寫Javascript來判斷是否有對RadioButtonList選項選擇,效果如下:

準備好RadioButtonList數(shù)據(jù)源:
Cosmetic.vb
復制代碼 代碼如下:

Imports Microsoft.VisualBasic
Namespace Insus.NET
Public Class Cosmetic
Private _ID As Integer
Private _Type As String
Private _Name As String
Private _Weight As Decimal
Private _UM As String
Public Property ID As Integer
Get
Return _ID
End Get
Set(value As Integer)
_ID = value
End Set
End Property
Public Property Type As String
Get
Return _Type
End Get
Set(value As String)
_Type = value
End Set
End Property
Public Property Name As String
Get
Return _Name
End Get
Set(value As String)
_Name = value
End Set
End Property
Public Property Weight As Decimal
Get
Return _Weight
End Get
Set(value As Decimal)
_Weight = value
End Set
End Property
Public Property UM As String
Get
Return _UM
End Get
Set(value As String)
_UM = value
End Set
End Property
Public Sub New()
End Sub
Public Sub New(id As Integer, type As String, name As String, weight As Decimal, um As String)
Me._ID = id
Me._Type = type
Me._Name = name
Me._Weight = weight
Me._UM = um
End Sub
Public Function GetData() As List(Of Cosmetic)
Dim o As New List(Of Cosmetic)
Dim c As New Cosmetic(1, "滋潤霜", "玉蘭油", 50, "g")
o.Add(c)
Dim c1 As New Cosmetic(2, "滋潤霜", "雅詩蘭黛", 100, "g")
o.Add(c1)
Dim c2 As New Cosmetic(3, "滋潤霜", " 蘭蔻", 80, "g")
o.Add(c2)
Dim c3 As New Cosmetic(4, "滋潤霜", "歐萊雅", 60, "g")
o.Add(c3)
Dim c4 As New Cosmetic(5, "滋潤霜", "芭比波朗", 120, "g")
o.Add(c4)
Return o
End Function
End Class

End Namespace

在aspx放一個RadioButtonList控件和一個銨鈕:
復制代碼 代碼如下:

化妝品:asp:RadioButtonList ID="RadioButtonListCosmetic" runat="server" RepeatColumns="10" RepeatDirection="Horizontal">/asp:RadioButtonList>
br />
asp:Button ID="Button1" runat="server" Text="Select" />

在aspx.vb中,為RadioButtonList綁定數(shù)據(jù)源,當然綁定數(shù)據(jù)源下面的代碼中,還得引用命名空間 Imports Insus.NET
復制代碼 代碼如下:

Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
If Not IsPostBack Then
Data_Binding()
End If
End Sub
Private Sub Data_Binding()
Dim objCosmetic As New Cosmetic()
Me.RadioButtonListCosmetic.DataSource = objCosmetic.GetData()
Me.RadioButtonListCosmetic.DataTextField = "Name"
Me.RadioButtonListCosmetic.DataValueField = "ID"
Me.RadioButtonListCosmetic.DataBind()
End Sub

接下來是演示開始,寫Javascript代碼:
復制代碼 代碼如下:

View Code
script type="text/javascript">
function CheckIsSelected() {
var rbl = document.getElementById("%=RadioButtonListCosmetic.ClientID%>");
var radio = rbl.getElementsByTagName("input");
var isSelect = false;
for (var i = 0; i radio.length; i++) {
if (radio[i].checked) {
isSelect = true;
break;
}
}
if (!isSelect) {
alert("請選擇一個選項。");
}
return isSelect;
}
/script>

最后是為銨鈕Button寫客戶端事件
復制代碼 代碼如下:

asp:Button ID="Button1" runat="server" Text="Select" OnClientClick="return CheckIsSelected()" />
