Validating form using ajax professional dating buffalo ny
Image maps only work if the images are contiguous in the page, such as a navigation bar.
Defining the coordinates of image maps can be tedious and error prone.
We prevent people from submitting a contact without entering values for required form fields. Save Changes() Return Redirect To Action("Index") Catch Return View() End Try End Function End Class In this iteration, we added basic form validation to our Contact Manager application.
We also validate phone numbers and email addresses (see Figure 1). Our validation logic prevents users from submitting a new contact or editing an existing contact without supplying values for the First Name and Last Name properties.
Combined files are a way to reduce the number of HTTP requests by combining all scripts into a single script, and similarly combining all CSS into a single stylesheet.
As described in Tenni Theurer's blog post Browser Cache Usage - Exposed!Inline images are not yet supported across all major browsers.Reducing the number of HTTP requests in your page is the place to start.Image maps combine multiple images into a single image.The overall size is about the same, but reducing the number of HTTP requests speeds up the page.In the next iteration, we refactor the Contact Manager application to make the application more maintainable. First Or Default() Return View(contact To Delete) End Function ' ' POST: /Contact/Delete/5 _ Function Delete(By Val contact To Delete As Contact) As Action Result Try Dim original Contact = (from c in _entities. However, mixing our validation logic into our controller logic will create problems for us in the long term.In this iteration, to keep things simple, we write all of the validation code by hand. Save Changes() Return Redirect To Action("Index") Catch Return View() End Try End Function ' ' GET: /Contact/Delete/5 Function Delete(By Val id As Integer) As Action Result Dim contact To Delete = (from c in _entities. Our application will be more difficult to maintain and modify over time.The goal of this multiple iteration approach is to enable you to understand the reason for each change.In this second iteration of the Contact Manager application, we add basic form validation.But is there a way to build pages with richer content while also achieving fast response times?Here are some techniques for reducing the number of HTTP requests, while still supporting rich page designs.
