我最近一直在使用UI，我真的很想使用Flexbox CSS来控制布局。我需要一种方法来制作我可以排序和拖动的盒子。
我首先尝试了 jQueryUI的可排序，但它似乎并不适用于flexbox。 它确实排序，但我认为它在新位置的可放置时会出现一些计算误差吗？或者我做错了。 无论哪种方式，我都会提供我的代码和JSFiddle，这样你就可以看到自己的怪异。我正在寻找的行为是很好的干净的可放置占位符，并且对齐就像jQueryUI的例子一样。 测试图例上的点击和拖动。同时尝试将最左边的项目拖到最右边。
如何解决这个问题，以便它可以与Flexbox一起使用？

答案 0 :(得分：5)
使用一些可排序的事件处理程序来创建一个＆＃34; ghost＆＃34;元素代替您正在移动的元素。这有助于保持弹性计算。
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();
});
答案 1 :(得分：1)
jQuery可排序DOES可以处理这样的水平列表，但是要激活该行为，它将查找项目为float: left|right;，display: inline;或display: table-cell;。这是在jQuery UI 1.12.1中进行检查的地方
_isFloating: function( item ) {
return ( /left|right/ ).test( item.css( "float" ) ) ||
( /inline|table-cell/ ).test( item.css( "display" ) );
},
我对您的代码应用了float: left;，我认为它现在的表现要好一些：
https://jsfiddle.net/1s24xpzu/
这不是一个漂亮的解决方案，因为我们基本上只是在欺骗jQuery，并且可能会产生意想不到的浮动结果。但是我认为它至少对我的用例有用。
答案 2 :(得分：0)
对于那些像我这样偶然发现的人：
我的用例是我想对在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，但他们什么也没做。我还尝试将浮点数添加到第一个元素（因为它可以检测到），但这并没有太大帮助。
我所做的是更改isFloat函数（请注意，应将其称为isHorizontalSort），如下所示：
_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" ) )
)
},
因此它检测子项是否在水平flexbox内（flex方向是行还是行反向）。我也将tolerance选项设置为pointer，这似乎能带来最佳效果。
