Hello,

My app has an order. This order has products, which is chosen in a  
select list.

each product is added by a partial like this:

1. 
2. 
3. product1
4. 
5. 
6. 
7. 
8. 

“Onchange” a product, the price is updated via ajax using rjs. thats  
OK.  
but, when I add another product, it update the first product price, of  
course, because it have the same name and ID. But I can not change  
this, so is there some way to get the next input element via  
javascript? Selecting the next input element or something like this.

thnks a lot!!!

Have a look at jQuery, it’s great for stuff like this.
