What is the web page source code?

Website source code, also known as source code, source program, refers to uncompiled text code or all source code files of a website. It is a series of human-readable computer language instructions; after translation through a browser or server This is the final effect that users see. Website source code can be divided into two types, one is dynamic source code such as ASP, PHP, JSP, .NET, etc.; the other is static source code such as HTML, etc.

Website source code, also known as source code, source program. It refers to uncompiled text code or all source code files of a website, which is a series of human-readable computer language instructions. We can understand it as source code. As for the webpage we are currently seeing, it is actually composed of a lot of source code. Through our browser (such as Microsoft's IE browser, Google's Chrome browser, etc.) Or the server translates it into what we see.

The web pages we usually see are generally written by one to multiple source codes.

Website source code is divided into two types, one is dynamic source code such as: ASP, PHP, JSP, .NET, CGI, etc., and the other is static source code such as: HTML, etc.

• Dynamic source code

  Programs, web pages, and components running on the server are dynamic web pages. They will change with different customers and at different times. Return different web pages, such as ASP, PHP, JSP, NET, CGI, etc.

  The biggest feature is the ability to interact with users. For example, in NetEase's mailbox, when Zhang San logs in, he will see Welcome to Zhang San, Li Si logs in again, and Li Si sees Welcome to Li Si again. In fact, the two of them log in to the same page. This is the dynamic source code. The advantage is that if you use static source code, it seems that NetEase has millions of email users. How many pages does it take for each person to make a page? Dynamic source code is not only useful for this, for example, some of our common forums, guest books, Counters, chat rooms, etc. are all developed from dynamic source code. The biggest feature of dynamic source code is that it has a database, such as ACCESS, SQL, MYSQL, etc.! The characteristic of this type of website source code is that it has background management. Compared with static source code, this type of website source code is not easy to be included by search engines!

• Static source code

  Programs, web pages, plug-ins, and components that run on the client are static web pages, such as html pages, Flash, JavaScript, VBScript, etc., they will never change.

  For example, the web page we are currently seeing is a static source code. Static source code cannot achieve the above functions. There is no backend, but it is easily indexed by search engines.

  There are many source code download sites. The downloaded source code files are basically incomplete and can only be used as a reference for learning. If you want to use such source code, you must modify it by professional programmers before you can use it. If If you are a website developer, you can go to Taobao to purchase source code. This source code is generally relatively complete. Of course, there are also incomplete ones, but you can build your own website with just a few modifications.

• Static and dynamic

  Whether the program is running on the server side is an important sign to distinguish static web pages from dynamic ones.

  Static web pages and dynamic web pages have their own characteristics. Whether the website uses dynamic web pages or static web pages mainly depends on the functional requirements of the website and the amount of website content. If the website function is relatively simple and the amount of content updates is not large, pure The static web page method will be simpler, but dynamic web page technology is generally used to achieve it.

  Static web pages are the basis of website construction. There is no contradiction between static web pages and dynamic web pages. In order for the website to adapt to the needs of search engine retrieval, even if dynamic website technology is used, web content can be converted into static web pages. release.

  Dynamic websites can also adopt the principle of combining static and dynamic ones. Where dynamic web pages are suitable, use dynamic web pages. If static web pages are necessary, you can consider using static web pages to achieve it. On the same website, It is also common for dynamic web content and static web content to exist at the same time.

The main function of the website source code

generates target code, that is, code that can be recognized by computers.

Describe the software, that is, explain the writing of the software. Many beginners and even a few experienced programmers ignore the writing of software descriptions, because although this part will not be directly displayed in the generated program, it will not be involved in compilation. But it shows that it has huge benefits for software learning, sharing, maintenance and software reuse. Therefore, writing software descriptions is considered a good habit in the industry to create excellent programs, and some companies also make it mandatory to write it.

It should be pointed out that modification of the source code cannot change the generated target code. If the target code needs to be modified accordingly, it must be recompiled.

How to view the source code of a web page?

Open any website, right-click, and click "View Source Code". The notepad that pops up at this time is the source file of the website, which contains the code structure of the web page. Through these codes, you can understand what website building program other people use to write their websites.
