Further to my previous post, I have uploaded the code as a JSFiddle.1. Default view of list of usersA full list of all users in the "Users" table is retrieved and displayed. "Edit" and "Delete" buttons appear alongside each entry.2. Edit an existing user entryThe default text that appears when you edit an existing entry depends on your implementation of copyBackingFields(). In this case, both fields are populated with the record's existing data.3. Add a new userOn clicking "New user", a new record ......
Envisage almost any data-driven user interface, and sooner or later you will probably come across a requirement like: - present the user with a list (of users, addresses, products, etc.) - allow the user to edit or delete an existing item in the list - allow the user to create a new item and add it to the listI decided to have a look at several web-based technologies to see how easy it might be to fulfil this requirement in as generic and extensible a way as possible, with the absolute minimal in ......
If you google carefully, it appears there are some resources to help with a common problem.But just for good measure, here's my own implementation, which utilises the fact sq(n) = (n-1)(n+1)+1, and the difference between two terms "t" apart in the resultant series is 2t + 3. Theoretically this should give you the square root in a single iteration, once the nearest power of two has been calculated, an initial step which I'm sure can be optimised. But because all operations are integer-based, in practice ......
