无法使用 javascript 使窗口淡入淡出或在 css 中添加过渡效果

我一直在使用该fadeOut功能时遇到问题,以便在关闭窗口弹出消息时添加效果。

同时,我尝试过在CSS中给div添加过渡效果,但也没有成功。我的想法是在 JavaScript 部分的语句中添加这种淡入淡出效果if,但这不起作用。

<body>

  <div class="container">

    <div class="window" id="win">

      <div class="layover">

        <div class="h2">

          <h2>Oops!</h2>

        </div>

        <div class="yesandno">

          <figure class="yes">

            <button onclick="window.location.href= 'espanol.html';">Si</button>

          </figure>

          <figure class="no">

            <button onclick id="buttonn">No</button>

          </figure>

        </div>

        <div class="langmessage">

          Hemos detectado que el idioma de su ordenador se encuentra en español. ¿Le gustaría utilizar la versión en español de nuestro sitio web?

        </div>

      </div>

    </div>

  </div>


  <script type="text/javascript">

    var lang = navigator.language;

    if ("" + lang == "es-US") {

      var div = document.getElementById("win");

    }

    var button = document.getElementById("buttonn")

    buttonn.onclick = function() {

      var div = document.getElementById("win");

      if (div.style.display !== "none") {

        div.style.display = "none";


      }

    }

  </script>


</body>

为了使用该fadeOut()方法,您必须将其包含jQuery到您的项目中,但您也可以使用纯 JavaScript 手动对其进行编程。下面是两种解决方案,一种使用普通的jQuery,另一种使用普通的javascript。jQuery 解决方案:注意:如果使用jQuery,您可以重写部分代码,例如document.getElementById("win")等$("#win"),但这超出了问题的范围。var lang = navigator.language;if ("" + lang == "es-US") {&nbsp; var div = document.getElementById("win");}var buttonn = document.getElementById("buttonn");buttonn.onclick = function() {&nbsp; var div = document.getElementById("win");&nbsp; if (div.style.display !== "none") {&nbsp;
