<div>Option 1</div>

</div>

<div>

Test.js代码如下:

var selectedOptions=new Array();

var txtBuilder=new Sys.StringBuilder();

//为该Dom元素添加事件处理函数

function createButton(elem)

{

$addHandlers(

elem,

{

mouseover:showHoverStyle,

mouseout:showDefaultStyle,

click:handleClick

}

);

}

function showHoverStyle()

{

if(!Sys.UI.DomElement.containsCssClass(this,"clicked"))

{

Sys.UI.DomElement.addCssClass(this,"hover");

}

//在mosu从某个选项上移开时

function showDefaultStyle()

{

Sys.UI.DomElement.removeCssClass(this,"hover");

}

function handleClick()

{

Sys.UI.DomElement.removeCssClass(this,"hover");

Sys.UI.DomElement.toggleCssClass(this,"clicked");

if(Sys.UI.DomElement.containsCssClass(this,"clicked"))

{

if(!Array.contains(selectedOptions,this.innerHTML))

{

Array.add(selectedOptions,this.innerHTML);

}

else

{

Array.remove(selectedOptions,this.innerHTML);

}

//创建选项字符串

txtBuilder=null;

for(var index=0;index<selectedOptions.length;++index)

{

txtBuilder.append(selectedOptions[index]);

}

//设置并显示到页面中

$get("selectedOptions").innerHTML=txtBuilder.toString(", ");

}

function pageLoad()

{

var childNodes=$get("buttonContainer").childNodes;

var count=childNodes.length;

for(var index=0;index<count;++index)

{

createButton(childNodes[index]);

}

//nogifyScript()方法是Sys.Application对象提供的一个重要功能,

//用来在该脚本资源成功加载至客户端浏览器后告知ASP.NET AJAX客户端运行时.

if(typeof(Sys)!=="undefined")

Sys.Application.notifyScriptLoaded();
