Learning about JSP and HTML in the past two days

Some time ago I thought about how to learn things by myself. It was like a dog, a bear, and a corn. I learned one, lost one, But I still wrote a log and saved my footprints!

201012.17 started downloading tomcat6.0 and mysql5, and developed a desktop based on the original eclipse (which has not been implemented but has not been implemented and watched the two-day video ).ProgramConnect to the database.

201012.18. I plan to go to Taishan, Shandong province, or Huangshan, Anhui province next time.

I started learning from 201012.19 to the afternoon. I made a simple web page, entered the user name, and returned the password. This is expensive. At first, I thought there was a problem with the SQL writing on the server side and did not return the correct value. Later I switched to prestatement. After a long time, I thought of outputting SQL statements on the server, so that I could find that there was a problem with the SQL statements, but not the server side. Instead, the parameters passed by the client via Ajax in post mode were empty. Later, I could not do it. I changed it to the get method and it would be OK. Of course, there is something handy for the DIV pop-up box, haha. In fact, there are still some gains in the past two days.

20101220 today, I am a little tired at work, don't want to work, and I have to find a ticket again. This is the most depressing time of the month. After studying IFRAME users in the afternoon, I found out how to modify other people's programs. The layout will not be afraid in the future. Iframe(html,javascript,javasparent.doc ument. getelementbyid (). SRC and other operations in the general metrics to change the IFRAME content). 2. It is the. NET master page or user-defined control. Here, I have a question: Is JSP implemented through the custom tag library? I have heard of the tag library, but I have never studied it... If you have the opportunity to take a look, the technology itself is not important. What matters is that you take him to make things. Now we are more and more aware of the importance of the business layer.
