jquery - 对话框淡出然后又重新出现是什么意思？

Question

我的页面显示我的文件夹中的图像，并允许通过 PHP 删除图像。我想显示删除任何图像的警报。

当您在警报中单击“否”时，它会淡出然后立即再次淡入。为什么会这样？

在示例中，单击任何图像并单击警告框中的“否”以查看我的问题。

$(document).ready(function() {
  $('.dele').each(function(i) {
    var $this = $(this);
    var newClass = "a" + i++;
    $this.addClass(newClass);
  });

  $('.alert').each(function(i) {
    var $jis = $(this);
    var jewClass = "b" + i++;
    $jis.addClass(jewClass);
    var hala = $jis.addClass(jewClass);
  });

  $(".dele").click(function() {
    $(this).children(".alert").fadeIn();
  });

  $("li.no, .alertclose").click(function() {
    $(".alert").fadeOut();
  });
});

body {
  margin: 20px;
  background-color: #999;
}

div.alert {
  position: fixed;
  top: 50%;
  left: 50%;
  width: 300px;

你能不能用下面的代码替换你的代码......经过测试并为我工作

$('body').on('click','li.no, .alertclose',function() {
    $(".alert").fadeOut();
});
