Client-Side JavaScript
Client-side JavaScript is the most common form of the language. The script should be included in or referenced by an HTML document for the code to be interpreted by the browser.
It means that a web page need not be a static HTML, but can include programs that interact with the user, control the browser, and dynamically create HTML content.
The JavaScript client-side mechanism provides many advantages over traditional CGICGI (Common Gateway Interface) programs are programs that exist, and are run on, a web server. They are normally run by a client computer by clicking a button in their browser. CGI programs usually perform some task like a search, or storing information on the server, and also normally generate a dy... server-sideServer-side scripting is a technique used in web development which involves employing scripts on a web server which produce a response customized for each user's (client's) request to the website. The alternative is for the web server itself to deliver a static web page. Scripts can be written in an... scripts. For example, you might use JavaScript to check if the user has entered a valid e-mail address in a form field.
The JavaScript code is executed when the user submits the form, and only if all the entries are valid, they would be submitted to the Web Server.
JavaScript can be used to trap user-initiated events such as button clicks, link navigationSite architecture, menus and other navigation tools in the web design must be created with consideration of how users browse and search. The goal is to help the user to move around the site with ease, efficiently finding the information they require., and other actions that the user initiates explicitly or implicitly.
Advantages of JavaScript
The merits of using JavaScript are −
- Less server interaction − You can validate user input before sending the page off to the server. This saves server traffic, which means less load on your server.
- Immediate feedback to the visitors − They don’t have to wait for a page reload to see if they have forgotten to enter something.
- Increased interactivity − You can create interfaces that react when the user hovers over them with a mouse or activates them via the keyboard.
- Richer interfaces − You can use JavaScript to include such items as drag-and-drop components and sliders to give a Rich Interface to your site visitors.
