Vue警告-无法读取未定义的属性indexOf

Question

首先，我在stackoverlow上看到了很多类似的问题，但没有人与这个例子相关......

我正在开发 Vue JS 项目 + Laravel，所以一切进展顺利，但突然出现无法解决的错误（从我的角度来看，一切都是正确的）。

基本上我也在使用 Vuesax 库。

所以我有带有编辑按钮@click="editProject(project) 的项目表，调用的方法是...

editProject(project) {
    let membersIds = []
    let teamsIds = []

    project.members.forEach(member => membersIds.push(member.id))
    project.groups.forEach(team => teamsIds.push(team.id))

    this.editProjectData = {
        name: project.name,
        start_date: project.start_date,
        deadline: project.deadline,
        members: membersIds,
        teams: teamsIds,
        status: project.status,
        priority: project.priority,
        description: project.description,
        color: project.color,
        visibility: project.visibility
    }
    this.showEditProject = true
}

所以在那一刻...showEditProject = true 会给我带来由props 数据填写的表单

<transition name="slide-right">
    <EditProject :project-data="editProjectData" :all-statuses="allStatuses" :all-priorities="allPriorities" :all-colors="allColors" :all-members="allMembers" :all-teams="allTeams" v-show="showEditProject"/>
</transition>

所以我正在遍历数据（状态、颜色、优先级、成员、团队）并填写表格。

所以优先级没有任何问题，状态和颜色也是如此，但我对成员和团队有问题。

<div class="w-full mb-3">
    <vs-select multiple :label="$t('work.projects.edit-project-modal.members')" v-model="projectData.members" color="#91C959" style="width: 100%;">
        <vs-select-item :key="member.id" :value="member.id" :text="member.firstname + ' ' + member.lastname" v-for="member in allMembers" />
    </vs-select>
</div>

同样的方法适用于所有人，但只有在成员和团队可用时才会出现错误 - 如果我评论他们 - 没问题。 每个成员/团队有 4 个错误（如下）

[Vue warn]: Error in render: "TypeError: Cannot read property 'indexOf' of undefined"

数据显示没有任何问题 - 因此表单已正确填写，但控制台 i 充满了前面解释的错误。

更新： EditProject 组件中的道具（Modal）

props: {
    projectData: {},
    allStatuses: {},
    allColors: {},
    allPriorities: {},
    allMembers: {},
    allTeams: {}
}

Answer 1

基本上在对代码进行了良好的审查和研究之后，我发现EditProject modal 显示了，但是由于没有传递数据，因此在尝试循环未定义的成员和团队时会导致错误。

如此简单的解决方案，为了防止 EditProject 组件/模态被加载，我还添加了 v-if="showEditProject"

<transition name="slide-right">
    <EditProject v-if="showEditProject" v-show="showEditProject" :project-data="editProjectData" :all-statuses="allStatuses" :all-priorities="allPriorities" :all-colors="allColors" :all-members="allMembers" :all-teams="allTeams"/>
</transition>
