asp源码单选框想让默认选中一个

<tr>
<td class="td_1"><%=viewType%></td><td class="td_2"> <% = getList(1,"clientsType","","clientsType","type",""&viewType&"") %>　　　<%=viewstart%>∶<% = getList(1,"clientsstart","","clientsstart","start",""&viewstart&"") %></td>
<td class="td_1"><%=viewSource%></td><td class="td_2"> <% = getList(1,"clientsSource","","clientsSource","Source",""&viewSource&"") %></td>

Answer 1

<form id="form1" name="form1" method="post" action="">
<p>
<label>
<input name="RadioGroup1" type="radio" id="RadioGroup1_0" value="单选1" checked="checked" />
单选1</label>
<br />
<label>
<input type="radio" name="RadioGroup1" value="单选2" id="RadioGroup1_1" />
单选2</label>
<br />
</p>
</form>
这上面就是一个表单单选按钮组（是默认的“单选1”选项，代码为：checked="checked"是选中的意思）
