jquery - 当一个模式关闭并立即打开另一个模式时，如何解决 Bootstrap 4 中的滚动问题？

Question

我的应用程序中有代码需要关闭现有的modal并立即打开另一个modal. 该代码工作正常，但scrolling issue第二个模态有一个（垂直/水平）。如果我调整屏幕大小并尝试垂直滚动，则只有背景内容在滚动。我一直在挖掘问题，这就是我发现的。我认为存在时间竞争条件问题。如果我把这setTime {...some code...,400}将解决问题。我仍然相信有一个更清洁的解决方案。此外，如果有人可以解释为什么会发生这种情况，那就太好了。这是代码示例：

var COMMON_FUNC = {};
COMMON_FUNC.dialogBox = function(title, message, size) {
  title = title || 'HCS System';
  message = message || 'HCS Dialog Box';
  size = size || 'lg';

  var dialog = bootbox.dialog({
    onEscape: true,
    backdrop: true,
    size: size,
    title: '<strong>' + title + '</strong>',
    message: message
  });
  dialog.prop("id", "dialog-box");
};

$("#open-modal-one").on("click", function() {
  var div = '<div><button type="button" class="btn btn-sm btn-secondary edit-record">Edit</button></div>'
  COMMON_FUNC.dialogBox("Modal One", div, "xl");
});

$(document).on("click", ".edit-record", function() {
  $("#dialog-box").modal("hide");
  //setTimeout(function(){$("#second_modal").modal("show");},400);
  $("#second_modal").modal("show");
});

您可以收听hide第一个模式的事件，并且只有在完成后才能显示第二个。

$(document).on("click", ".edit-record", function() {
  $("#dialog-box").one('hidden.bs.modal', function () {
    $("#second_modal").modal("show");
  }).modal("hide");
});

像这样：

var COMMON_FUNC = {};
COMMON_FUNC.dialogBox = function(title, message, size) {
  title = title || 'HCS System';
  message = message || 'HCS Dialog Box';
  size = size || 'lg';

  var dialog = bootbox.dialog({
    onEscape: true,
    backdrop: true,
    size: size,
    title: '<strong>' + title + '</strong>',
    message: message
  });
  dialog.prop("id", "dialog-box");
};

$("#open-modal-one").on("click", function() {
  var div = '<div><button type="button" class="btn btn-sm btn-secondary edit-record">Edit</button></div>'
  COMMON_FUNC.dialogBox("Modal One", div, "xl");
});

$(document).on("click", ".edit-record", function() {
  $("#dialog-box").one('hidden.bs.modal', function () {
    $("#second_modal").modal("show");
  }).modal("hide");
});
