jquery - 如何编写 jQuery 来禁用从单选按钮列表中选择项目时的下拉菜单

Question

我有这段代码，但它不适用于具有母版页和ajax控制工具包的asp.net页面(我已经包含了ToolScriptManager)。代码是

<script type="text/javascript">
    jQuery(function() {


        $("#<%=RadioButtonList1.ClientID%>").change(function() {
            var rbvalue = $("input[@name=<%=RadioButtonList1.UniqueID%>]:radio:checked").val();
            if (rbvalue == "No") {
                $("#DropDownList1").attr("disabled", false);
            }
            else if (rbvalue == "Yes") {
                $("#DropDownList1").attr("disabled", true);
            }
        });
    });
</script>

<script type="text/javascript">
    $(document).ready(function() {

        $('#RadioButtonList1').change(function() {
            var rbvalue = $('#RadioButtonList1').val();
            if (rbvalue == "No") {
                $('#DropDownList1').attr('disabled', false);
            }
            else if (rbvalue == "Yes") {
                $('#DropDownList1').attr('disabled', true);
            }
        });
    });
</script>
