I think your best bet is to track mouseoverat the documentlevel and maintain the id of the last element hit.
我认为最好的方法是跟踪mouseover的document水平，并保持最后一个元素命中的ID。
var lastID = null;
var handleMouseover = function (e) {
var target = e.target || e.srcElement;
lastID = target.id;
};
if (document.addEventListener) {
document.addEventListener('mouseover', handleMouseover, false);
}
else {
document.attachEvent('onmouseover', handleMouseover);
}

You can use a javascript variable to store the current hovered div.. jQuery (or standard JS) could be used to set the event handler to populate the variable.
您可以使用 javascript 变量来存储当前悬停的 div .. jQuery（或标准 JS）可用于设置事件处理程序以填充变量。
