S-Control Components

AC.

S-controls in Salesforce are a type of custom component that allow you to extend the functionality of standard Salesforce pages by embedding custom HTML, CSS, and JavaScript code. Typically, s-controls consist of two major pieces: HTML (Visual Presentation) and Javascript (Function/Code).

1. HTML (Visual Presentation): HTML stands for HyperText Markup Language. It is the standard markup language used to create web pages. In s-controls, HTML is used to define the structure and layout of the user interface that will be displayed on the page. This includes things like text, images, forms, tables, and other elements that make up the visual presentation of the s-control.

2. Javascript (Function/Code): Javascript is a programming language used to add interactivity and dynamic functionality to web pages. In s-controls, Javascript is used to define the behavior and logic of the user interface. This includes things like event handling, data manipulation, and other functionality that is required to make the s-control work as intended. For example, you might use Javascript to validate form input, perform calculations, or make calls to the Salesforce API.

While CSS (Cascading Style Sheets) is often used in conjunction with HTML to control the visual style of web pages, it is not considered a major piece of s-controls. However, it can be used to style the HTML elements within an s-control to make it look more visually appealing and consistent with the overall Salesforce user interface. Similarly, IFrame can be used in some cases to embed external content or web applications within the s-control, but it is not a necessary component for most s-controls.
