【问题描述】：
我有一个项目的 json 文件，其中一家公司可以执行多个项目，而其他一些公司只执行一个项目。我希望能够在公司徽标为 click 时显示项目。默认情况下，项目是隐藏的，直到单击公司的图标。我有一个 vue if 绑定来显示是否单击和一个组件来显示项目。 我如何调整我的代码来做到这一点。我的代码如下所示：
<div class="container" v-if="seen">
<header class="section-header">
<h3>{{ projects }}</h3>
</header>
<div class="row" id="display-projects">
<project-executed
v-for="project in projects"
v-icon="project.icon"
v-icon-color="project.color"
v-title="project.title"
v-description="project.description"
></project-executed>
</div>
</div>
const app = Vue.createApp({
data() {
return {
seen: false,
projects: "Projects",
unicef:[

在徽标上添加
@click以触发相应的方法 -
非常感谢@Daniel_Knights 我认为问题是因为我错误地添加了绑定属性。我使用的是 v-item 而不是 :item.
