Usage

<ul id="items">
    <li>item 1</li>
    <li>item 2</li>
    <li>item 3</li>
</ul>


var el = document.getElementById('items');
var sortable = Sortable.create(el);

You can use any element for the list and its elements, not just ul/li. Here is an example with divs.

[译]您可以对列表及其元素使用任何元素,而不仅仅是ul/li。 这是一个使用div的示例

    setData: function (/** DataTransfer */dataTransfer, /** HTMLElement*/dragEl) {
        dataTransfer.setData('Text', dragEl.textContent); // `dataTransfer` object of HTML5 DragEvent
    },

    // Element is chosen
    onChoose: function (/**Event*/evt) {
        evt.oldIndex;  // element index within parent
    },

    // Element is unchosen
    onUnchoose: function(/**Event*/evt) {
        // same properties as onEnd
    },

    // Element dragging started
    onStart: function (/**Event*/evt) {
        evt.oldIndex;  // element index within parent
    },

    // Element dragging ended
    onEnd: function (/**Event*/evt) {
        var itemEl = evt.item;  // dragged HTMLElement
        evt.to;    // target list
        evt.from;  // previous list

        evt.clone // the clone element
        evt.pullMode;  // when item is in another sortable: `"clone"` if cloning, `true` if moving
    },

    // Element is dropped into the list from another list
    onAdd: function (/**Event*/evt) {
        // same properties as onEnd
    },

    // Changed sorting within list
    onUpdate: function (/**Event*/evt) {
        // same properties as onEnd
    },

    // Called by any change to the list (add / update / remove)
    onSort: function (/**Event*/evt) {
        // same properties as onEnd
    },

    // Element is removed from the list into another list
    onRemove: function (/**Event*/evt) {
        // same properties as onEnd
    },

    // Attempt to drag a filtered element
    onFilter: function (/**Event*/evt) {
        var itemEl = evt.item;  // HTMLElement receiving the `mousedown|tapstart` event.
    },

    // Event when you move an item in the list or between lists
    onMove: function (/**Event*/evt, /**Event*/originalEvent) {
        // Example: https://jsbin.com/nawahef/edit?js,output
        evt.dragged; // dragged HTMLElement
        evt.draggedRect; // DOMRect {left, top, right, bottom}
        evt.related; // HTMLElement on which have guided
        evt.relatedRect; // DOMRect
        evt.willInsertAfter; // Boolean that is true if Sortable will insert drag element after target by default
        originalEvent.clientY; // mouse position
        // return false; — for cancel
        // return -1; — insert before target
        // return 1; — insert after target
    },

    // Called when creating a clone of element
    onClone: function (/**Event*/evt) {
        var origEl = evt.item;
        var cloneEl = evt.clone;
    },

    // Called when dragging element changes position
    onChange: function(/**Event*/evt) {
        evt.newIndex // most likely why this event is used is to get the dragging element's current index
        // same properties as onEnd
    }
});

group option

To drag elements from one list into another, both lists must have the same group value. You can also define whether lists can give away, give and keep a copy (clone), and receive elements.

  • name: String — group name
  • pull: true|false|["foo", "bar"]|'clone'|function — ability to move from the list. clone — copy the item, rather than move. Or an array of group names which the elements may be put in. Defaults to true.
  • put: true|false|["baz", "qux"]|function — whether elements can be added from other lists, or an array of group names from which elements can be added.
  • revertClone: boolean — revert cloned element to initial position after moving to a another list.

[译]要将元素从一个列表拖到另一个列表中,两个列表必须具有相同的group值。 您还可以定义列表是否可以放弃,给予和保留副本(clone)以及接收元素。

  • name:String—组名
  • pull:true|false|["foo", "bar"]|'clone'|function-从列表中移出的能力。clone—复制项目,而不是移动。 或元素可以放入的一组组名。默认为true
  • put:true|false|["baz", "qux"]|function —是否可以从其他列表中添加元素,或者可以从中添加元素的组名数组。
  • revertClone: boolean —将克隆的元素移动到另一个列表后将其还原到初始位置。

Demo:


sort option

Allow sorting inside list.

[译]允许在列表内排序。

Demo: https://jsbin.com/jayedig/edit?js,output


delay option

Time in milliseconds to define when the sorting should start. Unfortunately, due to browser restrictions, delaying is not possible on IE or Edge with native drag & drop.

[译]定义排序开始时间的时间(以毫秒为单位)。 不幸的是,由于浏览器的限制,无法通过本地拖放在IE或Edge上进行延迟。

Demo: https://jsbin.com/zosiwah/edit?js,output


delayOnTouchOnly option

Whether or not the delay should be applied only if the user is using touch (eg. on a mobile device). No delay will be applied in any other case. Defaults to false.

[译]是否仅在用户使用触摸(例如在移动设备上)时才应应用延迟。 在任何其他情况下,都不会延迟。 默认为false


swapThreshold option

Percentage of the target that the swap zone will take up, as a float between 0 and 1.

[译]交换区域将占用的目标百分比,介于01之间。

Read more

Demo: http://sortablejs.github.io/Sortable#thresholds


invertSwap option

Set to true to set the swap zone to the sides of the target, for the effect of sorting "in between" items.

[译]设置为true可以将交换区域设置在目标的侧面,以实现在项目之间“in between”的效果。

Read more

Demo: http://sortablejs.github.io/Sortable#thresholds


invertedSwapThreshold option

Percentage of the target that the inverted swap zone will take up, as a float between 0 and 1. If not given, will default to swapThreshold.

[译]反向交换区域将占据的目标百分比,介于01之间的浮点数。如果未指定,则默认为swapThreshold

Read more


direction option

Direction that the Sortable should sort in. Can be set to 'vertical', 'horizontal', or a function, which will be called whenever a target is dragged over. Must return 'vertical' or 'horizontal'.

[译]Sortable应该排序的方向。可以设置为'vertical''horizontal'或函数,只要将目标拖到上方,就会调用该函数。 必须返回'vertical''horizontal'

Read more

Example of direction detection for vertical list that includes full column and half column elements:

[译]垂直列表的方向检测示例,其中包括整列和半列元素:

Sortable.create(el, {
    direction: function(evt, target, dragEl) {
        if (target !== null &amp;&amp; target.className.includes('half-column') &amp;&amp; dragEl.className.includes('half-column')) {
            return 'horizontal';
        }
        return 'vertical';
    }
});

touchStartThreshold option

This option is similar to fallbackTolerance option.

When the delay option is set, some phones with very sensitive touch displays like the Samsung Galaxy S8 will fire unwanted touchmove events even when your finger is not moving, resulting in the sort not triggering.

This option sets the minimum pointer movement that must occur before the delayed sorting is cancelled.

Values between 3 to 5 are good.

[译]此选项类似于fallbackTolerance选项。

设置delay选项后,即使手指不动,某些具有非常敏感的触摸显示屏的手机(如三星Galaxy S8)也会触发不需要的触摸移动事件,从而导致排序不会触发。

此选项设置取消延迟排序之前必须发生的最小指针移动。

3到5之间的值是好的。


disabled options

Disables the sortable if set to true.

[译]如果设置为true,则禁用sortable。

Demo: https://jsbin.com/sewokud/edit?js,output

var sortable = Sortable.create(list);

document.getElementById("switcher").onclick = function () {
    var state = sortable.option("disabled"); // get

    sortable.option("disabled", !state); // set
};

handle option

To make list items draggable, Sortable disables text selection by the user. That's not always desirable. To allow text selection, define a drag handler, which is an area of every list element that allows it to be dragged around.

[译]为了使列表项可拖动,Sortable可禁用用户的文本选择。 这并不总是可取的。 要允许选择文本,需要定义一个拖动handler,该handler是每个列表元素都可以在其中拖动的区域。

Demo: https://jsbin.com/numakuh/edit?html,js,output

Sortable.create(el, {
    handle: ".my-handle"
});


<ul>
    <li><span class="my-handle">::</span> list item text one
    </li><li><span class="my-handle">::</span> list item text two
</li></ul>


.my-handle {
    cursor: move;
    cursor: -webkit-grabbing;
}

filter option

Sortable.create(list, {
    filter: ".js-remove, .js-edit",
    onFilter: function (evt) {
        var item = evt.item,
            ctrl = evt.target;

        if (Sortable.utils.is(ctrl, ".js-remove")) {  // Click on remove button
            item.parentNode.removeChild(item); // remove sortable item
        }
        else if (Sortable.utils.is(ctrl, ".js-edit")) {  // Click on edit link
            // ...
        }
    }
})

ghostClass option

Class name for the drop placeholder (default sortable-ghost).

[译]放置占位符的类名称(默认为sortable-ghost)。

Demo: https://jsbin.com/henuyiw/edit?css,js,output

.ghost {
  opacity: 0.4;
}


Sortable.create(list, {
  ghostClass: "ghost"
});

chosenClass option

Class name for the chosen item (default sortable-chosen).

[译]所选项目的类名称(默认为sortable-chosen)。

Demo: https://jsbin.com/hoqufox/edit?css,js,output

.chosen {
  color: #fff;
  background-color: #c00;
}


Sortable.create(list, {
  delay: 500,
  chosenClass: "chosen"
});

forceFallback option

If set to true, the Fallback for non HTML5 Browser will be used, even if we are using an HTML5 Browser. This gives us the possibility to test the behaviour for older Browsers even in newer Browser, or make the Drag 'n Drop feel more consistent between Desktop , Mobile and old Browsers.

On top of that, the Fallback always generates a copy of that DOM Element and appends the class fallbackClass defined in the options. This behaviour controls the look of this 'dragged' Element.

[译]如果设置为true,则即使我们使用的是HTML5浏览器,也将使用非HTML5浏览器的Fallback。 这使我们能够测试旧版浏览器的行为,甚至是在新版浏览器中,也可以使桌面浏览器,移动版浏览器和旧版浏览器之间的拖放感觉更加一致。

最重要的是,Fallback始终会生成该DOM元素的副本,并附加在选项中定义的fallbackClass类。 此行为控制此“拖动”元素的外观。

Demo: https://jsbin.com/sibiput/edit?html,css,js,output


fallbackTolerance option

Emulates the native drag threshold. Specify in pixels how far the mouse should move before it's considered as a drag. Useful if the items are also clickable like in a list of links.

When the user clicks inside a sortable element, it's not uncommon for your hand to move a little between the time you press and the time you release. Dragging only starts if you move the pointer past a certain tolerance, so that you don't accidentally start dragging every time you click.

3 to 5 are probably good values.

[译]模拟本地拖动阈值。 指定以像素为单位的鼠标在被视为拖动之前应移动的距离。 如果项目也可以单击,例如在链接列表中,则很有用。

当用户在可排序元素内单击时,在按下和松开之间,您的手通常会略微移动。 仅当您将指针移过一定的公差时才开始拖动,这样您就不会在每次单击时意外开始拖动。

3到5可能是不错的值。


dragoverBubble option

If set to true, the dragover event will bubble to parent sortables. Works on both fallback and native dragover event. By default, it is false, but Sortable will only stop bubbling the event once the element has been inserted into a parent Sortable, or can be inserted into a parent Sortable, but isn't at that specific time (due to animation, etc).

Since 1.8.0, you will probably want to leave this option as false. Before 1.8.0, it may need to be true for nested sortables to work.

[译]如果设置为true,则拖动事件将冒泡到父可排序对象。 适用于fallback和本机拖动事件。 默认情况下,它为false,但是Sortable仅在将元素插入到父Sortable中或_可以_插入到父Sortable中后才停止冒泡事件,但不在特定时间(由于动画等) 。

从1.8.0开始,您可能希望将此选项保留为false。 在1.8.0之前,嵌套可排序项可能必须为true才能工作。


removeCloneOnHide option

If set to false, the clone is hidden by having it's CSS display property set to none. By default, this option is true, meaning Sortable will remove the cloned element from the DOM when it is supposed to be hidden.

[译]如果设置为false,则通过将其CSSdisplay属性设置为none来隐藏克隆。 默认情况下,此选项为true,这意味着Sortable在应隐藏的情况下将从DOM中删除克隆的元素。


emptyInsertThreshold option

The distance (in pixels) the mouse must be from an empty sortable while dragging for the drag element to be inserted into that sortable. Defaults to 5. Set to 0 to disable this feature.

[译]拖动时鼠标必须与一个空的可排序对象之间的距离(以像素为单位),以便将拖动元素插入到该可排序对象中。 默认值为5。设置为0以禁用此功能。

Demo: https://jsbin.com/becavoj/edit?js,output
