為了使用該fadeOut()方法，您必須將其包含jQuery到您的項目中，但您也可以使用純 JavaScript 手動對其進行編程。下面是兩種解決方案，一種使用普通的jQuery，另一種使用普通的javascript。
jQuery 解決方案：
注意：如果使用jQuery，您可以重寫部分代碼，例如document.getElementById("win")等$("#win")，但這超出了問題的范圍。
var lang = navigator.language;
if ("" + lang == "es-US") {
var div = document.getElementById("win");
}
var buttonn = document.getElementById("buttonn");
buttonn.onclick = function() {
var div = document.getElementById("win");
if (div.style.display !== "none") {
$("#win").fadeOut();
}
}
