使用Flexbox与jQueryUI的sortable排序功能

4

最近我在做一个 UI,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盒子可以排序和拖动。

我首先尝试了 jQueryUI 的可排序功能,但它似乎在 flexbox 上工作得不太好。它确实可以排序,但是我认为它在新位置中的放置计算上存在一些错误?要么是我做错了什么。无论如何,我将提供我的代码和一个 JSFiddle,这样你就可以看到奇怪的现象了。我想要的行为是漂亮干净的可放置占位符和对齐方式与 jQueryUI 示例相同。测试时请单击图例并拖动。还可以尝试将最左边的项目拖到最右边。

我该如何解决这个问题,以便它可以使用 Flexbox 正常工作呢?

看起来 flexbox 的表现是正常的。一旦元素被拖动,它就会获得绝对位置并打破流程。您可能需要考虑使用具有明确宽度(甚至高度)的包装 div 来保留 flex 尺寸,然后在组件“放置”后进行清理。 - Christian Hain
尝试将最左边的项目抓取到最右边。 - Joseph Astrahan
这是我看到的。具体哪里出了问题?我发现当我拿起元素时,它之前所占据的空间会消失,并且占据了占位符的宽度。然后当我将其放置为第三个项目时,它会换行到下一行。 - Christian Hain
我仍然不清楚如何使其工作,你认为你能修改JSFiddle向我展示一个例子吗? - Joseph Astrahan
诀窍在于在保持 flex-wrap 的同时使其起作用。 - Joseph Astrahan

使用sortable的事件处理程序之一,创建一个“ghost”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();

jQuery sortable可以处理像这样的水平列表,但要激活该行为,它会查找项是否为float: left|right;display: inline;display: table-cell;。以下是jQuery UI 1.12.1中进行检查的位置。

    _isFloating: function( item ) {
        return ( /left|right/ ).test( item.css( "float" ) ) ||
            ( /inline|table-cell/ ).test( item.css( "display" ) );
    },

我在你的代码中使用了 float: left;,现在它表现得更好一些了: https://jsfiddle.net/1s24xpzu/ 这并不是一个完美的解决方案,因为我们基本上只是在欺骗jQuery,可能会产生意想不到的浮动后果。但至少对于我的用例来说,我认为它可以工作。

对于像我一样偶然发现这篇文章的人:

我的使用场景是我想要对一个在 flexbox 行内排序的项目列表进行排序。我尝试了上面的解决方案,但它们没有起作用。我还尝试给第一个元素添加浮动(因为它是被检测到的),但这并没有帮助太多。

相反,我改变了 isFloat 函数(请注意,这应该被称为 isHorizontalSort),像这样:

_isFloating: function( item ) {
        return ( /left|right/ ).test( item.css( "float" )) ||
            ( /inline|table-cell/ ).test( item.css( "display" )) ||
            (
                ( /flex/ ).test( item.parent().css( "display" )) && ( /row|row-reverse/ ).test( item.parent().css( "flex-direction" ) )
            )
    },

因此,它会检测子元素是否在水平弹性盒子(flex方向为行或行反转)中。我还将tolerance选项设置为pointer,这似乎可以获得最佳结果。

这里是一个CodePen示例:https://codepen.io/edgolub/pen/RzGgWZ


编辑第三方包并不是理想的解决方案。对我而言,有效的方法是保留flexbox样式,但同时在可排序项目上添加float: left样式。float样式不会产生影响,并且允许jQueryUI sortable正常排序。 - Ananda Masri

Christian的答案对我没有起作用,但是却引导我找到了这个解决方案:
activate: function(event, ui) {
   $('.ui-sortable-placeholder').width(ui.item[0].offsetWidth).height(ui.item[0].offsetHeight);
},

看起来插件已经添加了一个具有这个类的占位符。我只需要设置它的大小。否则它会创建一个巨大的占位符并移动所有内容。
