问题描述

Q1：有什么样太多AJAX ??

说明：     我已经看到使用Ajax / jQuery的等在那里，我认为它甚至不需要编程。我建了一个报表工具，为公司的高级管理人员（年龄55+）和不得不重构多页，实际上取出ajaxy的东西从它。这些东西在要求处理，还是我们在看AJAX矫枉过正？

Explanation: I have been seeing programmers using Ajax/jQuery etc where I think its not even required. I had built a reporting tool for the company's senior management ( age group 55+) and had to refactor many pages and actually take out the ajaxy stuff from it. Are these things to be handled in requirements or are we looking at AJAX overkill?

Explanation: I have a page that has multi-level master detail functionality. You may call it a drilldown interface that also allows CRUD operations. I am using UpdatePanels in some cases. At times due to browser repainting the page the focus is lost. How do you handle something like that?

推荐答案

我觉得有绝对太多了阿贾克斯。许多开发人员没有意识到，这是很不自由的。您正在使用的服务器的连接，有可能建立一个从无到有的新连接，根据服务器保持活动设置。

I think there is absolutely too much Ajax. A lot of developers don't realize that it is far from free. You are using a connection to the server, possibly establishing a new connection from scratch depending on server keep-alive settings.

如果您使用的是像PHP语言在服务器上，它使事情差远了，因为PHP有​​重载code从零开始为每个连接。

If you are using a language like PHP on the server, it makes things far worse since PHP has to reload code from scratch for every connection.

至于屏幕尺寸调整失去焦点。你可以设置，记录当前焦点变量，然后在窗口重新调整的重点？

As for losing focus on screen resize. Could you set a variable that records the current focus, then on window resize reset the focus?
