触发事件？？
我有3个复选框，一个输入框，
<input type= "radio " name= "1 " value= "1 " >
<input type= "radio " name= "a " value= "2 " >
<input type= "radio " name= "a " value= "3 "checked>
<input name= "b " >
我点击输入框，那3个复选框就隐藏，如何实现
[解决办法]
<script language= "JavaScript " type= "text/javascript ">
<!--
function dis()
{
if (document.getElementById( "rd ").style.display== " ")
{
document.getElementById( "rd ").style.display = "none ";
}
else
{
document.getElementById( "rd ").style.display = " ";
}
}
//-->
</script>
</head>
<body>
<span id= "rd " style= "display: ">
<input type= "radio " name= "1 " value= "1 " >
<input type= "radio " name= "a " value= "2 " >
<input type= "radio " name= "a " value= "3 "checked>
</span>
<input name= "b " onclick= "dis(); ">
</body>
