javascript - 在不同宽度的可排序 div 中使用 amchart

Question

我有一个用 bootstrap 制作的页面，我在这个页面中有 2 个不同的部分，第一个使用“col-lg-12”，第二个使用“col-lg-6”，它们都是可拖动的。我想在其中放置一些 amcharts，一切正常，我的图表响应迅速，但是当我将大部分中的 div 移动到小部分图表时，图表响应功能停止工作并且不会自动调整大小。我的 html 代码

我不清楚究竟是什么阻止了图表调整大小。

当您开始拖动大 div 时，图表父级的父级 div (.kt-portlet) 得到 display: none;。停止拖动后，它会设置回 flexbox 并且图表不再自动调整大小(尝试通过 devtools 手动更新 #kt_chart1 的宽度)。

但是，如果您手动将图表 div 的父级 (.kt-portlet__body) 或父级的父级的显示模式重置为 display: block;，则删除不久之后，图表可以再次自动调整大小。

因此，希望不会触发样式不正确的内容的不希望的闪现，使它再次工作的一种骇人听闻的方法是在 stop event of the slider 之后的短时间内执行上述操作。 :

            stop: function(event, ui) {
              setTimeout(function() {
                ui.item.css('display', 'block');
              }, 10);
              setTimeout(function() {
                ui.item.css('display', '');
              }, 20);
            },
