javascript - 打开时切换对话框 "modal"属性

Question

因此，当对话框已打开并隐藏对话框后面的覆盖层时，我需要将模式设置为 false。这是我尝试过的，

当我打开对话框时，我有一组函数可以查询日历上的拖放事件(如果它是多个事件)，那么我需要使对话框不是模态的，并允许与日历进一步交互以移动另一个事件。 .然后验证。

$(this).dialog("option", "modal", false);

当我使用它时，它不会使对话框的覆盖层隐藏。我有什么明显的错误吗？？？

我从开发人员 X 继承了一个使用 jQuery UI 的项目。开发人员 X 没有使用 jQuery UI，而是使用她自己的代码使对话框看起来是“模态的”。她使用了一个“mask”元素，并使用 jQuery.fadeIn 和 jQuery.fadeOut 来切换该元素。你可以做类似的事情来获得你想要的效果。您可以尝试使用一些像这样的 CSS 来开始:

  #mask
  {
      position: absolute; /* important */
      top: 0px; /* start from top */
      left: 0px; /* start from left */
      height: 100%; /* cover the whole page */
      width: 100%;  /* cover the whole page */
      display: none; /* don't show it '*/
      background-color: black;
    }

  .modal_window
  {
      position: absolute; /* important so we can position it on center later */
      display: none; /* don't show it */
      font-weight: bold;
  }
