javascript - 单击事件后，jQuery slideDown() 函数对两个元素均不起作用

Question

我想使用 slideDown() 函数制作动画，但不知何故，.quote-container 不包含在其中，即使 slideDown() 函数包含 .quote-container 和 #new-quote 元素。

为什么它们在第一个加载动画中有效，而在第二个加载动画中(在点击事件之后)却没有(只有 #new-quote 有效)？ .quote-container 仅在 slideDown() 动画结束后显示，即 2 秒。

// slideDown() works only for #new-quote
$("#new-quote").on("click", function() {
  $(".quote-container, #new-quote").slideUp(2000, function() {
    $(".quote-container, #new-quote")
      .css("display", "inline-block")
      .hide();

    $(".quote-container, #new-quote").slideDown(2000);
  });
});

// slideDown() for both elements works
var height = $(".quote-container").outerHeight();
$(".quote-container, #new-quote")
  .css("display", "inline-block")
  .hide();
$("#new-quote").css("height", height + 80);
$(".quote-container").css("padding", "2.5rem");
$(".quote-container, #new-quote").slideDown(2000);

问题已修复:

我需要从 onclick 中删除 $(".quote-container, #new-quote").css("display", "inline-block").hide(); 行事件:

$("#new-quote").on("click", function() {
  $(".quote-container, #new-quote").slideUp(2000, function() {
    $(".quote-container, #new-quote").slideDown(2000);
  });
});
