Developing Web Applications

Client-Side Script

Client-side scripts run within the user’s browser, using the processing power of the user’s (client) computer. They can be written in any language supported by the browser; the most common is JavaScript, which is supported by most browsers. Some browsers, such as Internet Explorer, also support Microsoft® Visual Basic® Scripting Edition (VBScript). Client-side scripting enhances Web pages with a variety of custom capabilities. For example, you can use scripts to perform field edits and calculations, manipulate the client window, or validate form input. Scripts normally appear directly on the page they affect, but they can be used to manipulate the content of pages in another frame or browser window as well. For more information about browser support for client-side technologies, see Table 6.1 in the topic Browser Support.
