Visualforce is a development framework used in Salesforce to build custom user interfaces. It includes a markup language called Visualforce Markup Language (VFML) and a controller, which is responsible for handling user interactions and manipulating data. Visualforce controller developers need to have experience with various technologies to build robust applications.
Out of the given options, two technologies that are useful for Visualforce controller developers to have experience with are HTML and JavaScript.
HTML (Hypertext Markup Language) is the standard markup language used to create web pages. Visualforce uses HTML to create user interfaces. The knowledge of HTML is essential for Visualforce controller developers to build custom user interfaces, as they need to be proficient in HTML tags, attributes, and elements. With HTML knowledge, developers can create Visualforce pages with proper formatting, styling, and layout.
JavaScript is a programming language used to make web pages interactive. Visualforce uses JavaScript to add functionality to custom user interfaces. Visualforce controller developers need to have experience with JavaScript to create dynamic user interfaces, such as dropdown menus, tabs, and pop-ups. JavaScript also allows developers to perform form validations, make AJAX calls, and handle user events.
Java and Java Server Pages (JSP) are not essential for Visualforce controller developers to have experience with, as they are not used in the development of Visualforce pages. However, if developers have experience with Java and JSP, it may help them understand the underlying principles of Visualforce and enhance their overall development skills.
In conclusion, Visualforce controller developers need to have experience with HTML and JavaScript to build custom user interfaces and add interactivity to Visualforce pages. While Java and JSP are not essential, experience with these technologies may help developers enhance their overall development skills.
