Hi,

I have a table which I'm trying to do a pricing list, that auto-computes the tax component..

I'm getting the value from price_1, applying a math cal, and saving it to tax_1. I could read the number of the end of the id, but hopefully there is a cleaner way with jQuery.

E.g. I would have a lot of fields like..

• price_1
• price_2
• price_3
• tax_1
• tax_2
• tax_3 etc...

I can use the following code to call jQuery on change of a price, and get the value of that price. How do I update the tax field next to it? should I use a sibling selector or something??

$('#pricing').delegate("input", "change", function(){

  $(this).val() /* the value of the price */; 

})
