Radio的使用,获取Radio的所选的值(Checkbox的使用与之类似)
<html xmlns="http://www.w3.org/1999/xhtml" ><head runat="server"> <title>无标题页</title>
<script type="text/javascript">...
function ShowSexSelect()
...{ var Sex; for(var i = 0; i < document.all.sex.length; i++) ...{ if (document.all.sex[i].checked == true)...{ Sex=document.all.sex[i].value;}
} alert(Sex);
}</script></head><body> <form id="form1" runat="server"> <div><table border="0" cellpadding="0" cellspacing="2" width="800px"> <tr> <td id="td_Sex">性别：<input id="rdoMen" name="sex" type="radio" checked="checked" value="男" />男 <input id="rdoWomen" name="sex" type="radio" value="女"/>女</td> </tr><tr> <td><input id="Button1" type="button" value="ShowSexSelect" onclick="ShowSexSelect();"/></td></tr></table> <div> </form></body></html>要注意的是:Radio的name的值一定要一致,这样它们才是一组!
