這個問題卡了我一下午, 一直找不到答案, 然後用谷歌瀏覽器,解決一分鐘就解決了,
就用 table transition-group 搜索 裏面前三都是答案,
我本人立帖爲證 以後查問題,不在百度 直接去谷歌瀏覽 . 如若違反判定跑步4公里.
在看的朋友如有我的毛病,請及時改正.
我之前是這麼寫的:
<table class="table table-bordered table-hover table-striped">
<thead>
<tr>
<th>id</th>
<th>Name</th>
<th>Ctime</th>
<th>Operation</th>
</tr>
</thead>
< transition-group" >
<tr v-for="item,index in list" :key="item.id">
<td>{{item.id}}</td>
<td>{{item.name}}</td>
<td>{{item.ctime}}</td>
<td style="color: #0e9aef"><a href="#">刪除</a></td>
</tr>
</transition-group>
</table>
官方文檔的解釋:解析 DOM 模板時的注意事項原來,在table裏使用的時候,生成的真實元素之所以 會脫離table標籤,並插到了table標籤前,是因爲 這個 組件會被作爲無效的內容提升到外部,並導致最終渲染結果出錯。這裏官方文檔給出了一個解決辦法:特殊特性 is :
結果很明顯就是 用is 擺脫 默認行爲,以至於不讓他往外偏離.
