV with content specific to the selected item.

In Javascritp i´ve done it in this way:

for (i = 0; i \< document.formular.zeitung.length; ++i)  
if (document.formular.zeitung.options[i].selected == true){  
var textinhalt = document.formular.zeitung.options[i].value;  
}

So in textinhalt the value is stored. How can i achieve this with ruby?
