Hi ,

I am new to javascript and have coded an invoice page through help from some available

content on web.

here is my requirement

My form contains inputs "item ,rate quantity,price" in a tabular form where one can

dynamically add or delete rows.And the requirement is that

when Quantity is entered the Price should change to Price=Quantity*Rate on tab out

So I have used a Javascript onchange() and this works fine for the first displayed row.

but for dynamically added rows this does not happen, I am not able change the price

value for dynamically added rows.

Code is as below
direct_invoice.html



my java script for dynamically adding rows works as below for each cell

for newly added row the columnQuantit will be created like this

Add row()




calculate price:
