I am trying to achieve a functionality where if a user selects a certain option from a dropdown list, it will hide or display specific items in a radio button list. For example, if the user chooses "Opt2" from ddlTest, I want to hide rblItem3. Can someone please guide me on how to accomplish this using JavaScript?
<table>
<tr>
<td>
<asp:RadioButtonList ID="radiobuttonlist1" runat="Server" RepeatLayout="flow" RepeatDirection="horizontal">
<asp:ListItem Text="Radio 1" Value="1" Selected="True"></asp:ListItem>
<asp:ListItem Text="Radio 2" Value="2"></asp:ListItem>
<asp:ListItem Text="Radio 3" Value="3"></asp:ListItem>
</asp:RadioButtonList>
</td>
<td>
<input type="button" value="Submit" onclick="GetRadioButtonValue('<%= radiobuttonlist1.ClientID %>')" />
</td>
</tr>
</table>
Javascript Code:-
<script language="javascript" type="text/javascript">
// Function to retrieve selected radio button value
function GetRadioButtonValue(id)
{
var radioGroup = document.getElementsByName(id);
for (var i = 0; i < radioGroup.length; i++)
{
if (radioGroup[i].checked)
// Hide the item if checked
}
}
</script>
