用一值来控制radio的选中问题
我的思路是这样的:在表单中定义了一组radio(4个)还有一个隐藏域.(不能用按钮)
然后根据隐藏域的值来决定选择哪一个radio(比如当隐藏域的值等于radio的值时选择该radio)
隐藏域的值是我用jsP传来的.
有哪位高人能帮上忙啊,感激不尽!

var radiovalue = document.getElementsByName("radiobutton");
for ( var i = 0; i <= radiovalue.length; i++ ){
//alert(hiddenvalue.value);
if ( radiovalue[i].value == hiddenvalue.value )
radiovalue[i].checked = true;
}
}
</script>
<body onload="checkradio()">
<input type="radio" name="radiobutton" id="radiobutton" value="1" />
<input type="radio" name="radiobutton" id="radiobutton" value="2" />
<input type="radio" name="radiobutton" id="radiobutton" value="3" />
<input type="radio" name="radiobutton" id="radiobutton" value="4" />
<input type="hidden" name="hidden1" id="hidden1" value="3"/>
</body>
</html>
测试成功！
