jquery - Bootstrap Multiselect 滚动条拖动在 Bootstrap Modal 中不起作用

Question

我正在尝试在 Bootstrap 模式中使用 Bootstrap 多选。我能够初始化它并完美地渲染它，没有任何问题。我面临一个非常烦人的问题，当我尝试将滚动条拖动到模态框内时，下拉菜单会关闭。我尝试并在 Bootstrap 模式之外复制了相同的代码，它工作得很好。我创建了 jsFiddle 来演示这个问题。

正常滚动效果很好，但在模式中拖动滚动条会关闭下拉菜单。有什么办法可以解决这个问题？

这是您的解决方案:

$('.modal').on('mousedown mouseup click', '.multiselect-container', function(e) {
    e.preventDefault();
});
