onmouseover和onmouseout应用于RadioButtonList或CheckBoxList

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

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;
        }
}

View Code

 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。

View Code

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

然后在cs绑定数据：

View Code

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：

View Code

<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。

View Code

<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>
