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'
注册组件
components: {
draggable
},
vuedraggable.common.js?bb80:2942 Options props is deprecated, add sortable options directly as vue.draggable item, or use v-bind. 出现警告 :options (选项道具已经弃用) 改成 v-bind
{{element.text}}
options配置如下
group: "name", // or { name: "...", pull: [true, false, clone], put: [true, false, array] } name相同的组可以互相拖动
sort: true, // 内部排序列表
delay: 0, // 以毫秒为单位定义排序何时开始。
touchStartThreshold: 0, // px,在取消延迟拖动事件之前,点应该移动多少像素?
disabled: false, // 如果设置为真,则禁用sortable。
store: null, // @see Store
animation: 150, // ms, 动画速度运动项目排序时,' 0 ' -没有动画。
handle: ".my-handle", // 在列表项中拖动句柄选择器。
filter: ".ignore-elements", // 不导致拖拽的选择器(字符串或函数)
preventOnFilter: true, // 调用“event.preventDefault()”时触发“filter”
draggable: ".item", // 可拖拽item的class名
ghostClass: "sortable-ghost", // 设置拖动元素的class的占位符的类名。
chosenClass: "sortable-chosen", // 设置被选中的元素的class
dragClass: "sortable-drag", //拖动元素的class。
dataIdAttr: 'data-id',
forceFallback: false, // 忽略HTML5的DnD行为,并强制退出。(h5里有个属性也是拖动,这里是为了去掉H5拖动对这个的影响)
fallbackClass: "sortable-fallback", // 使用forceFallback时克隆的DOM元素的类名。
fallbackOnBody: false, // 将克隆的DOM元素添加到文档的主体中。(默认放在被拖动元素的同级)
fallbackTolerance: 0, // 用像素指定鼠标在被视为拖拽之前应该移动的距离。
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;
}
然后会出现这个问题 transition-group 内绑定key index无效
:key="'my-name'+index" 就可以了
