Vue Draggable не работает с filterBy?
Я использую компонент vue draggable для перетаскивания объектов из одного div в другой. Я также использую filterBy, фильтруя v-model . Проблема в том, что когда я фильтрую (и, например, получаю 1 результат), и пытаюсь перетащить элемент, первый из всех элементов отбрасывается, а не перетаскиваемый элемент.
На нем свои функции отлично работают. Однако при фильтрации результатов он изменяет индекс элементов и при переходе из одного списка в другой — я перемещаю другой элемент, а не тот, который тащил.
Ну, вы должны передать один и тот же список перетаскиваемому компоненту, который вы используете для v-for, — оба требуют отфильтрованного результата.
В настоящее время вы используете метод для работы фильтра. Вы бы дважды назовете этот метод, чтобы получить тот же результат в обоих местах.
Вместо этого вы должны использовать вычисленное свойство, чтобы избежать выполнения одной и той же операции дважды.
Изменение: перетаскиваемый компонент будет мутировать предоставленный список, который не будет влиять на ваши исходные данные при использовании вычисленного свойства.
После просмотра документов для vue-draggable вы, вероятно, должны использовать событие change предоставляемое компонентом (https://github.com/SortableJS/Vue.Draggable#events), для обновления исходных данных.
Я не могу дать вам конкретный пример, потому что я не знаю, какова ваша логика, чтобы определить новую позицию перемещенного элемента в нефильтрованном списке источников.

Draggable vue не работает
Vue component (Vue.js 3.0) allowing drag-and-drop and synchronization with view model array.
Based on and offering all features of Sortable.js
- Full support of Sortable.js features:
- Supports touch devices
- Supports drag handles and selectable text
- Smart auto-scrolling
- Support drag and drop between different lists
- No jQuery dependency
- Keeps in sync HTML and view model list
- Compatible with Vue.js 3.0 transition-group
- Cancellation support
- Events reporting any changes when full control is needed
- Reuse existing UI library components (such as vuetify, element, or vue material etc. ) and make them draggable using tag and componentData props

The item slot should be used to display items of the list. It receives the element value and the element index as slot-props.
With footer slot:
With header slot:
Migrate from vue 2 version:
- Use item slot instead of default to display elements
- Provide a key for items using itemKey props
Breaking changes: 3) When using transition, you should now use the tag props and componentData to create the transition
Type: Array
Required: false
Default: null
Input array to draggable component. Typically same array as referenced by inner element v-for directive.
This is the preferred way to use Vue.draggable as it is compatible with Vuex.
It should not be used directly but only though the v-model directive:
Type: Array
Required: false
Default: null
Alternative to the modelValue prop, list is an array to be synchronized with drag-and-drop.
The main difference is that list prop is updated by draggable component using splice method, whereas modelValue is immutable.
Do not use in conjunction with modelValue prop.
Type: String or Function
Required: true
The property to be used as the element key. Alternatively a function receiving an element of the list and returning its key.
All sortable options
Sortable options can be set directly as vue.draggable props since version 2.19.
This means that all sortable option are valid sortable props with the notable exception of all the method starting by «on» as draggable component expose the same API via events.
kebab-case property are supported: for example ghost-class props will be converted to ghostClass sortable option.
Example setting handle, sortable and a group option:
Type: String
Default: ‘div’
HTML node type of the element that draggable component create as outer element for the included slot.
It is also possible to pass the name of vue component as element. In this case, draggable attribute will be passed to the create component.
See also componentData if you need to set props or event to the created component.
Type: Function
Required: false
Default: (original) => < return original;>
Function called on the source component to clone element when clone option is true. The unique argument is the viewModel element to be cloned and the returned value is its cloned version.
By default vue.draggable reuses the viewModel element, so you have to use this hook if you want to clone or deep clone it.
Type: Function
Required: false
Default: null
If not null this function will be called in a similar way as Sortable onMove callback. Returning false will cancel the drag operation.
evt object has same property as Sortable onMove event, and 3 additional properties:
- draggedContext : context linked to dragged element
- index : dragged element index
- element : dragged element underlying view model element
- futureIndex : potential index of the dragged element if the drop operation is accepted
- relatedContext : context linked to current drag operation
- index : target element index
- element : target element view model element
- list : target list
- component : target VueComponent
Type: Object
Required: false
Default: null
This props is used to pass additional information to child component declared by tag props.
Value: an object corresponding to the attributes, props and events we would pass to the component.
Support for Sortable events:
start , add , remove , update , end , choose , unchoose , sort , filter , clone
Events are called whenever onStart, onAdd, onRemove, onUpdate, onEnd, onChoose, onUnchoose, onSort, onClone are fired by Sortable.js with the same argument.
See here for reference
Note that SortableJS OnMove callback is mapped with the move prop
change event is triggered when list prop is not null and the corresponding array is altered due to drag-and-drop operation.
This event is called with one argument containing one of the following properties:
- added : contains information of an element added to the array
- newIndex : the index of the added element
- element : the added element
- removed : contains information of an element removed from to the array
- oldIndex : the index of the element before remove
- element : the removed element
- moved : contains information of an element moved within the array
- newIndex : the current index of the moved element
- oldIndex : the old index of the moved element
- element : the moved element
The item slot is used to display one element of the list. Vue.draggable will iterate the list and call this slot for each element.
- element the element in the list
- index the element index
It is the only required slot.
Use the header slot to add none-draggable element inside the vuedraggable component. Ex:
Use the footer slot to add none-draggable element inside the vuedraggable component. Ex:

Draggable component should directly wrap the draggable elements, or a transition-component containing the draggable elements.

Limitation: neither header or footer slot works in conjunction with transition-group.
Use the header slot to add none-draggable element inside the vuedraggable component. Important: it should be used in conjunction with draggable option to tag draggable element. Note that header slot will always be added before the default slot regardless its position in the template. Ex:
Use the footer slot to add none-draggable element inside the vuedraggable component. Important: it should be used in conjunction with draggable option to tag draggable elements. Note that footer slot will always be added after the default slot regardless its position in the template. Ex:
Vue.draggable children should always map the list or value prop using a v-for directive
- You may use header and footer slot to by-pass this limitation.
Children elements inside v-for should be keyed as any element in Vue.js. Be carefull to provide revelant key values in particular:
- typically providing array index as keys won’t work as key should be linked to the items content
- cloned elements should provide updated keys, it is doable using the clone props for example
