javascript中如何得到radio的值？？

[zhangzgsky]

<form name="form1">
<input type="radio" name="transtyle" value="电话" >电话
<input type="radio" name="transtyle" value="传真" >传真
<input type="radio" name="transtyle" value="email">email
<input type="radio" name="transtyle" value="邮寄">邮寄
<input type="radio" name="transtyle" value="自取">自取

</form>
document.form1.transtyle.value
我这样怎么得不到所选择出来的radio值？？？

lsrzm(月影飞鸿--我要分、分、分.....) 说得很对


to zhangzgsky (忧伤的紫雨) :

你首先应当想到，name属性一样的话，就是一个数组
所以：
aa = document.getElementsByName("transtyle");
实际上等价于
aa = document.all.transtyle
