我有一个用bootstrap制成的页面，并且在此页面中有2个不同的部分，第一个使用“ col-lg-12”，第二个使用“ col-lg-6”，两者均可拖动。我想在其中放一些弹药，一切正常，我的图表可以响应，但是当我将div中的一个大部分移动到小部分时，图表响应功能停止工作，并且无法自动调整大小。 我的html代码

答案 0 :(得分：1)
我尚不清楚到底是什么导致图表无法调整大小。
当您开始拖动大div时，图表的父级的父级div（.kt-portlet）将得到display: none;。停止拖动后，它将重新设置为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的父项（.kt-portlet__body）或父项的父项的显示模式重置为display: block;，然后不久将其删除，则图表可以再次自动调整大小。
因此，要使此功能再次正常运行（希望不会引发不正确的样式错误内容闪烁）的一种怪诞方法，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);
},

顺便说一句，这是[y]我们GitHub问题的重复：
