Programming Articles

In the last two articles about CRUD and HTML (CODE Magazine, November/December 2015 and January/February 2016), you created a product information page to display a list of product data returned from a Web API. In addition, you built functionality to add, update, and delete products using the same Web API controller. In those two articles, there was a very basic exception handler function named handleException. This function displays error information returned from the API in an alert dialog on your page, as shown in Figure 1.
