我无法让这段代码工作 - 我想要的是，当我将鼠标悬停在圆圈上时，菜单会出现，然后如果我将鼠标从圆圈或菜单上移开，它就会消失。我尝试做的任何事情都是非常错误的，例如 onmouseover on circle 然后 onmouseout on menu 离开圈子后菜单似乎消失了，我尝试使用除 Divs 以外的其他构造但仍然没有运气，不知所措我决定发布在这里看看是否有人可以提供帮助。请在下面找到代码：
JS：
<script>
function circleAnimOn() {
//show menu
document.getElementById("cssmenuDiv").style.display="block";
document.getElementById("cssmenuDiv").style.visibility="visible";
}
function circleAnimOff() {
//hide menu
document.getElementById("cssmenuDiv").style.display="none";
document.getElementById("cssmenuDiv").style.visibility="hidden";
}
</script>
HTML：
<body>
<div class="divCircle" id="divCircle" onMouseOver="circleAnimOn();">
</div>
<div class="cssmenuDiv" id="cssmenuDiv"><!-- cssmenuDiv -->
<div id='cssmenu'>
<ul>
<li class='active '><a href='index.html'><span>Home</span></a></li>
