vue拖拽排序插件vuedraggable使用方法详解

HTML引用（vue引用随便百度都有在此不做简介）

注册组件

components: { vuedraggable },

vue.js 2.0 html引用好像只能加载“vuedraggable”，如果是“draggable”会报错找不到，不知道为什么希望有大神能够指点一下

示例

写此文章主要是为了这个（确实真实可用）

mounted () {
    //为了防止火狐浏览器拖拽的时候以新标签打开，此代码真实有效
    document.body.ondrop = function (event) {
        event.preventDefault();
        event.stopPropagation();
    }
}

上下是可以拖动的，只是截图的话看不出效果来，小伙伴们注意了，里面有个options选项，这个选项怎么来的呢，据我观察这个插件是基于sortable.js，所以这个options里面的配置，和sortable.js是一样的，下面我贴两个地址，一个是vuedraggable的GitHub地址，一个是sortable.js的GitHub地址

sortable.js:学习地址

options配置如下

var sortable = new Sortable(el, {
  group: "name", // or { name: "...", pull: [true, false, clone], 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
  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',
 
  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
 
  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 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
  },
 
  // 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: http://jsbin.com/tuyafe/1/edit?js,output
    evt.dragged; // dragged HTMLElement
    evt.draggedRect; // TextRectangle {left, top, right и bottom}
    evt.related; // HTMLElement on which have guided
    evt.relatedRect; // TextRectangle
    originalEvent.clientY; // mouse position
    // return false; — for cancel
  },
 
  // Called when creating a clone of element
  onClone: function (/**Event*/evt) {
    var origEl = evt.item;
    var cloneEl = evt.clone;
  }
});
