问题
我有一个在线商店的购物车，并且可以在导航菜单中查看悬停在div上的购物袋的内容。我创建了一个原型，其中shoppingTab div实际上触及了导航栏中的trolley div，使其在悬停时出现。这样我就可以将光标从导航栏中的shoppingTab div移动到trolley div，而购物车不会消失，直到onmouseout奇怪地设置为shoppingTab在导航栏中，不是trolley div本身，但我喜欢这个奇怪的小怪癖。因此，我想将此行为复制到我的新网站上。
原型代码
以下是JSFiddle上的原型（并且它不起作用onmouseover ???）https://jsfiddle.net/Please_Reply/k1k566wp/1/所以以下是原始代码，如果你复制并粘贴它将起作用到一个空白的HTML文件等。

我的当前代码
我有一个当前代码的JSFiddle（它没有工作，所以我也复制了下面的代码。我认为这是因为我在那里有纯Javascript它试图读作JQuery ???我不知道......无论如何，如果你不能修复JSFiddle，只需复制实际在JSFiddle链接下工作的代码）...... https://jsfiddle.net/Please_Reply/9uwj2bed/2/
所以基本上，在下面的代码中，当您将鼠标悬停在shoppingCart div（可能使用shopcartbar）上时，我需要显示onmouseover div。但就onmouseout而言，我希望能够悬停在shoppingCart div而不会消失。我希望onmouseout同时处理shopcartbar div和shoppingCart div，就像我的原型中的某种方式一样???
我在onmouseover div上使用shoppingCart时的另一个问题是，当我将鼠标悬停在.smallProduct div内的任何shoppingCart div上时，它们似乎触发onmouseout这也不是我想要的，它们是shoppingCart div的一部分。

答案 0 :(得分：0)
尝试替换此部分：
function tabDisplay(displayStatus){
shoppingTab.style.display = displayStatus;
}
有了这个：
$( "#shopcartbar, #shoppingTab" ).mouseenter(function() {
$("#shoppingTab").show();
})
.mouseleave(function() {
$("#shoppingTab").hide();
});
