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]:
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; }}
private List<FivePhases> GetFivePhases() { List<FivePhases> ListFH = new List<FivePhases>(); 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。
<asp:CheckBoxList ID="RadioButtonListFivePhases" runat="server" RepeatDirection="Horizontal"></asp:CheckBoxList>
然后在cs绑定数据：
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：
<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。
<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>
