Vuejs2 如何在vue select中设置阻止事件；

在带有“vue选择”的我的Laravel 5.8/vuejs 2.6应用程序中：“^2.6.4”I
选择选项时设置操作，但我有两个问题： 1） 似乎在打开的页面上触发了操作 2） 当我选择选项时，会触发两次操作。 3） 我试图设置。阻止：

<v-select
    v-model="selection_forum_post_action"
    :options="forumPostActionValueArray"
    id="forum_post_action"
    name="forum_post_action"
    class="form-control editable_field"
    placeholder="Select action"
    @change.prevent="forumPostActionSelected(nextThreadPost.id, nextThreadPost.body, nextThreadPost.creator_name)"
></v-select>

我尝试了几种变体，但都失败了。

请举例说明…

我发现@input对我来说很有用：

<v-select
    v-model="selection_forum_post_action"
    :options="forumPostActionValueArray"
    id="forum_post_action"
    name="forum_post_action"
    class="form-control editable_field"
   placeholder="Select action"
   @input="forumPostActionSelected(nextThreadPost.id, nextThreadPost.body, nextThreadPost.creator_name)"
></v-select>

<v-select
    v-model="selection_forum_post_action"
    :options="forumPostActionValueArray"
    id="forum_post_action"
    name="forum_post_action"
    class="form-control editable_field"
   placeholder="Select action"
   @input="forumPostActionSelected(nextThreadPost.id, nextThreadPost.body, nextThreadPost.creator_name)"
></v-select>
