jquery - 将 Flexbox 与 jQueryUI 的 sortable 结合使用

我最近一直在做 UI，我非常喜欢使用 Flexbox CSS 来控制布局。我需要一种方法来使我拥有的框可排序和可拖动。

我开始尝试 jQueryUI 的可排序，但它似乎不能很好地与 flexbox 一起工作。 它确实排序了，但我认为它在何时可转换到新位置方面有一些计算错误？要么是这样，要么是我做错了什么。 无论哪种方式，我都会提供我的代码和一个 JSFiddle，这样您就可以亲眼看到其中的怪异之处。我正在寻找的行为是漂亮干净的可放置占位符，并且对齐方式就像 jQueryUI 的示例一样。 要测试单击并拖动图例。也可以尝试将最左边的元素拖动到最右边。

我怎样才能解决这个问题，让它与 Flexbox 一起工作？

JavaScript

    $( "#sortable" ).sortable({
        placeholder: "ui-state-highlight"
    });
    $( "#sortable" ).disableSelection();
});

最佳答案

使用一些 sortable 的事件处理程序来创建一个“幽灵”元素来代替您正在移动的元素。这将有助于保留 flex 计算。

示例:https://jsfiddle.net/CRHain88/vv636vj4/ 

$(document).ready(function() {
  //@JA - Logout Fuction

  // Create a reusable spacer element. I added a background
  // style to give indication that there was once something
  // there. If you're going to style it with more complex
  // design, consider making it have it's own class.
  var placeholderElement = jQuery('<div style="background-color: #eee;"></div>');

  $("#sortable").sortable({
    placeholder: "ui-state-highlight",

    // Add it before the element you're dragging.
    // This assumes that you can only ever drag one element at a time.
    activate: function(event, ui) {
      placeholderElement.insertBefore(ui.item[0]);

      // Explicitly set the height and width to preserve
      // flex calculations
      placeholderElement.width(ui.item[0].offsetWidth);
      placeholderElement.height(ui.item[0].offsetHeight);
    },

    // Remove it when you're done dragging.
    deactivate: function() {
      placeholderElement.remove();
    }
  });

  $("#sortable").disableSelection();
});
