如何将点击卡片的 id 和卡片内容传递给 vue.js 中的另一个组件？

Question

我有三个组件 icons.vue 也包含图标和下拉菜单，这个组件是 DisplayNotes.vue 的子组件，现在当用户点击任何卡片 DeleteNote-option（出现在 icons.vue 内部）时，该卡片id和内容应该传递给另一个组件DeleteNote.vue，如何将特定点击的卡片[visit my output img]1数据传递给DeleteNote.vue组件，请帮我解决这个问题

router.js[deleteNote.vue 的路由路径]

 {
        path:'/trash',
        component:DeleteNote
        },

Answer 1

您需要在路线中激活道具

{
   path: '/trash',
   component: DeleteNote,
   name: 'DeleteNote',
   props: true
 },

将道具传递给图标组件。从图标组件中，使用 router-link 将 cardId 和 cardContent 传递给 DeleteNote 组件。
