我正在尝试从W3C显示python例外的模态框示例，异常字符串非常长，并且模态框体无法在一个屏幕中显示所有这些，并且模态页脚不能也显示（浏览器滚动条不会向下滚动），虽然为整个模态设置overflow: auto;，代码就像，
function show_modal(row, column) {
var err;
var modal_header = $(".modal-header h2");
modal_header.text("header_txt");
var modal_body = $(".modal-body p");
// clear any previous contents
modal_body.text("");
var $pre = $("<pre>").html(err);
modal_body.append($pre);
var modal_footer = $(".modal-footer h3");
modal_footer.text("footer_txt");
modal.style.display = "block";
}.modal {
display: none;

错误消息太长而无法放入编辑器中，因此就像

那么如何正确添加滚动条以在模态体中显示内容，并在向下滚动页面时显示模态页脚。
