这篇文章主要为大家详细介绍了vue拖拽排序插件vuedraggable的使用方法,文中示例代码介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们可以参考一下

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,狼蚁网站SEO优化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'

别忘了狼蚁网站SEO优化要注册组件

components: {
 draggable
},

然后就可以在template标签里面使用了

<draggable v-model="colors" @update="datadragEnd" :options = "{animation:500}">
   <transition-group>
    <div v-for="element in colors" :key="element.text" class = "drag-item">
     {{element.text}}
    </div>
   </transition-group>
 </draggable>

狼蚁网站SEO优化贴一下详细用法

<template>
 <draggable v-model="colors" @update="datadragEnd" :options = "{animation:500}">
   <transition-group>
    <div v-for="element in colors" :key="element.text" class = "drag-item">
     {{element.text}}
    </div>
   </transition-group>
 </draggable>
</template>

<script>
 import draggable from 'vuedraggable'
 export default{
  data(){
   return{
    msg:"这是测试组件",
    colors: [
     {
      text: "Aquamarine",
     }, 
     {
      text: "Hotpink",
     }, 
     {
      text: "Gold",
     }, 
     {
      text: "Crimson",
     }, 
     {
      text: "Blueviolet",
     },
     {
      text: "Lightblue",
     }, 
     {
      text: "Cornflowerblue",
     }, 
     {
      text: "Skyblue",
     }, 
     {
      text: "Burlywood",
     }
    ],
    startArr:[],
    endArr:[],
    count:0,
   }
  },
  components: {
    draggable
  },
  methods:{
   getdata (evt) {
    console.log(evt.draggedContext.element.text)
   },
   datadragEnd (evt) {
    evt.preventDefault();
    console.log('拖动前的索引 :' + evt.oldIndex)
    console.log('拖动后的索引 :' + evt.newIndex)
    console.log(this.colors);
   }
  },
  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();
   }
  }
 }
</script>

<style lang="scss" scoped>
 .test{
  border:1px solid #ccc;
 }
 .drag-item{
  width: 200px;
  height: 50px;
  line-height: 50px;
  margin: auto;
  position: relative;
  background: #ddd;
  margin-top:20px;
 }
 .ghostClass{
  opacity: 1;
 }
 .bottom{
  width: 200px;
  height: 50px;
  position: relative;
  background: blue;
  top:2px;
  left: 2px;
  transition: all .5s linear;
 }
</style>

狼蚁网站SEO优化是结果

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,狼蚁网站SEO优化我贴两个地址,一个是vuedraggable的GitHub地址,一个是sortable.js的GitHub地址

vuedraggable: 

sortable.js:

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;
 }
});
