Hi,  
I have a huge table in database and need to fill the values using web  
forms.  
Some fields are repeatable so my form can have a link to provide same  
form many times.  
I can acheive this by using java script but how to get id of elements  
added dynamically.  
For example if I add one

 containing 1 text box 1 combobox, how  
to get ids so that I can use them in my erb file.
