Question

我99％肯定我在这里遗漏了一些非常明显的东西。单击该按钮应使带有.progress类的div可见。不是。

function func() {
  $('.progress').show();
}

Answer 1

@jsnfwlr答案的另一种替代方法是从项目中删除类 d-none ，如下所示：

Answer 2

如果不确定如何通过Bootstrap的d-none或常规display: none隐藏元素，但是无论如何都需要使其可见，只需使用以下代码：

$(el).removeClass("d-none").show();

Answer 3

jquery的显示与bootstrap的d-none不兼容。您可以使用Collapse-https://getbootstrap.com/docs/4.1/components/collapse/-

jQuery show（）不会使Bootstrap d-none类可见
