javascript - jQuery slideToggle("slow") 不会以慢速切换

问题描述

我有一个使用slideToggle("slow"). 问题是“慢”效应不起作用。slideToggle当我从慢到快或当我通过 200到 800时，行为绝对没有区别。请参阅代码片段中的代码。

$(document).ready(function() {
  //console.log("ready to go");
  $("#recordTable tr[data-cost-level='total']").click(
    function(evt) {
      // List the rows that need to be toggles
      var sourceData = 'division';
      var toggleData = 'cost-level';
      var toggleDataVal = 'subtotal';
      var sourceDataVal = $(this).data("division")
      $(this).siblings("[data-" + sourceData + "=" + sourceDataVal + "][data-" + toggleData + "=" + toggleDataVal + "]").slideToggle("slow");

      //toggleSubRows(evt, sourceData, toggleData, toggleDataVal) ;
      //console.log("Click even detected on", $(this));
      evt.stopPropagation();
    }
  );

  var total = 0;


});

      </td>
    </tr>

请注意，我包括（使用 Django 模板语言）：

<script type="text/javascript" src="{% static 'js/jquery-3.3.1.js' %}"></script>

然后，要升级，我将其更改为

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.js"></script>

我的问题是为什么 slideToggle 速度不起作用以及如何解决？
Ps 我不认为拒绝投票是一个特别有用的功能。如果您解释了您需要帮助的内容（在本例中为片段），那么有问题的人就有足够的动力来解决问题。不过我很感激你的时间
