因为有时候会遇到因为有父级的影响事件不生效的情况，所以需要加.native

<el-input
   class="input-new-tag"
   v-model="item.nameValue"
   size="mini"
   placeholder="请输入名称"
   :maxlength="20"
   v-focus
   @keyup.enter.native="nameConfirm(item)"
 >
 </el-input>

有时候层级过多，各元素相互影响，各种原因也会导致entert键无法生效，需要根据情况多设置几个键盘事件来阻止

<el-input
  class="input-new-tag"
   v-model="list.editValue"
   ref="saveTagInput"
   size="small"
   style="line-height:32px;margin-bottom: 0;width:140px;margin-left:0;"
   @click.stop.native="onFocus"
   @keyup.enter.native="onConfirmTag(list)"
   @keyup.enter.stop="onFocus"
   @keydown.enter.stop="onFocus"
   @keyenter.enter.stop="onFocus"
   :maxlength="20"
   v-focus
 >
 </el-input>
