1.Button控件示例
上一篇简单介绍了Atlas的客户端控件,都是一些理论性的东西,显得有些枯燥。本文以Button控件为示例,看一下客户端简单控件的一些使用。前面说过,Atlas将DOM元素中的Button概念扩展,使Button不单单指type为button或submit的HTML input元素,还可以应用到例如span,a等元素上,提供开发人员统一的编程接口。
1.添加Input,Button,a,span四个DOM元素:
![](/Images/OutliningIndicators/None.gif)
![](/Images/OutliningIndicators/None.gif)
![](/Images/OutliningIndicators/None.gif)
![](/Images/OutliningIndicators/None.gif)
![](/Images/OutliningIndicators/None.gif)
![](/Images/OutliningIndicators/None.gif)
![](/Images/OutliningIndicators/None.gif)
分别表示为Button1,Button2,Button3,Button4。再添加一个Span用来显示单击按钮后的结果:
![](/Images/OutliningIndicators/None.gif)
2.添加Atlas客户端控件:
前面说过,Sys.Component是所有的Atlas客户端控件的抽象基类,而所有的控件都有一个ID属性,它的解释为Atlas组件的标识符,将Atlas客户端组件与DOM元素连接起来。这个id值与DOM元素的id属性值相同,Atlas使用这个id以找到相关的DOM元素。
添加一个Atlas的Label控件,设置它的ID与我们上面的Span ID一致:

前三个Button我们只是加上Click,而对第四个Button还加上了hoverBehavior,分别设置参数如下:

这里的参数很简单,有关的方法和属性可以参考前一篇文章。其中用的CSS样式:

![](/Images/OutliningIndicators/ExpandedBlockEnd.gif)
![](/Images/OutliningIndicators/None.gif)
![](/Images/OutliningIndicators/None.gif)
运行后如下:
单击Button1后:
鼠标移动到Button4上:
单击Button4后:
