This article introduces the knowledge of "are javascript and asp scripting languages?". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Both javascript and asp are scripting languages. JavaScript is a browser-side scripting language, which is often used to add a variety of dynamic functions to web pages to provide users with a more smooth and beautiful browsing effect, while asp is a server-side scripting language that can be used to create dynamic interactive web pages and build powerful web applications.

The operating environment of this tutorial: windows7 system, javascript1.8.5 version, Dell G3 computer.

Both javascript and asp are scripting languages. JavaScript is a browser-side scripting language, while asp is a server-side scripting language.

JavaScript introduction

JavaScript is a client-side (browser-side) scripting language based on object and event-driven and relatively secure. It is also a scripting language widely used in client-side Web development. It has been widely used in Web application development, often used to add a variety of dynamic functions to web pages, and provide users with a more smooth and beautiful browsing effect.

Originally designed by Brendan Eich of Netscape, it is a dynamic, weakly typed, prototype-based language with built-in support for classes. JavaScript is a registered trademark of Sun Corporation (which has been acquired by Oracle). Ecma International has formulated the ECMAScript standard based on JavaScript.

The complete JavaScript implementation consists of three parts: ECMAScript, document object model, and browser object model.

JavaScript can be used in various areas of Web development, such as:

Web application development: the web pages we browse in our daily life are made up of HTML, CSS and JavaScript. Through JavaScript, we can update the style of the elements in the web page in real time, and realize the interaction between people and the web page (such as monitoring whether the user clicked the mouse or pressed a button, etc.), and can also add some cool animation to the web page.

Mobile application development: in addition to Web application development, JavaScript can also be used to develop applications on mobile phones or tablets, and we can also use some excellent frameworks (such as React Native) to make development easier

Web games: the Mini Game that we have played on the web page can be implemented using JavaScript

Back-end Web application development: in the past, we all used JavaScript to develop the front-end part of Web applications, but with the emergence of Node.JS (a JavaScript runtime environment), JavaScript can also be used to develop the back-end part of Web applications.

Asp introduction

ASP, namely Active Server Pages, is a server-side scripting environment developed by Microsoft, which can be used to create dynamic interactive web pages and build powerful web applications.

When the server receives a request for an ASP file, it processes the server-side script code contained in the HTML web page file that is used to build the Web page file sent to the browser. In addition to server-side script code, ASP files can also contain text, HTML (including related client-side script), and com component calls.

ASP is simple, easy to maintain, and is the choice of small page applications. With DCOM (Distributed Component Object Model) and MTS (Microsoft Transaction Server), ASP can even implement medium-sized enterprise applications.

The difference between javascript and asp

ASP is executed by the server, so it allows you to process HTTP request headers (cookie, web page references, user agent strings and other personal information sent by the browser during the request, etc.), connect to the database and run on them, read or write log files, etc., and even run some programs on the server.

Therefore, it can generate dynamic HTML content and provide it to the user's browser. For example, the login page requires a server-side script (in ASP,PHP... To check the validity of the login and password (fixed text, information from the database.) and generate the appropriate HTML content.

JavaScript, on the other hand, has limited access to HTTP headers and cannot perform any action on the server side (because it runs on the visitor's browser).

However, it can respond to and interact with user actions on a web page generated by the server (the server tells the browser what options the user can use and what to do in response to the user's actions).

Javascript is more limited, but it provides tools to extend the behavior of web pages when the server finishes processing and loses control of it. The basic function of verification.
