Design a Web page using Ajax for registering an electronic product, either hardware or software. The form should have the purchaser’s name and address, telephone number, email address, and a drop-down list of product categories. When the category is changed, send the category value to the server, which returns an X M L document containing the products for the category, used to create a drop-down list of products. When the customer selects a product, the product value is sent to the server, which returns an X M L document used to create a model or version of the product.
The radio buttons are optional, and students may choose not to include them. Their inclusion may work in two ways:
A. They could be used to verify that the selected product was hardware or software
B. They could be used to populate the product category drop-down list. In this case, the product category drop-down list should have the initial value “—Selection Unavailable—.”
