Question

我想动态添加引导警报，效果为fadeIn，fadeOut效果关闭，我试过：

function alert(title, text, type) {
  var html = $("<div class='alert alert-dismissible hide fade " + type + "'><strong>" + title + "</strong> " + text + "<a href='#' class='close float-close' data-dismiss='alert' aria-label='close'>×</a></div>");
  $('body').append(html);
  html.addClass('in show');
}


$('#EMail').click(function() {
  alert('Error!', 'Your Email is not valid', 'alert-danger');
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-WskhaSGFgHYWDcbwN70/dfYBj47jz9qbsMId/iRN3ewGhXQFZCSftd1LZCfmhktB" crossorigin="anonymous">

<input type="text" id="EMail" />

使用此功能，成功关闭工作但附加fadeIn效果不起作用。如何在fadeIn效果的文档中附加Bootstrap警报？

请注意，我不需要jQuery fadeIn或fadeOut我只想使用标准引导程序class执行此操作fade + in或out

使用setTimeout

更新了函数

function alert(title, text, type) {
  var html = $("<div class='alert alert-dismissible hide fade in " + type + "'><strong>" + title + "</strong> " + text + "<a href='#' class='close float-close' data-dismiss='alert' aria-label='close'>×</a></div>");
  $('body').append(html);
  setTimeout(function() {
 html.addClass('show');
  },0);
}


$('#EMail').click(function() {
  alert('Error!', 'Your Email is not valid', 'alert-danger');
});

Bootstrap警报附加和淡入/淡出
