Question

我在页面上有两个radiobuttonlist和一个checkboxlist。理想情况下，基于复选框选择的值，我想使用jquery函数启用/禁用相应的radibuttonlist。

但有些$（“input [name * =”+ columnName +“]”）总是返回null。它的名字找不到radiobuttonlist？

    $(function() {
        function checkBoxClicked() {

            var isChecked = $(this).is(":checked");
            var columnName = "rblColumn" + $(this).parent().attr("alt");

            if (isChecked) {
                $("input[name*=" + columnName + "]").removeAttr("disabled");
            } else {
                $("input[name*=" + columnName + "]").attr("disabled", "disabled");

                $("input[name*=" + columnName + "] input").each(function() {
                    $(this).attr("checked", "")
                });

            }

        }

        //intercept any check box click event inside the #list Div
        $(":checkbox").click(checkBoxClicked);
    });




<asp:Panel ID="TestPanel" runat="server">
<asp:CheckBoxList ID = "chkColumn" runat="server" RepeatDirection="Horizontal">
    <asp:ListItem id = "Column1" runat="server" Text="Column 1" Value="1" alt="1" class="HeadColumn" />
    <asp:ListItem id = "Column2" runat="server" Text="Column 2" Value="2" alt="2" class="HeadColumn"/>
</asp:CheckBoxList>

<table>
    <tr>
        <td>
            <asp:RadioButtonList ID = "rblColumn1" runat="server" RepeatDirection="Vertical" disabled="disabled">
                <asp:ListItem id="liColumn1p" runat="server" />
                <asp:ListItem id="liColumn1n" runat="server" />
            </asp:RadioButtonList>
        </td>
        <td>
            <asp:RadioButtonList ID = "rblColumn2" runat="server" RepeatDirection="Vertical" disabled="disabled">

            </asp:RadioButtonList>
        </td>
    </tr>
</table>
</asp:Panel>

<div id="TestPanel">

<table id="chkColumn" border="0">
        <tr>
            <td><span id="Column1" alt="1" class="HeadColumn"><input id="chkColumn_0" type="checkbox" name="chkColumn$0" /><label for="chkColumn_0">Column 1</label></span></td><td><span id="Column2" alt="2" class="HeadColumn"><input id="chkColumn_1" type="checkbox" name="chkColumn$1" /><label for="chkColumn_1">Column 2</label></span></td>
        </tr>
    </table>

Answer 1

我明白了。我在每个radiobutonlist中添加了cssclass并通过id：

找到它

$（“。myRadioButtonList [id * =”+ columnName +“]”）。removeAttr（“disabled”）;

现在正在运作。谢谢，帕特里克。你提醒我有关id / name滥用的信息。

Answer 2

为我工作（jQuery）：

$('[name*="' + columnName + '"]');

jquery动态地通过名称获取radiobuttonlist
