javascript - jQuery hide() 无法获取要识别的 'duration' 设置

Question

似乎找不到这个问题的答案。

我正在尝试为 hide() 制作动画隐藏 <li> 时元素。我有一个 <span>在<li>里面用作“删除”按钮。

这是我似乎无法开始工作的部分。

$('#list1').on('click', 'li span', function(event) {  
  $(this).parent().hide(1000); 
});

列表项是，实际上是隐藏的。但是，持续时间并未生效。该元素在没有任何“动画”的情况下消失。

它正在运行:https://jsfiddle.net/scampione/effnuct0/14/

非常感谢任何帮助。

一旦我包含 jQuery，这里似乎工作正常。

如评论中所述，jQuery Slim 不包含您正在使用的动画。您需要包含完整的 jQuery 库。

var buildArray = function(max) {
  var rtnArray = [];
  var i = 0;
  for (i = 1; i <= max; i++) {
    rtnArray.push(i);
  }
  return rtnArray;
}

var feedBack = $('.display-feedback');

var delButton = '<span class="delete-item">X</span>';

var appendToList = function(theStr) {
  var target = $('#list1')
  target.append('<li>' + theStr + delButton + '</li>')
}


$('.clear-feedback').on('click', function() {
  feedBack.empty();
});

$('#list1').on('click', 'li span', function(event) {
  $(this).parent().hide(1000);
});

$('#list1').on('click', 'li', function(event) {
  feedBack.text(event.type + " - " + event.target.nodeName + " - " + event.currentTarget);
});

var myArray = buildArray(10);
appendToList(myArray)
appendToList(myArray.map(num => num * 7));
appendToList(myArray.filter(num => num > 5));
appendToList(myArray.map(num => num * 7).filter(num => num > 35));
