工作学习 / 学科技术讨论 / 特记之：用ajax 完成数据库表格的翻页，单个记录引发其它表格的更新，终于做成功。Oracle ADF, 没啥新鲜的了。

It is not a simple ajax call from client, what I do is to design a general mechanism in a portal environment for data portlet local refresh, which includes portlet prop registration, session var control, SQL stat mgmt.

How many records can your "数据库表格的翻页" handle?

Each portlet has attributes registered in system table, state is one of them, each state has its own number of rows. Portlet will choose a state in a specific page, and engine will deliver based on those definitions.MySql's LIMIT keyword is very helpful. I don't remember in Pl/SQL, or TSQL, there is such a feature to limit output from a designated starting row number. Maybe they have....

all you've done has been achieved by others. Look at Tibco General Interface, it's grid can handle 20K records (with column sort, rearrange of columns ) very fast.

I will do it too: Column background/font size/color, width adjustment, column position change / sorting, category collapse/expend, and data modification on cells, rollback/confirm, without any more plug-ins.

Multi-browser support is a great PAIN, and I now focus IE, because it is a standard in most enterprise intranet. Design pattern is changing rapidly, the current ajax-driven design makes webpage looks like a desktop, is cool.

I used all of them, plus JDeveloper. IDE is a great help because it makes things easier organized, but just like using vi instead of notepad, I like command line tool, and like to write plain text code by hand. There is no visual tool yet.

Wheel has been invented, what I am doing is to make a car, using my own patent, using my own brand. I don't care how many cars on the road, how many brands, dealers on the street corner, I believe my design makes sense and will have buyer.

Just my two cents, I won't put anything related with DB operation into javascript.

There will be no Db direct call from JS, it calls server handler and then beans. What I found is srv produces html element and onclick code which is based on id it knows, but after ajax refresh, those ids have been changed and JS knows nothing about it.So JS onclick function still linked to those old IDs,,,,,, During ajax calls, you refresh element's interHTML, JS script is beyond your control,,,....
I fixed it by transfering local placeholder number, and then retrieving element's actual id....

Ajax的精髓主要还是JAVASCRIPT. 所以说十年前就能实现你所说的功能也是对的.

If you work in someone else's env, you rely on the public APIs they offer to you to do further development in their security sandbox. If they don't open xmlhttprequest, you can do nothing. Same for calling foreign URL from JS, they answer you "No".I talked about some problem I had in ajax development, nothing else. If you have interest to discuss those tech detail, go ahead. If you think you are better than me, congratulations! :-)

说多就显嫩了不是? AJAX虽然不到十年, 但之前有许多方法可以达到类似功效, 最常用的是IFRAME/DHTML, 也就是用一个Hidden Iframe来动态与后台交换数据, 然后用DHTML替换JavaScript/HTML的variable. 其效果基本上可以达到AJAX. 只是编程比较复杂, 用得不太流行而已.再顺便说一下, AJAX技术你如果六七年前拿出来讲, 大家会觉得你COOL. 现在早变成web programmer的基本技术, 就不要再拿出来显了, 你那么资深的人士让人当JUNIOR看就不好玩了.

现在流行的是不用 frameset, iFrame. Frameset causes ugly UI, inconsistent look. iframe is IE-only. (?), Ajax 用的是普遍了，但很多情况下是下拉菜单，用户名校验，等等。当然它并不复杂，我只是想把自己的系统做成desktop like, just try....

你替换的只是element value (innerHTML, for example), you cannot simply replace dynamically any javascript code, and parameter which attaches to the element. So for simply replace display value replace, that is fine, But JS link will be broken, unless..you write event listener, or re-write document.

If you use hidden Iframe to exchange data, my guess is that the iframe can be used only once, you cannot reload the iframe without refreshing the whole page. Am I wrong?

通过Hidden Frame(IFrame)也是AJAX的一种实现方法。XMLHttpRequest 与Hidden Frame分别用在不同的场合下。大型的网站往往会兼用这两种方法。
