The writing of webpage (asp,jsp) from the nature

js| Web page

Learn to write Web pages from the beginning of ASP, at that time saw some video of the Beida Bluebird, of course, the teacher of the nature of the Web page is very clear! This also saves me a lot of time!

In fact, the most afraid of learning things, you go to copy what the teacher taught you! What do you mean? In other words, you can only make notes, but not to understand! Not catch the essence of things!

Now from our own use of IE to start it, we have to enter the address bar www.baidu.com, at this time did not open to the Baidu home page! (Campus network How a slow word get) This process believe that everyone is familiar with! But the concrete process here can be regarded as a classic model!

Here is a two-part, IE browser (client), Baidu's server. When you enter a URL address to the address bar, you send a request to the server, and when the server accepts the request, it must respond, that is, feedback (response). Then our client receives the feedback and displays what we want in the browser!

When we get this thing figured out, look at the asp,jsp! we wrote. asp,jsp are dynamic, because they can dynamically change the customer's request, which means they have the ability to handle events! So the asp,jsp must be on the server! In other words, we develop the server, it is on the server, is on the server! Because the customer service side is unable to understand asp,jsp, they want to execute on the server! Understanding these basically knows, our asp,jsp code is to request to obtain the customer service end through requests, through response to respond the request.

When we understand, we will find that the asynchronous in Ajax, it is actually such a process! We are also going to the process of it to programming!
