div mouseenter 和 mouseleave

Question

我有兩個 Div（CSS 是TailwindCss ）

 $(document).on("mouseover", "#imagebox", function() { $("#PictureHoverPanel").removeClass("invisible"); }) $(document).on("mouseout", "#imagebox", function() { $("#PictureHoverPanel").addClass("invisible"); })

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/tailwindcss/2.0.3/tailwind.min.css" integrity="sha512-wl80ucxCRpLkfaCnbM88y4AxnutbGk327762eM9E/rRTvY/ZGAHWMZrYUq66VQBYMIYDFpDdJAOGSLyIPHZ2IQ==" crossorigin="anonymous" /> <div id="PictureHoverPanel" class="invisible absolute flex flex-col justify-center rounded-xl bg-gray-600 opacity-70"> <div class="flex justify-center"> <a class="bg-gray-800 px-2 py-1 text-white border border-red-800 font-semibold cursor-pointer">Remove</a> </div> </div> <img id="imagebox" class="w-48 h-48 rounded-xl md:w-64 md:h-64" src="https://picsum.photos/seed/1/100">

問題是當我輸入#imagebox ，每次鼠標移動都會觸發mouseout事件，從而導致快速閃爍。 如何確保不添加invisible的 class 除非 cursor 完全超出imagebox

您也可以將#PictureHoverPanel添加到事件偵聽器中。

像這樣：

$(document).on("mouseover", "#imagebox, #PictureHoverPanel", function() {
  $("#PictureHoverPanel").removeClass("invisible");
})

 $(document).on("mouseover", "#imagebox, #PictureHoverPanel", function() { $("#PictureHoverPanel").removeClass("invisible"); }) $(document).on("mouseout", "#imagebox, #PictureHoverPanel", function() { $("#PictureHoverPanel").addClass("invisible"); })
