如何在 vue.js 中将卡片数据从一个组件绑定到另一个组件卡片?
【中文标题】如何在 vue.js 中将卡片数据从一个组件绑定到另一个组件卡片?【英文标题】:How to bind card data from one component to another component card in vue.js? 【发布时间】:2021-09-04 11:37:35 【问题描述】:我有两个组件,一个是显示卡,它负责将数据显示到来自后端(DisplayNotes.vue)的卡中,另一个是通过打开弹出窗口(updateNotes.vue)来更新现有数据卡,如果用户单击任何卡片会打开一个弹出窗口,该弹出窗口负责编辑数据,但在我的情况下,如果用户单击任何卡片,它应该打开弹出卡片(UpdateNotes.vue)以及现有数据,我的问题是如何从卡中获取数据到弹出卡中[Here i am clicking 4th card ,when ever i click on the forth card the content should bind to the pop-up card]1,请帮我将数据到弹出卡中
DisplayNotes.vue

return

, ],
clickedCard:'',
,
methods:
Togglebtn()
this.flag = !this.flag;
,
async handlesubmit()
service.userDisplayNotes().then(response =>
this.notes.push(...response.data);
)
,
toggle(id)
var blur=document.getElementById('blur');
blur.classList.toggle('active');
this.clickedCard = id;
var popup=document.getElementById('popup');
popup.classList.toggle('active');

【问题讨论】:
【参考方案1】:当您在弹出窗口中传递卡片的 id 时,同样在弹出窗口中传递当前点击卡片的数据。

【讨论】:
你好@Yash Maheshwari,数据没有以 UpdateNotes.vue 中的 placeholder="Title" 和 "Take a Note" 的形式绑定 如果我点击任何一张卡片,它会打开一个弹出窗口(updateNotes.vue),在我的情况下,我需要包含卡片的内容,数据将出现在弹出卡片中,@Yash Maheshwari跨度> 你能通过console.log(this.cardContent)检查你在created()
钩子中得到了什么吗?
你好@Yash Maheshwari,我正在控制台上获取点击卡片的数据,我正在切换(id)内的 DisplayNotes.vue 中编写 console.log()
TypeError: Cannot read property 'title' of undefined at VueComponent.created
那是因为cardContent
从未设置过值以上是关于cmd输入vue弹出一个对话框让我打开vue.js是怎么回事?的主要内容,如果未能解决你的问题,请参考以下文章
