<form  name=mxh3>
<div id=mxh1 style="position:absolute;visibility: hidden"><input value="dtest" type="text"></div>
<div id=mxh2 style="position:absolute;visibility: hidden"><input value="d" type="text"></div>
<!--<input  name=aa  type=radio  onclick="document.all.mxh2.style.visibility='visible'">显示--><br><br>
<input  name=aa  type=radio  onclick="change()">显示
<input  name=aa  type=radio  onclick="change1()">隐藏
<!--<input  name=aa  type=radio  onclick="document.all.mxh2.style.visibility='hidden'">隐藏-->
