实现onmouseover和onmouseout应用于RadioButtonList或CheckBoxList控件上

一直想实现onmouseover和onmouseout应用于RadioButtonList或CheckBoxList控件上，今晚终于有时间实现它。此功能就是当鼠标经过时RadioButtonList或CheckBoxList每一个Item时，让Item有特效显示，离开时，恢复原样。可以看到效果：

RadioButtonList效果：

CheckBoxList效果：

这资实现数据，Insus.NET准备了五行（Five Phases）

创建一个对象[Five Phases]:
FivePhases.cs

复制代码代码如下:

 
using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 

/// summary> 
/// Summary description for FivePhases 
/// /summary> 
public class FivePhases 
{ 
private int _ID; 
private string _Name; 

public int ID 
{ 
get { return _ID; } 
set { _ID = value; } 
} 

public string Name 
{ 
get { return _Name; } 
set { _Name = value; } 
} 

public FivePhases() 
{ 
// 
// TODO: Add constructor logic here 
// 
} 

public FivePhases(int id, string name) 
{ 
this.ID = id; 
this._Name = name; 
} 
} 

复制代码代码如下:

 
private ListFivePhases> GetFivePhases() 
{ 
ListFivePhases> ListFH = new ListFivePhases>(); 
FivePhases fh = new FivePhases(); 
fh.ID = 1; 
fh.Name = "木"; 
ListFH.Add(fh); 

fh = new FivePhases(); 
fh.ID = 2; 
fh.Name = "火"; 
ListFH.Add(fh); 

fh = new FivePhases(); 
fh.ID = 3; 
fh.Name = "土"; 
ListFH.Add(fh); 

fh = new FivePhases(); 
fh.ID = 4; 
fh.Name = "金"; 
ListFH.Add(fh); 

fh = new FivePhases(); 
fh.ID = 5; 
fh.Name = "水"; 
ListFH.Add(fh); 

return ListFH; 
} 

此时，你可以拉一个RadioButtonList或是CheckBoxList控件至网页中，此例以RadioButtonList控件为例。

复制代码代码如下:

asp:CheckBoxList ID="RadioButtonListFivePhases" runat="server" RepeatDirection="Horizontal">/asp:CheckBoxList>

然后在cs绑定数据：

复制代码代码如下:

 
using System.Data.OleDb; 
using System.Linq; 
using System.Web; 
using System.Web.UI; 
using System.Web.UI.WebControls; 
using Insus.NET; 

public partial class _Default : System.Web.UI.Page 
{ 
protected void Page_Load(object sender, EventArgs e) 
{ 
if (!IsPostBack) 
Data_Binding(); 
} 

private void Data_Binding() 
{ 
this.RadioButtonListFivePhases.DataSource = GetFivePhases(); 
this.RadioButtonListFivePhases.DataTextField = "Name"; 
this.RadioButtonListFivePhases.DataValueField = "ID"; 
this.RadioButtonListFivePhases.DataBind(); 
} 

} 

还得准备鼠标的over与out样式：

复制代码代码如下:

 
style type="text/css"> 
.overStyle { 
font-weight: bold; 
color: #f00; 
} 

.outStyle { 
font-weight: normal; 
color: none; 
} 
/style> 

在Javascript中实现每个Item有onmouseover和onmouseout事件，因此还得写Javascript脚本，放于head>内。

复制代码代码如下:

 
script type="text/javascript"> 
function windowOnLoad() { 
var rbl = document.getElementById('%= RadioButtonListFivePhases.ClientID %>'); 
var labels = rbl.getElementsByTagName('label'); 

for (var i = 0; i  labels.length; i++) { 
var lbl = labels[i]; 

lbl.onmouseover = function () { 
this.className = 'overStyle'; 
}; 

lbl.onmouseout = function () { 
this.className = 'outStyle'; 
}; 
} 
} 
window.onload = windowOnLoad; 
/script>
