vue拖拽排序插件vuedraggable使用方法详解

大家好，最近做的项目要用到拖拽排序，我现在的项目是vue项目，所以我就屁颠屁颠的去百度有木有这样功能的插件，我就知道一定会有，那就是vuedraggable，这是一款很棒的拖拽插件，下面我来说一下怎么引入

首先在vue项目中，用npm包下载下来

npm install vuedraggable -S

下载下来后，引入插件，在你的vue文件的script标签里面这样引入

import draggable from 'vuedraggable'

别忘了下面要注册组件

components: {
  draggable
},

然后就可以在template标签里面使用了

      
        

          {{element.text}}
        
      
 

下面贴一下详细用法

下面是结果

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

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;
  }
});

好了，今天的介绍就到这里啦，快去试试吧。
