Failsafe RemoteImages

When you use images from other sites in your web page you run the risk of the other web site being down and the images not being able to be displayed. Here is a script that can detect when that happens and substitute a different image.

      To Index or nottoIndex

      Some indexes make the database faster while others make it slower. It all depends on how frequently the index is used and how often the table is updated.

        DynamicJavaScriptForms

        If you are going to have a form in your web page that will only work when JavaScript is enabled then the form should only appear when JavaScript is enabled. This means that you should be adding the form to the page using JavaScript. This script provides a JavaScript object that has methods for creating forms and adding all of the different form field types.

          Why Web Sites DisplayAdvertising

          Few people actually like seeing advertising on web pages so why are there ads displayed on so many pages? Well the thing is that the cost of creating and maintaining the pages needs to be paid by someone and the alternative ways by which it can be paid for are not necessarily ones that people who dislike advertising would prefer to see instead. Perhaps advertising isn’t so bad after all provided that it is done in an appropriate way.

              Closures and Scope

              Closures are one of the most misunderstood parts of JavaScript. I have even seen articles attempting to clarify what closures are that just add to the confusion. Well here’s my attempt to explain it which you will hopefully find less confusing than some of the others.

                Sparse Arrays

                JavaScript derives its Arrays from Objects. Effectively a JavaScript Array is an object where some of the properties have numbers as their names. This means that the numbers need not be continuous. Where the numbers have gaps we have what is known as a sparse array. The missing numbers don’t have values at all – not even undefined. The Array methods skip over missing numbers making using the methods for array processing a better alternative to loops.

                      More AboutPost-Redirect-Get

                      While you can avoid the whole issue of messages about data being reposted by using a browser that doesn’t produce those messages and avoid any issues if data is posted again by coding the receiving script to identify it and handle it appropriately, that doesn’t resolve things for those visitors to your site who are using a browser that insists on producing those warning messages. It may be worthwhile implementing Post-Redirect-Get just to get rid of meaningless error messages in dumb browsers.

                        Plugins andExtensions

                        There is more to browsers than what you can do with the browser itself. Most browsers have a number of plugins and/or extensions available that you can add to your browser to enhance its functioning.
