JavaScript som server-side-scripting-språk

[ilpostino]

Har en lærer som påstod at en helt greit kunne bruke JavaScript som server-side-scripting-språk. Jeg hevder dette er feil...

 

Såvidt jeg vet kan en bytte ut VBScript med JavaScript i ASP..... skal en ellers benytte JavaScript skjer dette på klient-siden, ikkesant?

[enden]

tror nok læreren din tar litt feil der ja. js er rent client-side

VBScript er en uting, uansett hvor det kjører.

Læreren har faktisk helt rett. Man kan kjøre JavaScript som server-side, men det bør nevnes at det ikke er så vanlig, sannsyligvis fordi JavaScript har slitt med sikkerhetsproblemer. Et søk på google gir deg masse info om server-side JavaScript. Her er en liten forklaring på hva javascript er, som jeg fant:

 

What Is JavaScript?  

JavaScript is Netscape's cross-platform, object-oriented scripting language. Core JavaScript contains a core set of objects, such as Array, Date, and Math, and a core set of language elements such as operators, control structures, and statements. Core JavaScript can be extended for a variety of purposes by supplementing it with additional objects; for example:

 

 

Client-side JavaScript extends the core language by supplying objects to control a browser (Navigator or another web browser) and its Document Object Model (DOM). For example, client-side extensions allow an application to place elements on an HTML form and respond to user events such as mouse clicks, form input, and page navigation.  

 

Server-side JavaScript extends the core language by supplying objects relevant to running JavaScript on a server. For example, server-side extensions allow an application to communicate with a relational database, provide continuity of information from one invocation to another of the application, or perform file manipulations on a server.  

JavaScript lets you create applications that run over the Internet. Client applications run in a browser, such as Netscape Navigator, and server applications run on a server, such as Netscape Enterprise Server. Using JavaScript, you can create dynamic HTML pages that process user input and maintain persistent data using special objects, files, and relational databases.

 

Through JavaScript's LiveConnect functionality, you can let Java and JavaScript code communicate with each other. From JavaScript, you can instantiate Java objects and access their public methods and fields. From Java, you can access JavaScript objects, properties, and methods.

 

Netscape invented JavaScript, and JavaScript was first used in Netscape browsers.
