Question

似乎无法找到答案。

我在隐藏hide()元素时试图为<li>设置动画。我在<span>内部有<li>作为“删除”按钮。

这是我似乎无法工作的部分。

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

列表项 IS ，实际上是隐藏的。但是，持续时间没有生效。该项目正在消失，没有任何“动画”。

感谢任何帮助。

一旦我加入jQuery，似乎在这里工作正常。

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));

隐藏除了速度参数之外，尝试摆脱函数中的li并且只是让它说出span。

jQuery hide（）无法识别'duration'设置
