问题描述
我在Nuxt项目中使用vue.draggable。我在某些页面和组件中使用了它,一切都很好。但是在我的一页上,这给了我一个愚蠢的问题!当页面被加载时,它将选择的项目发送到第一个!之后,一切正常!即使我选择并取消选择而不动,事情也能正常进行!! 我试图检查选择的数组是否先移到正确的位置。它工作时,所选择的项目是第一次,如果数组,但如果让我选择别人比第一,2日尝试移动另一项目也! 所以我有点卡住了。
这是代码:
顺便说一下,有些变量和方法像cmsListItems
一样找不到。它们已全局添加到我的项目中
模板:
<draggable v-model="myItemsArray" @end="onEnd" @choose="onChoose" @unchoose="onUnChoose" v-bind="getoptions()">
<transition-group type="transition" name="sortable_transition">
<categorylistcard v-for="(category,index) in cmsListItems"
listtype="cat"
:key="category.id"
:cat="category"
:index="index"
:showforsub="showForSub"
:parentarr="parentArr"
@addnewsub="addNewCat()"
:sub="true"
:sublvl="true"
:sortable="true"
:btntitle="lang.addsubcat"
/>
</transition-group>
</draggable>
脚本:
export default {
data(){
return{
oldindex: '',newIndex: '',dragOptions: {
ghostClass: "sortable_ghost",chosenClass: "sortable_chosen",handle: ".sortable_handle",disabled: false
},isMoved: false,myItemsArray: [],originalItemsArray: [],choosedItem: null
}
},methods:{
// ***** Reorder By Sorting *****\\
this.isMoved = true
this.oldindex = event.oldindex
this.newIndex = event.newIndex
console.log(this.myItemsArray[this.oldindex])
console.log(this.myItemsArray[this.newIndex])
if(this.oldindex !== this.newIndex){
this.dragOptions.disabled = true
let response = await this.axiosGet(`category/reorder/${this.originalItemsArray[this.oldindex].id}/${this.originalItemsArray[this.newIndex].id}`)
if(this.resOk(response.status)){
this.noty(ALERT_TYPE[1],'ok')
this.originalItemsArray = this.myItemsArray
this.isMoved = false
this.dragOptions.disabled = false
this.addClasstoMovedItems(this.oldindex)
this.addClasstoMovedItems(this.newIndex)
this.setCmsListItems(this.myItemsArray)
// this part is my defected solution
setTimeout(() => {
if(this.myItemsArray[this.oldindex].id === this.choosedItem.id || this.myItemsArray[0].id === this.choosedItem.id){
let arrayOfItems = [...this.originalItemsArray]
arrayOfItems.shift()
arrayOfItems.splice(this.newIndex,this.choosedItem)
this.setCmsListItems(arrayOfItems)
this.myItemsArray = [...this.cmsListItems]
}
},50);
// --------------------
}else{
this.isMoved = false
this.myItemsArray = this.originalItemsArray
this.dragOptions.disabled = false
this.addClasstoMovedItems(this.oldindex)
this.addClasstoMovedItems(this.newIndex)
}
}else{
this.isMoved = false
this.myItemsArray = this.originalItemsArray
this.dragOptions.disabled = false
this.addClasstoMovedItems(this.oldindex)
this.addClasstoMovedItems(this.newIndex)
}
},addClasstoMovedItems(index){
if((index == this.oldindex || index == this.newIndex) && this.isMoved == true){
return 'sortable_moved'
}else{
return ''
}
}
},async fetch(){
this.btnLoading = true
let response = await this.axiosGet(`categories/admin/0/1`)
if(this.resOk(response.status)){
if(this.notEmpty(response.data)){
this.setCmsListItems(response.data.items)
this.myItemsArray = [...this.cmsListItems]
this.originalItemsArray = [...this.cmsListItems]
}
this.btnLoading = false
}
},}
解决方法
我有点破解它,所以我不推荐它!
我用@choose
得到了选中的项目,并在我的@end
中检查了数组的第一个索引是否是选中的项目unshift
数组,并将选中的项添加到newIndex
与splice()
像下面这样:
setTimeout(() => {
if(this.myItemsArray[this.oldIndex].id === this.choosedItem.id || this.myItemsArray[0].id === this.choosedItem.id){
let arrayOfItems = [...this.originalItemsArray]
arrayOfItems.shift()
arrayOfItems.splice(this.newIndex,this.choosedItem)
this.setCmsListItems(arrayOfItems)
this.myItemsArray = [...this.cmsListItems]
this.choosedItem = null
}
},1);
