单选钮控制文本框

[yuanhua123]

请问
<input type="radio" name="typestate" value="0">国际
<input type="radio" name="typestate" value="1" checked>国内
当我选择国际时 显示一个文本框填写，但我选择国内是，出现一个下拉菜单选择省会。选择其一时，其二就隐藏了。 请问大虾们怎么写js

分少了点，你写两个掩藏了的控件就可以了

<div>


<input type="radio" name="t" value="0" onclick="arg()">国际

<input id="u" style="display:none"> <p>



<input type="radio" name="t" value="1" onclick="arg()" checked>国内

<select id="g">
<option value="">请选择</option>
</select>

<div>


<script language="JavaScript">

var arg = function (){

if (t[0].checked)
{
u.style.display = "" ;

g.style.display = "none" ;
}
else
{
u.style.display = "none" ;

g.style.display = "" ;
}


}

</script>

还可以这样:

<div>


<input type="radio" name="t" value="0" onclick="arg(this.checked,u,g)">国际

<input id="u" style="display:none"> <p>



<input type="radio" name="t" value="1" onclick="arg(this.checked,g,u)" checked>国内

<select id="g">
<option value="">请选择</option>
</select>

<div>


<script language="JavaScript">

var arg = function (tc , u_obj , g_obj){

if (tc)
{
u_obj.style.display = "" ;

g_obj.style.display = "none" ;
}

}

</script>

这样也行:
<div>


<input type="radio" name="t" value="0" onclick="u.style.display = '';g.style.display = 'none'">国际

<input id="u" style="display:none"> <p>



<input type="radio" name="t" value="1" onclick="g.style.display = '';u.style.display = 'none'" checked>国内

<select id="g">
<option value="">请选择</option>
</select>

<div>

查查 Style.display

[rjzou2006]

style.display="none" or "block"

or

style.visibility='visible" or"hidden"
