一、draggable 原生拖拽
<div v-for="(item, index) in aiInfoConData"
:key="item"
class="aiInfoConItem"
:draggable="true" //可以拖拽
@dragstart="dragstart(item, index)"
@dragenter="dragenter(item, index)"
@dragend="dragend(item, index)"
>
{{item}}
</div>
const clickVal = ref<string>();
const moveVal = ref<string>();
const endVal = ref<string>();
const dragstart = (val, index1) => {
console.log(val, index1, '11111');
clickVal.value = val;
};
const dragenter = (val, index1) => {
console.log(val, index1, '2222');
moveVal.value = val;
};
const dragend = (val, index1) => {
console.log(val, index1, '3333');
endVal.value = val;
const index = aiInfoConData.value.indexOf(val);
const moveObj = moveVal.value ? moveVal.value : '';
const addIndex = aiInfoConData.value.indexOf(moveObj);
aiInfoConData.value.splice(index, 1);
aiInfoConData.value.splice(addIndex, 0, val);
};
二、使用 Sortable 组件
安装：
npm i sortablejs --save
引入：
import Sortable from 'sortablejs';
- 父级设置id
- 循环遍历中添加
@mouseenter="tipEnter(item.id)" @mouseleave="tipShow = false"
<div id="dragcon" ref="containerBoxScrool" style="padding-top: 20px">
<div
v-for="(item, index) in aiInfoConData"
:key="item"
class="aiInfoConItem sort-btn relative cursor-default"
@mouseenter="tipEnter(item.id)"
@mouseleave="tipShow = false"
>
{{item}}
</div>
</div>
const tipId = ref(0);
const tipEnter = id => {
tipId.value = id; //如果有需要添加id
};
const initSortable = () => {
const el = document.getElementById('dragcon');
// 创建拖拽实例
Sortable.create(el, {
animation: 150,
handle: '.sort-btn',
dragClass: 'sort-active',
chosenClass: 'sort-active',
dataIdAttr: 'id',
// 结束拖动事件
onEnd: ({ newIndex, oldIndex }) => {
//拖动后的操作
const curr = JSON.parse(JSON.stringify(aiInfoConData.value[oldIndex]));
nextTick(() => {
aiInfoConData.value.splice(oldIndex, 1);
aiInfoConData.value.splice(newIndex, 0, curr);
});
const params = {
id: curr.id,
index: newIndex
};
const response: any = writeApi.aiInfo.moveTemp(params);
if (response?.data?.code === '0000') {
ElMessage.success('移动成功');
}
// 调后端接口。。。。。。
}
});
};
onMounted(() => {
nextTick(() => {
initSortable();
});
});
配置项：
var sortable = new Sortable(el, {
group: "name", // or { name: "...", pull: [true, false, 'clone', array], put: [true, false, array] }
sort: true, // boolean 定义是否列表单元是否可以在列表容器内进行拖拽排序
delay: 0, // number 定义鼠标选中列表单元可以开始拖动的延迟时间；
touchStartThreshold: 0, // px, how many pixels the point should move before cancelling a delayed drag event
disabled: false, // boolean 定义是否此sortable对象是否可用，为true时sortable对象不能拖放排序等功能，为false时为可以进行排序，相当于一个开关；
store: null, // @see Store
animation: 150, // ms, number 单位：ms，定义排序动画的时间
easing: "cubic-bezier(1, 0, 0, 1)", // Easing for animation. Defaults to null. See https://easings.net/ for examples.
handle: ".my-handle", // 格式为简单css选择器的字符串，使列表单元中符合选择器的元素成为拖动的手柄，只有按住拖动手柄才能使列表单元进行拖动
filter: ".ignore-elements", // 过滤器，不需要进行拖动的元素
preventOnFilter: true, // 在触发过滤器`filter`的时候调用`event.preventDefault()`
draggable: ".item", // 允许拖拽的项目类名
ghostClass: "sortable-ghost", // drop placeholder的css类名
chosenClass: "sortable-chosen", // 被选中项的css 类名
dragClass: "sortable-drag", // 正在被拖拽中的css类名
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', // 拖拽方向 (默认情况下会自动判断方向)
forceFallback: false, // 忽略 HTML5拖拽行为，强制回调进行
fallbackClass: "sortable-fallback", // 当使用forceFallback的时候，被复制的dom的css类名
fallbackOnBody: false, // 将cloned DOM 元素挂到body元素上。
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
},
// 元素被选中
onChoose: function (/**Event*/evt) {
evt.oldIndex; // element index within parent
},
// 元素未被选中的时候（从选中到未选中）
onUnchoose: function(/**Event*/evt) {
// same properties as onEnd
},
// 开始拖拽的时候
onStart: function (/**Event*/evt) {
evt.oldIndex; // element index within parent
},
// 结束拖拽
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
},
// 元素从一个列表拖拽到另一个列表
onAdd: function (/**Event*/evt) {
// same properties as onEnd
},
// 列表内元素顺序更新的时候触发
onUpdate: function (/**Event*/evt) {
// same properties as onEnd
},
// 列表的任何更改都会触发
onSort: function (/**Event*/evt) {
// same properties as onEnd
},
// 元素从列表中移除进入另一个列表
onRemove: function (/**Event*/evt) {
// same properties as onEnd
},
// 试图拖拽一个filtered的元素
onFilter: function (/**Event*/evt) {
var itemEl = evt.item; // HTMLElement receiving the `mousedown|tapstart` event.
},
// 拖拽移动的时候
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
},
// clone一个元素的时候触发
onClone: function (/**Event*/evt) {
var origEl = evt.item;
var cloneEl = evt.clone;
},
// 拖拽元素改变位置的时候
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
}
