我有以下的JavaScript函數:用JavaScript功能驗證
function validateLocality(object, args) {
if (document.getElementById("<%=ddlLocality.ClientID %>").value == "0") {
args.IsValid = false;
}
else {
args.IsValid = true;
}
}
,並驗證以下下拉列表:
<asp:DropDownList
ID="ddlLocality"
runat="server"
DataSourceID="DataSourceListTowns"
DataTextField="town_name"
DataValueField="town_id"
ToolTip="The Locality Where the User Lives"
AppendDataBoundItems="True"
ViewStateMode="Disabled">
<asp:ListItem Value="0">Select Locality</asp:ListItem></asp:DropDownList>
<asp:CustomValidator
runat="server"
ControlToValidate="ddlLocality"
ErrorMessage="Select Locality"
ToolTip="Select Locality"
ID="validateLocality"
ClientValidationFunction="validateLocality()">*</asp:CustomValidator>
的事情是它不驗證下拉可言。
感謝任何幫助因爲我破壞了我對這個
我現在感覺很愚蠢:/ – 2012-04-28 13:17:05
