我在我的 Nuxt 项目中使用 Vue.Draggable。我在一些页面和组件中使用了它,一切都很好。但在我的一个页面上,它给了我一个愚蠢的问题!加载页面时,它将所选项目发送到第一个!之后一切正常!即使我选择和取消选择而不移动,一切正常!我试图检查选择的数组是否再次正确移动它。当所选项目是第一个 if 数组时它起作用,但如果我选择第一个而不是第一个,第二次尝试它也移动另一个项目!所以我有点卡住了。
这是代码:顺便说一句,有些变量和方法你找不到它们cmsListItems
。它们被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"
/>
