Question

我正在使用jquery和c＃动态地将radiobuttonlist listitem设置为selected。我想创建一个重置类型按钮，将radiobuttonlist所选项目重置回列表中的第一项。

jQuery / jsTree函数当前正在重置文本框和隐藏字段：

$('#ContentPlaceHolder1_hfNodeID').val('');
$('.txtPage').val('');
$('.rblContentTypesGetAll').val();
$('.contentPageForm').show(),

.rblContentTypesGetAll是我要重置的radiobuttonlist（或选择最顶级的listitem）。

表单的HTML：

 <asp:Panel ID="PagesForm" CssClass="contentPageForm" runat="server">
 <asp:HiddenField ID="hfNodeID" runat="server" Value="" />
 <table>
     <tr>
        <td>Page</td>
        <td><asp:TextBox ID="txtPage" CssClass="txtPage" runat="server" /><span class="validate">*</span><br />
        <asp:RequiredFieldValidator ID="rfvPage" runat="server" CssClass="validate" ControlToValidate="txtPage" Display="Dynamic" ErrorMessage="Page Name Required" ValidationGroup="page" /></td>
    </tr>
    <tr>
        <td>Content Type</td>
        <td>
            <asp:RadioButtonList id="rblContentTypesGetAll" CssClass="rblContentTypesGetAll" OnLoad="rblContentTypesGetAll_Load"  runat="server" >
            </asp:RadioButtonList>
        </td>
    </tr>
    <tr>
        <td> <asp:Button ID="Submit" runat="server" OnClick="PageSubmit_Click" Text="Save" ValidationGroup="page" />
             <asp:Button ID="Cancel" runat="server" OnClick="Cancel_Click" Text="Cancel" />
        </td>
    </tr>
 </table>
 </asp:Panel>

Answer 1

$('#rblContentTypesGetAll_0').attr('checked', 'checked');

修改

Bry4n说以下为他效劳：

$("#ContentPlaceHolder1_rblContentTypesGetAll_0").attr("checked", "checked");

Answer 2

您是否错过了val的参数？

$('.rblContentTypesGetAll').val('');

将RadioButtonList First ListItem设置为Selected
