表格拖拽Sortable

摘要：支持和任何库例如功能描述用于可重新排序的拖放列表的库。这里是一个关于的例子。更多更多使用方法请参考官方使用示例仓库地址

Sortable 是一个JavaScript库，用于在现代浏览器和触摸设备上重新排序拖放列表。不需要jQuery。支持 Meteor, AngularJS, React, Polymer, Vue, Knockout 和任何CSS库, 例如 Bootstrap.

功能描述: 用于可重新排序的拖放列表的JavaScript库。 （__JavaScript library for reorderable drag-and-drop lists__）

支持触摸设备和现代浏览器(包括IE9)

可以从一个列表拖到另一个列表或在同一个列表中

移动元素时执行CSS动画

支持拖拽处理和可选文本(比voidberg的html5sortable更好)

智能自动滚动

先进的交换检测

使用原生HTML5拖放API构建

支持 Meteor, AngularJS, React, Polymer, Vue, Knockout

支持任何CSS库, 例如 Bootstrap

简单的API

item 1
    
item 2
    
item 3
  

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

您可以对任何列表及其子元素使用，而不仅仅是ul/li。这里是一个关于div的例子。

  var sortable = new Sortable(el, {
    group: "name",  // or { name: "...", pull: [true, false, "clone", array], put: [true, false, array] }
    sort: true,  // sorting inside list
    delay: 0, // time in milliseconds to define when the sorting should start
    touchStartThreshold: 0, // px, how many pixels the point should move before cancelling a delayed drag event
    disabled: false, // Disables the sortable if set to true.
    store: null,  // @see Store
    animation: 150,  // ms, animation speed moving items when sorting, `0` — without animation
    easing: "cubic-bezier(1, 0, 0, 1)", // Easing for animation. Defaults to null. See https://easings.net/ for examples.
    handle: ".my-handle",  // Drag handle selector within list items
    filter: ".ignore-elements",  // Selectors that do not lead to dragging (String or Function)
    preventOnFilter: true, // Call `event.preventDefault()` when triggered `filter`
    draggable: ".item",  // Specifies which items inside the element should be draggable
    ghostClass: "sortable-ghost",  // Class name for the drop placeholder
    chosenClass: "sortable-chosen",  // Class name for the chosen item
    dragClass: "sortable-drag",  // Class name for the dragging item
    dataIdAttr: "data-id",

    swapThreshold: 1, // Threshold of the swap zone
    invertSwap: false, // Will always use inverted swap zone if set to true
    invertedSwapThreshold: 1, // Threshold of the inverted swap zone (will be set to swapThreshold value by default)
    direction: "horizontal", // Direction of Sortable (will be detected automatically if not given)

    forceFallback: false,  // ignore the HTML5 DnD behaviour and force the fallback to kick in

    fallbackClass: "sortable-fallback",  // Class name for the cloned DOM Element when using forceFallback
    fallbackOnBody: false,  // Appends the cloned DOM Element into the Document"s Body
    fallbackTolerance: 0, // Specify in pixels how far the mouse should move before it"s considered as a drag.

    scroll: true, // or HTMLElement
    scrollFn: function(offsetX, offsetY, originalEvent, touchEvt, hoverTargetEl) { ... }, // if you have custom scrollbar scrollFn may be used for autoscrolling
    scrollSensitivity: 30, // px, how near the mouse must be to an edge to start scrolling.
    scrollSpeed: 10, // px
    bubbleScroll: true, // apply autoscroll to all parent elements, allowing for easier movement

    dragoverBubble: false,
    removeCloneOnHide: true, // Remove the clone element when it is not showing, rather than just hiding it
    emptyInsertThreshold: 5, // px, distance mouse must be from empty sortable to insert drag element into it


    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.oldIndex;  // element"s old index within old parent
        evt.newIndex;  // element"s new index within new parent
        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
    }
});
