Question

有2个RadioButtonLists：

Are you a minor?:  oYes  oNo
Do you wish a joint account?:  oYes  oNo

如果第一个问题的答案是肯定的，我想检测对第一个问题的回答，并使用jQuery函数将第二个问题的答案设置为yes。提前谢谢。

<asp:Label ID="lblMinfor" CssClass="boldIt" runat="server" Text="Is this account for a minor" Style="float: left; width: 200px;"></asp:Label><br />
<asp:RadioButtonList ID="rdlMinor" runat="server" RepeatDirection="Horizontal" Width="130px" Style="float: left;" BorderStyle="None" RepeatLayout="Flow" ()>
    <asp:ListItem>Yes</asp:ListItem>
    <asp:ListItem Selected="True">No</asp:ListItem>
</asp:RadioButtonList>
<asp:Label ID="lblJoint" CssClass="boldIt" runat="server" Text="Is this for a joint account?" Style="float: left; width: 200px;"></asp:Label><br />
<asp:RadioButtonList ID="rdlJoint" runat="server" RepeatDirection="Horizontal" Width="130px" Style="float: left;" BorderStyle="None" RepeatLayout="Flow">
    <asp:ListItem>Yes</asp:ListItem>
    <asp:ListItem Selected="True">No</asp:ListItem>
</asp:RadioButtonList>

Answer 1

$('#<%=rdlMinor.ClientID %>').change(function() {
    if($('#<%=rdlMinor.ClientID %> input:checked').val() == 'Yes') 
    {
        $('#<%=rdlJoint.ClientID %>').find("input[value='Yes']").attr("checked", "checked");
    }
});

Answer 2

试试这段代码：

<script type="text/javascript">

$(document).ready(function() {

    $("#<%=rdlMinor.ClientID%>").change(function()
    {
        var rbvalue = $("input[@name=<%=rdlMinor.ClientID%>]:radio:checked").val();

        if(rbvalue == "Yes")
        {
            $('#<%=rdlJoint.ClientID %>').find("input[value='Yes']").attr("checked", "checked");
        }
    });

});

</script>
