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 dropdown list of product categories. When the category is changed, send the category value to the server, which returns an XML document containing the products for the category, used to create a dropdown list of products. When the customer selects a product, the product value is sent to the server, which returns an XML document used to create a model or version of the product.
