我只是想问我如何选择我的单选按钮列表的值，这里是我的代码。
function CheckRadioButton(rdbRemarks){
document.getElementByID(rdbRemarks).SelectedValue = "1";
}
Here is the code of my button onclick
这是我的按钮 onclick 的代码
<asp:Button ID="CheckRadioButton" CssClass="ButtonCalibri" Width="80px" runat="server" Text="Save" onclick="CheckRadioButton('<%=rdbRemarks.ClientID%>')" />
Here is the code of my radiobuttonlist in case you need a reference
这是我的单选按钮列表的代码，以防您需要参考
<asp:RadioButtonList ID="rdbRemarks" CssClass="LabelCalibri" runat="server" onselectedindexchanged="rdbRemarks_SelectedIndexChanged">
<asp:ListItem Value="1" Text="Charge to Utilization"></asp:ListItem>
<asp:ListItem Value="2" Text="Charge to Operating Expense"></asp:ListItem>

我想要的是当我单击按钮时，将选择列表中的一个单选按钮，例如选定的值为“1”，第一个单选按钮将被选择。我目前不知道该怎么做，请帮助我解决这个问题。
