Answer 1

格式问题。js不能象vbs那样写else if,改成这样：
<script type="text/javascript">
function target(id){
if(id==0){
document.getElementById('password').style.display="block";
}
else{
if(id==1){
document.getElementById('password').style.display="none";
}
}
}
</script>
<input name="photoclass" type="radio" value="0" checked="checked" id="photoclass" onclick="target(1);" /><label
for="photoclass"><em>公开</em></label>
<input name="photoclass" type="radio" value="1" id="photoclass1" onclick="target(0);" /><label
for="photoclass1"><em>私密</em></label>
<div id="password"> aaaaaaaaaaaaaaaaaaaaaaaaaaaa</div>

Answer 2

我拿下来给你运行了一下，代码都没问题，就是你这句：
document.getElementById('password').style.display="block";
那个ID为password的元素不存在，呵呵，你随便加个div把它的ID设为password就没问题了

参数要用引号括起来???
