限制CheckBoxList控件只能单选实现代码及演示动画

复制代码 代码如下:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
/// <summary>
/// Summary description for TerrestrialBranch
/// </summary>
namespace Insus.NET
{
public class TerrestrialBranch
{
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 TerrestrialBranch()
{
//
// TODO: Add constructor logic here
//
}
public TerrestrialBranch(int id, string name)
{
this.ID = id;
this._Name = name;
}
}
}

复制代码 代码如下:

private List<TerrestrialBranch> GetData()
{
List<TerrestrialBranch> tbs = new List<TerrestrialBranch>();
tbs.Add(new TerrestrialBranch(1,"子"));
tbs.Add(new TerrestrialBranch(2, "丑"));
tbs.Add(new TerrestrialBranch(3, "寅"));
tbs.Add(new TerrestrialBranch(4, "卯"));
tbs.Add(new TerrestrialBranch(5, "辰"));
tbs.Add(new TerrestrialBranch(6, "巳"));
tbs.Add(new TerrestrialBranch(7, "午"));
tbs.Add(new TerrestrialBranch(8, "未"));
tbs.Add(new TerrestrialBranch(9, "申"));
tbs.Add(new TerrestrialBranch(10, "酉"));
tbs.Add(new TerrestrialBranch(11, "戌"));
tbs.Add(new TerrestrialBranch(12, "亥"));
return tbs;
}

复制代码 代码如下:

<asp:CheckBoxList runat="server" RepeatColumns="6" RepeatDirection="Horizontal"></asp:CheckBoxList>

复制代码 代码如下:

using System;
using System.Collections.Generic;
using System.Data;
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.CheckBoxListTerrestrialBranch.DataSource = GetData();
this.CheckBoxListTerrestrialBranch.DataTextField = "Name";
this.CheckBoxListTerrestrialBranch.DataValueField = "ID";
this.CheckBoxListTerrestrialBranch.DataBind();
}
}

复制代码 代码如下:

window.onload = function () {
var cbl = document.getElementById('<%= CheckBoxListTerrestrialBranch.ClientID %>')
var inputs = cbl.getElementsByTagName("input");
for (var i = 0; i < inputs.length; i++) {
if (inputs[i].type == "checkbox") {
inputs[i].onclick = function () {
var cbs = inputs;
for (var i = 0; i < cbs.length; i++) {
if (cbs[i].type == "checkbox" && cbs[i] != this && this.checked) {
cbs[i].checked = false;
}
}
}
}
}
}
