atlas学习系列一(简单体验)
学习atlas有一段时间了,培训讲座也听了些,但是具体没有使用过,准备写一个atlas学习系列,从简单的开始,逐一学习总结一下atlas的
用法,本文介绍如何使用atlas来支持简单的无刷新效果。主要目的是体会一下atlas的强大功能。用的也是atlas官方demo,大家可以在它网站
上下载,自己只是简单重复的实践了一把。

1.atlas:ScriptManager :我揣摩加上这个标签,页面就注册了一下调用服务器端ajax代码的js,从原文件中也可以看出,在相应位置,产生如下代码为:
<script src="/AtlasSimpleDemo1/WebResource.axd?d=3gMGO8vzpNXUSzrvQy_2DWGsjQkw1bBJAFDl2m1MpwDm2AZlxbopKEnT5eJLSEwvAiV62wgEk-T92L62_VXqXS2eRY-oB8mtk5RkTqZ5wSM1&t=632870166220000000" type="text/javascript"></script>
<script src="atlasglob.axd" type="text/javascript"></script>
2.atlas:UpdateProgress , ProgressTemplate
生成一个div标签,以后更改div的visiable。
3。atlas:UpdatePanel
a. ContentTemplate 我估计加上这种标签,相当于将该标签下的控件变成ajax控件,即交互都通过xmlhttp来实现。
b.Triggers 这个标签用来处理页面事件。分为两类
1)atlas:ControlValueTrigger : 控件值触发,比如设置控件为DropDownList1,源代码中就在DropDownList1控件生成的Select表单加上onchange= "javascript:setTimeout('__doPostBack(\'ctl00$ContentPlaceHolder1$DropDownList1\',\'\')', 0)"如下语句。这样就可以触发该控件的事件了。
2)atlas:ControlEventTrigger:估计是截取控件事件,将js方法写到指定方法中。
先写道这里,有空写下一篇。
